This is this the class for popover :
public class Popover extends Activity{
private PopupWindow popWindow;
LayoutInflater layoutInflater;
private Context mContext;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
// call this method when required to show popup
public void onShowPopup(View v){
layoutInflater = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// inflate the custom popup layout
final View inflatedView = layoutInflater.inflate(R.layout.fb_popup_layout, null,false);
// find the ListView in the popup layout
ListView listView = (ListView)inflatedView.findViewById(R.id.commentsListView);
// get device size
Display display = getWindowManager().getDefaultDisplay();
final Point size = new Point();
display.getSize(size);
int mDeviceHeight = size.y;
// fill the data to the list items
setSimpleList(listView);
// set height depends on the device size
popWindow = new PopupWindow(inflatedView, size.x - 50,size.y - 400, true );
// set a background drawable with rounders corners
popWindow.setBackgroundDrawable(getResources().getDrawable(R.drawable.fb_popup_bg));
// make it focusable to show the keyboard to enter in `EditText`
popWindow.setFocusable(true);
// make it outside touchable to dismiss the popup window
popWindow.setOutsideTouchable(true);
// show the popup at bottom of the screen and set some margin at bottom ie,
popWindow.showAtLocation(v, Gravity.BOTTOM, 0,100);
}
void setSimpleList(ListView listView){
ArrayList<String> contactsList = new ArrayList<String>();
for (int index = 0; index < 10; index++) {
contactsList.add("I am @ index " + index + " today " + Calendar.getInstance().getTime().toString());
}
listView.setAdapter(new ArrayAdapter<String>(Popover.this,
R.layout.fb_comments_list_item, android.R.id.text1,contactsList));
}
}
