如何结合我的两个项目 1.)SmsReceiver 项目和 2.)Caller 项目答案

【问题标题】：How to Combine my two projects 1.)SmsReceiver projec and 2.)Caller project如何结合我的两个项目 1.)SmsReceiver 项目和 2.)Caller 项目
【发布时间】：2018-06-19 00:42:39
【问题描述】：

我不想在我的 android 中构建 SMS 触发的应用程序。我知道市场上有很多应用程序可以做到这一点，但我只想自己尝试一下。

我的 SMS 接收器项目和我的 Caller 项目一样有效。我想将它们组合为 1 个应用程序，但我不知道。有人可以帮帮我吗？

这是我从某处获得并测试工作的代码 sn-p..

调用者.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，安装后会拨打这个号码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app会报这个错误

呼叫转移应用程序意外停止工作。请再试一次。。

实际上我想做的是当有人向我的 android 发送短信时，我的 SmsReceiver 将提取发件人手机号码并回拨.. 发件人的号码存储在 sender 变量中..

我想做这样的事情

call(sender);

但这并不容易..我可以合并源代码而没有错误，但安装后我无法让它工作......

如果我能让它工作的话，这将是我的第一个 Android 应用程序.. ;)

这是我的清单文件：

        }

    }

}

我感觉代码是正确的，但我不知道如何解决这个问题..

我不知道如何遵循您的建议，因为我总是遇到错误。而是帮我检查我是否做得对..

这是我最新的代码。通话正常，但我的短信接收器没有。

我不知道怎么称呼我的

public class SmsReceiver extends BroadcastReceiver

在活动中，以便它监听传入的短信。

【解决方案1】：

您必须发布您的 logcat 错误以获取有关崩溃的帮助。不过打个电话也不是什么难事。我最初的猜测是您的 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？

确保发件人只存储电话号码。我相信是的。

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);  
}

用发件人替换号码，你应该都设置好了。

如果您想保留这两个活动，您可以执行以下操作。意图 callIntent = new Intent(this, Caller.class);
callIntent.putExtra("phoneNumber", sender);
开始活动（调用意图）；

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应用程序拨打该号码。或者您可以立即调用它。如果您只是在没有确认的情况下立即调用 #，请使用我的帖子中提到的第一种解决方案。

【讨论】：

我让短信接收器正常工作，但我应该如何调用 startActivity(callIntent); ?
我已添加编辑。我不知道您是想自动呼叫还是启动具有呼叫按钮的应用程序。但我提供了代码来启动呼叫者活动并发送电话号码
我已经在我目前的工作上面添加了编辑...关于这个的问题。 callIntent = new Intent(this, Caller.class); callIntent.putExtra("phoneNumber", sender);您告诉我不要使用第一个文件，但为什么要使用另一个文件中的 Caller 类？对不起，我无法得到它..
您的解决方案正是我试图帮助您实现的目标。我的代码模棱两可，因为您似乎坚持要保留 startActivity(callIntent)。你永远不需要我向你解释的调用活动。
谢谢。现在我有另一个关于电话特殊字符的问题。请在这里查看我的其他帖子stackoverflow.com/questions/9048833/…

【解决方案2】：

我终于解决了这个.. :)

这是基本代码..它将调用短信发送者..
