How can I get an Android TableLayout to fill the parent in landscape mode?

Question

I am using a TableLayout in my application. It contains four TableRows each containing four ImageViews. The behavior I want is to scale the layout to fit the shortest dimension.

It works fine in portrait mode but fails miserably in landscape mode.

From the documentation it looks like this is because the TableRow layout_height is always set to WRAP_CONTENT. While I can set the dimensions of the individual Views, the TableLayout won't render at all if I set the View layout_height to FILL_PARENT.

I feel like there is something simple I am missing. Is there a way to get the TableLayout with TableRows to scale to fit the height in landscape mode?

XML Layout:

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/table"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:shrinkColumns="*">
</TableLayout>

Java:

public class Example extends Activity {

private TableLayout mTable;
private int[] mDrawableIds = {  R.drawable.draw01, R.drawable.draw02, R.drawable.draw03, R.drawable.draw04, R.drawable.draw05, R.drawable.draw06,   R.drawable.draw07, R.drawable.draw08, R.drawable.draw09, R.drawable.draw10, R.drawable.draw11, R.drawable.draw12, R.drawable.draw13, R.drawable.draw14, R.drawable.draw15, R.drawable.draw16 };

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mTable = (TableLayout)findViewById(R.id.table);
    for (int j=0; j<4; j++) {
        TableRow tr = new TableRow(this);
        tr.setLayoutParams(new ViewGroup.LayoutParams(  LayoutParams.FILL_PARENT,
                LayoutParams.WRAP_CONTENT));
           for (int i=0; i<4; i++) {
               ImageView iv = new ImageView(this);
               iv.setImageResource(mDrawableIds[j*4+i]);
               iv.setScaleType(ImageView.ScaleType.FIT_CENTER);
               iv.setAdjustViewBounds(true);
               tr.addView(iv);
           }
        mTable.addView(tr);
    }
}
}

Change your XML layout to:

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/table"
        android:layout_width="fill_parent"
        android:layout_height="160dp"
        android:shrinkColumns="*">
</TableLayout>

That should make it take up whole screen's height regardless of orientation. See density independent pixels
