How to add relative layout to relative layout with slide in effect?

Question

I have a relative layout in which i add a second relative layout which contains 4 buttons. when i do: relativeLayout1.addView(relativeLayout2,params) i want that the added relative layout with the 4 buttons slides in from right to left.

Is that somehow possible?

xml:

<translate xmlns:android="http://schemas.android.com/apk/res/android" android:duration="500" android:fromXDelta="100%" android:toXDelta="0%" > </translate>

code: ```

public Panel(Context context) {
    super(context);

    this.setBackgroundColor(Color.BLACK);
    this.setId(R.id.panel);

    right_menubar = new RelativeLayout(context);
    right_menubar.setId(R.id.panel_indicators);

    plp_right_menu_bar = new RelativeLayout.LayoutParams(100, 100);

    this.addView(right_menubar, plp_right_menu_bar);

    Animation fadeIn = AnimationUtils.loadAnimation(context, R.animator.anim);
    right_menubar.startAnimation(fadeIn);

}

Answer 1

instead of 100% and 0% use 100%p and 0%p

%p signifies percentage of its parent. i think that is what you are trying to do.

Answer 2

It is working now,

right_menubar.setId(R.id.panel_indicators);
plp_right_menu_bar = new RelativeLayout.LayoutParams(100, 100);
plp_right_menu_bar.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
this.addView(right_menubar, plp_right_menu_bar);
right_menubar.startAnimation(AnimationUtils.loadAnimation(this.getContext(), R.animator.anim));

No need to set it to invisible before the animation.
