I have created a demo and its working fine,onPrepareActionMode gets called each time the action mode is shown. Always called after onCreateActionMode, but may be called multiple times if the mode is invalidated. [ I request any one to make a small edit. I need status bar color same as that of toolbar but dynamically, … Read more
Fixed my problem by using MainActivity.this (or YourActivityName.this) AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(MainActivity.this); Make sure you already Theme.AppCompat and extending AppCompatActivity.
If you are using new androidx implementations, when typing Toolbar, the Studio will autocomplete it to android.support.v7.widget.Toolbar, but you should use androidx.appcompat.widget.Toolbar instead, otherwise you will get this error.
com.android.support:appcompat-v7:21+ added support for tinting widgets on devices running pre android 5.1 (API Level 21). To make use of it make sure you extend or set the AppCompat Theme and use app:backgroundTint instead of android:backgroundTint. Example: <android.support.design.widget.FloatingActionButton xmlns:app=”http://schemas.android.com/apk/res-auto” android:id=”@+id/fab” android:layout_width=”wrap_content” android:layout_height=”wrap_content” android:layout_margin=”16dp” android:src=”https://stackoverflow.com/questions/30870443/@drawable/icon” app:backgroundTint=”@color/accent” app:borderWidth=”0dp” />
For me, Even after upgrading to appcompat-v7:22.1.0, in which AppCompatActivty is added, the problem was not resolved for me, Android Studio was giving same problem Cannot resolve symbol ‘AppCompatActivity’ Sometimes clearing the android studio caches help. In android studio I just cleared the caches and restarted with the following option– File->Invalidate Caches/Restart
You need to use setImageResource() method. imageButton.setImageResource(R.drawable.eng2);

I faced the same issue and after reading the ActionBar documentation, and especially the following quote I found a solution. Beginning with Android … Read more
I’m developing an app that needs to look similar in all devices with >= API14 when it comes to actionbar and statusbar customization. I’ve finally found a solution and since it took a bit of my time I’ll share it to save some of yours. We start by using an appcompat-21 dependency. Transparent Actionbar: values/styles.xml: … Read more
First, you should know now the android.support.v4.app.ActionBarDrawerToggle is deprecated. You must replace that with android.support.v7.app.ActionBarDrawerToggle. Here is my example and I use the new Toolbar to replace the ActionBar. MainActivity.java public class MainActivity extends ActionBarActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Toolbar mToolbar = (Toolbar) findViewById(R.id.toolbar); setSupportActionBar(mToolbar); DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); … Read more
again this is all in the link you supplied to change the text to white all you have to do is change the theme. use this theme <android.support.v7.widget.Toolbar xmlns:android=”http://schemas.android.com/apk/res/android” xmlns:app=”http://schemas.android.com/apk/res-auto” android:id=”@+id/activity_my_toolbar” android:layout_width=”match_parent” android:layout_height=”wrap_content” android:minHeight=”?attr/actionBarSize” android:background=”?attr/colorPrimary” app:theme=”@style/ThemeOverlay.AppCompat.Dark.ActionBar” app:popupTheme=”@style/ThemeOverlay.AppCompat.Light”/>
