    showPopupWindow();
}

/*** button control the PopupWindow ***/
private void showPopupWindow() {
    View view = View.inflate(this, R.layout.popwindow_item, null);
    popupwindow = new PopupWindow(view, WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
    if (popupwindow.isShowing()) {  
        popupwindow.dismiss();
    }else {
        popupwindow.setOutsideTouchable(true);
        popupwindow.setBackgroundDrawable(new BitmapDrawable());
        popupwindow.showAsDropDown(title);
    }
    viewOfPop(view);
}

mPopupWindow.setOutsideTouchable(true);

That makes your PopupWindow receive Touch Events outside of it including your Button.

When ACTION_DOWN happened, your PopupWindow will be dismissed.

When ACTION_UP happened, the Button was clicked, so go to showPopupWindow()

That why when you click the button, your PopupWindow will flicker and show forever.

I think you are always create a new popupwindow, try to add a checking.

private void showPopupWindow() {
    if(popupwindow == null){
        View view = View.inflate(this, R.layout.popwindow_item, null);
        popupwindow = new PopupWindow(view, WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
    } 
    if (popupwindow.isShowing()) {  
        popupwindow.dismiss();
    }else {
        popupwindow.setOutsideTouchable(true);
        popupwindow.setBackgroundDrawable(new BitmapDrawable());
        popupwindow.showAsDropDown(title);
    }
    viewOfPop(view);
}
