我已经在EditText小部件中添加了文本右侧的图像,使用以下XML:

<EditText
  android:id="@+id/txtsearch"
  ...
  android:layout_gravity="center_vertical"
  android:background="@layout/shape"
  android:hint="Enter place,city,state"
  android:drawableRight="@drawable/cross" />

但我想在单击嵌入图像时清除EditText。我该怎么做呢?

我想建议一种方法绘制左侧! 我尝试了这个代码,并工作。

txtsearch.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View view, MotionEvent event) {
            final int DRAWABLE_LEFT = 0;
            int start=txtsearch.getSelectionStart();
            int end=txtsearch.getSelectionEnd();
            if(event.getAction() == MotionEvent.ACTION_UP) {
                if(event.getRawX() <= (txtsearch.getLeft() + txtsearch.getCompoundDrawables()[DRAWABLE_LEFT].getBounds().width())) {
                    //Do your action here
                    return true;
                }

            }
            return false;
        }
    });
}

其他回答

按照下面的代码绘制右,左,上,下点击:

edittextview_confirmpassword.setOnTouchListener(new View.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() >= (edittextview_confirmpassword.getRight() - edittextview_confirmpassword.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
                // your action here                    edittextview_confirmpassword.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);
                return true;
            }
        }else{
            edittextview_confirmpassword.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);

        }
        return false;
    }
});

}

对于任何不想实现可怕的点击处理的人。你可以用RelativeLayout实现同样的效果。有了它,你甚至可以自由处理可绘制对象的定位。

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

   <android.support.design.widget.TextInputLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content">

     <android.support.design.widget.TextInputEditText
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
      />
     </android.support.design.widget.TextInputLayout>
     <ImageView
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_alignParentEnd="true"
       android:layout_centerInParent="true"
       android:src="@drawable/ic_undo"/>
    </RelativeLayout>

ImageView的位置将与你使用drawableEnd相同-加上你不需要所有的触摸监听器处理。只需要点击ImageView的监听器就可以了。

用于左侧可绘制的单击侦听器

txt.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            final int DRAWABLE_LEFT = 0;

            if (event.getAction() == MotionEvent.ACTION_UP) {
                if (event.getRawX() <= (txt
                        .getCompoundDrawables()[DRAWABLE_LEFT].getBounds().width() +
                        txt.getPaddingLeft() +
                        txt.getLeft())) {

                          //TODO do code here
                    }
                    return true;
                }
            }
            return false;
        }
    });

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

非常非常好,感谢所有参与讨论的人。因此,如果你不想处理扩展类带来的不便,你可以执行以下操作(仅为正确的可绘制对象实现)

this.keyword = (AutoCompleteTextView) findViewById(R.id.search);
this.keyword.setOnTouchListener(new RightDrawableOnTouchListener(keyword) {
        @Override
        public boolean onDrawableTouch(final MotionEvent event) {
            return onClickSearch(keyword,event);
        }
    });

private boolean onClickSearch(final View view, MotionEvent event) {
    // do something
    event.setAction(MotionEvent.ACTION_CANCEL);
    return false;
}

下面是基于@Mark的回答的基本侦听器实现

public abstract class RightDrawableOnTouchListener implements OnTouchListener {
    Drawable drawable;
    private int fuzz = 10;

    /**
     * @param keyword
     */
    public RightDrawableOnTouchListener(TextView view) {
        super();
        final Drawable[] drawables = view.getCompoundDrawables();
        if (drawables != null && drawables.length == 4)
            this.drawable = drawables[2];
    }

    /*
     * (non-Javadoc)
     * 
     * @see android.view.View.OnTouchListener#onTouch(android.view.View, android.view.MotionEvent)
     */
    @Override
    public boolean onTouch(final View v, final MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_DOWN && drawable != null) {
            final int x = (int) event.getX();
            final int y = (int) event.getY();
            final Rect bounds = drawable.getBounds();
            if (x >= (v.getRight() - bounds.width() - fuzz) && x <= (v.getRight() - v.getPaddingRight() + fuzz)
                    && y >= (v.getPaddingTop() - fuzz) && y <= (v.getHeight() - v.getPaddingBottom()) + fuzz) {
                return onDrawableTouch(event);
            }
        }
        return false;
    }

    public abstract boolean onDrawableTouch(final MotionEvent event);

}
