这一切都很棒，但为什么不让它变得更简单呢?

不久前我也遇到过这种情况……和android touchlistener工作得很好，但在使用上有限制..我找到了另一个解决方案，我希望能帮助你:

    <LinearLayout
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/zero_row">
    <LinearLayout
        android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <LinearLayout
            android:orientation="horizontal"
            android:layout_width="wrap_content"
            android:layout_height="match_parent">
            <ProgressBar
                android:id="@+id/loadingProgressBar"
                android:layout_gravity="center"
                android:layout_width="28dp"
                android:layout_height="28dp" />
        </LinearLayout>
        <LinearLayout
            android:orientation="horizontal"
            android:layout_width="match_parent"
            android:background="@drawable/edittext_round_corners"
            android:layout_height="match_parent"
            android:layout_marginLeft="5dp">
            <ImageView
                android:layout_width="28dp"
                android:layout_height="28dp"
                app:srcCompat="@android:drawable/ic_menu_search"
                android:id="@+id/imageView2"
                android:layout_weight="0.15"
                android:layout_gravity="center|right"
                android:onClick="OnDatabaseSearchEvent" />
            <EditText
                android:minHeight="40dp"
                android:layout_marginLeft="10dp"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:background="@drawable/edittext_round_corners"
                android:inputType="textPersonName"
                android:hint="Search.."
                android:textColorHint="@color/AndroidWhite"
                android:textColor="@color/AndroidWhite"
                android:ems="10"
                android:id="@+id/e_d_search"
                android:textCursorDrawable="@color/AndroidWhite"
                android:layout_weight="1" />
            <ImageView
                android:layout_width="28dp"
                android:layout_height="28dp"
                app:srcCompat="@drawable/ic_oculi_remove2"
                android:id="@+id/imageView3"
                android:layout_gravity="center|left"
                android:layout_weight="0.15"
                android:onClick="onSearchEditTextCancel" />
        </LinearLayout>

        <!--android:drawableLeft="@android:drawable/ic_menu_search"-->
        <!--android:drawableRight="@drawable/ic_oculi_remove2"-->

    </LinearLayout>

</LinearLayout>

现在您可以创建ImageClick侦听器或事件，并对文本做任何您想做的事情。这个edittext_round_corners.xml文件

<item android:state_pressed="false" android:state_focused="false">
    <shape>
        <gradient
            android:centerY="0.2"
            android:startColor="@color/colorAccent"
            android:centerColor="@color/colorAccent"
            android:endColor="@color/colorAccent"
            android:angle="270"
            />
        <stroke
            android:width="0.7dp"
            android:color="@color/colorAccent" />
        <corners
            android:radius="5dp" />
    </shape>
</item>

我认为如果我们使用一些技巧会容易得多:)

用图标创建一个图像按钮，并设置其背景 颜色要透明。 将图像按钮放在EditText和右边 实现按钮的onclick侦听器来执行您的 函数

Done

实际上，您不需要扩展任何类。假设我有一个EditText editComment和一个drawableRight

editComment.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        final int DRAWABLE_LEFT = 0;
        final int DRAWABLE_TOP = 1;
        final int DRAWABLE_RIGHT = 2;
        final int DRAWABLE_BOTTOM = 3;

        if(event.getAction() == MotionEvent.ACTION_UP) {
            if(event.getRawX() >= (editComment.getRight() - editComment.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
                // your action here

                return true;
            }
        }
        return false;
    }
});

我们getRawX()，因为我们想要得到实际的触摸在屏幕上的位置，而不是相对于父。

要获得左侧点击

if(event.getRawX() <= (editComment.getCompoundDrawables()[DRAWABLE_LEFT].getBounds().width())) 

分享我的处理TextView复合可绘制的点击和触摸事件的通用解决方案。

首先，我们需要一个触摸事件处理程序:

/**
 * Handles compound drawable touch events.
 * Will intercept every event that happened inside (calculated) compound drawable bounds, extended by fuzz.
 * @see TextView#getCompoundDrawables()
 * @see TextView#setCompoundDrawablesRelativeWithIntrinsicBounds(int, int, int, int)
 */
public abstract class CompoundDrawableTouchListener implements View.OnTouchListener {

    private final String LOG_TAG = "CmpDrawableTouch";

    private final int fuzz;

    public static final int LEFT = 0;
    public static final int TOP = 1;
    public static final int RIGHT = 2;
    public static final int BOTTOM = 3;
    private static final int[] DRAWABLE_INDEXES = {LEFT, TOP, RIGHT, BOTTOM};

    /**
     * Default constructor
     */
    public CompoundDrawableTouchListener() {
        this(0);
    }

    /**
     * Constructor with fuzz
     * @param fuzz desired fuzz in px
     */
    public CompoundDrawableTouchListener(int fuzz) {
        this.fuzz = fuzz;
    }

    @Override
    public boolean onTouch(View view, MotionEvent event) {
        if (!(view instanceof TextView)) {
            Log.e(LOG_TAG, "attached view is not instance of TextView");
            return false;
        }

