尝试调用虚函数 [英] Attempt to invoke virtual method
问题描述
我试图得到一些 LinearLayouts
在我的 onCreateView
,但我的应用程序崩溃,出现以下消息:
23430-23430 /? W / System.err的:显示java.lang.NullPointerException:尝试在空对象引用调用虚拟方法android.view.View android.view.View.findViewById(INT)'
下面是code:

这是一个纯粹的片段

不包含此片段
。我是不是做错了?如若片段
永远是活动中的

您膨胀的布局。的意见属于充气布局。因此,使用视图对象初始化意见 onCreateView
片段是由Acitvity托管
您可以在 onActivityCreated
使用 getView
和初始化意见
初始化您的TextView的也在 onCreateView
。由于AsyncTask的是,你可以更新UI有一个内部类
声明
RobotoTextView date_widget2;
作为实例变量
然后在onCreateView
date_widget2 =(RobotoTextView)rootView.findViewById(R.id.date02);
I am trying to get some LinearLayouts
in my onCreateView
but my App is crashing with the following message:
23430-23430/? W/System.err﹕ java.lang.NullPointerException: Attempt to invoke virtual method 'android.view.View android.view.View.findViewById(int)' on a null object reference
Here is the code:
@Override

This is a pure Fragment
class. The Activity
which calls this Fragment
does not contain this Fragment
. Am I doing it wrong? Should the Fragment
always be within the Activity
?

Change to

card02 = (LinearLayout) rootView.findViewById(R.id.card02);
card03 = (LinearLayout) rootView.findViewById(R.id.card03);
card04 = (LinearLayout) rootView.findViewById(R.id.card04);
card05 = (LinearLayout) rootView.findViewById(R.id.card05);
card06 = (LinearLayout) rootView.findViewById(R.id.card06);
You inflate a layout. the views belong to the inflated layout. So use the view object to initialize views in onCreateView
Fragment is hosted by a Acitvity
You can use getView
in onActivityCreated
and initialize views
Initialize your TextView's also in onCreateView
. Since Asynctask is a inner class you can update ui there
Declare
RobotoTextView date_widget2;
as instance variable
Then in onCreateView
date_widget2= (RobotoTextView) rootView.findViewById(R.id.date02);
