我创建了一个简单的自定义触摸侦听器类，而不是自定义EditText

public class MyTouchListener implements View.OnTouchListener {
private EditText editText;

public MyTouchListener(EditText editText) {
    this.editText = editText;

    setupDrawable(this.editText);
}

private void setupDrawable(final EditText editText) {
    editText.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            if(s.length()>0)
                editText.setCompoundDrawablesWithIntrinsicBounds(0,0, R.drawable.clearicon,0);
            else
                editText.setCompoundDrawablesWithIntrinsicBounds(0,0, 0,0);

        }

        @Override
        public void afterTextChanged(Editable s) {

        }
    });
}

@Override
public boolean onTouch(View v, MotionEvent event) {
    if(event.getAction() == MotionEvent.ACTION_UP) {
        if(editText.getCompoundDrawables()[2]!=null){
            if(event.getX() >= (editText.getRight()- editText.getLeft() - editText.getCompoundDrawables()[2].getBounds().width())) {
                editText.setText("");
            }
        }
    }
    return false;

}

}

当EditText为空白时，将没有可绘制对象。绘图将显示我们开始编辑以清除EditText的时间。

你可以设置触摸监听器

mEditText.setOnTouchListener（new MyTouchListener（mEditText））;

最好在编辑文本的右边有ImageButton，并给负布局边距与编辑文本重叠。在ImageButton上设置监听器并执行操作。

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。

我在Mono中实现了@aristo_sh answer。Droid (Xamarin)因为它是一个委托匿名方法你不能返回true或false你必须取e。event。handled。我还隐藏了点击键盘

editText.Touch += (sender, e) => {
                    e.Handled = false;
                    if (e.Event.Action == MotionEventActions.Up)
                    {
                        if (e.Event.RawX >= (bibEditText.Right - (bibEditText.GetCompoundDrawables()[2]).Bounds.Width()))
                        {
                            SearchRunner();
                            InputMethodManager manager = (InputMethodManager)GetSystemService(InputMethodService);
                            manager.HideSoftInputFromWindow(editText.WindowToken, 0);
                            e.Handled = true;
                        }
                    }
                };

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())) 

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…
