如何将图像添加到 Android 应用程序中的框架布局？

Question

我正在我的应用程序中构建一个左滑动菜单，我在其中使用了框架布局。在这个框架布局中调用了一个列表视图。

在这个框架布局中，我想调用一个显示用户头像的 imageView。

这是我的导航抽屉的代码，我在其中初始化框架布局并调用它的列表视图。

这是我的导航抽屉代码 -

public class NavigationDrawerFragment extends Fragment {

Context context;

ArrayList prgmName;
public static int [] prgmImages={R.drawable.feedbackgrey,R.drawable.followinggrey,R.drawable.questiongrey,R.drawable.feedbackgrey,
        R.drawable.invitegrey,R.drawable.rategrey,R.drawable.settings};

这里是片段和框架布局 xml

<!-- A DrawerLayout is intended to be used as the top-level content view         
using match_parent for both width and height to consume the full space    
available. -->
<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=".MainActivity">

<!-- As the main content view, the view below consumes the entire
     space available using match_parent in both dimensions. -->
<FrameLayout android:id="@+id/container" android:layout_width="match_parent"
    android:layout_height="match_parent" />

<!-- android:layout_gravity="start" tells DrawerLayout to treat
     this as a sliding drawer on the left side for left-to-right
     languages and on the right side for right-to-left languages.
     If you're not building against API 17 or higher, use
     android:layout_gravity="left" instead. -->
<!-- The drawer is given a fixed width in dp and extends the full height of
     the container. -->
<fragment android:id="@+id/navigation_drawer"
    android:layout_width="@dimen/navigation_drawer_width"   
android:layout_height="match_parent"
    android:layout_gravity="start"
    android:name="navigation.NavigationDrawerFragment"
    tools:layout="@layout/fragment_navigation_drawer" />

</android.support.v4.widget.DrawerLayout>

这是我的列表视图 xml

<ListView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"   
android:layout_width="match_parent"
android:layout_height="match_parent"
android:choiceMode="singleChoice"
android:dividerHeight="0dp"
android:background="#FFFFFF"
tools:context=".NavigationDrawerFragment" />

感谢您的帮助，非常感谢！

Answer 1

您必须在 ListView

的单元格中声明您的 ImageView

Answer 2

您可以添加一个ViewGroup，例如LinearLayout、RelativeLayout等，作为整个banner或imageView的容器。

请参阅下面的 xml 和输出。 XML

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
