我使用了一个简短的解决方案，甚至适用于对话的片段。

            //The listener of a drawableEnd button for clear a TextInputEditText
            textValue.setOnTouchListener(new View.OnTouchListener() {
                @Override
                public boolean onTouch(View v, MotionEvent event) {
                    if(event.getAction() == MotionEvent.ACTION_UP) {
                        final TextView textView = (TextView)v;
                        if(event.getX() >= textView.getWidth() - textView.getCompoundPaddingEnd()) {
                            textView.setText(""); //Clear a view, example: EditText or TextView
                            return true;
                        }
                    }
                    return false;
                }
            });

<FrameLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="5dp" >

            <EditText
                android:id="@+id/edt_status_text"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginBottom="10dp"
                android:background="@drawable/txt_box_blank"
                android:ems="10"
                android:hint="@string/statusnote"
                android:paddingLeft="5dp"
                android:paddingRight="10dp"
                android:textColor="@android:color/black" />

            <Button
                android:id="@+id/note_del"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="right"
                android:layout_marginRight="1dp"
                android:layout_marginTop="5dp"
                android:background="@android:drawable/ic_delete" />
        </FrameLayout>

我已经采取了@AZ_的解决方案，并将其转换为kotlin扩展函数:

所以在代码中复制这个:

@SuppressLint("ClickableViewAccessibility")
fun EditText.setDrawableRightTouch(setClickListener: () -> Unit) {
    this.setOnTouchListener(View.OnTouchListener { _, event ->
        val DRAWABLE_LEFT = 0
        val DRAWABLE_TOP = 1
        val DRAWABLE_RIGHT = 2
        val DRAWABLE_BOTTOM = 3
        if (event.action == MotionEvent.ACTION_UP) {
            if (event.rawX >= this.right - this.compoundDrawables[DRAWABLE_RIGHT].bounds.width()
            ) {
                setClickListener()
                return@OnTouchListener true
            }
        }
        false
    })
}

你可以在EditText上调用setDrawableRightTouch函数来使用它:

yourEditText.setDrawableRightTouch {
    //your code
}

这对我很有用，

mEditTextSearch.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            if(s.length()>0){
                mEditTextSearch.setCompoundDrawablesWithIntrinsicBounds(null, null, getResources().getDrawable(android.R.drawable.ic_delete), null);
            }else{
                mEditTextSearch.setCompoundDrawablesWithIntrinsicBounds(null, null, getResources().getDrawable(R.drawable.abc_ic_search), null);
            }
        }
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        }
        @Override
        public void afterTextChanged(Editable s) {
        }
    });
    mEditTextSearch.setOnTouchListener(new OnTouchListener() {
        @SuppressLint("ClickableViewAccessibility")
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if(event.getAction() == MotionEvent.ACTION_UP) {
                if(mEditTextSearch.getCompoundDrawables()[2]!=null){
                    if(event.getX() >= (mEditTextSearch.getRight()- mEditTextSearch.getLeft() - mEditTextSearch.getCompoundDrawables()[2].getBounds().width())) {
                        mEditTextSearch.setText("");
                    }
                }
            }
            return false;
        }
    });

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。

That last contribution's use of contains(x,y) won't work directly on the result of getBounds() (except, by coincidence, when using "left" drawables). The getBounds method only provides the Rect defining points of the drawable item normalized with origin at 0,0 - so, you actually need to do the math of the original post to find out if the click is in the area of the drawable in the context of the containing EditText's dimensions, but change it for top, right, left etc. Alternatively you could describe a Rect that has coordinates actually relative to its position in the EditText container and use contains(), although in the end you're doing the same math.

将它们结合在一起就可以得到一个相当完整的解决方案，我只添加了一个实例属性consumesEvent，它让API用户决定是否应该通过使用其结果设置ACTION_CANCEL来传递单击事件。

此外，我不明白为什么边界和actionX, actionony值是实例属性，而不仅仅是堆栈上的本地属性。

下面是我在上面的基础上制作的实现的剪接图。它修复了正确使用事件需要返回false的问题。它增加了一个“模糊”因素。在我使用EditText字段中的Voice控件图标的用例中，我发现很难单击，因此模糊增加了被认为是单击可绘制对象的有效边界。对我来说，15个很好。我只需要drawableRight，所以我没有把数学插入其他的，以节省一些空间，但你明白这个想法。
