Ich versuche, eine Registerkartenansicht zu erstellen, mit der nach ID zu einer anderen Inhaltsansicht gewechselt wird. Hier ist meintab activity:

<code>public class TabViews extends TabActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.tabviews);
    TabHost tabHost = getTabHost();

    LayoutInflater.from(this).inflate(R.layout.tabviews, tabHost.getTabContentView(), true);

    tabHost.addTab(tabHost.newTabSpec("apples")
            .setIndicator("Apples")
            .setContent(R.id.apples));
    tabHost.addTab(tabHost.newTabSpec("events")
            .setIndicator("Events")
            .setContent(R.id.events));
    tabHost.addTab(tabHost.newTabSpec("attend")
            .setIndicator("Attending")
            .setContent(R.id.attend));
}
}
</code>

Hier ist das tabviews xml Layout.

<code><?xml version="1.0" encoding="utf-8"?>

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

<TextView android:id="@+id/view1"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:text="test"/>   

<TextView android:id="@+id/view2"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:text="test"/>

<TextView android:id="@+id/view3"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:text="test"/>

</FrameLayout>
</code>

Ich habe drei andere XML-Layouts besucht, Ereignisse und Äpfel, auf die ich zugreifen kann, indem ich eine neue Absicht erzeuge, die aufruftstartActivity auf diesemIntent.

Ich bin mir nicht sicher, was ich falsch mache. Ich bin ein bisschen neu darin.

UPDATE: Ok, also ... ich meine ... ich möchte die Aktivität mit Hilfe von Registerkarten ändern. Hier ist, wie ich es gemacht habe. Die Antwort bestand darin, den Inhalt mit Intent festzulegen, anstatt mit tabHost.addTab (tabHost.newTabSpec ("tab2") .setIndicator ("Something") .setContent (new Intent (this, myActivity.class));

Vielen Dank an alle, die mitgeholfen haben. Es brachte mich dazu, über mehr Optionen nachzudenken.

Prost, Joe.
