如何在 textview 而不是 toast 中显示收到的短信

Question

我目前正在开发一个简单的 android 应用程序来读取 SMS 并在 TexView 而不是 Toast 中打印它。但是在接收器 activity 中，我们没有初始化 "findbyid" 因此我们无法在 textView 中打印短信。现在我在 Toast 中显示 SMS 以进行测试，但我不想在 Toast 中显示它。我也阅读了 questions/answer 和其他文章，但找不到我想要的。

接收者activity,

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activity是空的，因为我找不到放在这里的代码。

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 TextView 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_smsclass收到短信时添加以下代码

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

Answer 2

每当您在接收器中收到短信时，请在您的 activity 中注册您的接收器
在您的接收器中使用此代码 class

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

在此之后在您的 activity 中注册广播接收器

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);
}
