I would like to implement a swipe views into my Sherlock fragments with the drawer menu. I did it and it seems works fine, owever, there is a minor issue that i can't figure out.
So let's begin with some pices of my code:
MainActivity
public class MainActivity extends SherlockFragmentActivity {
// Declare Variable
DrawerLayout mDrawerLayout;
ListView mDrawerList;
ActionBarDrawerToggle mDrawerToggle;
MenuListAdapter mMenuAdapter;
String[] title;
String[] subtitle;
int[] icon;
Fragment fragment1 = new TestFragment();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.drawer_main);
// Generate title
title = new String[] { "Test title" };
// Generate subtitle
subtitle = new String[] { "Test subtitle" };
// Generate icon
icon = new int[] { R.drawable.action_about };
// Locate DrawerLayout in drawer_main.xml
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
// Locate ListView in drawer_main.xml
mDrawerList = (ListView) findViewById(R.id.left_drawer);
// Set a custom shadow that overlays the main content when the drawer
// opens
mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow,
GravityCompat.START);
// Pass results to MenuListAdapter Class
mMenuAdapter = new MenuListAdapter(this, title, subtitle, icon);
// Set the MenuListAdapter to the ListView
mDrawerList.setAdapter(mMenuAdapter);
// Capture button clicks on side menu
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
// Enable ActionBar app icon to behave as action to toggle nav drawer
getSupportActionBar().setHomeButtonEnabled(true);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
// ActionBarDrawerToggle ties together the the proper interactions
// between the sliding drawer and the action bar app icon
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
R.drawable.ic_drawer, R.string.drawer_open,
R.string.drawer_close) {
public void onDrawerClosed(View view) {
// TODO Auto-generated method stub
super.onDrawerClosed(view);
}
public void onDrawerOpened(View drawerView) {
// TODO Auto-generated method stub
super.onDrawerOpened(drawerView);
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
if (savedInstanceState == null) {
selectItem(0);
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getSupportMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
if (mDrawerLayout.isDrawerOpen(mDrawerList)) {
mDrawerLayout.closeDrawer(mDrawerList);
} else {
mDrawerLayout.openDrawer(mDrawerList);
}
}
return super.onOptionsItemSelected(item);
}
// The click listener for ListView in the navigation drawer
private class DrawerItemClickListener implements
ListView.OnItemClickListener {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
selectItem(position);
}
}
private void selectItem(int position) {
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
// Locate Position
switch (position) {
case 0:
ft.replace(R.id.content_frame, fragment1);
break;
ft.commit();
mDrawerList.setItemChecked(position, true);
// Close drawer
mDrawerLayout.closeDrawer(mDrawerList);
}
@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 toggles
mDrawerToggle.onConfigurationChanged(newConfig);
}
}
TestFragment:
public class TestFragment extends SherlockFragment {
ViewPager mViewPager;
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.test, container, false);
mViewPager = (ViewPager) rootView.findViewById(R.id.viewpager);
PagerTabStrip pagerTabStrip = (PagerTabStrip) rootView.findViewById(R.id.pagerTabStrip);
testAdapter titleAdapter = new testAdapter(getFragmentManager());
mViewPager.setAdapter(titleAdapter);
mViewPager.setCurrentItem(0);
return rootView;
}
}
testAdapter
public class testAdapter extends FragmentPagerAdapter {
private String titles[] = new String[]{"View1","View2"};
private Fragment frags[] = new Fragment[titles.length];
public systemAdapter(FragmentManager fm) {
super(fm);
frags[0] = new testSwipe1();
frags[1] = new testSwipe2();
}
@Override
public CharSequence getPageTitle (int position){
Log.v("TitleAdapter - getPageTitle=", titles[position]);
return titles[position];
}
@Override
public Fragment getItem(int position) {
Log.v("TitleAdapter - getItem=", String.valueOf(position));
return frags[position];
}
@Override
public int getCount() {
return frags.length;
}
testSwipe1 and testSwipe2 are the same:
public class testSwipe1 extends SherlockFragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View rootView = inflater.inflate(R.layout.testswipe_layout, container, false);
ImageButton testImage = (ImageButton) rootView.findViewById(R.id.test);
//todo function image
return rootView;
}
}
Ok, the drawer works fine and if i tap on "test title" it inflate the layout with the swipe and i can see the image in the 2 test swipe views. Owever, if i open back the drawer and tap again on "test title" i can see the swipe views without the images on my swipe fragment layout. If i put the device in landscape and back to portrait, the image on my swipe fragments come back! open drawer -> tap again on test title -> images disappear.... -> landscaper -> portrait -> image back.
The layouts defined are standard for drawer and swipeviews. inside the swipeviews fragments layout there is only an imageview. So the issue must be in the java part but i can't figure out where. Any helps?
