I solved this with a rahter ugly hack for lack of better idea:
In a derived class (which extends Switch), I overrode the following method:
@Override
public void requestLayout() {
IslLog.i(TAG, "requestLayout");
try {
java.lang.reflect.Field mOnLayout =
Switch.class.getDeclaredField("mOnLayout");
mOnLayout.setAccessible(true);
mOnLayout.set(this, null);
java.lang.reflect.Field mOffLayout =
Switch.class.getDeclaredField("mOffLayout");
mOffLayout.setAccessible(true);
mOffLayout.set(this, null);
} catch (Exception x) {
Log.e(TAG, x.getMessage(), x);
}
super.requestLayout();
}
This now works. After I use `setTextOn` or `setTextOff`, I just call
`requestLayout`, which uses reflection to set `mOnLayout` and `mOffLayout`
to null; `requestLayout` in turn triggers `onMeasure`, which re-initializes
those variables. It is ugly, but it works and is, IMHO better than copying
the complete source of Switch to application.
