Double ListView в Android FrameLayout

Question

У меня есть один Drawerlayout, когда я запускаю приложение, данные в MainActivity с pagemain_layout(frame_container)... Все хорошо. Но когда я нажимаю на элемент в раскрывающемся ящике, появляется двойной список в pagemain_layout.

Пожалуйста... Дайте мне решение или отредактируйте мой код.

Большое спасибо!

Код MainActivity

public class MainActivity extends Activity {

    private DrawerLayout mDrawerLayout;
    private ListView mListDrawer;
    private ActionBarDrawerToggle mDrawerToggle;
    private CharSequence mDrawerTitle;
    private CharSequence mTitle;
    private String[] navMenuTitles;
    NavDrawerItemsAdapter adapterTest;
    FragmentManager fragmentManager;
    ListView lvItemLayoutMain;
    ProgressDialog pDialog;

            break;

        default:
            break;
        }

        if (fragment != null) {
            fragmentManager = getFragmentManager();
            transaction.replace(R.id.frame_container, fragment).commit();
            transaction.addToBackStack(null);
            transaction.commit();
            // update selected item and title, then close the drawer
            mListDrawer.setItemChecked(position, true);
            mListDrawer.setSelection(position);
            setTitle(navMenuTitles[position]);
            mDrawerLayout.closeDrawer(mListDrawer);
        } else {
            Log.e("MainActivity", "Error in creating fragment");
        }
    }

    private class SlideMenuClickListener implements
            ListView.OnItemClickListener {
        @Override

                long id) {
            // display view for selected nav drawer item
            displayView(position);
        }
    }

    @Override
    public void setTitle(CharSequence title) {
        mTitle = title;
        getActionBar().setTitle(title);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // toggle nav drawer on selecting action bar app icon/title
        if (mDrawerToggle.onOptionsItemSelected(item)) {
            return true;
        }
        // Handle action bar actions click
        switch (item.getItemId()) {
        case R.id.action_settings:
            return true;
        default:
            return super.onOptionsItemSelected(item);
        }
    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        // Sync the toggle state after onRestoreInstanceState has occurred.
        mDrawerToggle.syncState();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        super.onConfigurationChanged(newConfig);
        // Pass any configuration change to the drawer toggls
        mDrawerToggle.onConfigurationChanged(newConfig);
    }

    class LoadData extends AsyncTask<Void, Void, Vector<ArrayList<String>>> {
        String Url = "http://ued.vn/rss/cong-tac-sinh-vien.rss";
        Vector<ArrayList<String>> data = new Vector<ArrayList<String>>();
        final String KEYGROUP = "Thông báo";

        @Override
        protected void onPreExecute() {
            pDialog = ProgressDialog.show(MainActivity.this, "", "Loading...");
            mListTitle = new ArrayList<String>();
            mListURL = new ArrayList<String>();
            super.onPreExecute();
        }

        @Override
        protected Vector<ArrayList<String>> doInBackground(Void... params) {
            data = Utils.getDataNews(Url, KEYGROUP);
            return data;
        }

        @Override
        protected void onPostExecute(Vector<ArrayList<String>> result) {
            if (data != null) {
                pDialog.dismiss();
                mListTitle = data.get(0);
                NewsHotAdapter adapter = new NewsHotAdapter(MainActivity.this,
                        R.layout.item_layout, mListTitle);
                lvItemLayoutMain.setAdapter(adapter);
            }
            super.onPostExecute(result);
        }

    }

}

И код в pagemain_layout.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
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >

        <ListView
            android:id="@+id/list_item_main"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            android:choiceMode="singleChoice"
            android:dividerHeight="1dp" />
    </FrameLayout>

    <ListView
        android:id="@+id/list_slidermenu"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="@color/list_background"
        android:choiceMode="singleChoice"
        android:divider="@color/list_divider"
        android:dividerHeight="1dp"
        android:listSelector="@drawable/list_selector" />

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

Проблема здесь!

Answer 1

Пожалуйста, удалите android:layout_gravity="start" определено в Listview FrameLayout в XML. Ваш код должен быть следующим,

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

        <ListView
            android:id="@+id/list_item_main"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:choiceMode="singleChoice"
            android:dividerHeight="1dp" />
    </FrameLayout>

    <ListView
        android:id="@+id/list_slidermenu"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="@color/list_background"
        android:choiceMode="singleChoice"
        android:divider="@color/list_divider"
        android:dividerHeight="1dp"
        android:listSelector="@drawable/list_selector" />

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

Попробуйте этот код и дайте мне знать.
