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?

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;
}
});
}
其他回答
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);
}
final TextView mTvTitle = (TextView)findViewById(R.id.tvTitle1);
mTvTitle.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() <= (mTvTitle.getCompoundDrawables()[DRAWABLE_LEFT].getBounds().width())) {
// your action here
Intent intent = new Intent(DeAddExpences.this,DeHomeActivity.class);
startActivity(intent);
return true;
}
}
return true;
}
});
我想这是一个很好的方法，由Hardik4560推荐，

@Override
public boolean onTouch(View v, MotionEvent event) {
Drawable drawableObj = getResources().getDrawable(R.drawable.search_btn);
int drawableWidth = drawableObj.getIntrinsicWidth();
int x = (int) event.getX();
int y = (int) event.getY();
if (event != null && event.getAction() == MotionEvent.ACTION_UP) {
if (x >= (searchPanel_search.getWidth() - drawableWidth - searchPanel_search.getPaddingRight())
&& x <= (searchPanel_search.getWidth() - searchPanel_search.getPaddingRight())
&& y >= searchPanel_search.getPaddingTop() && y <= (searchPanel_search.getHeight() - searchPanel_search.getPaddingBottom())) {
getSearchData();
}
else {
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(searchPanel_search, InputMethodManager.SHOW_FORCED);
}
}
return super.onTouchEvent(event);
}
//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;
}
});
