但没有发生，没有任何力量关闭和放大器;它没有被删除，任何帮助？

推荐答案

您需要做的两个步骤。是这样的：

You'll need to do it in two steps. something like this:

A 按地址Queary SMS数据库，以获得您的SMS的消息ID：

A. Queary SMS database by address to obtain your SMS's message id:

 String numberFilter = "address='"+ phoneNumber + "'";
 String messageid = null;
 Cursor cursor = mContext.getContentResolver().query(Uri.parse("content://sms/"), 
              null, numberFilter, null, null);
 if (cursor.moveToFirst()) {
      messageid = cursor.getString(0);
 }

乙使用消息id删除短信：

B. Delete SMS using message id:

getContentResolver().delete(Uri.parse("content://sms/" + messageid), null, null);

结果

现在，多个缺失。你报多删除失败，当你
使用光标迭代（而cursor.moveToFirst（））。我从来没有尝试过，但我认为
它是与光标之后删除无效。
尝试，而不是之前的每个删除，重新启动光标，像这样：

Now, for multiple deletions. You reported multi-deletion failed when you use cursor iteration (while cursor.moveToFirst()). I never tried it but I assume It has something to do with cursor invalidated after delete. Try instead to restart the cursor before each delete, something like this:

 for (;;) {
     // restart cursor before each delete
     String messageid = null;
     Cursor cursor = mContext.getContentResolver().query(Uri.parse("content://sms/"), 
                  null, numberFilter, null, null);
     if (!cursor.moveToFirst()) {
       break; // nothing more to delete
     }
     // delete single record
     messageid = cursor.getString(0);
     getContentResolver().delete(Uri.parse("content://sms/" + messageid), null, null);
 }

您将需要写短信权限：

<uses-permission android:name="android.permission.WRITE_SMS"/>
