Show Toolbar on other activity Android

I used default navigation drawer of android Studio - created project with Navigation Drawer Activity present on Android Studio. Now i want to show Toolbar on other Activity too. i tried almost everything to get toolbar on main Acitivity but it through NullpointerExpection

MainActivity.java 

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(layout.show_navigation);


        if (android.os.Build.VERSION.SDK_INT > 9) {
            StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
            StrictMode.setThreadPolicy(policy);
        }


        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        toolbar.setLogo(R.drawable.logo);
        setSupportActionBar(toolbar);
        getSupportActionBar().setTitle(null);

        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Snackbar.make(view, "Repalce with custom message ", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();
            }
        });

        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
                this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
        drawer.setDrawerListener(toggle);
        toggle.syncState();

        NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);

here is code of Naviagtion Drawer layout

Solution

  • There are two solutions

    1. For this just create a BaseActivity class that implements the drawer, and let all your other activities extend this one. This is using Activity

    2. If you want a navigation drawer, you should use fragments. follow this tutorial and it works. Using Fragments
