Methods Summary
public static intcombineMeasuredStates(int curState, int newState)
Merge two states as returned by {@link ViewCompat#getMeasuredState(android.view.View)} ()}.

param
curState The current state as returned from a view or the result of combining multiple views.
param
newState The new view state to combine.
return
Returns a new integer reflecting the combination of the two states.

        return curState | newState;
public static voidcomputeFitSystemWindows(android.view.View view, android.graphics.Rect inoutInsets, android.graphics.Rect outLocalInsets)
Allow calling the hidden method {@code computeFitSystemWindows(Rect, Rect)} through reflection on {@code view}.

        if (sComputeFitSystemWindowsMethod != null) {
            try {
                sComputeFitSystemWindowsMethod.invoke(view, inoutInsets, outLocalInsets);
            } catch (Exception e) {
                Log.d(TAG, "Could not invoke computeFitSystemWindows", e);
            }
        }
public static booleanisLayoutRtl(android.view.View view)

        return ViewCompat.getLayoutDirection(view) == ViewCompat.LAYOUT_DIRECTION_RTL;
public static voidmakeOptionalFitsSystemWindows(android.view.View view)
Allow calling the hidden method {@code makeOptionalFitsSystem()} through reflection on {@code view}.

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
            try {
                // We need to use getMethod() for makeOptionalFitsSystemWindows since both View
                // and ViewGroup implement the method
                Method method = view.getClass().getMethod("makeOptionalFitsSystemWindows");
