PopupWindow - Dismiss when clicked outside

问题

I have a PopupWindow on my activity, the thing is my PopupWindow still shows even when I\'m interacting with my activity (say scrolling on my list). I can scroll through my list and the PopupWindow is still there.

What I want to achieve is when I\'m touching/scrolling/clicking/etc on the screen which is not the PopupWindow, I want to dismiss the PopupWindow. Just like how a menu works. If you clicked outside of the menu, the menu will be dismissed.

I\'ve tried setOutsideTouchable(true) but it won\'t dismiss the window. Thanks.

回答1:

Please try to set setBackgroundDrawable on PopupWindow that should close the window if you touch outside of it.

I found that none of the answers supplied worked for me, except WareNinja's comment on the accepted answer, and Marcin S.'s will probably also work. Here's the part that works for me:

myPopupWindow.setBackgroundDrawable(new BitmapDrawable());
myPopupWindow.setOutsideTouchable(true);

Alternatively:

myPopupWindow.setFocusable(true);

Not sure what the differences are, but the ListPopupWindow source code actually uses the latter when it's modality is set to true with setModal, so at least the Android developers consider this a viable approach, and it's only one line.

I met the same issues, and fixed it as below codes. It works fine for me.

    // Closes the popup window when touch outside.
    mPopupWindow.setOutsideTouchable(true);
    mPopupWindow.setFocusable(true);
    // Removes default background.
    mPopupWindow.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

BTW, Don't use BitmapDrawable deprecated constructor, use this new ColorDrawable(android.R.color.transparent) to replace default background.

Have fun@.@

I know it's late but I notice that people still have an issue with the popup window. I have decided to write a fully working example where you can dismiss the popup window by touching or clicking outside of it or just touching the window itself. To do so create a new PopupWindow class and copy this code:

PopupWindow.class

public class PopupWindow extends android.widget.PopupWindow
{
Context ctx;
Button btnDismiss;
TextView lblText;
View popupView;

public PopupWindow(Context context)
{
    super(context);

    ctx = context;
    popupView = LayoutInflater.from(context).inflate(R.layout.popup, null);
    setContentView(popupView);

    btnDismiss = (Button)popupView.findViewById(R.id.btn_dismiss);
    lblText = (TextView)popupView.findViewById(R.id.text);

    setHeight(WindowManager.LayoutParams.WRAP_CONTENT);
    setWidth(WindowManager.LayoutParams.WRAP_CONTENT);

    // Closes the popup window when touch outside of it - when looses focus
    setOutsideTouchable(true);
    setFocusable(true);

    // Removes default black background
    setBackgroundDrawable(new BitmapDrawable());

    btnDismiss.setOnClickListener(new Button.OnClickListener(){

        @Override
        public void onClick(View v) {


         dismiss();
        }});

    // Closes the popup window when touch it
/*     this.setTouchInterceptor(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {

            if (event.getAction() == MotionEvent.ACTION_MOVE) {
                dismiss();
            }
            return true;
        }
    }); */   
   } // End constructor

   // Attaches the view to its parent anchor-view at position x and y
   public void show(View anchor, int x, int y)
   {
      showAtLocation(anchor, Gravity.CENTER, x, y);
   }
}

Now create the layout for the popup window: popup.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout     
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="1dp"
    android:orientation="vertical"
    android:padding="10dp" >

<TextView 
    android:id="@+id/text" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"  
    android:gravity="center" 
    android:padding="5dp" 
    android:text="PopupWindow Example"
    android:textColor="#000000" 
    android:textSize="17sp" 
    android:textStyle="italic" />

<FrameLayout
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_gravity="center_vertical">

    <Button
        android:id="@+id/btn_dismiss" 
        style="?android:attr/buttonStyleSmall" 
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content" 
        android:text="Dismiss" 
        android:visibility="gone" />

    <TextView
        android:id="@+id/lbl_dismiss"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:text="Touch outside of this box to dismiss"
        android:textColor="#ffffff"
        android:textStyle="bold" />

</FrameLayout>      

In your main activity create an instance of the PopupWindow class:

final PopupWindow popupWindow = new PopupWindow(this);
popupWindow.show(findViewById(R.id.YOUR_MAIN_LAYOUT), 0, -250);

where YOUR_MAIN_LAYOUT is the layout of the current activity in which popupWindow will pop up

回答5:

Thanks for @LunaKong's answer and @HourGlass's confirmation. I don't want to make a duplicated comment, but only want to make it clear and concise.

