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
