我是新的Android即时通讯创建一个应用程序,我有一个listfragment的问题,因为它显示的列表,但它重叠标题栏(我不得不添加边缘顶部来改变它),而且我使用抽屉和当我试图打开它也显示在选项抽屉上的列表时,letme会粘贴你的代码和图像,这样你就可以了解更多信息:

xml代码:

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:weightSum="1">

    <ListView
        android:layout_width="match_parent"
        android:layout_height="420dp"
        android:id="@android:id/list"
        android:layout_weight="0.82"
        android:layout_marginTop="60dp" />
</LinearLayout>

listFregment代码:

  public class FragmentoPrincipalChofer extends ListFragment {
    private List<ParseObject> mViaje;
    private ListView mLista;

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {



        View x = inflater.inflate(R.layout.fragmento_principal_chofer, container, false);
        mLista = (ListView)x.findViewById(android.R.id.list);
        return x;

    }

    @Override
    public void onResume() {
        super.onResume();

        //obtener pedido de taxi
       ParseQuery<ParseObject> query = ParseQuery.getQuery("Viaje");
        query.whereEqualTo("chofer", "prueba3");
        query.addDescendingOrder("createdAt");
        query.findInBackground(new FindCallback<ParseObject>() {
            public void done(List<ParseObject> viajes, com.parse.ParseException e) {
                if (e == null) {
                    mViaje=viajes;
                    String[] nombreUsuarios = new String[mViaje.size()];
                    int i=0;
                    for (ParseObject viaje : mViaje){

                        nombreUsuarios[i] = viaje.getString("cliente");
                        i++;
                    }

                   ArrayAdapter<String> adaptador = new ArrayAdapter<String>(getListView().getContext(),android.R.layout.simple_list_item_1,nombreUsuarios);
                  mLista.setAdapter(adaptador);


                } else {

                }
            }
        });

    }
}

主抽屉代码:

        //cargar fragment principal usuario

        FragmentoPrincipalChofer fragmento=(FragmentoPrincipalChofer) getSupportFragmentManager().findFragmentByTag("fragmento");
        if (fragmento==null){
            fragmento=new FragmentoPrincipalChofer();
            android.support.v4.app.FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
            transaction.add(android.R.id.content,fragmento,"fragmento");
            transaction.commit();

        }
        /*

        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);

    }

    @Override

2 个答案:

答案 0 :(得分:1)

您的问题是您使用此行将列表片段设置为整个视图ID

// android.R.id.content is the WHOLE screen of your Activity
transaction.add(android.R.id.content,fragmento,"fragmento");
transaction.commit();

在content_drawer_principal.xml中创建一个FrameLayout:

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

然后做:

transaction.add(R.id.list_content,fragmento,"fragmento");
transaction.commit();

<强>更新

这里的真正问题是,您告诉FragmentTransaction将FragmentoPrincipalChofer加载到android.R.id.content这是一个保留ID

  

android.R.id.content为您提供视图的根元素,而无需知道其实际名称/类型/ ID。

答案 1 :(得分:0)

撤消活动布局的顺序,将列表视图放在任何其他主要内容之前
