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?
当前回答
我创建了一个有用的抽象类DrawableClickListener实现OnTouchListener。
除了DrawableClickListener类之外，我还创建了4个额外的抽象类，它们扩展了DrawableClickListener类，并处理对正确象限的可绘制区域的单击。
LeftDrawableClickListener TopDrawableClickListener RightDrawableClickListener BottomDrawableClickListener
考虑要点
需要考虑的一件事是，如果这样做，图像不会调整大小;因此，在放入res/drawable文件夹之前，图像必须正确缩放。
如果你定义一个LinearLayout包含一个ImageView和一个TextView，这是很容易操纵图像的大小显示。

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;
}
});
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;
}
});
//单击右图标
editText.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
final int DRAWABLE_RIGHT = 2;
if(event.getAction() == MotionEvent.ACTION_UP) {
if(event.getRawX() >= (createEventBinding.etAddressLine1.getRight() - createEventBinding.etAddressLine1.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) {
// your action here
Toast.makeText(getActivity(), "Right icon click", Toast.LENGTH_SHORT).show();
return true;
}
}
return false;
}
});
