Hi,
I am trying to write a simple application that creates a new tab. The
view structure is:
FrameLayout
-- TabHost
-------TabWidget
-------FrameLayout
The code is shown below:
public class P4Main extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override
public void onStart() {
super.onStart();
//We can try to add tabs and related views programmatically here
createAdditionalViews();
}
private void createAdditionalViews()
{
/*
TextView tv = new TextView(this);
tv.setText("Test view");
*/
TabHost thRoot = new TabHost(this);
TabWidget tabs = new TabWidget(this);
tabs.setId(android.R.id.tabs);
thRoot.addView(tabs);
FrameLayout tabcontent = new FrameLayout(this);
tabcontent.setId(android.R.id.tabcontent);
thRoot.addView(tabcontent);
thRoot.setup();
TabHost.TabSpec tabSetup = thRoot.newTabSpec("Setup");
tabSetup.setIndicator("Setup");
TextView tv1 = new TextView(this);
tv1.setText("This is the Setup tag.");
tabSetup.setContent(tv1.getId());
thRoot.addTab(tabSetup);
thRoot.setCurrentTabByTag("Setup");
ViewGroup.LayoutParams lp = new ViewGroup.LayoutParams
(ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.FILL_PARENT);
this.addContentView(thRoot, lp);
}
}
When I run it, it crashes at the line:
tabSetup.setContent(tv1.getId());
The debug call stack is as below:
ActivityThread.performLaunchActivity(ActivityThread$ActivityRecord)
line: 2266
ActivityThread.handleLaunchActivity(ActivityThread$ActivityRecord)
line: 2284
ActivityThread.access$1800(ActivityThread, ActivityThread
$ActivityRecord) line: 112
ActivityThread$H.handleMessage(Message) line: 1692
ActivityThread$H(Handler).dispatchMessage(Message) line: 99
Looper.loop() line: 123
ActivityThread.main(String[]) line: 3948
Method.invokeNative(Object, Object[], Class, Class[], Class, int,
boolean) line: not available [native method]
Method.invoke(Object, Object...) line: 521
ZygoteInit$MethodAndArgsCaller.run() line: 782
ZygoteInit.main(String[]) line: 540
NativeStart.main(String[]) line: not available [native method]
What am I missing/doing wrong?
Thanks,
