- 我是新手，我正在学习使用Android Studio导航抽屉活动模板代码（mainMenu.java） 开始这个项目
- 我创建了另一个空活动（viewProfile.java），以便在用户按导航抽屉菜单时调用它。示例：用户按＆＃39;查看个人资料＆＃39;在菜单里面。
- 我需要有关如何在我的所有活动中使用单个Navi Drawer菜单的帮助，例如viewProfile.java Activity。
- 尝试从mainMenu.java复制与Navi Drawer相关的所有代码并粘贴到viewProfile.java中。遗憾的是，根本不起作用。
- 我评论了一些我尝试过的代码。
mainMenu.java
public class mainMenu extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
//Defining views
private TextView editTextUserName;
private TextView textView_profile_name;
private TextView textView_profile_email;

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_menu);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
@Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}

建议在这种情况下使用多个片段而不是活动。但即使您仍想使用不同的活动，也只需在其他活动中包含导航抽屉，就像在其中一个活动中实施一样。然而，这导致多次写入同一段代码，应该避免这种情况。
答案 1 :(得分：0)
使用片段和容器，这样如果您想更改布局，您只能更改布局的一部分而不是整个布局。因此，您的导航抽屉在您的应用中保持安全。
答案 2 :(得分：0)
你应该为此使用片段，你可以为此获得大量的演示..如果你还想使用活动，你必须在每个布局中包含nevigation

我正在使用这个方法
@Override
public void onDrawerItemSelected(View view, int position) {
base.displayView(position);
}
所以你必须在每个活动中实现这个方法，并通过调用任何活动使它们完成..
