有没有可靠的方法可以通过代码屏蔽进出短信?如果实际的短信消息被接收到,那也没关系,但我希望屏蔽任何收到短信的通知。此外,用户不应该被允许发送(最好甚至不要输入)短信。这是否可能?
谢谢

您无法阻止发送的文本消息。
以下是我用于阻止接收短信的方法。
SmsReceiver.java
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.widget.Toast;
public class BroadCastReceiver extends BroadcastReceiver
{
/** Called when the activity is first created. */
private static final String ACTION = "android.provider.Telephony.SEND_SMS";
public static int MSG_TPE=0;
public void onReceive(Context context, Intent intent)
{
String MSG_TYPE=intent.getAction();
if(MSG_TYPE.equals("android.provider.Telephony.SMS_RECEIVED"))
{
// Toast toast = Toast.makeText(context,"SMS Received: "+MSG_TYPE , Toast.LENGTH_LONG);
// toast.show();
Bundle bundle = intent.getExtras();
Object messages[] = (Object[]) bundle.get("pdus");
SmsMessage smsMessage[] = new SmsMessage[messages.length];
for (int n = 0; n < messages.length; n++)
{
smsMessage[n] = SmsMessage.createFromPdu((byte[]) messages[n]);
}
// show first message
Toast toast = Toast.makeText(context,"BLOCKED Received SMS: " + smsMessage[0].getMessageBody(), Toast.LENGTH_LONG);
toast.show();
abortBroadcast();
for(int i=0;i<8;i++)
{
System.out.println("Blocking SMS **********************");
}
}
else if(MSG_TYPE.equals("android.provider.Telephony.SEND_SMS"))
{
Toast toast = Toast.makeText(context,"SMS SENT: "+MSG_TYPE , Toast.LENGTH_LONG);
toast.show();
abortBroadcast();
for(int i=0;i<8;i++)
{
System.out.println("Blocking SMS **********************");
}
}
else
{
Toast toast = Toast.makeText(context,"SIN ELSE: "+MSG_TYPE , Toast.LENGTH_LONG);
toast.show();
abortBroadcast();
for(int i=0;i<8;i++)
{
System.out.println("Blocking SMS **********************");
}
}
}
}

关于阻止短信的到来。您可以注册具有高优先级的广播接收器,以便在系统应用程序被调用之前调用您的代码。然后在广播接收器中,您可以中止广播,其他应用程序将看不到它。
在清单中注册接收器:
<receiver android:name=".SmsReceiver">
<intent-filter android:priority="2147483647">
<action android:name="android.provider.Telephony.SMS_RECEIVED" />
</intent-filter>
</receiver>
然后在广播接收器中:
@Override
public void onReceive(Context context, Intent intent) {
abortBroadcast();
}