        TextView textView = (TextView) view;
        Drawable[] drawables = textView.getCompoundDrawables();
        int x = (int) event.getX();
        int y = (int) event.getY();

        for (int i : DRAWABLE_INDEXES) {
            if (drawables[i] == null) continue;
            Rect bounds = getRelativeBounds(i, drawables[i], textView);
            Rect fuzzedBounds = addFuzz(bounds);

            if (fuzzedBounds.contains(x, y)) {
                MotionEvent relativeEvent = MotionEvent.obtain(
                    event.getDownTime(),
                    event.getEventTime(),
                    event.getAction(),
                    event.getX() - bounds.left,
                    event.getY() - bounds.top,
                    event.getMetaState());
                return onDrawableTouch(view, i, bounds, relativeEvent);
            }
        }

        return false;
    }

    /**
     * Calculates compound drawable bounds relative to wrapping view
     * @param index compound drawable index
     * @param drawable the drawable
     * @param view wrapping view
     * @return {@link Rect} with relative bounds
     */
    private Rect getRelativeBounds(int index, @NonNull Drawable drawable, View view) {
        Rect drawableBounds = drawable.getBounds();
        Rect bounds = new Rect();

        switch (index) {
            case LEFT:
                bounds.offsetTo(view.getPaddingLeft(),
                    view.getHeight() / 2 - bounds.height() / 2);
                break;

            case TOP:
                bounds.offsetTo(view.getWidth() / 2 - bounds.width() / 2,
                    view.getPaddingTop());
                break;

            case RIGHT:
                bounds.offsetTo(view.getWidth() - view.getPaddingRight() - bounds.width(),
                    view.getHeight() / 2 - bounds.height() / 2);
                break;

            case BOTTOM:
                bounds.offsetTo(view.getWidth() / 2 - bounds.width() / 2,
                    view.getHeight() - view.getPaddingBottom() - bounds.height());
                break;
        }

        return bounds;
    }

    /**
     * Expands {@link Rect} by given value in every direction relative to its center
     * @param source given {@link Rect}
     * @return result {@link Rect}
     */
    private Rect addFuzz(Rect source) {
        Rect result = new Rect();
        result.left = source.left - fuzz;
        result.right = source.right + fuzz;
        result.top = source.top - fuzz;
        result.bottom = source.bottom + fuzz;
        return result;
    }

    /**
     * Compound drawable touch-event handler
     * @param v wrapping view
     * @param drawableIndex index of compound drawable which recicved the event
     * @param drawableBounds {@link Rect} with compound drawable bounds relative to wrapping view.
     * Fuzz not included
     * @param event event with coordinated relative to wrapping view - i.e. within {@code drawableBounds}.
     * If using fuzz, may return negative coordinates.
     */
    protected abstract boolean onDrawableTouch(View v, int drawableIndex, Rect drawableBounds, MotionEvent event);
}

现在你可以处理任何触摸事件任何复合drawable的任何TextView你喜欢这样:

textView1.setOnTouchListener(new CompoundDrawableTouchListener() {
            @Override
            protected void onDrawableTouch(View v, int drawableIndex, Rect drawableBounds, MotionEvent event) {
                switch(v.getId()) {
                    case R.id.textView1:
                        switch(drawableIndex) {
                            case CompoundDrawableTouchListener.RIGHT:
                                doStuff();
                                break;
                        }
                        break;
                }
            }
        });

只对点击感兴趣?只需通过MotionEvent动作过滤:

/**
 * Handles compound drawable click events.
 * @see TextView#getCompoundDrawables()
 * @see TextView#setCompoundDrawablesRelativeWithIntrinsicBounds(int, int, int, int)
 * @see CompoundDrawableTouchListener
 */
public abstract class CompoundDrawableClickListener extends CompoundDrawableTouchListener {

    /**
     * Default constructor
     */
    public CompoundDrawableClickListener() {
        super();
    }

     /**
     * Constructor with fuzz
     * @param fuzz desired fuzz in px
     */
    public CompoundDrawableClickListener(int fuzz) {
        super(fuzz);
    }

    @Override
    protected void onDrawableTouch(View v, int drawableIndex, Rect drawableBounds, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_UP) onDrawableClick(v, drawableIndex);
        return true;
    }

    /**
     * Compound drawable touch-event handler
     * @param v wrapping view
     * @param drawableIndex index of compound drawable which recicved the event
     */
    protected abstract void onDrawableClick(View v, int drawableIndex);
}

同样，我们可以很容易地处理点击任何复合drawable的任何TextView:

textView1.setOnTouchListener(new CompoundDrawableClickListener() {
            @Override
            protected void onDrawableClick(View v, int drawableIndex) {
                switch(v.getId()) {
                    case R.id.textView1:
                        switch(drawableIndex) {
                            case CompoundDrawableTouchListener.RIGHT:
                                doStuff();
                                break;
                        }
                        break;
                }
            }
        });

