Android读取彩信附件
本帖最后由 hiand 于 2011-9-7 13:07 编辑 代码主要实现一个读取彩信列表的功能，原本功能是点击某条彩信记录，显示相关包括文本、图片（该处并没有对音频附件处理）等，该处就把他们整合到一起了。 public class SmsPage extends ListActivity{private final String TAG="SmsPage";
private final Uri CONTENT_URI = Uri.parse("content://mms/inbox"); //查询彩信收件箱
private final Uri CONTENT_URI_PART = Uri.parse("content://mms/part"); //彩信附件表
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.smslist);
Cursor cursor = getContentResolver().query(CONTENT_URI, null, null,null, null);
if(cursor.getCount()>0){
MyAdapter adapter = new MyAdapter(this,R.layout.smsitem,cursor,new String[]{},new int[]{});
setListAdapter(adapter);
}
}
public class MyAdapter extends SimpleCursorAdapter{

public MyAdapter(Context context, int layout, Cursor c, String[] from,
int[] to) {
super(context, layout, c, from, to);
