如何显示在TextView而不是Toast中收到的SMS

Question

我当前正在处理简单的Android应用程序，以阅读SMS并在TexView而不是Toast中打印。但是在接收器活动中，我们不会初始化" FindbyId"，因此我们无法在TextView中打印SMS。现在，我在Toast中显示SMS进行测试，但我不希望它在烤面包中。我还阅读了问题/答案以及其他文章，但找不到我想要的东西。

接收器活动，

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
import android.util.Log;
import android.widget.Toast;
public class read_sms extends BroadcastReceiver {
// Get the object of SmsManager

@Override
public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    final Bundle bundle = intent.getExtras();
    try {
        if (bundle != null) {
            final Object[] pdusObj = (Object[]) bundle.get("pdus");
            for (int i = 0; i < pdusObj.length; i++) {
                SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                String phoneNumber = currentMessage.getDisplayOriginatingAddress();
                String senderNum = phoneNumber;
                String message = currentMessage.getDisplayMessageBody();
                Log.i("SmsReciver", "senderNum: " + senderNum + ", message: " + message);
                //ourSMS.getSmsDetails(senderNum, message);
                // Show SMS notification
                //Toast.makeText(context, "senderNum: "+ senderNum + ", message: " + message, Toast.LENGTH_LONG).show();

                if(message.equals("Milind")){
                    Toast.makeText(context, "sms matched", Toast.LENGTH_LONG).show();
                }else {
                    Toast.makeText(context, "not matched", Toast.LENGTH_LONG).show();
                }
            } // end of for loop
        } // bundle
    } catch (Exception e) {
        // TODO: handle exception
        Log.e("SmsReciver", "Exception smsReciver" + e);
    }
}
}

我的家庭活动是空的，因为我找不到放置在这里的代码。

public class home extends AppCompatActivity {
TextView SMS_textview;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.home);
    SMS_textview = (TextView) findViewById(R.id.sms_text);

}
}

Answer 1

将该文本视图更改为

public static TextView SMS_textview;

添加方法

public void recivedSms(String message)
{
    try
    {
     SMS_textview.setText(message);
    }
    catch (Exception e)
    {
    }
}

在Read_sms类中，您回收SMS

时添加以下代码

  home Sms = new home();
  Sms.recivedSms(message );

Answer 2

每当收到接收者的文本
时，请在活动中注册您的接收者在接收器类中使用此代码

 Intent broadcastIntent = new Intent();
                broadcastIntent.putExtra("your key", your Value);
                broadcastIntent.setAction("link from  you have recieve a text");
                context.sendBroadcast(broadcastIntent);

在此注册后，您的活动中的广播接收器

private void registerSmsReciever() {
    IntentFilter intentFilter = new IntentFilter();
    intentFilter.addAction("link from  you have recieve a text");
  BroadcastReceiver  broadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            Log.d("onReceive", "Sms recieved in progress");
          String  message= intent.getStringExtra("key");
            textView.setText(intent.getStringExtra("key"));

        }
    };
    registerReceiver(broadcastReceiver, intentFilter);
}
