前两篇博客并分别讲了获取联系人和通话记录的知识，这篇主要介绍短信获取知识，短信在通讯管理中应该说是一个难点，因为短信涉及到短息会话和短信详情两个部分，并且短信的数据量比较大，可以采用AsyncQueryHandler框架来查询，同时采用CursorAdapter来绑定数据
其中短信中可以来获取联系人的头像和姓名。这个在代码工具类中有实现，如果联系人存在，则显示姓名，否则显示号码，如果联系人头像存在则显示头像，否则显示默认头像，如图片所示。这两部分功能在联系人和通话记录中均可以实现，有兴趣的童鞋可以修改。
查询框架
package cn.zxw.contact.utils;
import android.content.AsyncQueryHandler;
import android.content.ContentResolver;
import android.database.Cursor;
import android.support.v4.widget.CursorAdapter;
import android.util.Log;
/**
* QueryHandler框架
* @author zhan
*
*/
public class QueryHandler extends AsyncQueryHandler {
private static final String TAG = "QueryHandler";
public QueryHandler(ContentResolver cr) {
super(cr);
}
@Override
protected void onQueryComplete(int token, Object cookie, Cursor cursor) {
super.onQueryComplete(token, cookie, cursor);
String names[] = cursor.getColumnNames();
for (String name : names) {
Log.i(TAG, name);
}
// 查询完成
//
if (cookie != null && cookie instanceof CursorAdapter) {
// 把查询出来的cursor结果设置给adapter
CursorAdapter adapter = (CursorAdapter) cookie;
adapter.changeCursor(cursor);
}
}
}
