私のプログラムは、SMS メッセージを正常に送受信できます。プログラムで特定の電話番号からのみ SMS を受信したいのですが、他のすべての番号からのメッセージは電話の受信トレイに送られます。私が使用するコードは以下のとおりです。それは機能せず、すべての SMS メッセージが電話の受信トレイに送られます。メソッドmsg_fromでは、ループでSmsReceiver値を取得できず、常に.fornull

private TextView showSms;

// _smsReceiver.onReceive(getBaseContext(), getIntent());

Intent _intent = getIntent();
ReceivedSms = _intent.getStringExtra("message");
showSms = (TextView) this.findViewById(R.id.txt_Show);
showSms.setText(ReceivedSms);

public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
