Question

我正在开发一个应用程序，其中我有一个片段类，另一个是MainActivity类。在MainActivity.java中，我动态加载Fragment类。现在，当加载Fragment类时，我想在Fragment类视图上放置一个Onclick事件。

我的代码段如下。的 MainHandlerFragment.java

public class MainHandlerFragment extends Fragment{
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.home_detail, container, false);
        return view;
    }

    public void navigateToAnotherActivity(){    // I am not able to call this method
       startActivity(new Intent(getActivity(),  OrganizationActivity.class).putExtra("User",user));
   }
}

home_detail.xml

  <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/home_top_layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/shadow_layout"
    android:padding="6dip"
    android:layout_margin="10dp"
    android:onClick="navigateToAnotherActivity()"       // I am not able to call this method
    >

当调用动态加载的片段视图时，无论如何都会触发onclick

Answer 1

尝试这种方式：

 RelativeLayout layout = (RelativeLayout)view.findViewById(R.id.home_top_layout);

 layout.setOnClickListener(new View.OnClickListener()
{
    @Override
    public void onClick(View arg0)
    {
     startActivity(new Intent(getActivity(),  OrganizationActivity.class).putExtra("User",user));
     }
});

并删除android:onClick="navigateToAnotherActivity()"

Answer 2

首先，您没有在XML中正确调用函数，更改

android:onClick="navigateToAnotherActivity()"

到

android:onClick="navigateToAnotherActivity"

这样做你也应该将你的功能改为

public void navigateToAnotherActivity(View v)

以便被召唤。

无论如何，Android不鼓励这样做，它可能会成为一种不推荐的调用函数的方式，所以我建议你尝试以下方法：

RelativeLayout rl = (RelativeLayout)findViewById(R.id.home_top_layout);

rl.setOnClickListener(new View.OnClickListener()
{
    public void onClick(View v) {
    navigateToAnotherActivity();
}
});

Answer 3

 public class MainHandlerFragment extends Fragment
 {
   @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.home_detail, container, false);
        public void navigateToAnotherActivity()
           {    // I am not able to call this method 
                startActivity(newIntent(getActivity(),OrganizationActivity.class).putExtra("User",user));
        }
    return view;
   }

}

Answer 4

试试这个

@Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.home_detail, container, false);

        RelativeLayout rl = (RelativeLayout)view.findViewById(R.id.home_top_layout);

         rl.setOnClickListener(new View.OnClickListener()
         {
            public void onClick(View v) {
            startActivity(new Intent(getActivity(),  OrganizationActivity.class).putExtra("User",user));
          }
        });
        return view;
    }
