Tabs Using Fragments On Android, But Inside Another Layout

I'm creating android app that has table layout for the main activity, and that part works perfectly... Now, the idea was to add another part of an app below the existing components

Solution 1:

Ideally this would be done using nested Fragments, but Android doesn't support that yet. That leaves the deprecated ActivityGroup class. You'll need a top level activity that extends ActivityGroup and launches the two activities.

Here is how you launch the activities and get their views:

finalWindoww= getLocalActivityManager().startActivity(myTag, myIntent);
finalViewwd= w != null ? w.getDecorView() : null;
if (  null != wd ) {
    wd.setVisibility(View.VISIBLE);
    wd.setFocusableInTouchMode(true);
}
// TODO: Attach wd to a ViewGroup.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Edit: Below is a more complete solution.

This is the layout for the top level activity:

<?xml version="1.0" encoding="utf-8"?><LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:id="@+id/root_layout"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical" 
    ></LinearLayout>

Here is the top level class:

publicclassEmbeddedActivityParentextendsActivityGroup {

    private LinearLayout    mRootLayout;

    @OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.main);

         mRootLayout = (LinearLayout) findViewById(R.id.root_layout);

         // Add embedded status activity.
         embedActivity("StatusColumn", newIntent(this, StatusActivity.class));

         // Add embedded work activity.
         embedActivity("WorkArea", newIntent(this, MainActivity.class));
    }

    privatevoidembedActivity(String myTag, Intent launchIntent) {
         finalWindoww= getLocalActivityManager().startActivity(myTag, launchIntent);
         finalViewwd= w != null ? w.getDecorView() : null;
         if (  null != wd ) {
             wd.setVisibility(View.VISIBLE);
             wd.setFocusableInTouchMode(true);

             mRootLayout.addView(wd);
         }
    }
}

You can add as many embedded activities as you want. You can even nest embedded activities, but be aware that performance could become a factor. We use this to support a dynamic status column.

Personally, I think there is still a use for the ActivityGroup and hope that Gooogle changes their mind about deprecating it.
