Question

这是这样，但现在遵循代码块：

    public View onCreateView(LayoutInflater inflater, ViewGroup container,    Bundle savedInstanceState)
         {
        myView = inflater.inflate(R.layout.first_layout, container, false);

         tv.setOnClickListener(
            new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                    tv = (TextView) myView.findViewById(R.id.textView);
                    Intent i = new Intent();
                    i.setClass(getActivity(), Second_Fragment.class);
                    startActivity(i);

                }
                 });

           return myView;
        }

XML代码：

    <ImageView
        android:src="@drawable/processor"
        android:layout_width="150dp"
        android:layout_height="80dp"
        android:id="@+id/imageView"
        android:layout_weight="2" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:text="Processor"
        android:textSize="25dp"
        android:id="@+id/textView2"
        android:layout_weight="2"
        android:clickable="true"/>
    </TableRow>

错误代码：

Answer 1

假设您的startActivity()是片段，则无法通过Second_Fragment.class附加片段。请参阅此如何创建片段http://developer.android.com/guide/components/fragments.html

从文档中，添加要分段的视图：

<FrameLayout 
     android:id="@+id/second_fragment"
     android:layout_width="wrap_content"   
     android:layout_height="match_parent" />

然后通过FragmentManager

将其附加到onClick中的此视图

// Create new fragment and transaction
Fragment secondFragment = new SecondFragment();
FragmentTransaction transaction = getFragmentManager().beginTransaction();

// Add the fragment to the second_fragment view with this fragment,
// and add the transaction to the back stack
transaction.add(R.id.second_fragment, secondFragment);
transaction.addToBackStack(null);

// Commit the transaction
transaction.commit();

Answer 2

首先：你没有开始调用片段：

Intent i = new Intent();
i.setClass(getActivity(), Second_Fragment.class);
startActivity(i);

该方法的名称很明确：startActivity（i）;因此，您应该学习如何启动片段而不是开始活动！

第二：把：

tv = (TextView) myView.findViewById(R.id.textView);

在setOnClickListener（...）;

之前

Answer 3

您可以在Activity和片段中使用界面每当你点击片段jst中的textview时，通过接口将数据发送到活动，并从活动中更新片段为此你必须使用onAttach（）方法

使用TextView的onClick转到包含片段
