Question

我将此抽屉布局用作导航抽屉。如何将项目单击侦听器设置为其中的项目。例如，我在抽屉布局中有Home，Maps和About，我想在每个项目点击上打开新片段。

private DrawerLayout mDrawerLayout;
    private ActionBarDrawerToggle mActionBarDrawerToggle;
    private ScrimInsetsFrameLayout mScrimInsetsFrameLayout;

private void init_navigator(){
    // Navigation Drawer
    mDrawerLayout = (DrawerLayout) findViewById(R.id.main_activity_DrawerLayout);
    mDrawerLayout.setStatusBarBackgroundColor(getResources().getColor(R.color.primaryDark));
    mScrimInsetsFrameLayout = (ScrimInsetsFrameLayout) findViewById(R.id.main_activity_navigation_drawer_rootLayout);

    mActionBarDrawerToggle = new ActionBarDrawerToggle
            (
                    this,
                    mDrawerLayout,
                    toolbar,
                    R.string.navigation_drawer_opened,
                    R.string.navigation_drawer_closed
            )
    {
        @Override
        public void onDrawerSlide(View drawerView, float slideOffset)
        {
            // Disables the burger/arrow animation by default
            super.onDrawerSlide(drawerView, 0);
        }
    };

    mDrawerLayout.setDrawerListener(mActionBarDrawerToggle);

    if (getSupportActionBar() != null)
    {
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setDisplayShowHomeEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);
    }

    mActionBarDrawerToggle.syncState();

    // Navigation Drawer layout width
    int possibleMinDrawerWidth = UtilsDevice.getScreenWidth(this) -
            UtilsMiscellaneous.getThemeAttributeDimensionSize(this, android.R.attr.actionBarSize);
    int maxDrawerWidth = getResources().getDimensionPixelSize(R.dimen.navigation_drawer_max_width);

    mScrimInsetsFrameLayout.getLayoutParams().width = Math.min(possibleMinDrawerWidth, maxDrawerWidth);
    // Set the first item as selected for the first time
    getSupportActionBar().setTitle(R.string.toolbar_title_home);


}

你应该有这样的东西：

public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {}

和

@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
    // Handle navigation view item clicks here.
    int id  = item.getItemId();
    switch (id){
        case R.id.nav_dashboard:
            return true;
        case R.id.nav_maps:
            return true;
        case R.id.nav_user_management:
            return  true;
        case R.id.nav_view:
            return true;
    }
    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.main_activity_DrawerLayout);

    drawer.closeDrawer(GravityCompat.START);
    return true;
}

在创建新项目时尝试导航抽屉活动以获得更好的导航抽屉。
