Question

我尝试使用片段，我创建了BusModelActivity，例如扩展ListFragment

public class BusModelsActivity extends ListFragment {

String data [] = new String[]{"1","2","3","4"};

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    ArrayAdapter<String> adapter =  new ArrayAdapter<String>(getActivity(),android.R.layout.simple_list_item_1,data);
    setListAdapter(adapter);
}

}

但我无法从其他活动

导航到它

Intent intent = new Intent(BusSearchParamActivity.this,BusModelsActivity.class);
startActivity(intent);

我明白了：

android.content.ActivityNotFoundException: Unable to find explicit activity class {ru.avtobus66.finder_transport/ru.avtobus66.finder_transport.BusModelsActivity};
have you declared this activity in your AndroidManifest.xml?

但是当我尝试添加到AndroidManifest文件时它无法找到我的活动。如何从活动中运行ListFragment？

Answer 1

看到您可以将片段附加到活动。

如： -

FragmentManager fm = getFragmentManager();  

  if (fm.findFragmentById(android.R.id.content) == null) {  
   BusModelsActivity list = new BusModelsActivity ();  
   fm.beginTransaction().add(android.R.id.content, list).commit();  
  }

然后导航如下： -

Intent intent = new Intent(BusSearchParamActivity.this,YourActivity.class);
startActivity(intent);

该活动应该出现在AndroidManifest.xml

中

从其他活动中打开ListFragment
