Question

我有MainActivity，里面集成了谷歌地图和默认的Android导航抽屉。已经尝试了很多东西，但onclick从未被调用。我尝试过使用butterknife onclick，但它从来没有对我有效。

public class MapsActivity extends AppCompatActivity implements OnMapReadyCallback,NavigationView.OnNavigationItemSelectedListener {



 @BindView(R.id.traditional) NavigationView traditionalFood;
  private GoogleMap mMap;
  private ArrayAdapter<String> mAdapter;
  private DrawerLayout drawerLayout;
  private Toolbar toolbar;
  private NavigationView naview;

  @Override protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ButterKnife.bind(this);
    setContentView(R.layout.activity_maps);
    setNavigationViewListner();
    SupportMapFragment mapFragment =
        (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);
    toolbar = (Toolbar) findViewById(R.id.toolbar);
    naview = (NavigationView) findViewById(R.id.traditional);

    setSupportActionBar(toolbar);

    initNavigationDrawer();
  }

 @Override public boolean onNavigationItemSelected(@NonNull MenuItem item) {
    // Handle navigation view item clicks here.
    switch (item.getItemId()) {

      case R.id.traditional: {
       Log.d("onclick","working traditional");
        break;
      }
      case R.id.tips:{
        Log.d("onclick","working tips");
        break;
      }
    }
    //close navigation drawer
    drawerLayout.closeDrawer(GravityCompat.START);
    return true;
  }

  private void setNavigationViewListner() {
    NavigationView navigationView = (NavigationView) findViewById(R.id.navigation_view);
    navigationView.setNavigationItemSelectedListener(this);

  }

Answer 1

尝试在Adk清单中添加新活动

Answer 2

采取以下措施：

NavigationView navigationView = (NavigationView) findViewById(R.id.navigation_view);
navigationView.setNavigationItemSelectedListener(this);

并将它们放在onCreate（）中而不是你正在做的事情。同时使NavigationView navigationView成为字段而不是内部变量

Answer 3

设置内容视图后调用Butterknife.bind

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
ButterKnife.bind(this);

Onclick在导航抽屉里面不起作用
