意图功能无法正常工作

-4

即时通讯面临的一个问题是，即时通过putExtra从电话活动发送线路号码，并收到拨号活动的值。 getIntent函数第一次收到正确的值，但在第二次时，他无法收到正确的值。第1个谷值第2次出现。意图功能无法正常工作

这是'Phone.java'类的所有代码吗？ –

检查你是否在第二次传递相同的'sPhoneNo和nFreeLineNo' – SathishKumar

你是否在AndroidManifest的DialPad Activity中有任何标志，如SINGLE_TOP或smth else。如果是这样的创建可能不会被调用。在这种情况下，您必须重写activity中的onNewIntent（）方法。 –

尝试创建一个Bundle对象，然后通过intent.putExtras（束）传递，这是通过一个意图通过额外的正确方法（我明白nFreeLineNo是一个int和sPhoneNo一个字符串）：

Intent intent = new Intent(Phone.this , DialPad.class); 
intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); 
Bundle b = new Bundle(); 
b.putInt("LineNo", nFreeLineNo); 
b.putString("PhoneNo", sPhoneNo); 
intent.putExtras(b); 
startActivity(intent);

另外，在DialPa d getExtras这样的：

Intent intent = getIntent(); 
Bundle b = intent.getExtras(); 
//Make sure you passed a bundle 
if (b != null){ 
    m_nLineNo = b.getInt("LineNo"); 
    m_sPhoneNo = b.getString("PhoneNo"); 
}else{ 
    //didnt pass bundle, Do what you want 
}

希望我帮你，我也有这个问题，解决了这个方式

如果不帮你，请从logcat的POST错误堆栈跟踪

不是它不工作 – user3136235

请发布stacktrace然后。否则，我忍不住 – BamsBamx

这是一个无用的答案。其他的东西已经是'Bundle'了。你可以简单地使用'putExtra（）'（这个OP已经在做）来添加原语和'String'。把这些额外的东西放到一个额外的Bundle中，然后调用putExtras（）将这个Bundle中的数据复制到额外的Bundle中，只是简单的开销，并不能完成任何事情。最后，它和OP已经做的完全一样（这就是为什么这个答案不能解决他的问题）。 –

Phone活动启动DialPad活动使用Intent.FLAG_ACTIVITY_REORDER_TO_FRONT。这意味着如果任务堆栈中已有活动（未完成）DialPad实例，则该活动实例将简单地移到前面（活动堆栈的顶部）。在这种情况下，onCreate()将不会在DialPad上被调用，因为它不会重新创建活动。相反onNewIntent()将被调用。您尚未覆盖DialPad中的此方法，因此您不会看到此方法调用。

既然你是在onCreate()提取的意图演员LineNo和PhoneNo，你永远只使用您从第一Intent获取数据。这正是你所看到的问题。

为了解决这个问题，覆盖onNewIntent()并提取从在您在onNewIntent()收到Intent参数传递的额外LineNo和PhoneNo。
