LinearLayout in navigation drawer

Question

I want place TextView of bottom ListView in navigation drawer. Throws java.lang.ClassCastException: android.widget.LinearLayout$LayoutParams cannot be cast to android.support.v4.widget.DrawerLayout$LayoutParams

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 xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="0dp"
        android:paddingBottom="4dp"
    />

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:id="@+id/left_drawer"
        android:layout_gravity="start"
        >

        <ListView
            android:id="@+id/left_menu"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:choiceMode="singleChoice"
            android:dividerHeight="0.1dp"
            android:background="#111"
            android:divider="#FFF"
            />

        <TextView
            android:id="@+id/joke_text1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:textSize="16sp"
            android:lineSpacingExtra="5sp"
            android:text="AAAAAA"
            />
    </LinearLayout>

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

and java code:

// Getting reference to the DrawerLayout
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerLinear = (LinearLayout) findViewById(R.id.left_drawer);

leftMenuItems = getResources().getStringArray(R.array.leftMenuItems);

mDrawerList = (ListView) findViewById(R.id.left_menu);
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());

// set a custom shadow that overlays the main content when the drawer opens
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);

// Generate title
String[] title = new String[] { "item1", "item2", "item4", "item4" };

// Generate icon
int[] icon = new int[] { R.drawable.abc_ic_clear, R.drawable.abc_ic_clear,
        R.drawable.abc_ic_clear, R.drawable.abc_ic_clear };


MenuListAdapter adapter = new MenuListAdapter(this, title, icon);

// Setting the adapter on mDrawerList
mDrawerList.setAdapter(adapter);

// Getting reference to the ActionBarDrawerToggle
mDrawerToggle = new ActionBarDrawerToggle(
        this,
        mDrawerLayout,
        R.drawable.ic_drawer,
        R.string.drawer_open,
        R.string.drawer_close) {

    public void onDrawerOpened(View drawerView) {
        vstitle.setText("Menu");
        invalidateOptionsMenu();
    }

    public void onDrawerClosed(View view) {
        vstitle.setText("App");
        invalidateOptionsMenu();
    }


};

// Setting DrawerToggle on DrawerLayout
mDrawerLayout.setDrawerListener(mDrawerToggle);

Hoorray! I found problem in my code. In function selectItem need change mDrawerLayout.closeDrawer(mDrawerList); to mDrawerLayout.closeDrawer(mDrawerLinear); Now it works perfectly! Thanks to all

If you're using Eclipse, try doing a Project->Clean.

Also, remove the xmlns:android="http://schemas.android.com/apk/res/android attribute from you FrameLayout definition in the xml since it's not necessary.

I am uses Android Studio. Project cleaning did not help – LONGMAN Feb 16 '14 at 12:06
Try wrapping the ListView and the TextView inside a new LinearLayout. That way, the LinearLayout that you're using for your menu, will actually have just 1 child view instead of 2. – Henrique Feb 16 '14 at 12:13
