Example of using Android tabs with Views instead of Activities?
The Android Developers TabWidget tutorial says the following:
"You can implement your tab content in one of two ways: use the tabs to swap Views within the same Activity, or use the tabs to change between entirely separate activities."
The tutorial goes on to demonstrate how you can use tabs with separate Activities. I have been unable to find an example of using tabs with different Views within the same Activity. I would rather not re-invent this particular wheel, so I am hoping someone here knows how this is done and can clue me in. Thanks!
I think in the .setContent method of each tab you pass in the view you wish to use:
TabHost.TabSpec spec1 = tabs.newTabSpec("tag1");
spec1.setContent(R.id.AnalogClock01);
spec1.setIndicator("Analog Clock");
Here's an example I found awhile back:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TabHost android:id="@+id/TabHost01" android:layout_width="wrap_content" android:layout_height="wrap_content">
<TabWidget android:id="@android:id/tabs" android:layout_width="wrap_content" android:layout_height="wrap_content" />
<FrameLayout android:id="@android:id/tabcontent" android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingTop="65px">
<AnalogClock android:id="@+id/AnalogClock01" android:layout_width="wrap_content" android:layout_height="wrap_content"></AnalogClock>
<DigitalClock android:text="DigitalClock01" android:id="@+id/DigitalClock01" android:layout_width="wrap_content" android:layout_height="wrap_content"></DigitalClock>
</FrameLayout>
</TabHost>
</LinearLayout>
And the Java code for this example is as follows:
import android.app.Activity;
import android.os.Bundle;
import android.widget.TabHost;
public class tabexample extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TabHost tabs = (TabHost)findViewById(R.id.TabHost01);
tabs.setup();
TabHost.TabSpec spec1 = tabs.newTabSpec("tag1");
spec1.setContent(R.id.AnalogClock01);
spec1.setIndicator("Analog Clock");
tabs.addTab(spec1);
TabHost.TabSpec spec2 = tabs.newTabSpec("tag2");
spec2.setContent(R.id.DigitalClock01);
spec2.setIndicator("Digital Clock");
tabs.addTab(spec2);
}
}
我用这个，对我来说很好。http://www.codeproject.com/Articles/107693/Tabbed-Applications-in-Android
