How to retrieve my data from database into checkbox list view type?

I'm trying to retrieve my data from database into checkbox list view, but I'm unable to do so. Below is the code that I'm already using to retrieve data from database into list view. But what I want is to retrieve into checkbox list view type so that I can check it. How can I do that?
public class StudentDetailActivity extends Activity implements OnClickListener, OnItemClickListener {
private ListView uGraduateNamesListView;
private Button addNewUndergraduateButton;
private ListAdapter uGraduateListAdapter;
private ArrayList<UndergraduateDetailsPojo> pojoArrayList;
/** Called when the activity is first created. */

super.onCreate(savedInstanceState);

You can use ListActivity Provided in Android.
You only have to manage your data to required format for this ListActivity.
You Can place action on button instead of Menu Option.
package your_package_name;
import android.app.ListActivity;
import android.app.NotificationManager;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;
public class your_activity_name extends ListActivity {
private static final int checkedItem= 0;
private String[] databaseContent;
String checkedItems = new String(); // comma separated
String uncheckedItems = new String(); // comma separated
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
databaseContent = your_data_from_database // this array should contain your data from database.
setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_multiple_choice, databaseContent));
getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
boolean result = super.onCreateOptionsMenu(menu);
menu.add(0, checkedItem, 0, R.string."String you want to show");
return result;
}
#Override
public boolean onMenuItemSelected(int featureId, MenuItem item)
{
switch(item.getItemId())
{
case checked:
{
int reqlength = getListAdapter().getCount();
for (int i = 0; i < reqlength ; i++)
{
if (getListView().isItemChecked(i)) {
checkedItems = checkedItems.concat(databaseContent[i]).concat(",");
}
else {
uncheckedItems = uncheckedItems.concat(databaseContent[i]).concat(",");
}
}
Thread thread = new Thread(){
#Override
public void run() {
if ( checkedItems.length() > 0 ||
uncheckedItems.length() > 0
)
{
//Here is your desired output in checkedItems & uncheckedItems
}
}
};
thread.start();
Toast.makeText(your_activity_name.this, R.string.your_string, Toast.LENGTH_SHORT).show();
finish();
return true;
}
}
return super.onMenuItemSelected(featureId, item);
}
#Override
protected void onPause()
{
super.onPause();
}
#Override
protected void onResume()
{
super.onResume();
}
}

Cant run another activity from a FragmentActivity.!

I have an activity with a ViewPager containing 3 fragments.
Each fragment is to hold a listview, and I wish to start a new activity when a list item is clicked.
I am unable to run the startActivity() method from the onItemClickListener. Help!

EDIT :
When i try to call startActivity(), I get this error in onItemClickListener.
Cannot make a static reference to the non-static method startActivity(Intent) from the type Activity.

Just Change the code for each fragment
public static class PairedDevicesFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.paired_devices, container, false);
// Find and set up the ListView for paired devices
pairedListView = (ListView) rootView.findViewById(R.id.paired_devices);
pairedListView.setOnItemClickListener(mDeviceClickListener);
new Handler().post(new Runnable() {
#Override
public void run() {
devicesAdapter = new DevicesCursor(getActivity().getApplicationContext(), dbHelper.DTgetAllData());
pairedListView.setAdapter(devicesAdapter);
}
});
pairedListView .setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
Cursor c = dbHelper.DTgetAllData();
c.moveToPosition(arg2);
String device = c.getString(0);
// Create the result Intent and include the MAC address
Intent intent = new Intent(getActivity(),ChatActivity.class);
intent.putExtra(DEVICE_DET, device);
// Set result and finish this Activity
getActivity().startActivity(intent);
}
});
return rootView;
}
}

Give this a try,
Instead of doing it this way, getActivity().startActivity(intent);
try this,
BTListDevice.this.startActivity(intent);

