Ich bin mit der Material-Navigationsschublade rum, aber es rutscht nicht heraus. Wenn ich auf das Symbol oben links lege, wird die Navigationsleiste nicht angezeigt. Ich kann nicht herausfinden, was ich vermisse.Android-Navigationsschublade rutscht nicht aus
Es gleitet korrekt aus, wenn ich auf dem Bildschirm von links nach rechts wische. Es wird jedoch nicht angezeigt, wenn Sie auf das Schubladensymbol in der oberen linken Ecke klicken.
Dies ist Teil meiner Aktivität:
public class MainActivity extends AppCompatActivity {
private DrawerLayout drawerLayout;
private Toolbar toolbar;
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
// Create the adapter that will return a fragment for each of the three
// primary sections of the activity.
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
initNavigationDrawer();
}
public void initNavigationDrawer() {
NavigationView navigationView = (NavigationView)findViewById(R.id.navigation_view);
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
int id = menuItem.getItemId();
switch (id){
case R.id.home:
Toast.makeText(getApplicationContext(),"Home", Toast.LENGTH_SHORT).show();
drawerLayout.closeDrawers();
break;
case R.id.settings:
Toast.makeText(getApplicationContext(),"Settings",Toast.LENGTH_SHORT).show();
break;
case R.id.logout:
finish();
}
return true;
}
});
View header = navigationView.getHeaderView(0);
TextView tv_email = (TextView)header.findViewById(R.id.tv_email);
tv_email.setText("[email protected]");
drawerLayout = (DrawerLayout)findViewById(R.id.drawer);
ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.drawer_open,R.string.drawer_close){
@Override
public void onDrawerClosed(View v){
super.onDrawerClosed(v);
}
@Override
public void onDrawerOpened(View v) {
super.onDrawerOpened(v);
}
};
drawerLayout.addDrawerListener(actionBarDrawerToggle);
actionBarDrawerToggle.syncState();
}
}
