在一个活动中使用两个NavigationView，并在AppBarLayout中使用两个单独的按钮打开和关闭它们

<com.google.android.material.navigation.NavigationView
    android:id="@+id/navView1"
    ... />

<com.google.android.material.navigation.NavigationView
    android:id="@+id/navView2"
    ... />

Button button1 = findViewById(R.id.button1);
Button button2 = findViewById(R.id.button2);

button1.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // 打开第一个NavigationView
        DrawerLayout drawerLayout = findViewById(R.id.drawerLayout);
        NavigationView navView1 = findViewById(R.id.navView1);
        drawerLayout.openDrawer(navView1);
    }
});

button2.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // 打开第二个NavigationView
        DrawerLayout drawerLayout = findViewById(R.id.drawerLayout);
        NavigationView navView2 = findViewById(R.id.navView2);
        drawerLayout.openDrawer(navView2);
    }
});

<androidx.drawerlayout.widget.DrawerLayout
    android:id="@+id/drawerLayout"
    ... >

    <com.google.android.material.appbar.AppBarLayout
        ... >
