问题
I am building a left slide menu in my app, in which I am using a framelayout. And a listview is called inside this framelayout.
In this frame layout, I want to call a imageView which will display user profile picture.
Here is the code for my navigation drawer, where I am initializing framelayout and calling its listview.
Here is my navigation drawer code -
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};
public static String [] prgmNameList={"Feed","Following","My Question","Profile","Invite Friend","Rate Us","Setting"};
/**
* Remember the position of the selected item.
*/
private static final String STATE_SELECTED_POSITION = "selected_navigation_drawer_position";
/**
* Per the design guidelines, you should show the drawer on launch until the user manually
* expands it. This shared preference tracks this.
*/
private static final String PREF_USER_LEARNED_DRAWER = "navigation_drawer_learned";
/**
* A pointer to the current callbacks instance (the Activity).
*/
private NavigationDrawerCallbacks mCallbacks;
/**
* Helper component that ties the action bar to the navigation drawer.
*/
private ActionBarDrawerToggle mDrawerToggle;
private DrawerLayout mDrawerLayout;
private ListView mDrawerListView;
private View mFragmentContainerView;
private int mCurrentSelectedPosition = 0;
private boolean mFromSavedInstanceState;
private boolean mUserLearnedDrawer;
public NavigationDrawerFragment() {
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
context=getActivity();
// Read in the flag indicating whether or not the user has demonstrated awareness of the
// drawer. See PREF_USER_LEARNED_DRAWER for details.
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(getActivity());
mUserLearnedDrawer = sp.getBoolean(PREF_USER_LEARNED_DRAWER, false);
if (savedInstanceState != null) {
mCurrentSelectedPosition = savedInstanceState.getInt(STATE_SELECTED_POSITION);
mFromSavedInstanceState = true;
}
// Select either the default item (0) or the last selected item.
selectItem(mCurrentSelectedPosition);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
// Indicate that this fragment would like to influence the set of actions in the action bar.
setHasOptionsMenu(true);
}
@Override

Bundle savedInstanceState) {

R.layout.fragment_navigation_drawer, container, false);

selectItem(position);
}
});

// set up the drawer's list view with items and click listener
ActionBar actionBar = getActionBar();

// ActionBarDrawerToggle ties together the the proper interactions

Here is the fragment and framelayout 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>
Here is my listview 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" />
Help is appreciated, thanks so much !
回答1:
you must declare your ImageView in cells of ListView
回答2:
You can add a ViewGroup such as LinearLayout,RelativeLayout,etc.. as a container for the entire banner or imageView.
See the xml and output below. XML
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

<!--What ever your want in the Right drawer, put it in below RelativeLayout -->
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@color/white" >
<!-- TO SHOW FRAGMENTS -->
<FrameLayout
android:id="@+id/mFragmentContainer"
