how can delete this blue and green section!? do some different ways but not work!
mainActivity:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main_page);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.addTab(tabLayout.newTab().setText("News"));
tabLayout.addTab(tabLayout.newTab().setText("Archive"));
tabLayout.addTab(tabLayout.newTab().setText("Shop"));
tabLayout.addTab(tabLayout.newTab().setText("Beat Store"));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
final ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
final PagerAdapter adapter = new PagerAdapter(getSupportFragmentManager(), tabLayout.getTabCount());
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
}

App Bar Layout is green but when i delete that my tabs gone! and that blue section seems not any where but always there :|
Extend class with AppCompatActivity
public class MainActivity extends AppCompatActivity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Other initializations
}
}
Declare different theme for this Activity in Manifest File
<activity
android:name=".MainActivity"
android:theme="#style/AppTheme.FullScreenTheme">
...
Now in styles.xml
<style name="AppTheme.FullScreenTheme" parent="#style/AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
</style>
If your layout is having any android.support.v7.widget.Toolbar component, remove that also
remove android:background="#71ff76" from android.support.design.widget.AppBarLayout and remove the mentioned padding android:paddingTop="#dimen/appbar_padding_top"

I'm new in android studio.
I'm hope to open url with User.java(has been data-binding), but the code is not working.
Could someone give some advice?
Thanks
Edit: OpenURL method is called in activity_main.xml
Edit: I have found problems.
User.java
public class User {
Context context;
String url;
public User(Context context, String url) {
this.context = context;
this.url = url;
}
public void OpenURL() {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
context.startActivity(intent);
}
}
MainActivity.java
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ActivityMainBinding activityMainBinding = DataBindingUtil.setContentView(this, R.layout.activity_main);
User user = new User(getApplicationContext(),"https://www.google.com.tw/?hl=zh_TW");
activityMainBinding.setUser(user);

thank you to all the helpers
can you please share the crashing error? It's hard to figure out the error. If you can also add how to reproduce the crash it can be very helpful
You forgot to initialize NavHostFragent
so kindly Initiliaze In your OnCreate
NavHostFragment navHostFragment = (NavHostFragment) getSupportFragmentManager()
.findFragmentById(R.id. fragmentContainerView);
NavController navController = navHostFragment.getNavController();
and for the navigate one fragment to another fragment use navigate
homeBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {navController.navigate(R.id. action_startFragment_to_registerFragment
}
});)
I want to change the text in message when the button is clicked to "Hello World!".The idea would be that it would use a method inorder to change the text from a blank TextView into one that has writing on.

</android.support.design.widget.CoordinatorLayout>
I am new to android development and was trying to build an app with a navigation drawer and tab view in conjunction. I was referring to this
to build the code. I managed to build a login page which would lead to an other activity page. Its over here that I am facing an issue.I want the tabs only for the "home" drawer item not for the rest of the drawer item.
The navigation drawer output is fine
and its clickable. I referred online but couldn't narrow down to any solution.
activity_main2.xml (tab integration and navigation drawer):
