Is there a simple example of the PopupWindow class using Android v2.0?

I looked online and was not able to find a working example of the PopupWindow class. The code examples I found online either compile but do not work, or are using methods which have since been removed (such as Activity.getView开发者_开发百科Inflate()).

Is there a simple working example that displays a PopupWindow?

I created a working example based on this Google Groups post.

To create a simple working PopupWindow, you'll need to do the following:

1. Create a layout XML which describes the View that will be rendered within the PopupWindow.
2. 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
