我在我的代码中不断收到这个警告,我开始担心,因为我接近完成的最后期限。我的主要活动中有一个 DrawerLayout,使用 Android Studio 自己的导航抽屉活动,但由于 DrawerLayout setDrawerListener 现在已弃用,因此必须对代码进行轻微更改。
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Firebase reference to main application URL and 'today's' matches
Firebase mainRef = new Firebase(cons.getFirebaseUrl());
//DrawerLayout settings for the navigation drawer
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.addDrawerListener(toggle);
toggle.syncState();
//Retrieve the navigation drawer and set it's listener for menu item presses
navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
我收到警告drawer.addDrawerListener(toggle)
并且navigationView.setNavigationItemSelectedListener(this)
在我的代码中,我也通过这种方法接收它:
@Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) // This line gets the warning {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
提前感谢任何可能知道是什么原因的人。我已经搜索了这个问题,但我找不到关于 post deprecated 方法的示例。
