Clicking spinner within popup window causes WindowManager$BadTokenException

Question

I\'ve looked up a couple of posts for the same problem but can\'t seem to resolve my issue. I\'ve used spinners throughout my application and they are working fine. It\'s wh

Answer 1

The following is how the popup code is being called. I've declared the variable for the PopupWindow and ViewGroup so it can be used throughout the class

private PopupWindow pw_references;
private vg_references;

The code that calls the PopupWindow is called within an event handler for a button.

public void ibtn_references_Click(View view) {
    ...
    // 1st section of code in the original post
}

This button is inside a linearlayout (seperate layout file) that is then included within a framelayout on the current screen. Included something like the following.

 <FrameLayout
    android:id="@+id/lay_rowButtons"
    android:layout_gravity="center"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"        
    android:background="@drawable/backgroud_border"
    android:padding="10dp" >

    <include android:id="@+id/buttons" layout="@layout/buttons" />

</FrameLayout>

Answer 2

Can you try by replacing following line:

pw_references = new PopupWindow(vg_references, 
    this.getWindowManager().getDefaultDisplay().getWidth()/100 * 75,
    this.getWindowManager().getDefaultDisplay().getHeight()/100 * 50,
    true);

with

pw_references = new PopupWindow(this);
pw_references.setWidth(this.getWindowManager().getDefaultDisplay().getWidth()/100 * 75);
pw_references.setHeight(this.getWindowManager().getDefaultDisplay().getHeight()/100 * 50);
pw_references.setContentView(vg_references);

where this refer to the current activity reference. Just to see if this make any difference...

Answer 3

The only way I could get this to work was to use a Dialog rather than a PopupWindow. It works fine that way

Answer 4

I had this problem in my work, and wasted about 2 days trying to find a solution to it. But, I didn't find a solution from the web.

The solution was to specify the Spinner mode to be dialog.

from XML layout:

android:spinnerMode="dialog"

or from java code:

Spinner(Context context, int mode)
