我尝试从支持库 13 中实现最新的抽屉布局。使用以下代码,抽屉始终显示在 gridview 下方。即使我尝试调用 bringToFront() 仍然无法正常工作。能帮忙找出问题所在吗?谢谢。
activity_main.xml
<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
android:id="@+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<ListView
android:id="@+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp"
android:background="#111"/>
</android.support.v4.widget.DrawerLayout>
member_home_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<GridView
android:id="@+id/member_home_thumbnail_grid"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:columnWidth="90dp"
android:gravity="center"
android:horizontalSpacing="0dp"
android:numColumns="auto_fit"
android:stretchMode="columnWidth"
android:verticalSpacing="0dp" >
</GridView>
</LinearLayout>
主要活动:
public class BaseRootActivity extends BaseActivity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private String[] mMainMenus;
public ListView getDrawerListView() {
return this.mDrawerList;
}
@Override

super.onCreate(savedInstanceState);

mMainMenus = this.getResources().getStringArray(R.array.main_menu_array);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) this.findViewById(R.id.left_drawer);
// set up the drawer's list view with items and click listener
mDrawerList.setAdapter(new ArrayAdapter<String>(this, R.layout.drawer_list_item, mMainMenus));
// enable ActionBar app icon to behave as action to toggle nav drawer
getActionBar().setDisplayHomeAsUpEnabled(true);
getActionBar().setHomeButtonEnabled(true);
// ActionBarDrawerToggle ties together the the proper interactions
// between the sliding drawer and the action bar app icon
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_close) {
public void onDrawerClosed(View view) {
getActionBar().setTitle("actionbar title");
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView) {
getActionBar().setTitle("drawer title");
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
}

在主要片段中
public class MemberHomeFragment extends Fragment implements OnItemClickListener {
private GridView mGridListView;
private UserThumbnailAdapter memberAdapter;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.member_home_layout, container, false);
mGridListView = (GridView) rootView.findViewById(R.id.member_home_thumbnail_grid);
mGridListView.setOnItemClickListener(this);
memberAdapter = new UserThumbnailAdapter(this.getActivity(), null);
mGridListView.setAdapter(memberAdapter);
this.startLoading(); // load thumbnails
return rootView;
