FragmentTabHost how to get the view in the current tab control ah.

FragmentTabHost

I have several tab, has the same layout in a TextView, now I want to get in the View Tab currently in this TextView.

I

 
TextView tv = (TextView) mTabHost.getCurrentView () findViewById (R.id.tvLeftUpValue);. 

Obtained TextView empty.

Or can get the current instance of the corresponding Class View also line ah.
For example

 FragmentPage_idle idle = (FragmentPage_idle) mTabHost.getCurrentView () getClass ();. 

New, first time Android, sorry, forgive me

Directly to the original fine. This is not to understand the principles of fate

 
switch (mTabHost.getCurrentTab ()) {
case 0: {/ / 
TextView tv = (TextView) findViewById (R.id.tvLeftUpValue); 
tv.setText (ds.getDataItemS ("x00020001")); 
} 
}
