Question

我不想在我的机器人中构建短信触发的应用程序。我知道市场上有很多应用程序要做，但我只是想自己尝试。

我的短信接收器项目和我的来电项目一样正常。我想将它们合并为一个应用程序，但我不在乎。有人可以帮我一把吗？

这是我从某个地方获得并经过测试工作的代码片段。

Caller.java

package pi.redphone;

import android.app.Activity;
import android.content.ActivityNotFoundException;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;



public class Caller extends Activity 
{
    private Context context;

    /** Called when the activity is first created. */
    @Override
       public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        String num = "2217238";
        call(num);
    } 

 public void call(String number) 
{
    try 
    {
        Intent callIntent = new Intent(Intent.ACTION_CALL);
        callIntent.setData(Uri.parse("tel:"+number));
        startActivity(callIntent);
    } 
    catch (ActivityNotFoundException activityException) 
    {
        Log.e("dialing-example", "Call failed", activityException);
    }
}

}

上面代码中的电话号码是硬编码的，安装后会拨打此号码 2217238

SmsReceiver.java

package pi.redphone;

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 SmsReceiver extends BroadcastReceiver
{


    public void onReceive(Context context, Intent intent) 
    {
        Bundle bundle = intent.getExtras();
        //SmsMessage msg = null;
        String sender = null;
        String msgBody = null;

        if(bundle != null)
        {
            Object[] sms = (Object[]) bundle.get("pdus");

            for(int i=0; i<sms.length; i++)
            {
                SmsMessage msg = SmsMessage.createFromPdu((byte[]) sms[i]);
                sender = msg.getOriginatingAddress(); //store sender's mobile #
                msgBody = msg.getMessageBody(); //msg content

            }
            Toast.makeText(context, sender, Toast.LENGTH_LONG ).show();


        }

    }

}

安装后，应用程序将发出此错误

应用程序Callforwarding意外停止工作。 PLS 再试一次..

其实我想要做的是当有人向我的Android发送短信时我的SmsReceiver将提取发件人的手机号码，然后它会回拨..发件人的号码存储在发件人变量中。

我想做这样的事情

call(sender);

但这并不容易..我可以将源代码组合在一起但没有错误，但我无法在安装后使其工作......

这将是我的第一个Android应用程序，如果我可以让它工作..;）

    }

}

我感觉代码是正确的，但我无法弄清楚如何解决问题..

我不知道如何遵循你的建议，因为我总是收到错误。但请帮我检查一下我做得对..

这是我的最新代码。呼叫正在运行，但我的短信接收器没有。

我不知道如何打电话给我

Answer 1

您必须发布logcat错误以获取有关崩溃的帮助。但拨打电话并不难。我最初的猜测是你在Android清单中缺少权限。它是否拥有SMS和Dialer应用程序的所有权限？

确保发件人仅存储电话号码。我相信它是。但

您确实不需要包含第一个应用程序。您需要的唯一代码是

try  
{  
    Intent callIntent = new Intent(Intent.ACTION_CALL);  
    callIntent.setData(Uri.parse("tel:"+number));  
    startActivity(callIntent);  
}   
catch (ActivityNotFoundException activityException)   
{  
    Log.e("dialing-example", "Call failed", activityException);  
}

将号码替换为发件人，您应该全部设置。

如果您想保留这两项活动，可以执行以下操作。     Intent callIntent = new Intent（this，Caller.class）;
    callIntent.putExtra（“phoneNumber”，发件人）;
    startActivity（callIntent）;

在通话活动中，你会

Bundle extras = getIntent().getExtras();  
string sender = extras.getInt("phoneNumber");

然后，您可以提示用户并询问您是否希望该应用拨打该号码。或者你可以马上打电话。如果您只是在没有确认的情况下立即拨打＃，请在我的帖子中使用上面提到的第一个解决方案。
