Figured I might as well talk about the solution I came up with in-case
someone comes to this thread with the same ideas I was
Eventually went with a workaround of having a base layout with 3 frame
layouts...
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<FrameLayout
android:id="@+id/fragment_sb"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<FrameLayout
android:id="@+id/fragment_local"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<FrameLayout
android:id="@+id/fragment_rest"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1"/>
</LinearLayout>
Then in my activity with the tabs I made a custom TabListener that
handled the changes between. The code I used is below (I'm using
actionbarsherlock so it'll look slightly different than the normal
stuff)
public class TabActivity extends FragmentActivity {
Fragment1 fragment1;
Fragment2 fragment2;
Fragment3 fragment3;
Fragment4 fragment4;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_layout);
final ActionBar bar = getSupportActionBar();
bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
bar.setDisplayShowTitleEnabled(true);
bar.setDisplayShowHomeEnabled(false);
bar.setTitle("Title");
bar.addTab(bar.newTab()
.setIcon(R.drawable.ic_list_tab_selected)
.setTabListener(new ListTabListener(this)));
bar.addTab(bar.newTab()
.setIcon(R.drawable.ic_map_tab_selected)
.setTabListener(new MapTabListener(this)));
if (savedInstanceState != null) {
bar.setSelectedNavigationItem(savedInstanceState.getInt("tab", 0));
}
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
outState.putInt("tab",
getSupportActionBar().getSelectedNavigationIndex());
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.test_menu, menu);
return super.onCreateOptionsMenu(menu);
}
public static class ListTabListener implements
ActionBar.TabListener {
private static final String fragment1Tag = "fragment1_tag";
private static final String fragment2Tag = "fragment2_tag";
private static final String fragment3Tag = "fragment3_tag";
private FragmentActivity activity;
private Fragment1 fragment1;
private Fragment2 fragment2;
private Fragment3 fragment3;
public ListTabListener(FragmentActivity activity) {
this.activity = activity;
FragmentTransaction ft =
activity.getSupportFragmentManager().beginTransaction();
fragment1 = (Fragment1)
activity.getSupportFragmentManager().findFragmentByTag(fragment1Tag);
if (fragment1 != null && !fragment1.isDetached()) {
ft.detach(fragment1);
}
fragment2 = (Fragment2)
activity.getSupportFragmentManager().findFragmentByTag(fragment1Tag);
if (fragment2 != null && !fragment2.isDetached()) {
ft.detach(fragment2);
}
fragment3 = (Fragment3)
activity.getSupportFragmentManager().findFragmentByTag(fragment1Tag);
if (fragment3 != null && !fragment3.isDetached()) {
ft.detach(fragment3);
}
ft.commit();
}
@Override
public void onTabReselected(Tab tab, FragmentTransaction nullFt)
{
//Reselected don't do anything
}
@Override
public void onTabSelected(Tab tab, FragmentTransaction nullFt) {
FragmentTransaction ft =
activity.getSupportFragmentManager().beginTransaction();
if(fragment1 == null) {
fragment1 = new Fragment1();
ft.add(R.id.fragment_sb, fragment1,
fragment1Tag);
} else {
ft.attach(fragment1);
}
if(fragment2 == null) {
fragment2 = new Fragment2();
ft.add(R.id.fragment_local, fragment2,
fragment2Tag);
} else {
ft.attach(fragment2);
}
if(fragment3 == null) {
fragment3 = new Fragment3();
ft.add(R.id.fragment_rest, fragment3,
fragment3Tag);
} else {
ft.attach(fragment3);
}
ft.commit();
}
@Override
public void onTabUnselected(Tab tab, FragmentTransaction nullFt)
{
FragmentTransaction ft =
activity.getSupportFragmentManager().beginTransaction();
if(fragment1 != null)
ft.detach(fragment1);
if(fragment2 != null)
ft.detach(fragment2);
if(fragment3 != null)
ft.detach(fragment3);
ft.commit();
}
}
public static class MapTabListener implements
ActionBar.TabListener {
private static final String fragment4Tag = "fragment4_tag";
private FragmentActivity activity;
private Fragment4 fragment4;
public MapTabListener(FragmentActivity activity) {
this.activity = activity;
FragmentTransaction ft =
activity.getSupportFragmentManager().beginTransaction();
fragment4 = (Fragment4)
activity.getSupportFragmentManager().findFragmentByTag(fragment4Tag);
if (fragment4 != null && !fragment4.isDetached()) {
ft.detach(fragment4);
}
ft.commit();
}
@Override
public void onTabReselected(Tab tab, FragmentTransaction nullFt)
{
//Reselected don't do anything
}
@Override
public void onTabSelected(Tab tab, FragmentTransaction nullFt) {
FragmentTransaction ft =
activity.getSupportFragmentManager().beginTransaction();
if(fragment4 == null) {
fragment4 = new Fragment4();
ft.add(R.id.fragment_rest, fragment4,
fragment4Tag);
} else {
ft.attach(fragment4);
}
ft.commit();
}
@Override
public void onTabUnselected(Tab tab, FragmentTransaction nullFt)
{
FragmentTransaction ft =
activity.getSupportFragmentManager().beginTransaction();
if(fragment4 != null)
ft.detach(fragment4);
ft.commit();
}
}
}
If anyone sees any flaws or has a suggestion for improvement please
point it out
