Android : Issue in back from a pop up window

Question

I've used following code to create a pie chart in a pop up window in a fragment.

mChartView = ChartFactory.getPieChartView(getActivity(), distributionSeries, defaultRenderer);
    popupWindow = new PopupWindow(mChartView, LayoutParams.FILL_PARENT,  
                                 LayoutParams.FILL_PARENT, false);
                        popupWindow.setOutsideTouchable(true);
                        popupWindow.showAsDropDown(mChartView, 50, 50);
                        popupWindow.setTouchInterceptor(new OnTouchListener() {

                            @Override
                            public boolean onTouch(View v, MotionEvent event) {
                                // TODO Auto-generated method stub
                                if (event.getAction() == MotionEvent.ACTION_OUTSIDE) {
                                    popupWindow.dismiss();

                                }
                                return false;
                            }
                        });

This is my full code.

This is my new code.

private static boolean isChart = false;

popupWindow = new PopupWindow(mChartView, LayoutParams.MATCH_PARENT,  
                                LayoutParams.MATCH_PARENT, false);
                        popupWindow.setOutsideTouchable(true);
                        popupWindow.showAsDropDown(mChartView, 50, 50);
                        isChart = true;

@Override
public void onBackPressed() {
    System.out.println("BACKED");
    if(isChart) {
         popupWindow.dismiss();  
    } else {  
         super.onBackPressed();
    }
    //return;
}

It shows the chart. But it does not back from pie chart window when I press the back button in android. How can i solve this issue ? Any suggestions are highly appreciated.

Thanx in advance

Answer 1

You need to add this:

popupWindow.setBackgroundDrawable(new BitmapDrawable());

while creating your popup window, otherwise it will not react to any touch events because of background drawable being not set.

Answer 2

Your activity should override

@Override
   public void onBackPressed() {
}

Within that you should check whether the popup is visible , If so you should dismiss it

define bool _isVisible = false; // in class level bool _isVisible = false; // in class level Set _isVisible = true; // on popup.show _isVisible = true; // on popup.show

within onbackpressed()

    if(_isVisible)
        popup.dismiss();


@Override
public void onBackPressed() {
if(popupWindow != null) // dont check this if, put a bool value instead of this
{
     popupWindow.dismiss();  
} else {  
     super.onBackPressed();
}

}