希望你和我一样喜欢。如果有任何变化，我会尽量在这里和相关的要点上保持更新。

我知道这很老了，但我最近不得不做一些类似的事情……在看到这有多难之后，我想到了一个更简单的解决方案:

创建一个包含EditText和Image的XML布局 子类framayout并扩展XML布局 为单击侦听器和任何其他您想要的行为添加代码

在我的例子中，我需要一个能够用按钮清除文本的EditText。我希望它看起来像SearchView，但由于一些原因，我不想使用这个类。下面的例子展示了我是如何完成这个任务的。尽管它与焦点变化无关，但原则是相同的，我认为发布实际的工作代码比将一个可能不完全按照我的意图工作的示例放在一起更有益:

下面是我的布局:clearle_edit_text .xml

<merge
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <EditText
        android:id="@+id/edit_text_field"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

    <!-- NOTE: Visibility cannot be set to "gone" or the padding won't get set properly in code -->
    <ImageButton
        android:id="@+id/edit_text_clear"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="right|center_vertical"
        android:background="@drawable/ic_cancel_x"
        android:visibility="invisible"/>
</merge>

这里是膨胀布局的类:clearleedittext .java

public class ClearableEditText extends FrameLayout {
    private boolean mPaddingSet = false;

    /**
     * Creates a new instance of this class.
     * @param context The context used to create the instance
     */
    public ClearableEditText (final Context context) {
        this(context, null, 0);
    }

    /**
     * Creates a new instance of this class.
     * @param context The context used to create the instance
     * @param attrs The attribute set used to customize this instance
     */
    public ClearableEditText (final Context context, final AttributeSet attrs) {
        this(context, attrs, 0);
    }

    /**
     * Creates a new instance of this class.
     * @param context The context used to create the instance
     * @param attrs The attribute set used to customize this instance
     * @param defStyle The default style to be applied to this instance
     */
    public ClearableEditText (final Context context, final AttributeSet attrs, final int defStyle) {
        super(context, attrs, defStyle);

        final LayoutInflater inflater = LayoutInflater.from(context);
        inflater.inflate(R.layout.clearable_edit_text, this, true);
    }

    @Override
    protected void onFinishInflate () {
        super.onFinishInflate();

        final EditText editField = (EditText) findViewById(R.id.edit_text_field);
        final ImageButton clearButton = (ImageButton) findViewById(R.id.edit_text_clear);

        //Set text listener so we can show/hide the close button based on whether or not it has text
        editField.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged (final CharSequence charSequence, final int i, final int i2, final int i3) {
                //Do nothing here
            }

            @Override
            public void onTextChanged (final CharSequence charSequence, final int i, final int i2, final int i3) {
                //Do nothing here
            }

            @Override
            public void afterTextChanged (final Editable editable) {
                clearButton.setVisibility(editable.length() > 0 ? View.VISIBLE : View.INVISIBLE);
            }
        });

        //Set the click listener for the button to clear the text. The act of clearing the text will hide this button because of the
        //text listener
        clearButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick (final View view) {
                editField.setText("");
            }
        });
    }

    @Override
    protected void onLayout (final boolean changed, final int left, final int top, final int right, final int bottom) {
        super.onLayout(changed, left, top, right, bottom);

        //Set padding here in the code so the text doesn't run into the close button. This could be done in the XML layout, but then if
        //the size of the image changes then we constantly need to tweak the padding when the image changes. This way it happens automatically
        if (!mPaddingSet) {
            final EditText editField = (EditText) findViewById(R.id.edit_text_field);
            final ImageButton clearButton = (ImageButton) findViewById(R.id.edit_text_clear);

            editField.setPadding(editField.getPaddingLeft(), editField.getPaddingTop(), clearButton.getWidth(), editField.getPaddingBottom());
            mPaddingSet = true;
        }
    }
}

为了使这个答案更符合问题，应该采取以下步骤:

将可绘制资源更改为您想要的任何资源…在我的情况下，它是一个灰色的X 添加一个焦点更改监听器到编辑文本…

这很简单。 假设你在你的编辑文本'txtsearch'的左边有一个可绘制的图形。 跟着做就行了。

EditText txtsearch = (EditText) findViewById(R.id.txtsearch);
txtsearch.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if(event.getAction() == MotionEvent.ACTION_UP) {
            if(event.getRawX() <= txtsearch.getTotalPaddingLeft()) {
                // your action for drawable click event

             return true;
            }
        }
        return false;
    }
});

如果你想要右绘图，将If语句更改为:

if(event.getRawX() >= txtsearch.getRight() - txtsearch.getTotalPaddingRight())

类似地，您可以为所有复合提款执行此操作。

txtsearch.getTotalPaddingTop()
txtsearch.getTotalPaddingBottom()

此方法调用返回该边的所有填充，包括任何可绘制对象。你可以使用这甚至为TextView，按钮等。
