为什么我的应用程序在Android中的ImageView点击时会强制从一个片段移动到另一个片段？

单击

ImageView

，我正试图从

mycontacts extends Fragment

移动到

tasks extends Fragment

。我的ImageView位于使用SimpleAdapter生成的

列表视图中。我的布局id如下：
R.id.tasky
用于任务片段，
R.id.mycontacts
用于mycontacts片段。我的代码和错误日志如下。由于我是新来的碎片，请一步一步地向我解释

支原体

 purple.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
     android.app.FragmentTransaction t = getActivity().getFragmentManager().beginTransaction();
        Fragment fragment = new tasks();
        FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.replace(R.id.tasky, fragment);
        fragmentTransaction.addToBackStack(null);
        fragmentTransaction.commit();
}
});

错误日志：

您的mycontacts
片段
xml没有id为
R.id.tasky
的
ViewGroup
。您可以使用接口作为对活动的回调，然后用另一个替换容器中现有的片段

您可以找到代码片段@


在文档中的示例中，在
列表项上有
列表片段
，单击
将值传达给
活动
。然后在活动中，将现有片段替换为新片段，并将值传递给新片段

类似地，在
ImageView
上单击“与活动通信”，然后从“活动”中替换容器中的相应片段。
您没有id为
