I have a TabActivity with some tabs for user input. When the user is done with the input and presses the save button I proceed towards data saving. This is done by calling the method startDataTravershal() in each activity. I want to show a progressDialog when the button is pressed and dismiss it when the data save is done. however whatever I do the progressDialog is not showing.
my code :
public class HandHoldingTabUI extends TabActivity {
TabHost TabHostWindow;
TabSpec TabEntry;
TabSpec TabRectification;
TabSpec TabG26;
TabSpec TabU26;
TabSpec TabG27;
TabSpec TabBudget;
TabSpec TabBDC;
TabSpec TabTradeL;
TabSpec TabIncomeC;
TabSpec TabPCC;
TabSpec TabTAR;
TabSpec TabPNTA;
TabSpec TabPaperless;
TabSpec TabOthers;
Button btnSaveData = null;
ProgressDialog progressDialog = null;
public static HandHoldingTabUI context;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.handholding_tab_ui);
context=this;
UserDataHelper helper = new UserDataHelper(HandHoldingTabUI.this);
helper.deleteData("delete from "+UserDataHelper.tableMentorSurveyData);
helper.close();
init();
}
private void init() {
btnSaveData = (Button) findViewById(R.id.btnSaveData);
btnSaveData.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
progressDialog = ProgressDialog.show(HandHoldingTabUI.this, "",
"Loading. Please wait...");
HandHoldingTabUI.this.runOnUiThread(new Runnable() {
@Override
public void run() {
saveData();
progressDialog.dismiss();
}
});
}
});
TabHostWindow = (TabHost)findViewById(android.R.id.tabhost);
createTab(TabEntry,"Entry","Entry", Entry.class); //Entry
createTab(TabRectification,"Rectification","Rectification", Rectification.class); // Rectification
createTab(TabG26,"Generation of form 26","Generation of form 26", G26.class); //Generation of form 26

createTab(TabBudget,"Budget (Form 36)","Budget (Form 36)", Budget.class); //Budget (Form 36)
createTab(TabBDC,"Birth and Death Certificate","Birth and Death Certificate", BDC.class); //Birth and Death Certificate
createTab(TabTradeL,"Trade license","Trade license", TradeL.class); //Trade license

I have tried these solutions but they were of no help :

Show a progress dialog in android tab layout
android how to put progressdialog in TabActivity
i would greatly appreciate any help regarding this matter.
thanks,best regards.
EDIT: according to the comment i have tried to do this :-
AsyncTask task = new AsyncTask() {
@Override
protected Object doInBackground(Object[] params) {
progressDialog = ProgressDialog.show(HandHoldingTabUI.this, "",
"Loading. Please wait...");
saveData();
return null;
}
@Override
protected void onPostExecute(Object o) {
progressDialog.dismiss();
proceedToShowDraft();
}
};
this is written on the onClick() of the button. but now when i click the button,nothing happens.
