Android: TabHost without TabActivity

Question

I want to create tabs without extending TabActivity. (The reason is that TabActivity cannot handle a custom titlebar as it seems). I have

Answer 1

Before calling tabHost.setup(mLocalActivityManager); you need to add this line.

mlam.dispatchCreate(savedInstanceState);
tabHost.setup(mlam );

similarly, you need to add for onResume,

mlam.dispatchResume(); 

onPause(),

 mlam.dispatchPause(isFinishing());

public class ScoreboardActivity extends Activity {
    LocalActivityManager mlam;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_scoreboard);
        mlam = new LocalActivityManager(this, false);
        mlam.dispatchCreate(savedInstanceState);
        TabHost th = (TabHost) findViewById(android.R.id.tabhost);
        th.setup(mlam);
        th.addTab(th.newTabSpec("Numpad").setIndicator("Numpad").setContent(R.id.tab1));
        th.addTab(th.newTabSpec("CardCount").setIndicator("CardCount").setContent(R.id.tab2));
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_scoreboard, menu);
        return true;


    }
    @Override
    protected void onResume(){
        super.onResume();
        mlam.dispatchResume();
    }

    @Override
    protected void onPause(){
        super.onPause();
        mlam.dispatchPause(isFinishing());
    }

}

Please consider using Views as the contents of your tabs. Not only will this result in less code, less consumed heap space, less consumed stack space, and lower CPU utilization, it will also get you past this problem. Here are two examples showing this technique.

Answer 4

Design considerations notwithstanding, the following does not work at all, and the API seems to indicate that setContent(Intent i) is valid. This works when the activity extends TabActivity, however, extending Activity and adding setup() call results in an exception at android.widget.TabHost$IntentContentStrategy.getContentView(TabHost.java:649)

Funny thing is, the LogCat suggests I forgot to call setup()

mTabHost = (TabHost) findViewById(android.R.id.tabhost);
mTabHost.setup();

Intent tab1Intent = new Intent(this, ActivityOne.class);
Button tab1View = new Button(this);
tab1View.setText("Activity 1");
  mTabHost.addTab(mTabHost.newTabSpec("tab_1").setIndicator(tab1View).setContent(tab1Intent));
