I'm seeing a strange behavior with a TabHost that creates a tab as a
new Intent. Is this just the way it is, and I'll have to work with
it?
The tab intent is created twice, instead of once. I'm on the
emulator, sdk 1.1.
The behavior to get this is:
Launch tab host app, and note the state (call it state A)
Hit Home
Launch tab host app again, and note the state (state B)
Hit back button
The app should exit, but instead, State A is displayed, which is
actually the first tab Intent created.
I think this flow only happens on the first launch, but I may be
wrong.
I'm thinking I can fix my "displaying old state" issue by rendering
out of the database, but it doesn't change that it seems like two
intents are created, when only one should be. My best case here is
that the user will think hitting the back button "didn't work" the
first time, and will hit it again...
Here's the "hello world" code to see this. Launch it once, hit home,
launch it again, and note the milliseconds it's displaying. Hit back
button. Woh, it's still displaying the app, but the milliseconds have
changed. It's actually displaying the tab the first time it was
created.
// tab host:
public class TabHostTest extends TabActivity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TabHost th = getTabHost();
th.addTab(th.newTabSpec("mytab")
.setIndicator("I'm a tab")
.setContent(new Intent(this,
cc.thtest.TabOne.class)
.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)));
}}
//tab:
public class TabOne extends Activity {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tab_one_content);
TextView tv = (TextView) findViewById(R.id.txt);
tv.setText( "Cur time Is : " + System.currentTimeMillis() );
}}
// xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:id="@+id/txt"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:text="No data"/>
</LinearLayout>