Change the onItemClick Code as following
static OnItemClickListener mDeviceClickListener = new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> av, View v, int arg2, long arg3) {
// Cancel discovery because it's costly and we're about to connect
mBtAdapter.cancelDiscovery();
Cursor c = dbHelper.DTgetAllData();
c.moveToPosition(arg2);
String device = c.getString(0);
// Create the result Intent and include the MAC address
Intent intent = new Intent(getActivity(),ChatActivity.class);
intent.putExtra(DEVICE_DET, device);
// Set result and finish this Activity
getActivity().startActivity(intent);
}
};

Try this fragment of code
// Create the result Intent and include the MAC address
Intent intent = new Intent(getActivity(), ChatActivity.class);
intent.putExtra(DEVICE_DET, device);
// Set result and finish this Activity
startActivity(intent);

You have to think about what you want your Fragment to be - Fragment or SherlockFragment?
You import this:
import com.actionbarsherlock.view.Menu;
import com.actionbarsherlock.view.MenuInflater;
import com.actionbarsherlock.view.MenuItem;
And so, your overrides aren't overrides because Menu & friends are different classes right now than what Fragment needs - they are ActionBarSherlock's classes.
If you extend SherlockFragment instead, your overrides should work, and it is recommended to extend SherlockFragment if you are using ActionBarSherlock (which based on your tags, you are).
If you want to keep this as a regular fragment, then import:
android.view.Menu
android.view.MenuItem
android.view.MenuInflater

then selecting the profile menu option takes me to Profile, which crashes trying to get extras.
I have checked data using toast and it's there. any ideas?

Your problem is most likely that you add a String extra (as cursor.getString(cursor.getColumnIndexOrThrow(OverLimitDbAdapter.KEY_ROWID)) returns a String) - but try to get a Long extra - which does not compute.
The following should fix the problem:
mRowId = extras != null ? Long.parseLong( extras.getString(OverLimitDbAdapter.KEY_ROWID) ) : null;

In your Overthelimit class you set the value with the following line:
myIntent1.putExtra(OverLimitDbAdapter.KEY_ROWID, cursor.getString(cursor.getColumnIndexOrThrow(OverLimitDbAdapter.KEY_ROWID)));
This puts a String value into the intent extras. Trying to get the same value as a Long value will make you applications crash, as it does not exist as a Long value. If you instead convert the value you get from your cursor object (or gets it directly as a Long from your cursor), your application should not crash anymore. Alternatively, you can get your value from the intent extras by using getString(), not getLong().

I think it giving type casting error as you store the value as string in put try to type cast at putting the value time or get the as string and then convert to long value but for type casting may be you getting type casting error in this so put into the try catch block and see the logcat details to detecting the error
type cast here from string to long or
myIntent1.putExtra(OverLimitDbAdapter.KEY_ROWID,cursor.getString(cursor.getColumnIndexOrThrow(OverLimitDbAdapter.KEY_ROWID)));
or get as string here and then type cast from string to long
String s = extras.getString(OverLimitDbAdapter.KEY_ROWID);
mRowId = extras != null ? Long.parseLong(s): null;

Android: Database help -Return all items in a specific column

i am really stuck. I am familiar in Java and Android development but i do not have any experience with databases. This is my first time. I have been going through multiple tutorials but i cannot figure out how return all the values from a specific row and set it to a single string.
Below is my database console. I was able to get all the items and display it in my view but i intended on writing a specific function to do something with all the data in only the TITLE column. Can anyone shed any light or provide a small routine to get all the items from the TITLE column into a single string? The very last function is my getTitleList that is where i would like to gather the data
Here is the function:
public void getTitleList(){
cursor = db.rawQuery("SELECT TITLE FROM table", null);
cursor.close();
}
Here is my class

}
public void getTitleList(){

}
}

unless i missunderstood the Question to get all items from your query in a cursor, loop through all items and concatenate into a string you would do something like this:
// constants of column indexes
int INDEX_ROWID = 0;
int INDEX_TITLE = 1;
...
db = new MyDBAdapter(this);
db.open();
Cursor c = db.getTitleList();
startManagingCursor(c);
String allTitles;
// loop through cursor
while(c.moveToNext()) {
allTitles += c.getString(INDEX_TITLE);
}
Hope that helps
