Android通讯录管理三之短息获取和发送短息

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);
		}
	}
}
短信会话获取

}
短信详情页面,可以实现发送短息

短信发送方法:

 

 

	/**

	 * @param address
	 * @param content
	 */
	public static void sendMsg(Context context,String address,String content){
		SmsManager smsManager=SmsManager.getDefault();//如果短信太长,拆分短信
		ArrayList parts=smsManager.pideMessage(content);
		smsManager.sendMultipartTextMessage(address, null, parts, null, null);
		//手动存储短信
		ContentResolver resolver=context.getContentResolver();
		Uri uri=Constants.SMS_URI;
		ContentValues values=new ContentValues();
		values.put(address, address);
		values.put(body, content);
		values.put(type, Constants.SEND_TYPE);
		values.put(date, System.currentTimeMillis());
		
		resolver.insert(uri, values);
	}
