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 message
			int 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;
			else
				return 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
