문제
I need to implement tabs in my project.i have a layout, in which i have two tabs and a button. For two tabs,I have two activities and button calling different activity. the thing is I am showing result of button on first tab. i.e tab0 is active on tab0 event and on button click event. And am able to change the tab events using tabHost.setOnTabChangedListener
, but now what i further want is, say suppose i click on button so now button view is displaying but again if i click on tab0, tab0 activity should be displayed.
i used onClick but after using this my TabChangeListner not works.
would you suggest solution for my problem.
Thanks.
Below is my code that is working fine :
public class TabLayoutUsingTabChangeEventActivity extends TabActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final TabHost tabHost = (TabHost)findViewById(android.R.id.tabhost);
final TabHost.TabSpec sp1 = tabHost.newTabSpec("TAB1");
TabHost.TabSpec sp2 = tabHost.newTabSpec("TAB2");
//Creating First Tab
Intent intent1 = new Intent(this, Tab1Activity.class);
sp1.setIndicator("TAB1").setContent(intent1);
tabHost.addTab(sp1);
//Creating Second Tab
Intent intent2 = new Intent(this, Tab2Activity.class);
sp2.setIndicator("TAB2").setContent(intent2);
tabHost.addTab(sp2);
//Tab Changed Event
tabHost.setOnTabChangedListener(new OnTabChangeListener(){
@Override
public void onTabChanged(String tabId) {
Log.i("TabId :", tabId);
if(tabId.equals("TAB2")){
Log.i("TAB1", "TAB1 Changed");
Intent intent1 = new Intent().setClass(getApplicationContext(), Tab1Activity.class);
sp1.setIndicator("TAB1").setContent(intent1);
tabHost.setCurrentTab(0);
}
}
});
Button addNewButton = (Button)findViewById(R.id.add_new_ticket_btn);
addNewButton.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
Intent in = new Intent().setClass(getApplicationContext(), AddNewTicketActivity.class);
sp1.setContent(in);
tabHost.setCurrentTab(0);
//startActivity(in);
}
});
}
}

You need to use AvtivityGroup to open new activities in the same tab.
Here is the complete example.
