如何在Android中的SMS收件箱中删除所有消息

Question

我想只需单击一下按钮即可删除消息中的所有消息。但是我已经尝试了下面的编码，它行不通...有人可以帮助我实现这一目标吗？谢谢...

public class DeleteSMSActivity extends Activity implements OnClickListener{
/** Called when the activity is first created. */
Button press;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    press = (Button)findViewById(R.id.button1);
    press.setOnClickListener(this);
}
public void onClick(View view){
    ContentResolver cr = getContentResolver();
    Uri inboxUri = Uri.parse("content://sms/inbox");
    Cursor c = cr.query(inboxUri , null, null, null, null);
    while (c.moveToNext()) {
        // Delete the SMS
        String pid = c.getString(0); // Get id;
        String uri = "content://sms/" + pid;
        cr.delete(Uri.parse(uri), null, null);
    }
}
}

我应该添加什么清单？使用我的Galaxy Tab 2

Answer 1

尝试使用_id删除：

Cursor c = getApplicationContext().getContentResolver().query(Uri.parse("content://sms/"), null, null, null,null);
try {
      while (c.moveToNext()) {
         int id = c.getInt(0);
         getApplicationContext().getContentResolver().delete(Uri.parse("content://sms/" + id), null, null);
      }
    }catch(Exception e){
         Log.e(this.toString(),"Error deleting sms",e);
    }finally {
      c.close();
    }

Answer 2

delete uri是" content：//sms/" id;

Uri inboxUri = Uri.parse("content://sms/inbox");
int count = 0;
Cursor c = context.getContentResolver().query(inboxUri , null, null, null, null);
while (c.moveToNext()) {
    try {
        // Delete the SMS
        String pid = c.getString(0); // Get id;
        String uri = "content://sms/" + pid;
        count = context.getContentResolver().delete(Uri.parse(uri),
                null, null);
    } catch (Exception e) {
    }
}
return count;

用于从收件箱中删除SMS的

您需要使用清单中声明的权限

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

现在，您将能够删除收件箱SMS，现在您将无法关闭模拟器

今天，我找到了删除所有无循环的所有消息的方式，只是查询。

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