Android 噴氣背包組件 - 在導航抽屜點擊烤面包

Question

我正在使用導航噴氣背包並設置了導航抽屜。 每件事都很好。 但問題是我想在用戶單擊“nav_share”時顯示祝酒詞，但沒有顯示...

這是我制作導航抽屜的方法

DrawerLayout drawer = findViewById(R.id.drawer_layout);
        NavigationView navigationView = findViewById(R.id.nav_view);

        navigationView.setNavigationItemSelectedListener(this);

        mAppBarConfiguration = new AppBarConfiguration.Builder(
                R.id.navigation_home, R.id.navigation_dashboard, R.id.navigation_plan, R.id.navigation_notifications)
                .setDrawerLayout(drawer)
                .build();

        NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
        NavigationUI.setupActionBarWithNavController(this, navController, mAppBarConfiguration);
        NavigationUI.setupWithNavController(navigationView, navController);

我的導航抽屜菜單是

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    tools:showIn="navigation_view">

    <group android:checkableBehavior="single">
        <item
            android:id="@+id/nav_home"
            android:icon="@drawable/ic_menu_camera"
            android:title="@string/menu_home" />
        <item
            android:id="@+id/nav_gallery"
            android:icon="@drawable/ic_menu_gallery"
            android:title="@string/menu_gallery" />
        <item
            android:id="@+id/nav_slideshow"
            android:icon="@drawable/ic_menu_slideshow"
            android:title="@string/menu_slideshow" />
        <item
            android:id="@+id/nav_tools"
            android:icon="@drawable/ic_menu_manage"
            android:title="@string/menu_tools" />
    </group>

    <item android:title="Communicate">
        <menu>
            <item
                android:id="@+id/nav_share"
                android:icon="@drawable/ic_menu_share"
                android:title="@string/menu_share" />
            <item
                android:id="@+id/nav_send"
                android:icon="@drawable/ic_menu_send"
                android:title="@string/menu_send" />
        </menu>
    </item>

</menu>

最后：

@Override
    public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {

        int id = menuItem.getItemId();

        if (id == R.id.nav_share)
            Toast.makeText(LauncherActivity.this, "Click", Toast.LENGTH_SHORT).show();

        DrawerLayout drawer = findViewById(R.id.drawer_layout);
        drawer.closeDrawer(GravityCompat.START);
        return true;
    }

我想要那個點擊吐司……我看不到我錯過了什么……

Answer 1

如果有人想要答案..我做了一些研究，終於找到了解決方案...希望它有所幫助....

NavigationView navigationView = findViewById(R.id.nav_view);
MenuItem shareItem = navigationView.getMenu().findItem(R.id.nav_share);
shareItem.setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() {
     @Override
     public boolean onMenuItemClick(MenuItem item) {

     Toast.makeText(LauncherActivity.this, "click", Toast.LENGTH_SHORT).show();
     //do as you want with the button click

      DrawerLayout drawer = findViewById(R.id.drawer_layout);
      drawer.closeDrawer(GravityCompat.START);

      return true;
     }
 });

用這個

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

我也遇到了你的問題並想出了解決方案

NavController navController = Navigation.findNavController(this, R.id.nav_host_home);
    NavigationUI.setupWithNavController(navigationView, navController);

    navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
        @Override
        public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
            int id = menuItem.getItemId();
            if (id == R.id.nav_share) {
                Toast.makeText(getApplicationContext(), "nav_share", Toast.LENGTH_SHORT).show();
            }
            NavigationUI.onNavDestinationSelected(menuItem, navController);
            drawerLayout.closeDrawer(Gravity.RIGHT);
            return true;
        }
    });
