在activityA，

final Intent conditionalIntent = new Intent(this,ConditionalPolicyEntry.class); 
     btn_ok.setOnClickListener(new View.OnClickListener() 
      { 
       @Override 
       public void onClick(View v) 
       { 

        conditionalIntent.putExtra("user_id",1); 
        startActivity(conditionalIntent); 
       } 
      });

在activityB，

Bundle extrasFromCondition = getIntent().getExtras(); 
    myPolicy.setID(extrasFromCondition.getInt("user_id")); // line 41

PS：错误是通过捆绑获取函数，其后，每当我把//。认为我无法传递数据。

策略类如下：

public class Policy{ 
int ID; 
int user_type; 
public int getID() 
{ 
    return ID; 
} 
public void setID(int iD) { 
    this.ID = iD; 
} 

public int getUser_type() { 
    return user_type; 
} 
public void setUser_type(int userType) { 
    this.user_type = userType; 
}}

onCreate方法的显示代码？ – Rasel

在第41行检查也有一些是空：

at com.acdroid.activityclasses.ConditionalPolicyEntry.onCreate(ConditionalPolicyEntry.java:41)

，或者如果你能证明代码...

你得到空指针例外请检查

ConditionalPolicyEntry.onCreate（ConditionalPoli cyEntry.java:41）

Line 41-> extrasFromCondition = getIntent（）。getExtras（）;它从前面的活动捕获额外的捆绑...并且我已经把这样的额外内容 - > conditionalIntent.putExtra（“user_id”，user_id）; – Renegade

你会不会我你代码更多的地方你设置的价值，并得到的价值，因为这里可能是意图/包变空 – Pratik

在activityA中，我将常量值放在bundle中，并通过intent传递给activityB“conditionalIntent.putExtra（”user_id“，1）; startActivity（conditionalIntent）;“ 在activityB中，我使用此代码将其重置为”extrasFromCondition = getIntent（）。getExtras（）;“ – Renegade

有在你的代码空指针文件ConditionalPolicyEntry.java行号41

com.acdroid.activityclasses.ConditionalPolicyEntry.onCreate(ConditionalPolicyEntry.java:41)

conditionalIntent.putExtra("user_id","1"); 
startActivity(conditionalIntent); 

myPolicy.setID(Integer.parseInt(extrasFromCondition.getString("user_id")));

什么myPolicy.if它是一种观点则方法SETID，没有设置ID

Rasel >>它只是一个像表格豆携带数据 – Renegade

现在是什么状态？ – Rasel

仍然无法弄清.. – Renegade

既然你说过“我已经在上面添加了代码。我认为这是putExtras问题，但我错了。我可以使用myPolicy.setID（...）上面的Log.i（）打印捆绑数据。 - “

和错误是在下面的一行：

myPolicy.setID(extrasFromCondition.getInt("user_id")); // line 41

可以得出的唯一结论是参考myPolicy为null，你在哪里分配myPolicy
