I am trying to construct a simple app that allows me to see my call log, displaying names only, in a "simple_list_item_1". I am totally new to Java and Android and this is really the first step in creating my first app.

Here's what I've got (go easy, please):

Manifest:

XML:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.ipaulpro.calls"
      android:versionCode="1"
      android:versionName="1.0.0">
    <application android:icon="@drawable/icon" android:label="@string/
app_name" android:debuggable="true">
        <activity android:name=".Calls"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category
android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
    <uses-permission android:name="android.permission.READ_CONTACTS"></
uses-permission>
</manifest>


Calls.java

Java:
package com.ipaulpro.calls;

import android.app.ListActivity;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.CallLog;
import android.widget.ListAdapter;
import android.widget.SimpleCursorAdapter;

public class Calls extends ListActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.main);

        Cursor c = getContentResolver().query(
                       android.provider.CallLog.Calls.CONTENT_URI,
                       null, null, null,
                       android.provider.CallLog.Calls.DATE+ " DESC");
           startManagingCursor(c);

           ListAdapter adapter = new SimpleCursorAdapter(
               this,
               android.R.layout.simple_list_item_1,
               c,
               new String[] {CallLog.Calls.CACHED_NAME},
               new int[] {CallLog.Calls.MISSED_TYPE}
       );

       setListAdapter(adapter);
    }

}


Main.xml

XML:
<?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
         android:orientation="vertical"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent">

     <ListView android:id="@id/android:list"
               android:layout_width="fill_parent"
               android:layout_height="fill_parent"

     />
           <TextView  id="@+id/row_number"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
          />

</LinearLayout>


So the app starts, but displays an empty list (with borders).

Any helps, tips, links would be very appreciated.

Thanks in advance.

Okay, so I've achieved my intended goal (the first step in my application).

I thought I'd share the code to output a simple list with cached names from the call log (no name displayed for UNKNOWN and PRIVATE numbers -- I'm working on that and will report when I figure it out - again, I'm a newb and know this can be achieved with an "if - then" statement - just don't know how to do it yet).

Java:
import android.app.ListActivity;
import android.database.Cursor;
import android.os.Bundle;
import android.widget.SimpleCursorAdapter;

public class Calls extends ListActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
              
        Cursor c = getContentResolver().query(
                    android.provider.CallLog.Calls.CONTENT_URI,
                    null,
                    null,
                    null,
                    android.provider.CallLog.Calls.DATE+ " DESC");
        startManagingCursor(c);

           // Now create an adapter and set it to display using android.R.layout.simple_list_item_1
           SimpleCursorAdapter calls = new SimpleCursorAdapter(
                  this,
                   android.R.layout.simple_list_item_1,
                   c,
                   new String[] { android.provider.CallLog.Calls.CACHED_NAME },
                   new int[] { android.R.id.text1 });
           setListAdapter(calls);
         
    }
}


There's no need to specify xml in your res/layout/ as we are using default Android styles.

The only change to the Manifest is adding the permission to read contact data (call log pulls from contacts)

Put
XML:
<uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission>

anywhere before or after the <application> tags.

And in case someone is wondering, here how you would output the cached name and number on a two-line list, using the "simple list 2" template.

Java:
import android.app.ListActivity;
import android.database.Cursor;
import android.os.Bundle;
import android.widget.SimpleCursorAdapter;

public class Calls extends ListActivity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
              
        Cursor c = getContentResolver().query(
                    android.provider.CallLog.Calls.CONTENT_URI,
                    null,
                    null,
                    null,
                    android.provider.CallLog.Calls.DATE+ " DESC");
        startManagingCursor(c);

           // Now create an adapter and set it to display using android.R.layout.simple_list_item_2
           SimpleCursorAdapter calls = new SimpleCursorAdapter(
                  this,
                   android.R.layout.simple_list_item_2,
                   c,
                   new String[] { android.provider.CallLog.Calls.CACHED_NAME, android.provider.CallLog.Calls.NUMBER },
                   new int[] { android.R.id.text1, android.R.id.text2 });
           setListAdapter(calls);
                   
    }
}


Hope that helps someone out there. I'll keep this thread updated with my related findings.
