Android – Why does AlertDialog.Builder not have setOnDismissListener or setOnShowListener methods

androidandroid-alertdialog

I want to use the fluid interface of AlertDialog.Builder but when I get to the point of adding my DismissListener and ShowListener I have to break out and add it to the dialog object after I do my create() on the builder. Does anyone know why they're not on there? I can't extend it because of the private P member… It's not the end of the world or anything, I'm just curious why it's not there.

Have You Tried this method..

AlertDialog dlg = builder.create();
lg.setOnDismissListener(new DialogInterface.OnDismissListener() {
@Override
public void onDismiss(final DialogInterface dialog) {
//Do some work
}
});
return dlg;

Android – Can’t create handler inside thread that has not called Looper.prepare()

You need to call Toast.makeText(...) from the UI thread:

activity.runOnUiThread(new Runnable() {
  public void run() {
    Toast.makeText(activity, "Hello", Toast.LENGTH_SHORT).show();
  }
});

This is copy-pasted from another (duplicate) SO answer.

Android – What does android:layout_weight mean

With layout_weight you can specify a size ratio between multiple views. E.g. you have a MapView and a table which should show some additional information to the map. The map should use 3/4 of the screen and table should use 1/4 of the screen. Then you will set the layout_weight of the map to 3 and the layout_weight of the table to 1.

To get it work you also have to set the height or width (depending on your orientation) to 0px.
