Create Portrait GoogleTV Application

Question

I'm having a tough time forcing my app to use portrait mode on Google TV. I know this is technically unsupported but I feel like I should be able to do this manually somehow, especially seeing as some apps on Google Play successfully force this behavior system wide (like: https://play.google.com/store/apps/details?id=com.coinsoft.android.orientcontrol and https://play.google.com/store/apps/details?id=nl.fameit.rotate&hl=en).

In my activity I am doing:

public void onStart() {
    View root = findViewById(android.R.id.content);     
    Animator anim = AnimatorInflater.loadAnimator(this, R.anim.rotate_90);                  
    anim.setTarget(root);
    anim.start();
}

My rotate_90.xml:

<?xml version="1.0" encoding="utf-8"?>
<objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="0"
    android:propertyName="rotation"
    android:repeatCount="0"
    android:valueTo="90"
    android:valueType="floatType" />

This seems to work, but of course doesn't do exactly what I want. The view is rotated, but all the items on the far left are now off screen. Is there a way to dynamically re-size the root layout to fit the screen in portrait mode?

Answer 1

Of course right after posting I came up with something that seems to work:

    View root = findViewById(android.R.id.content);


    DisplayMetrics displaymetrics = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
    int height = displaymetrics.heightPixels;
    int width = displaymetrics.widthPixels;

    root.getLayoutParams().height = width;
    root.getLayoutParams().width = height;
    root.requestLayout();

    root.setPivotX(height);
    root.setPivotY(height);

    Animator anim = AnimatorInflater.loadAnimator(this, R.anim.rotate_90);      
    anim.setTarget(root);
    anim.start();

Any better answers would be appreciated, but I don't see any downsides to this off the top of my head.
