Auto dismiss popupWindow with AsyncTask

This example we will open PopupWindow together with a AsyncTask. Once the AsyncTask count for 10 seconds, it will dismiss the PopupWindow; to show how to dismiss PopupWindow outside itself.

/res/layout/popup.xml, the layout of the PopupWindow.

package com.example.androidpopupwindow;

public class MainActivity extends ActionBarActivity {

 LinearLayout mainLayout;

 @Override

  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  mainLayout = (LinearLayout)findViewById(R.id.mainlayout);

  progressBar = (ProgressBar) findViewById(R.id.progressbar);
  msg = (TextView)findViewById(R.id.msg);
  
  final Button btnOpenPopup = (Button) findViewById(R.id.openpopup);
  btnOpenPopup.setOnClickListener(new Button.OnClickListener() {

   @Override
   public void onClick(View arg0) {
    LayoutInflater layoutInflater = (LayoutInflater) getBaseContext()
      .getSystemService(LAYOUT_INFLATER_SERVICE);
    View popupView = layoutInflater.inflate(R.layout.popup, null);
    final PopupWindow popupWindow = new PopupWindow(popupView,
      LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

    Button btnDismiss = (Button) popupView
      .findViewById(R.id.dismiss);
    btnDismiss.setOnClickListener(new Button.OnClickListener() {

     }
    });
    
    TextView me = (TextView) popupView
      .findViewById(R.id.me);
    me.setText(popupWindow.toString());

    //Center the PopupWindow
    popupWindow.showAtLocation(mainLayout, Gravity.CENTER, 0, 0);

    //Auto dismiss PopupWindow in 10 sec
    new DismissAsyncTask(progressBar, msg, popupWindow).execute();
   }
  });
 }

 public class DismissAsyncTask extends AsyncTask<Void, Integer, Void> {

  ProgressBar taskProgressBar;
  TextView taskMsg;
  PopupWindow taskPopupWindow;

  public DismissAsyncTask(ProgressBar targetProgressBar,
    TextView targetMsg,
    PopupWindow targetPopupWindow) {
   taskProgressBar = targetProgressBar;
   taskMsg = targetMsg;
   taskProgressBar.setVisibility(View.VISIBLE);
   taskPopupWindow = targetPopupWindow;
  }

  @Override
  protected Void doInBackground(Void... params) {
   for (int i = 0; i < 10; i++) {
    publishProgress(i);
    SystemClock.sleep(1000);
   }
   return null;
  }

  @Override
  protected void onProgressUpdate(Integer... values) {
   taskProgressBar.setVisibility(View.VISIBLE);
   taskProgressBar.setProgress(values[0]);
   
   taskMsg.setText("Updated by : " 
    + taskPopupWindow.toString() 
    + " - " + values[0]);
  }

  @Override
  protected void onPostExecute(Void result) {
   Toast.makeText(MainActivity.this, 
    "Dismiss PopupWindows: " + taskPopupWindow.toString(), 
    Toast.LENGTH_LONG).show();
   
   taskProgressBar.setVisibility(View.INVISIBLE);
   taskPopupWindow.dismiss();
  }
 }

}

  }

  @Override

    Toast.LENGTH_LONG).show();
   
   taskProgressBar.setVisibility(View.INVISIBLE);
   taskPopupWindow.dismiss();
  }
 }

}

Remark for AsyncTask:
- In this implementation, I haven't stop the AsyncTask if the PopupWindow dismissed by button. So the associated AsyncTask still run in background. I intentionally implement like this, to show the behavior of AsyncTask.
- Starting with HONEYCOMB, AsyncTask are executed on a single thread, that means one by one (read Run multi AsyncTask at the same time). If user start a PopupWindow A and AsyncTask A, and dismiss PopupWindow A with button, AsyncTask A still running. Then start PopupWindow B and AsyncTask B. It will wait AsyncTask A finished, then start AsyncTask B,...then finish, then dismiss PopupWindow B.

Example of using PopupMenu

Android 3.0(API Level 11) provide android.widget.PopupMenu class, to displays a Menu in a modal popup window anchored to a View. The popup will appear below the anchor view if there is room, or above it if there is not. If the IME is visible the popup will not overlap it until it is touched. Touching outside of the popup will dismiss it.



Create a file /res/menu/popupmenu.xml to define the PopupMenu.

<menu xmlns:android="http://schemas.android.com/apk/res/android">
  <group android:id="@+id/group_popupmenu">
      <item android:id="@+id/menu1"
          android:title="Popup menu item 1"/>
      <item android:id="@+id/menu2"
          android:title="Popup menu item 2"/>
      <item android:id="@+id/menu3"
          android:title="Popup menu item 3"/>
  </group>
</menu>
