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
//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;
}
});
其他回答
这对我有用:)希望这对你也有帮助
edit_account_name.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
if (event.getRawX() >= (edit_account_name.getRight())) {
//clicked
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()))
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;
}
});
}
//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;
}
});
上述解决方案有效，但也有副作用。如果你有一个EditText和右drawable
你会得到一个粘贴按钮后，每次点击绘制。查看如何禁用粘贴在onClickListener的可绘制权的编辑文本Android(在图标EditText)。
