Fragment seems to inflate wrong view - android-fragments

Question

I'm currently trying to program an Android Launcher with Fragments but I have problems with the Views on the Fragments.
I have a Dock-Fragment with a Dock-Controller which allow the user to change fragments, such as apps menu, settings fragment etc. The Dock is displayed on the buttom of the display, the Fragments(apps menu, settings fragment) should be displayed above the Dock.
The problem is, that the apps menu is not shown in its associated Fragment but rather in the Dock Fragment behind the dock icons,... So I guess, the app menu fragment gets the wrong view in its onCreateView()-Method, but I don't get why.
This is the code of the MainActivity that extends from FragmentActivity. I add the fragments to the manager.
private void addDockToManager() {
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.add(dbConnection.getLayout(DOCK_TAG), dockController.getFragment(), DOCK_TAG);
ft.commit();
}
private void addPluginsToManager() {
FragmentManager fm = null;
FragmentTransaction ft = null;
for(String key : controllerMap.keySet()) {
fm = getSupportFragmentManager();
ft = fm.beginTransaction();
FrameController controller = null;
if ((controller = controllerMap.get(key)) != null) {
ft.add(dbConnection.getLayout(key), controller.getFragment(), key);
if (key.equals(standardFrame))
ft.addToBackStack(key);
}
ft.commit();
fm.executePendingTransactions();
}
fm = getSupportFragmentManager();
ft = fm.beginTransaction();
for(String key : controllerMap.keySet()) {
if (controllerMap.get(key) != null && !key.equals(standardFrame)) {
ft.hide(fm.findFragmentByTag(key));
}
}
ft.commit();
}
The layouts are hardcoded at the moment in dbConnection:
public int getLayout(String name) {
int layout = -1;
switch(name) {
case "app_menu" : layout = R.id.fl_app_menu;
case "settings" : layout = R.id.fl_settings;
case "dock" : layout = R.id.fl_dock;
}
return layout;
}
The MainActivity's xml looks like that:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/rl_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.activity.MainActivity"
tools:ignore="MergeRootFrame" >
<FrameLayout
android:id="#+id/fl_settings"
android:layout_width="match_parent"
android:layout_height="400dp"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_above="#+id/fl_dock"
android:background="#00ffffff" >
</FrameLayout>
<FrameLayout
android:id="#+id/fl_app_menu"
android:layout_width="match_parent"
android:layout_height="400dp"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_above="#+id/fl_dock"
android:background="#00ffffff" >
</FrameLayout>
<FrameLayout
android:id="#+id/fl_dock"
android:layout_width="match_parent"
android:layout_height="70dp"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true" >
</FrameLayout>
</RelativeLayout>
The xml of the apps menu is a gridview and looks like that:
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/gv_apps"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:numColumns="6"
android:gravity="center"
android:columnWidth="50dp"
android:stretchMode="columnWidth" >
</GridView>
The App Fragment looks like that:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup group,
Bundle savedInstanceState) {
view = inflater.inflate(R.layout.external_apps, group, false);
layout = (GridView) view.findViewById(R.id.gv_apps);
return view;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
GridViewAdapter gridViewAdapter = new GridViewAdapter((AppMenuController) myController, apps);
((GridView) layout).setAdapter(gridViewAdapter);
}
And the getView Method of the GridViewAdapter:
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView = new ImageView(controller.getMainActivity().getApplicationContext());
imageView.setImageDrawable(buttons.get(position).getIcon());
imageView.setLayoutParams(new GridView.LayoutParams(65, 65));
return imageView;
}
I hope what I mentioned is enough to resolve the problem. I am searching the web for hours but I found no solution.

Answer 1

It's a much simpler problem than that I think.
public int getLayout(String name) {
int layout = -1;
switch(name) {
case "app_menu" : layout = R.id.fl_app_menu;
case "settings" : layout = R.id.fl_settings;
case "dock" : layout = R.id.fl_dock;
}
return layout;
}
Should be:
public int getLayout(String name) {
int layout = -1;
switch(name) {
case "app_menu" :
layout = R.id.fl_app_menu;
break;
case "settings" :
layout = R.id.fl_settings;
break;
case "dock" :
layout = R.id.fl_dock;
break;
}
return layout;
}
Because switch-case structure is still essentially just an organized goto, and not actually an if-else structure, aka if you don't break out, then all cases will run sequentially.

Answer 2

I found the problem. And it was in a part of the code I never expected it to be.
The Dummy-Switch-Case in dbConnection caused it. Seemingly Strings aren't compared by value but rather by reference in such a Switch-Case. So it always chose the dock container layout to be associated with the app menu in the fragment manager,...
