Is there a simple example of the PopupWindow class using Android v2.0?
I created a working example based on this Google Groups post.
To create a simple working PopupWindow, you'll need to do the following:
- Create a layout XML which describes the View that will be rendered within the PopupWindow.
- Invoke the PopupWindow by inflating the layout XML, and assign the appropriate "parent view" to the pop-up.
popup_example.xml:
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:padding="10dip" android:layout_width="fill_parent" android:layout_height="wrap_content" > <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginTop="10dip" android:text="Test Pop-Up" /></LinearLayout>
Java code:
LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE); PopupWindow pw = new PopupWindow( inflater.inflate(R.layout.popup_example, null, false), 100, 100, true); // The code below assumes that the root container has an id called 'main' pw.showAtLocation(this.findViewById(R.id.main), Gravity.CENTER, 0, 0);
AFAIK only the AbsoluteLayout works(pls confirm), as seen on http://sree.cc/google/android/android-popup-window . I've shown the popup right, but LinearLayout was not showing all elements. But AbsoluteLayout is deprecated!
FrameLayout also works, but organizing views is a nightmare since the official documentation says it is only good for holding one view.
Also, to be able to receive touch events, you need to do this: setBackgroundDrawable(new BitmapDrawable());
as further explained at Android popup window dismissal
You are getting the invisibility because you didn't set the Background color of the layout to whom you are inflated.set it as android:background="#778899",and definitely you can see the things
