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。

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。

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;
                }
            });

我是这样做的

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

                <android.support.design.widget.TextInputLayout
                    android:id="@+id/til_text"

                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:layout_alignParentTop="true"
                    android:textColorHint="@color/colorSilver">

                    <android.support.design.widget.TextInputEditText
                        android:id="@+id/tiet_text"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:gravity="top|left"
                        android:hint="@string/rep_hint"
                        android:inputType="textMultiLine"
                        android:maxLines="3"
                        android:drawableEnd="@drawable/ic_attach_photo"
                        android:drawablePadding="5dp"
                        android:textColor="@color/colorPrimaryText"
                        android:textColorHint="@color/colorSilver"
                      />

                </android.support.design.widget.TextInputLayout>

                <View
                    android:id="@+id/right_button"
                    android:layout_width="24dp"
                    android:layout_height="24dp"
                    android:layout_centerVertical="true"
                    android:layout_alignParentEnd="true"
                    android:layout_marginEnd="12dp"
                    android:background="@color/clear" />
            </RelativeLayout>

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)。

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。
