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;
        }
    });

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())) 

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>

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;
                        }
                    }
                };

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。

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））;
