ClassCastException android.widget.FrameLayout$LayoutParams to android.support.v4.widget.DrawerLayout$LayoutParams

Question

I'm working on the Navigation Drawer for Android. As per my requirement I was to display gridview and listview of items in the navigation drawer. I have created a linearLayout in the layout xml file and placed the two widgets(Grid view, and Listview) in the LinearLayout.

When I run the file I'm getting the following error:

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.navigationdrawer3/com.example.navigationdrawer3.MainActivity}: java.lang.ClassCastException: android.widget.FrameLayout$LayoutParams cannot be cast to android.support.v4.widget.DrawerLayout$LayoutParams

Below are my java, logcat, and NavigationDrawer layout files:

MainActivity.java

public class MainActivity extends Activity {

     private DrawerLayout mDrawerLayout;
        private ListView mDrawerList;
        private ActionBarDrawerToggle mDrawerToggle;

        private CharSequence mDrawerTitle;
        //@SuppressWarnings("unused")
        private CharSequence mTitle;
        private String[] mGalaxyTitles;

        private GridView mDrawerGrid;

        private LinearLayout mDrawerLinear;

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

        mTitle = mDrawerTitle = getTitle();
        mGalaxyTitles = getResources().getStringArray(R.array.items_array);
        mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        mDrawerList = (ListView) findViewById(R.id.left_drawer);

        mDrawerGrid = (GridView)findViewById(R.id.gridview);

        mDrawerLinear =(LinearLayout)findViewById(R.id.linearLayout);

The line of code at line 86:

selectItem(0);

The line of code at line 265:

mDrawerLayout.closeDrawer(mDrawerLayout);

I have tried to correct this run time erroe in many ways but failed to correct. Can any one suggest a answer for my problem.

Solution 1

Answer:

mDrawerLayout.closeDrawer(mDrawerLayout);

had wrong Layout. so change in it with drawerlayout will work it out.

Solution 2

What solved this issue for me:

In MainActivity, add a new field for the LinearLayout, and assign value to it in onCreate() (this part just like emaleavil suggested):

private LinearLayout linearLayout;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // ...
    linearLayout = (LinearLayout) findViewById(R.id.linearLayout);
}

Then in selectItem(), when calling closeDrawer(), simply pass linearLayout as argument:

drawerLayout.closeDrawer(linearLayout);

Solution 3

I had the same problem. I just got rid of using,

mDrawerLayout.closeDrawer(Gravity.LEFT);

Solution 4

I had the same issue... Solution in my case was:

In your MainActivity add:

private LinearLayout linearLayout;

public void onCreate(Bundle savedInstanceState){

    ...
linearLayout = (LinearLayout)findViewById(R.id.linearLayout);
    ...

}

OnPrepareOptionsMenu:

@Override
        public boolean onPrepareOptionsMenu(Menu menu) {
            boolean drawerOpen = mDrawerLayout.isDrawerOpen(this.linearLayout);
            menu.findItem(R.id.action_settings).setVisible(!drawerOpen);
            return super.onPrepareOptionsMenu(menu);
}

I'm sorry for my poor english.

Solution 5

I think you should place your content and drawer exactly as it is siad in the manual. Now yor XML structure doesn't match that. Note, that only the "id" field should match, the view types and parameters may be different.

Have you seen Evernote for Android. They have included a gridview and listview in the DrawerLayout. If they have followed the android developer manual, then how would they got that view. Plz navigate to below link to see the image of Evernote Navigation Drawer. goo.gl/fNDm0K

[Maxim Efimov]

@Seenu69 Just replace the ListView with id "@+id/left_drawer" with a RelativeLayout, for example, with the same id and add anything you want to this layout - grid or listview, or anything else. It will be shown just as on the picture you gave the link to. Also, please, consider the restrictions for content and drawer layout given in the manual - now you don't specify the gravity and width of the drawer.

[Seenu69]

I was unable to get you clearly. Could you post me a sample code of your description. It would be helpful..

[Seenu69]

Hey the I have rectified the error how ever..now the listview is not displaying in the drawerlayout and only gridview is displaying. Can you please help me how can I rectify this...

[Maxim Efimov]

@Seenu69 Did you make any changes in th XML? If you did, please, post the new one.

[Seenu69]

I didn't make changes to the xml file, I have made few changes to the java code previously to make it work correctly..

[Maxim Efimov]

@Seenu69 Well, then I don't know why is's happening, but maybe you can fix it by moving the GreedView and ListView to one layout and set this layout's id to "@+id/left_drawer".

[Jonik]

+1, this pointed me in the right direction. Far more useful than the accepted answer. (For me onPrepareOptionsMenu was not relevant; I just had to pass linearLayout to closeDrawer.)

[Graeme]

What do you mean "Had wrong layout" - In what way is it the wrong layout?

[Graeme]

This is because the linearLayout in the question is the "drawer" described in the method description - aka, the second child of the DrawerLayout

[Graeme]

@Jonik The important part is that the linearLayout is the "drawer" - aka, the second child of the DrawerLayout

[Armaan Stranger]

it had wrong layout referenced in closeDrawer(). and answer is accepted so i think i was right.

[ataulm]

@Graeme +1, answer is not clear. The parameter given to closeDrawer() should be the viewgroup that corresponds to the drawer portion of the drawerlayout.

[lmaooooo]

That is correct. I had the same issue, because I copied the code from the Google's example. So apparently they made an error there

[Rajesh]

Thanks for your answer it really helped me a lot.

[Ashish Tiwari]

This answer saved my life. Thank You

[Martin Nuc]

Same happened to me after customizing my drawer because they use lsit drawer in google but I used linear layout.

[Liangjun]

this is not working for me. I had this error: linearLayout is not a sliding drawer

[Ojonugwa Jude Ochalifu]

This "answer" is useless, am sorry.

[BusyProgrammer]

Please edit your answer so that the code shows up as code.

[Samuel Owino]

this is a poorly done answer, @piyush please provide more precise answer
