Use a ViewSwitcher to put two widgets where only one can fit. This is useful if you want to save space in your UI but don't want to give up multiple features.
public class OnClickListenerActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
commutateViewSwitcherButton.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
final ViewSwitcher viewSwitcher = (ViewSwitcher) findViewById(R.id.viewSwitcher);

Hide Menu Item from ActionBar - Menu if the device doesn't support a certain feature.
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getSupportMenuInflater();
inflater.inflate(R.menu.menu, menu);
//Let's say we want to remove a "Share with Bluetooth" item from our Action Bar/Menu
PackageManager pm = getPackageManager();
if (!pm.hasSystemFeature(PackageManager.FEATURE_BLUETOOTH)) {
MenuItem item = menu.findItem(R.id.bluetoothSharing);
item.setVisible(false);

Android - Custom ColorFilter to apply new solid color to a Drawable.
ColorFilter getColorFilterFromColor(int color){
//Extract the RGB components from color
int red = Color.red(color);
int green = Color.green(color);
int blue = Color.blue(color);
//create a ColorMatrix with the RGB Components
float[] matrix = {
0, 0, 0, 0, red
