開放ListFragment

Question

我嘗試用碎片的工作中，我創建BusModelActivity這種延伸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); 
} 

}

，但我無法從其他活動找到它

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

我得到：

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? 

但是當我嘗試添加到AndroidManifest文件它找不到我的活動。如何從活動運行ListFragment？

Answer 1

看到你可以附加一個片段到一個活動。

像爲： -

FragmentManager fm = getFragmentManager(); 

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

然後導航一樣，具體如下： -

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

和活動應該存在於AndroidManifest.xml