// Closes the popup window when touch outside. This method was written informatively in Google's docs.
mPopupWindow.setOutsideTouchable(true);

// Set focus true to prevent a touch event to go to a below view (main layout), which works like a dialog with 'cancel' property => Try it! And you will know what I mean.
mPopupWindow.setFocusable(true);

// Removes default background.
mPopupWindow.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

Mttdat.

回答6:

For a ListPopupWindow set the window to be a modal when shown.

mListPopupWindow.setModal(true);

That way, clicking outside of the ListPopupWindow will dismiss it.

回答7:

Notice that for canceling with popupWindow.setOutsideTouchable(true), you need to make width and height wrap_content like below code:

PopupWindow popupWindow = new PopupWindow(
            G.layoutInflater.inflate(R.layout.lay_dialog_support, null, false),
            WindowManager.LayoutParams.WRAP_CONTENT,
            WindowManager.LayoutParams.WRAP_CONTENT, true);

popupWindow.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
popupWindow.setOutsideTouchable(true);
popupWindow.setFocusable(true);
popupWindow.showAtLocation(view, Gravity.RIGHT, 0, 0);

回答8:

mPopWindow.setFocusable(true);

回答9:

Set the window background transparent:

PopupWindow.getBackground().setAlpha(0);

After it set your background in layout. Works fine.

回答10:

@LunaKong suggestion work's like a charm.

But setting up mPopupWindow.setFocusable(false). removes unnecessary touch required to make popup window disappear.

For example: Let's consider there is a pop up window visible on screen, and you are about to click a button. So in this case, (if mpopwindow.setFocusable(true)) on the first click of a button popupwindow will dismiss. But you have to click again to make the button works. if**(mpopwindwo.setFocusable(false)** single click of button dismiss the popup window as well as trigger the button click. Hope it helps.

回答11:

  popupWindow.setTouchable(true);
  popupWindow.setFocusable(true);
  popupWindow.showAtLocation(popupView, Gravity.CENTER, 0, 0);

It will dismiss the PopupWindow when click/touch on screen.Make sure you have set focusable true before showAtLocation.

回答12:

In some cases making the popup focusable is not desirable (e.g. you may not want it to steal focus from another view).

An alternative approach is using a touch interceptor:

popupWindow.setOutsideTouchable(true);
popupWindow.setTouchInterceptor(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_OUTSIDE) {
            popupWindow.dismiss();
        }
        return false;
    }
});

回答13:

Use View popupView to dismiss the popupWindow

`popupView.setOnClickListener(new View.OnClickListener() {
                   @Override
                   public void onClick(View view) {
                       popupWindow.dismiss();
                   }
               }); 

` If you use this you can also setOnClickListener to any button inside the popupWindow

回答14:

You can use isOutsideTouchable OR isFocusable to dissmiss popup window when touch outside

popupWindow.isOutsideTouchable = true // dismiss popupwindow when touch outside

popupWindow.isFocusable = true // dismiss popupwindow when touch outside AND when press back button

Note

• Currently, after test I see setBackgroundDrawable don't help us dismiss popupwindow

• If you look at the code for dismiss in PopupWindow (PopupWindow->PopupDecorView->dispatchKeyEvent and PopupWindow->PopupDecorView->onTouchEvent). You will see that when press back button, they dismiss on ACTION_UP and when touch outside they dismiss on ACTION_UP or ACTION_OUTSIDE
