单击工具栏上的汉堡包图标不会打开导航抽屉
Clicking hamburger icon on Toolbar does not open Navigation Drawer
我有这个 导航抽屉,它工作得很好。
重构我的代码,我删除了活动中的所有 onOptionsItemSelecteds
,并使所有活动继承自一个基础 activity,它扩展了 AppComplatActivity
和 implements 所有必要的方法。
在点击汉堡包图标后,即使我有 syncstate
() 和所有东西,它也不再起作用。
为什么这不起作用的任何线索?
One of the activities:
public class MainActivity extends BaseActivity implements SearchFilterFragment.OnFragmentInteractionListener {
NavigationView navigationView;
DrawerLayout drawerLayout;
private Tracker mTracker;
@Override
protected void onResume() {
super.onResume();
drawerLayout.openDrawer(GravityCompat.START);
}
@Override
protected void onPostResume() {
super.onPostResume();
mTracker.setScreenName("MainActivity" + "-----");
mTracker.send(new HitBuilders.ScreenViewBuilder().build());
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getWindow().getDecorView().setLayoutDirection(View.LAYOUT_DIRECTION_RTL);
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
drawerLayout.openDrawer(GravityCompat.START);
navigationView = (NavigationView) findViewById(R.id.navigation_view_primary);
navigationView.setNavigationItemSelectedListener(new NavigationDrawerListener(this));
setupToolbar();
Haftdong application = (Haftdong) getApplication();
mTracker = application.getDefaultTracker();
}
private void setupToolbar() {
// Show menu icon
final ActionBar actionBar = getSupportActionBar();
actionBar.setDisplayHomeAsUpEnabled(true);// will make the icon clickable and add the < at the left of the icon.
DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
mDrawerLayout.setDrawerListener(mDrawerToggle);
mDrawerToggle.syncState();//for hamburger icon
}
@Override
public void onFragmentInteraction(Uri uri) {
}
}
基础活动:
public class BaseActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_base, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
您正在为 ActionBarDrawerToggle
使用四参数构造函数,这意味着您必须在 MainActivity
的 onOptionsItemSelected()
中调用开关的 onOptionsItemSelected()
方法覆盖以便 open/close 抽屉。
例如:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if(mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
如果您碰巧提供了自己的 Toolbar
– 例如,作为支持 ActionBar
(尽管没有必要这样设置) – 那么您可以改为传递 Toolbar
作为 ActionBarDrawerToggle
构造函数调用中的第三个参数。例如:
Toolbar toolbar = findViewById(R.id.toolbar);
ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout,
toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
然后抽屉 opening/closing 将由 ActionBarDrawerToggle
内部处理,您无需调用 onOptionsItemSelected()
中的开关。
此设置也不需要 setDisplayHomeAsUpEnabled()
调用,如果您不想将 Toolbar
设置为 ActionBar
,这很方便。
