使用可扩展的textview缓冲区可能是一个解决方案。看看这个简短而切中要害的教程:首先，点击事件要容易得多

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
}

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;
        }
    });
}

这么多的解决方案，但没有一个适合我，当我有两个连续的领域。 这是添加清除按钮编辑文本的解决方案，在我有两个字段或一行中的一个字段的情况下为我工作。用kotlin写的!

@SuppressLint("PrivateResource")
fun <T : EditText> T.withClear(): T {
    addTextChangedListener(object : TextWatcher {
        override fun afterTextChanged(editable: Editable) {
            setCompoundDrawablesWithIntrinsicBounds(0, 0,
                    if (editable.isNotEmpty()) abc_ic_clear_material else 0, 0)
        }

        override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) = Unit
        override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) = Unit
    })

    setOnTouchListener { _, event ->
        if (event.action == ACTION_UP && event.x >= (right - this.compoundPaddingRight)) {
            setText("")
            return@setOnTouchListener true
        }
        false
    }
    return this
}

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);

}
