在android中使用导航抽屉创建基本活动

我尝试按照this回答,主要想法是覆盖setContentView中的BaseActivity,这项活动将由所有活动扩展,因此{{1}将有导航抽屉。

但是,在我尝试实施答案后,我的导航从未显示(即使在BaseActivity中)。这就是我所做的:

这是导航抽屉的xml:

BaseActivity

这是我的主调<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent" > <!-- Framelayout to display Fragments --> <FrameLayout android:id="@+id/frame_container" android:layout_width="match_parent" android:layout_height="match_parent" /> <!-- Listview to display slider menu --> <ListView android:id="@+id/list_slidermenu" android:layout_width="120dp" android:layout_height="match_parent" android:layout_gravity="start" android:background="@color/list_background" android:choiceMode="singleChoice" android:divider="@color/list_divider" android:dividerHeight="1dp" android:listSelector="@drawable/list_selector" /> </android.support.v4.widget.DrawerLayout> (在setContentView中):

BaseActivity

这是我@Override public void setContentView(int layoutResID) { // TODO Auto-generated method stub mDrawerLayout= (DrawerLayout) getLayoutInflater().inflate(R.layout.activity_main, null); // Your base layout here actContent= (FrameLayout) mDrawerLayout.findViewById(R.id.frame_container); //listLayout = (LinearLayout) mDrawerLayout.findViewById(R.id.listLayout); getLayoutInflater().inflate(layoutResID, actContent, true); //getLayoutInflater().inflate(layoutResID, listLayout, true); super.setContentView(layoutResID); } 上的onCreate,请注意我使用BaseActivity代替getLayoutInflater().inflate

setContentView

最后,我只需像往常一样扩展@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //setContentView(R.layout.activity_main); //getSupportActionBar().setDisplayShowHomeEnabled(false); //getSupportActionBar().setDisplayShowCustomEnabled(true); // enabling action bar app icon and behaving it as toggle button getSupportActionBar().setDisplayHomeAsUpEnabled(true); getSupportActionBar().setHomeButtonEnabled(true); mTitle = mDrawerTitle = getTitle(); // load slide menu items navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items); // nav drawer icons from resources navMenuIcons = getResources() .obtainTypedArray(R.array.nav_drawer_icons); //mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); mDrawerLayout= (DrawerLayout) getLayoutInflater().inflate(R.layout.activity_main, null); //mDrawerList = (ListView) findViewById(R.id.list_slidermenu); mDrawerList = (ListView) mDrawerLayout.findViewById(R.id.list_slidermenu); navDrawerItems = new ArrayList<NavDrawerItem>(); // adding nav drawer items to array // Home navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1))); // Find People navDrawerItems.add(new NavDrawerItem(navMenuTitles[1], navMenuIcons.getResourceId(1, -1))); // Photos navDrawerItems.add(new NavDrawerItem(navMenuTitles[2], navMenuIcons.getResourceId(2, -1))); // Communities, Will add a counter here navDrawerItems.add(new NavDrawerItem(navMenuTitles[3], navMenuIcons.getResourceId(3, -1))); // Pages navDrawerItems.add(new NavDrawerItem(navMenuTitles[4], navMenuIcons.getResourceId(4, -1))); // What's hot, We will add a counter here navDrawerItems.add(new NavDrawerItem(navMenuTitles[5], navMenuIcons.getResourceId(5, -1))); // Recycle the typed array navMenuIcons.recycle(); mDrawerList.setOnItemClickListener(new SlideMenuClickListener()); // setting the nav drawer list adapter adapter = new NavDrawerListAdapter(getApplicationContext(), navDrawerItems); mDrawerList.setAdapter(adapter); mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_drawer, //nav menu toggle icon R.string.app_name, // nav drawer open - description for accessibility R.string.app_name // nav drawer close - description for accessibility ) { public void onDrawerClosed(View view) { getSupportActionBar().setTitle(mTitle); // calling onPrepareOptionsMenu() to show action bar icons invalidateOptionsMenu(); } public void onDrawerOpened(View drawerView) { getSupportActionBar().setTitle(mDrawerTitle); // calling onPrepareOptionsMenu() to hide action bar icons invalidateOptionsMenu(); } }; mDrawerLayout.setDrawerListener(mDrawerToggle); if (savedInstanceState == null) { // on first time display view for first nav item displayView(0); } } 类和代码。

更新

根据答案,这是我的工作覆盖BaseActivity

setContentView

答案 0 :(得分:7)

像这样改变你的setContentView() ......

@Override
public void setContentView(int layoutResID) {
    mDrawerLayout = (DrawerLayout) getLayoutInflater().inflate(R.layout.activity_main, null); 
    actContent = (FrameLayout) mDrawerLayout.findViewById(R.id.frame_container);
    // set the drawer layout as main content view of Activity.
    setContentView(mDrawerLayout);
    // add layout of BaseActivities inside framelayout.i.e. frame_container
    getLayoutInflater().inflate(layoutResID, actContent, true);
}

答案 1 :(得分:3)

我知道这已经得到了回答,但万一有人在解决我的具体问题:

DrawerLayout只能有2个孩子,contentnavigationView。 如果要包含工具栏,则应将其包含在另一个布局内或drawerlayout

之外
DrawerLayout
--LinearLayout (or any other layout)
----Toolbar
----Content
--NavigationView

或:

LinearLayout (or any other layout)
--Toolbar
--DrawerLayout
----Content
----NavigationView
