上述解决方案有效，但也有副作用。如果你有一个EditText和右drawable

你会得到一个粘贴按钮后，每次点击绘制。查看如何禁用粘贴在onClickListener的可绘制权的编辑文本Android(在图标EditText)。

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())) 

考虑以下几点。这不是最优雅的解决方案，但它是有效的，我刚刚测试过。

Create a customized EditText class CustomEditText.java: import android.content.Context; import android.graphics.Rect; import android.graphics.drawable.Drawable; import android.util.AttributeSet; import android.view.MotionEvent; import android.widget.EditText; public class CustomEditText extends EditText { private Drawable dRight; private Rect rBounds; public CustomEditText(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } public CustomEditText(Context context, AttributeSet attrs) { super(context, attrs); } public CustomEditText(Context context) { super(context); } @Override public void setCompoundDrawables(Drawable left, Drawable top, Drawable right, Drawable bottom) { if(right !=null) { dRight = right; } super.setCompoundDrawables(left, top, right, bottom); } @Override public boolean onTouchEvent(MotionEvent event) { if(event.getAction() == MotionEvent.ACTION_UP && dRight!=null) { rBounds = dRight.getBounds(); final int x = (int)event.getX(); final int y = (int)event.getY(); //System.out.println("x:/y: "+x+"/"+y); //System.out.println("bounds: "+bounds.left+"/"+bounds.right+"/"+bounds.top+"/"+bounds.bottom); //check to make sure the touch event was within the bounds of the drawable if(x>=(this.getRight()-rBounds.width()) && x<=(this.getRight()-this.getPaddingRight()) && y>=this.getPaddingTop() && y<=(this.getHeight()-this.getPaddingBottom())) { //System.out.println("touch"); this.setText(""); event.setAction(MotionEvent.ACTION_CANCEL);//use this to prevent the keyboard from coming up } } return super.onTouchEvent(event); } @Override protected void finalize() throws Throwable { dRight = null; rBounds = null; super.finalize(); } } Change your layout XML to this (where com.example is your actual project package name): <com.example.CustomEditText android:id="@+id/txtsearch" … android:layout_gravity="center_vertical" android:background="@layout/shape" android:hint="Enter place,city,state" android:drawableRight="@drawable/cross" /> Finally, add this (or something similar) to your activity: … CustomEditText et = (CustomEditText) this.findViewById(R.id.txtsearch); …

我可能在计算嵌套drawable的触摸边界时有点出错，但你懂的。

我希望这能有所帮助。

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。

这是我的简单解决方案，只是把ImageButton放在EditText上:

<RelativeLayout
  android:layout_width="match_parent"
  android:layout_height="wrap_content">

  <EditText android:id="@+id/editTextName"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:imeOptions="actionSearch"
    android:inputType="text"/>

  <ImageButton android:id="@+id/imageViewSearch"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_action_search"
    android:layout_alignParentRight="true"
    android:layout_centerVertical="true"/>

</RelativeLayout>

扩展了RyanM的想法，我创建了一个更灵活的版本，它支持所有可绘制的类型(上、下、左、右)。虽然下面的代码扩展了TextView，适应它的编辑文本只是交换“扩展TextView”与“扩展EditText”的情况。从XML实例化小部件与在RyanM的示例中相同，只是小部件名称不同。

import android.content.Context;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.util.Log;
import android.view.MotionEvent;
import android.widget.TextView;

import com.example.DrawableClickListener.DrawablePosition;

public class ButtonTextView extends TextView {

private Drawable    drawableRight;
private Drawable    drawableLeft;
private Drawable    drawableTop;
private Drawable    drawableBottom;

private int     actionX, actionY;

private DrawableClickListener clickListener;

public ButtonTextView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
}

public ButtonTextView(Context context, AttributeSet attrs) {
    super(context, attrs);
}

public ButtonTextView(Context context) {
    super(context);
}

@Override
public void setCompoundDrawables(Drawable left, Drawable top, Drawable right, Drawable bottom) {
    if (right != null) {
        drawableRight = right;
    }

    if (left != null) {
        drawableLeft = left;
    }

    if (top != null) {
        drawableTop = top;
    }

    if (bottom != null) {
        drawableBottom = bottom;
    }

    super.setCompoundDrawables(left, top, right, bottom);
}

@Override
public boolean onTouchEvent(MotionEvent event) {

    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        actionX = (int) event.getX();
        actionY = (int) event.getY();

        if (drawableBottom != null && drawableBottom.getBounds().contains(actionX, actionY)) {
            clickListener.onClick(DrawablePosition.BOTTOM);
            return super.onTouchEvent(event);
        }

        if (drawableTop != null && drawableTop.getBounds().contains(actionX, actionY)) {
            clickListener.onClick(DrawablePosition.TOP);
            return super.onTouchEvent(event);
        }

        if (drawableLeft != null && drawableLeft.getBounds().contains(actionX, actionY)) {
            clickListener.onClick(DrawablePosition.LEFT);
            return super.onTouchEvent(event);
        }

        if (drawableRight != null && drawableRight.getBounds().contains(actionX, actionY)) {
            clickListener.onClick(DrawablePosition.RIGHT);
            return super.onTouchEvent(event);
        }
    }


    return super.onTouchEvent(event);
}

@Override
protected void finalize() throws Throwable {
    drawableRight = null;
    drawableBottom = null;
    drawableLeft = null;
    drawableTop = null;
    super.finalize();
}

public void setDrawableClickListener(DrawableClickListener listener) {
    this.clickListener = listener;
}}

DrawableClickListener就像这样简单:

public interface DrawableClickListener {

public static enum DrawablePosition { TOP, BOTTOM, LEFT, RIGHT };
public void onClick(DrawablePosition target); }

然后是实际的实现:

class example implements DrawableClickListener {
public void onClick(DrawablePosition target) {
    switch (target) {
        case LEFT:
            doSomethingA();
            break;

        case RIGHT:
            doSomethingB();
            break;

        case BOTTOM:
            doSomethingC();
            break;

        case TOP:
            doSomethingD();
            break;

        default:
            break;
    }
}}

注:如果你不设置监听器，触摸TextView将导致一个NullPointerException。您可能希望在代码中添加更多的偏执狂。
