Set transparent color in android

Set color to #AARRGGBB where AA is the alpha channel.

#00000000 - full transparency
#80FFFFFF - 50% white
#CCFFFFFF - 80% white

Alpha channel values:

100% — FF

Fix status bar transparency

Note the adjusting the insets is a specific workaround for views that do not respect layout settings. View Pager has such problems.

@TargetApi(Build.VERSION_CODES.LOLLIPOP)
private void setStatusBarTransparent() {
  if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    getWindow().getDecorView().setSystemUiVisibility(
          View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_STABLE);

getWindow().setStatusBarColor(Color.TRANSPARENT);

SearchView styles

Two good resources philio.me novoda

v21 example:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="searchViewStyle">@style/AppTheme.SearchView</item>

Change MyLocation button position

It's easy to enable Zoom and MyLocation buttons but annoying to change where they overlay the Map.

Options

Use Map padding (are that will not overlap map controls)
Disable them and implement your own (probably safer than hack below)
Find the buttons by id and alter the layout params

	# Hierarchy Viewer only works by default with phones running a developer version of the Android OS.
	#
	# 1. Phone running Jellybean or higher: add the environment variable: ANDROID_HVPROTO=ddm
	# 2. You can run Hierarchy Viewer on an emulated phone.
	# 3. Use the ViewServer library for pre Jellybean phone

	# set this environment variable
	$ export ANDROID_HVPROTO=ddm;

	# To add navigation back to the main activity using the
	# Toolbar (material design), we do three things:

	# 1. Declare the parent activity in the AndroidManifest.xml
	#
	# <activity android:name=".MySubActivity" android:label="@string/title_sub_activity" >
	# <meta-data android:name="android.support.PARENT_ACTIVITY" android:value=".MainActivity" />
	# </activity>

	# 2. Configure the Toolbar in MySubActivity:

	*/
	// Creating an instance of Student class with user input data
	Student student = new Student(mNameTV.getText().toString(),
	Integer.parseInt(mAgeTV.getText().toString()),
	mAddressTV.getText().toString(),
	mCourseTV.getText().toString());
