Android通讯录管理三之短息获取和发送短息

浏览数：37 / 时间：2015年06月11日

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

public class MsgActivity extends Activity implements OnItemClickListener {

	private ListView lv;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);

	}

	/**

	 */
	private void startQuery() {
		QueryHandler mQueryHandler = new QueryHandler(getContentResolver());
		// 执行查询

		 */
		Uri uri = Uri.parse("content://sms/conversations");

		// null,"date desc");
		mQueryHandler.startQuery(0, adapter, uri, projection, null, null,

	}

	// 自定义CursorAdapter

			TextView tv_body = (TextView) view.findViewById(R.id.tv_body);
			TextView tv_date = (TextView) view.findViewById(R.id.tv_date);
			// 由于Listview的数据显示是通过适配器来控制的，所以到bindView方法中来控制checkbox 的显示
			// 获取数据
			int id = cursor.getInt(THREAD_ID_COLUMN_INDEX);
			String address = cursor.getString(ADDRESS_COLUMN_INDEX);
			int msg_count = cursor.getInt(MSG_COUNT_COLUMN_INDEX);
			long date = cursor.getLong(DATE_COLUMN_INDEX);

			System.out.println(address);
			// 绑定数据
			String displayName = ContactsUtils.getContactNameByAddress(
					getApplicationContext(), address);
			if (TextUtils.isEmpty(displayName)) {

			} else {

				Bitmap bitmap = ContactsUtils.getContactPhotoByAddress(
						getApplicationContext(), address);
				if (bitmap == null) {

				} else {
					iv_header.setImageBitmap(bitmap);
				}
			}
			tv_body.setText(body);
			String dataStr = TimeUtils
					.formatDate(getApplicationContext(), date);
			tv_date.setText(dataStr);
		}

	}

	@Override
	public void onItemClick(AdapterView<?> parent, View view, int position,
			long id) {
		//传递数据
		Cursor cursor = (Cursor) adapter.getItem(position);
		int _id = cursor.getInt(THREAD_ID_COLUMN_INDEX);

短信发送方法：

	/**
	 * 发送短信
	 * @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<String> parts=smsManager.divideMessage(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);
	}
