Android : launching diff activities under TabWidget -

-

I am trying to launch activities under each tab. I have tried with the following code 

  Public class Tab_Proj1 TabActivity {TabHost mTabHost; Crate on Public Zero (Bundle Saved Instantstate) {Super. Secret (Saved Instantstate); SetContentView (R.layout.main); Last Reference Reference = getApplicationContext (); // mTabHost = (TabHost) this.findViewById (R.id.); MTabHost = getTabHost (); MTabHost.setup (); MTabHost.addTab (mTabHost.newTabSpec ("tab_test4") .setIndicator ("contact") .setContent (new intent (.) SetClass (context, Tab1Activity.class)));

Tab1Activity ListActivity is expanding and I am getting the following error: 

  01-25 11: 57: 07.352: error / androidtime (9 52) ): Uncouted handler: Due to the exception of the main thread, 01-25 11: 57: 07.382: Error / Android Runtime (9 52): java.lang.RuntimeException: Unable to launch activity ComponentInfo {com.android.app .Tab_Proj1 / com.android app.Tab_Proj1.Tab_Proj1}: java.lang.RuntimeException: 57 :: 07.382: Error / AndroidRuntime (952): tab content because ID +2131034148 is not visible with November 01-25 Could not create android.app.ActivityThread.performLaunchActivity (ActivityThread.java .2626) 01-25 Nov: 57: 07.382: Error / AndroidRuntime (952): 57 :: 07.382: Error / AndroidRuntime android.

oracle - The fastest way to check if some records in a database table? -

-
I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
