android - NavigationDrawer menuItem setChecked 不起作用

Question

我使用 Android 支持设计库中的 NavigationDrawer 创建了一个 BaseActivity。

public abstract class BaseActivity extends ActionBarActivity {  

final static int MENUITEMS = 5;

private Toolbar toolbar;                              // Declaring the Toolbar Object

NavigationView navigationView;
private DrawerLayout drawerLayout;

Context basecontext;

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

    setContentView(getLayoutId());

/* Assinging the toolbar object ot the view
and setting the the Action bar to our toolbar
 */
    toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    //Initializing NavigationView

    //Setting Navigation View Item Selected Listener to handle the item click of the navigation menu
    navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {

        // This method will trigger on item Click of navigation menu
        @Override
        public boolean onNavigationItemSelected(MenuItem menuItem) {


            //Checking if the item is in checked state or not, if not make it in checked state
            if (menuItem.isChecked()) {
                menuItem.setChecked(false);

            } else {
                menuItem.setChecked(true);
                switch (menuItem.getItemId()) {


                    //Replacing the main content with ContentFragment Which is our Inbox View;
                    case R.id.menu_start:
                        Toast.makeText(getApplicationContext(), "Noch nicht implementiert", Toast.LENGTH_SHORT).show();
                        Intent intent = new Intent(BaseActivity.this, Start.class);
                        startActivity(intent);
                        // For rest of the options we just show a toast on click
                        //TODO

                    case R.id.menu_all_entries:
                        Toast.makeText(getApplicationContext(), "Noch nicht implementiert", Toast.LENGTH_SHORT).show();
                    case R.id.menu_missed_entries:
                        Toast.makeText(getApplicationContext(), "Noch nicht implementiert", Toast.LENGTH_SHORT).show();
                    case R.id.menu_diagram:
                        Toast.makeText(getApplicationContext(), "Noch nicht implementiert", Toast.LENGTH_SHORT).show();
                    case R.id.menu_export:
                        Toast.makeText(getApplicationContext(), "Noch nicht implementiert", Toast.LENGTH_SHORT).show();
                    default:
                        Toast.makeText(getApplicationContext(), "Somethings Wrong", Toast.LENGTH_SHORT).show();

                }
            }

            //Closing drawer on item click
            drawerLayout.closeDrawers();
            //String localClassName = getLocalClassName();
            //Check to see which item was being clicked and perform appropriate action
            return true;

        }
    });

这很好用。

现在我有一个“子” Activity (没有表示为菜单项的 Activity )。

在这个 Activity 中:

public class AddEntryPage1 extends BaseActivity {


@Override
protected int getLayoutId(){
    return R.layout.activity_add_entry_page1;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ButterKnife.bind(this);
    for(int i=0;i<MENUITEMS;i++){
        navigationView.getMenu().getItem(0).setChecked(false);
    }
}
}

我试图将我所有的菜单项设置为未选中，但没有任何反应。

当我计算表达式时

navigationView.getMenu().getItem(0).isChecked()

它总是正确的(在 for循环/getItem(0).setChecked(false)).

我也没有收到任何错误。

好像我没有写权限？我用选定的项目启动我的 drawer.xml 是否有问题？当我单击另一个菜单项时，所选项目会按预期更改。还是 checkableBehavior="single"意味着必须检查一项？

<group android:checkableBehavior="single">

    <item
        android:id="@+id/menu_start"
        android:checked="true"
        android:icon="@drawable/ic_action_home"
        android:title="Start" />

    <item
        android:id="@+id/menu_all_entries"
        android:checked="false"
        android:icon="@drawable/ic_action_view_list"
        android:title="Alle Einträge" />

    <item
        android:id="@+id/menu_missed_entries"
        android:checked="false"
        android:icon="@drawable/ic_action_view_list"
        android:title="Verpasste Einträge" />

    <item
        android:id="@+id/menu_diagram"
        android:checked="false"
        android:icon="@drawable/ic_editor_insert_chart"
        android:title="Diagramm" />


    <item
        android:id="@+id/menu_export"
        android:checked="false"
        android:icon="@drawable/ic_social_share"
        android:title="Export" />

</group>

谢谢你帮助我!
