Question

我把图像放在导航抽屉里，但我看不到。

这是我的activity_main.xml

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MyActivity">

    <FrameLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >


    </FrameLayout>
    <LinearLayout
        android:layout_width="@dimen/navigation_drawer_width"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:layout_gravity="start">
        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/imageView2"
            android:src="@drawable/ocio"
            android:layout_gravity="left|center_vertical" />
        <fragment android:id="@+id/navigation_drawer"
            android:layout_width="@dimen/navigation_drawer_width"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            android:name="otcproject.v1.navigationdrawer.NavigationDrawerFragment"
            tools:layout="@layout/fragment_navigation_drawer" />
    </LinearLayout>
</android.support.v4.widget.DrawerLayout>

这是我的MainActivity

public class MainActivity extends FragmentActivity implements NavigationDrawerFragment.NavigationDrawerCallbacks{

 protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mNavigationDrawerFragment = (NavigationDrawerFragment)
                getFragmentManager().findFragmentById(R.id.navigation_drawer);
        mTitle = getTitle();
               // Set up the drawer.
        mNavigationDrawerFragment.setUp(
                R.id.navigation_drawer,
                (DrawerLayout) findViewById(R.id.drawer_layout));

应用程序运行，我可以看到选项navigationdrawer，但我看不到图像标题。

问题是片段的_emailAddress = Settings.EmailAddress; string clientSecret = Settings.ClientSecret; string clientId = Settings.ClientId; ClientSecrets clientSecrets = new ClientSecrets {ClientId = clientId, ClientSecret = clientSecret}; UserCredential credential; credential = GoogleWebAuthorizationBroker.AuthorizeAsync( clientSecrets, Scopes, "user", CancellationToken.None).Result; _service = new GmailService(new BaseClientService.Initializer() { HttpClientInitializer = credential, ApplicationName = "Draft Sender", //applicationName, });。尝试将其高度设置为0dp，将权重设置为1（它将占用所有可用空间，与＆＃34相同; match_parent减去ImageView的高度＆＃34;）。

match_parent

<fragment android:id="@+id/navigation_drawer" android:layout_width="@dimen/navigation_drawer_width" android:layout_height="0dp" android:layout_weight="1" android:layout_gravity="start" android:name="otcproject.v1.navigationdrawer.NavigationDrawerFragment" tools:layout="@layout/fragment_navigation_drawer" />表示视图将匹配其父级的大小，然后您不能拥有包含其内容（ImageView）的视图和与其父级（片段）匹配的另一个视图。第二个将与第一个重叠。

NavigationDrawer片段标题图像
