可绘制是非互动元素，让你cannont设置的点击监听器上绘制。
一个简单的解决办法是把一个的ImageView包含搜索在图标的的EditText 并添加上一个右填充的EditText ，使文本不与图标重叠。

Drawables are non-interactive elements, so you cannont set a click listener on a drawable. A simple solution would be putting an ImageView containing the "search" icon over the EditText and adding a right padding on the EditText so the text doesn't overlap with the icon.

<FrameLayout android:layout_width="wrap_content"
             android:layout_height="wrap_content">
    <EditText ...
              android:paddingRight="..."
              ... />
    <ImageView ...
               android:src="@drawable/search"
               android:layout_gravity="right|center_vertical"
               ... />
</FrameLayout>
