How to assign activities as tab content?

Question

I found this custom TabWidget layout on the internet. The problem is, I dont know how to insert content into the tabs. Can someone help on this? Say I have activity1, activity2 and activity3. Heres the code:

public class MainActivity extends Activity {
private TabHost mTabHost;

private void setupTabHost() {
    mTabHost = (TabHost) findViewById(android.R.id.tabhost);
    mTabHost.setup();
}

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    setupTabHost();
    mTabHost.getTabWidget().setDividerDrawable(R.drawable.tab_divider);

    setupTab(new TextView(this), "EASY");
    setupTab(new TextView(this), "MEDIUM");
    setupTab(new TextView(this), "INTENSE");
}

private void setupTab(final View view, final String tag) {
    View tabview = createTabView(mTabHost.getContext(), tag);

    TabSpec setContent = mTabHost.newTabSpec(tag).setIndicator(tabview).setContent(new TabContentFactory() {
        public View createTabContent(String tag) {return view;}
    });
    mTabHost.addTab(setContent);

}

private static View createTabView(final Context context, final String text) {
    View view = LayoutInflater.from(context).inflate(R.layout.tabs_bg, null);
    TextView tv = (TextView) view.findViewById(R.id.tabsText);
    tv.setText(text);
    return view;
}
}

Answer 1

You put content into activities by making their own files, declaring them in manifest and putting in their onCreate the setContentView(R.layout.activitylayout);. And if the content is static, it is wholely described in the appropriate layout.

Ok, understood. then return as view here public View createTabContent(String tag) {return view;} that layout that you want to place there. Some listViewOfMyPictures or things.

Try looking at the docs for TabHost.TabSpec, in particular setContent(Intent intent).

Create intents such as Intent tabIntentA = new Intent(this, SomeActivity.class); and pass them to the setContent(...) method.

EDIT:

Look at section 6 of the Tab Layout tutorial - particularly this code...

Intent intent;  // Reusable Intent for each tab

// Create an Intent to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, ArtistsActivity.class);

// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("artists").setIndicator("Artists",
                    res.getDrawable(R.drawable.ic_tab_artists))
                    .setContent(intent);
tabHost.addTab(spec);

You'd probably be better off following that tutorial anyway rather than the code you posted in your question.

Answer 3

Create an intent for the specific Activity, and add the intent via "setContent" to the tabSpec, instead of where you currently create a TabContentFactory - like so (copy/pasted from the Hello Tabwidget tutorial in the Android Dev Guide):

Intent intent;  // Reusable Intent for each tab

// Create an Intent to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, ArtistsActivity.class);

// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("artists").setIndicator("Artists",
                  res.getDrawable(R.drawable.ic_tab_artists))
              .setContent(intent);
tabHost.addTab(spec);

I too faced the same problem and solved it by modifying the code as given below.

setupTab1(new TextView(this), "MEDIUM");
setupTab2(new TextView(this), "INTENSE");


private void setupTab1(final View view, final String tag) {

View tabview = createTabView(mTabHost.getContext(), string);

Intent intent1 = new Intent().setClass(this, DummyActivity1.class);
TabSpec tab1 = mTabHost
    .newTabSpec("TAB1")
    .setIndicator(tabview)
    .setContent(intent1);

mTabHost.addTab(tab1);

}

private void setupTab2(final View view, final String tag) {
View tabview = createTabView(mTabHost.getContext(), string);

Intent intent2 = new Intent().setClass(this, DummyActivity2.class);
TabSpec tab2 = mTabHost
    .newTabSpec("TAB2")
    .setIndicator(tabview)
    .setContent(intent2);

mTabHost.addTab(tab2);

}

Previously we had setupTab() method for all Tabview. Now we have different setupTab() methods with different activity.

It worked for me .. ! Hope this may help you.
