Question

当我向导航栏添加标题时出现此错误

android.view.InflateException：二进制XML文件行＃0：错误膨胀类android.support.design.widget.NavigationView但是没有标题，它可以正常工作。

第一个文件是MainActivity，它包含四个片段和底部导航第二个是acivity_main.xml布局我认为错误可能在styles.xml文件中，这就是为什么我也把它放了。

 public class MainActivity extends AppCompatActivity {
    private BottomNavigationView.OnNavigationItemSelectedListener 
    mOnNavigationItemSelectedListener
            = new BottomNavigationView.OnNavigationItemSelectedListener() {

        @Override
        public boolean onNavigationItemSelected(@NonNull MenuItem item) {
            switch (item.getItemId()) {
                case R.id.home:
                    setTitle("Home");
                    HomeFragment fragmentTasks = new HomeFragment();
                    FragmentTransaction fragmentTransactionTasks = getSupportFragmentManager().beginTransaction();
                    fragmentTransactionTasks.replace(R.id.frame_layout, fragmentTasks);
                    fragmentTransactionTasks.commit();

                    return true;
                case R.id.notification:
                    setTitle("Notification");
                    NoteFragment fragmentQA = new NoteFragment();
                    FragmentTransaction fragmentTransactionQa = getSupportFragmentManager().beginTransaction();
                    fragmentTransactionQa.replace(R.id.frame_layout, fragmentQA);
                    fragmentTransactionQa.commit();

                    return true;
                case R.id.profile:
                    setTitle("Profile");
                    ProFragment fragmentCashOut = new ProFragment();
                    FragmentTransaction fragmentTransactionCashout = getSupportFragmentManager().beginTransaction();
                    fragmentTransactionCashout.replace(R.id.frame_layout, fragmentCashOut);
                    fragmentTransactionCashout.commit();

                    return true;
                case R.id.help:
                    setTitle("Help");
                    HelpFragment fragmentDiscuss = new HelpFragment();
                    FragmentTransaction fragmentTransactionDiscuss = getSupportFragmentManager().beginTransaction();
                    fragmentTransactionDiscuss.replace(R.id.frame_layout, fragmentDiscuss);
                    fragmentTransactionDiscuss.commit();

                    return true;
            }
            return false;
        }
    };


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        BottomNavigationView navigation =findViewById(R.id.navigation);
        navigation.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener);

        setTitle("Home");

        HomeFragment fragmentTasks = new HomeFragment();
        FragmentTransaction fragmentTransactionTasks = getSupportFragmentManager().beginTransaction();
        fragmentTransactionTasks.replace(R.id.frame_layout, fragmentTasks);
        fragmentTransactionTasks.commit();
    }

Answer 1

我认为你应该尝试评论CircleImageView和textview并测试它是否有效。 nav_header中的某些子视图可能会出现膨胀问题。

我已经在我的IDE上尝试过你的代码并且它可以正常运行

我正在尝试创建导航抽屉，但我有这个错误
