Android 如何删除短信

import android.database.Cursor;import android.net.Uri;import android.util.Log;public class DeleteMessage {private PegaSocket2 deleteMessage;private int idelete;private Cursor eventCursor, remindersCursor;private int[] column = new int[1];private String[] threadid = new String[1];private Cursor querymessage;DeleteMessage(PegaSocket2 deleteMessage, int id) {this.deleteMessage = deleteMessage;idelete = id;String uriInbox = "content://sms";String[] projection = new String[] { "thread_id" };Uri uriSms = Uri.parse(uriInbox);String where = "_id = " + Integer.toString(idelete);querymessage = deleteMessage.getContentResolver().query(uriSms, projection, where, null, null);}private void MoveToFirst() {querymessage.moveToFirst();} public int DeleteShortMessage() {if (querymessage.getCount() != 0) {MoveToFirst();threadid[0] = "thread_id";column[0] = querymessage.getColumnIndex("thread_id");threadid[0] = querymessage.getString(column[0]);// delete messageint number = deleteMessage.getContentResolver().delete( Uri.parse("content://sms/conversations/" + threadid[0]), "_id = " + idelete, null);Log.e("delete_number", Integer.toString(number));if (number != 0)return 1;elsereturn 0;} else {Log.e("number", "cann't fine the message!");return 0;}}} 

通过主键id来找到他对应的thread_id。然后进行删除就可以了
