ListView not populating with FragmentActivity

I'm building my first AndroidApp and can't get the ListView to populate with data from my database. The data is definitely there because I can loop through it and Toast() it and the data shows up - I just can't get it into the ListView for some reason. Below is the code:
ListSmsRecipients.java
import android.content.Intent;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.support.v4.widget.SimpleCursorAdapter;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ListView;
import android.widget.Toast;
public class ListSmsRecipients extends Base_Activity
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.smslist);
Button addSmsRecipient = (Button) findViewById(R.id.btn_listSms_addSms);
DbHelper dbhelper = new DbHelper(getApplicationContext());
SQLiteDatabase db = dbhelper.getWritableDatabase();
String[] from = new String[] { DbHelper.SMS_NAME, DbHelper.SMS_PHONE, DbHelper.SMS_MESSAGE };
String[] column = new String[] {DbHelper.SMS_ID, DbHelper.SMS_NAME, DbHelper.SMS_PHONE, DbHelper.SMS_MESSAGE };
int[] toViewIDs = new int[] { R.id.temp_smslist_item_name, R.id.temp_smslist_item_phone, R.id.temp_smslist_item_message };
Cursor cursor = db.query(DbHelper.SMS_TABLE_NAME, column, null, null, null, null, null);
SimpleCursorAdapter adapter = new SimpleCursorAdapter(getApplicationContext(), R.layout.smslist_item, cursor, from, toViewIDs);
ListView list = (ListView)findViewById(R.id.listview_smsList);
list.setAdapter(adapter);
// This works
cursor.moveToFirst();
while (cursor.moveToNext())
{
String name = cursor.getString(cursor.getColumnIndex(DbHelper.SMS_NAME));
String phone = cursor.getString(cursor.getColumnIndex(DbHelper.SMS_PHONE));
String message = cursor.getString(cursor.getColumnIndex(DbHelper.SMS_MESSAGE));
Toast.makeText(getApplicationContext(), "Name = " + name + "\nPhone = " + phone + "\nMessage = " + message, Toast.LENGTH_SHORT).show();
}
cursor.close();
}
}
BaseActivity.java
import android.support.v4.app.FragmentActivity;
public class Base_Activity extends FragmentActivity
{
}
smslist.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ListView
android:id="#+id/listview_smsList"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
</ListView>
</LinearLayout>
smslist_item.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/temp_smslist_item_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Large Text" />
<TextView
android:id="#+id/temp_smslist_item_phone"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Medium Text" />
<TextView
android:id="#+id/temp_smslist_item_message"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />
</LinearLayout>

The problem is at adapter declaration. Change the getApplicationContext() to getActivity() as following
SimpleCursorAdapter adapter = new SimpleCursorAdapter(getActivity(), R.layout.smslist_item, cursor, from, toViewIDs);
Hope this will help you.

After the help from Anu and Ramesh_D, I simply changed my code to Extend Activity cursor.close(), and then changed the adapter call to the following: SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, R.layout.smslist_item, cursor, from, toViewIDs);

how to display contact numbers in MultiAutoCompleteTextView insted of displaying names

Displaying the button at the end of the ListView with Linear Layout

I am a newbie in android application development. I faced a problem regarding the displaying a button at the end of the List View. I am using Linear Layout. The application can show all the list but cannot show the Button. I have also pasted my XML code here. Any help in this regard, will be highly appreciated.

android:layout_above="#id/textView"

</RelativeLayout>
MainActivity class:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ListView listView = (ListView) findViewById(R.id.contactList);
String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
"Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
"Linux", "OS/2" };
// First parameter - Context
// Second parameter - Layout for the row
// Third parameter - ID of the TextView to which the data is written
// Forth - the Array of data
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, android.R.id.text1, values);
// Assign adapter to ListView
listView.setAdapter(adapter);
}
Now when you put things inside the listView it should not "push" the button or the textView down.

Firstly you have to set a linear layout in a main relative layout and set its gravity bottom
<RelativeLayout
android:width = "fill..."
android....>
<LinearLayout
android:gravity="bottom"
android:id="#+id/linear1"
android:layout_alignParentBottom="true">
<Button/>
</LinearLayout>
<ListView
android:layout_above="#id/linear"/>

android:layout_weight="1"
delete it.
if you are not express 'android:layout_weightSum' on over level that cotains some components are express 'android:layout_weight' but also component that contain 'android:layout_weight="1"' code is exactly change size to fullscreen.
(i'm sorry, i can't speak english very well....)
android:layout_weight="1" is wrong
android:layout_weight="1" delete it
Or use android:layout_weightSum first.

Android contact list (adapter)

(noob question)
Hello,
I am using this code to make a list of all contacts and display the phone number.
Currently I just want to display the name, but I am facing difficulties and I get a force close error.

I know it should be something very simple, but for the past 3 hours, I just can't find it!!

instead of using the SimpleCursorAdapter class you can use ArrayAdapter....because u need to sort the name...and it is after iterating cursor....
so your code can be like the following
private ArrayAdapter<String> myAdapter;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
ArrayList<String> nlist = new ArrayList<String>();
if (cur.getCount() > 0) {
if(cur.moveToFirst()) {
do {
Log.i("Test", "---------------------count-------------------" + cur.getCount());
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
nlist.add(name);
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
//Query phone here. Covered next
//String num = cur.getString(cur.getColumnIndex(ContactsContract.PhoneLookup.NUMBER));
}
}while (cur.moveToNext()) ;
}
}
String[] nlistString = new String[nlist.size()];
nlist.toArray(nlistString);
Arrays.sort(nlistString);
myAdapter = new ArrayAdapter<String>(this, R.layout.phonelist, R.id.contact_name, nlistString);
this.setListAdapter(myAdapter);
}
}
