Queue and Display Call Log in a Simple List, Names Only

Postby iPaul Pro » Tue Mar 17, 2009 6:50 pm

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:

  6.     <application android:icon="@drawable/icon" android:label="@string/
  7. app_name" android:debuggable="true">
  8.         <activity android:name=".Calls"
  9.                  android:label="@string/app_name">
  10.             <intent-filter>
  11.                 <action android:name="android.intent.action.MAIN" />

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).

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

Using xml Syntax Highlighting
  1. <uses-permission android:name="android.permission.READ_CONTACTS"></uses-permission>
Parsed in 0.000 seconds, using GeSHi 1.0.8.4

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.

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