可以参考http://developer.android.com/guide/tutorials/views/hello-gridview.html
然后只需要修改：
public class MyAdapter extends BaseAdapter {
     private Context context;
     private String[] texts = {"aaa", "bbb", "ccc", "ddd", "eee", "fff", "eee", "hhh", "iii"};
     public MyAdapter(Context context) {   
      this.context = context;
     }
     public int getCount() {    return 9;}
     public Object getItem(int position) {    return null;}
     public long getItemId(int position) {    return 0;}
     public View getView(int position, View convertView, ViewGroup parent) {
         TextView tv;   
         if (convertView == null) {
                 tv = new TextView(context);       
                 tv.setLayoutParams(new GridView.LayoutParams(85, 85));
                     }
           else {
                  tv = (TextView) convertView;  
                   }
             tv.setText(texts[position]);   
             return tv;
       }

view集成的方法
public View getView(int position, View contentView, ViewGroup arg2)
    {        ViewHolder holder;       
           if (contentView == null) {
                       holder = new ViewHolder();           
                       contentView = inflater.inflate(R.layout.my_magic_list,null);          
                        holder.label = (TextView) contentView.findViewById(R.id.label);           
                        contentView.setTag(holder);        }
            else {            holder = (ViewHolder) contentView.getTag();        }       
            holder.label.setText(getLabel());       
            return contentView;    }

•Use convertView
•If you have images, don't scale your images on the fly. Use Bitmap.createScaledBitmap to create a scaled bitmap and put that into your views
•Use a ViewHolder so you don't have to call a bunch of findViewByIds() every time
•Decrease the complexity of the views in your listview. The fewer subviews, the better. RelativeLayout is much better at this than, say, LinearLayout. And make sure to use if you're implementing custom views.

4.LayoutInflater li = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);   
final View dialogView = li.inflate(R.layout.edit_event, null);   
ArrayList<String> routes = new ArrayList<String>(); 
ArrayAdapter<String> aa = new ArrayAdapter<String>(GOFdroid.this, android.R.layout.simple_spinner_item, routes);
    aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);  
     Spinner destSpinner = (Spinner) dialogView.findViewById(R.id.edit_event_destination);
        String dest = events.get(pos).getDestination();
           int routesPos = routes.indexOf(dest);
              Log.d(TAG, "Dest: " + dest + ", pos: " + routesPos); 
              
                   destSpinner.setAdapter(aa);
destSpinner.setSelection(routesPos);
最后一句是在spiner没有显示之前显示一个特定信息

5.

  Cursor c = getContentResolver().query(People.CONTENT_URI, null, null, null, null); 
    startManagingCursor(c); 
 
    SpinnerAdapter adapter = new SimpleCursorAdapter(this, 
    // Use a template that displays a text view 
            android.R.layout.simple_gallery_item, 
            // Give the cursor to the list adatper 
            c, 
            // Map the NAME column in the people database to... 
            new String[] {People.NAME}, 
            // The "text1" view defined in the XML template 
            new int[] { android.R.id.text1 }); 
5.只想显示一个

display a static list of String objects

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_gallery_item, new String[] {People.NAME}); 
add more String objects to the list later

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_gallery_item, new ArrayList<String>()); 

其实无论呼入呼出 都可以使用receive捕获相关信息，当然 android不支持程序不能拨电话的 我们也是间接实现
public void onReceive(Context context, Intent intent){
    String action = intent.getAction();
        if (Intent.ACTION_NEW_OUTGOING_CALL.equals(action)) {
                String number = getResultData();
                        if (number.startsWith(BYPASS_PREFIX)) {
                                     setResultData(number.substring(BYPASS_PREFIX.length()));
                               }
                         else {             // do additional processing        }    }

2.拆解短信
http://www.androidcompetencycenter.com/2008/12/android-api-sms-handling/
public class SMSReceiver extends BroadcastReceiver{
    public void onReceive(Context context, Intent intent)    {
            Bundle myBundle = intent.getExtras();       
            SmsMessage [] messages = null;
            String strMessage = "";
                    if (myBundle != null)
                            {
                                        Object [] pdus = (Object[]) myBundle.get("pdus");
                                        messages = new SmsMessage[pdus.length];
                                        for (int i = 0; i < messages.length; i++)
                                                   {
                                                                  messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
                                                                  strMessage += "SMS From: " + messages[i].getOriginatingAddress();
                                                                  strMessage += " : ";               
                                                                  strMessage += messages[i].getMessageBody();
                                                                                  strMessage += "\n";          
                                                     }
               Toast.makeText(context, strMessage, Toast.LENGTH_SHORT).show();        }    }}

                                         if (bundle != null) {

                                                                 }            }        }    }

4.得到所有短信
Uri allMessage = Uri.parse("content://sms/");ContentResolver cr = getContentResolver();Cursor c = cr.query(allMessage, null, null, null, null);while  (c.moveToNext()) {   String row = c.getString(1);}
5.得到未读短信
for (int i = 0; i < messages.length; i++)            {                messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);                from = ""+messages[i].getOriginatingAddress();                body = ""+messages[i].getMessageBody();                inSIM = (messages[i].getIndexOnSim() != -1);                if (inSIM)                {                    int status = messages[i].getStatusOnSim();                    if (status == SmsManager.STATUS_ON_SIM_UNREAD)                    {                       Toast.makeText(context, "Message Unread on SIM: "+from+": "+body, Toast.LENGTH_SHORT).show();                    }                }                            } 

5.得到来电的电话号码：

<receiver android:name=".CustomBroadcastReceiver"> 
        <intent-filter> 
                <action android:name="android.intent.action.PHONE_STATE" />      
        </intent-filter>

        Log.v(TAG, "WE ARE INSIDE!!!!!!!!!!!"); 
        Log.v(TAG, incomingNumber); 
 
        switch(state){ 
                case TelephonyManager.CALL_STATE_RINGING:

    Bundle bundle = intent.getExtras();

        Log.v(TAG, "phoneNr: "+phoneNr); 
 
} 

4. 比较好的实例讲解http://mobiforge.com/developing/story/sms-messaging-android

- (IBAction)selectExistingPicture {
    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) 
        {
        UIImagePickerController *picker = [[UIImagePickerController alloc] init];
        picker.delegate = self;
        picker.allowsImageEditing = YES;
        picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        [self presentModalViewController:picker animated:YES];
        [picker release];
    }
    else {

        [alert show];
        [alert release];
    }
}

#pragma mark UIImagePickerControllerDelegate
- (void)imagePickerController:(UIImagePickerController *)picker 
        didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo 
{
        imageView.image = image;        //imageView为自己定义的UIImageView
