ActionBar - PullToRefresh

Question

我正在开发一个可以查看BusStop时间表的应用程序。用户可以使用ActionBar PullToRefresh（库）进行刷新。我的应用程序还启用了KitKat上的半透明状态栏。

现在ActionBar Overlay（通常应该与动作栏重叠）现在向上移动。

我该如何解决？

祝你好运！

Answer 1

我所做的是为pull-to-refresh布局创建自定义标题布局。我只是复制了原来的一个，添加了状态栏的高度，通常为25dp，并添加了25dp的顶部填充。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="73dp"
    android:paddingTop="25dp" >

    <FrameLayout
        android:id="@id/ptr_content"
        android:layout_width="match_parent"
        android:layout_height="73dp" >

        <TextView
            android:id="@id/ptr_text"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="center"
            android:textAppearance="?android:attr/textAppearanceMedium" />
    </FrameLayout>

    <fr.castorflex.android.smoothprogressbar.SmoothProgressBar
        android:id="@id/ptr_progress"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:minHeight="@dimen/ptr_progress_bar_stroke_width" />

</RelativeLayout>

现在，在设置拉动刷新布局时设置布局：

ActionBarPullToRefresh.from(getActivity()).listener(new OnRefreshListener() {

    @Override
    public void onRefreshStarted(View view) {
        refresh();
    }

}).headerLayout(R.layout.header).build()).setup(ptrLayout);

试试这个。

RES /布局/ activity_main.xml中

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:id="@+id/container"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  tools:context="com.swipetorefresh.MainActivity"
  tools:ignore="MergeRootFrame" />

RES /布局/ fragment_main.xml

<android.support.v4.widget.SwipeRefreshLayout           
   xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:id="@+id/container"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   tools:ignore="MergeRootFrame" >

   <ListView
       android:id="@android:id/list"
       android:layout_width="match_parent"
       android:layout_height="match_parent" />

</android.support.v4.widget.SwipeRefreshLayout>

MainActivity.java

  public class MainActivity extends Activity {

   @Override
 protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

if (savedInstanceState == null) {
    getFragmentManager().beginTransaction()
            .add(R.id.container, new PlaceholderFragment()).commit();
}
}

  public static class PlaceholderFragment extends ListFragment implements OnRefreshListener {

private SwipeRefreshLayout mSwipeRefreshLayout;

private static final int LIST_ITEM_COUNT = 5;
private int mOffset = 0;

private ArrayAdapter<String> mListAdapter;

public PlaceholderFragment() {
}

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

    // Configure the swipe refresh layout
    mSwipeRefreshLayout = (SwipeRefreshLayout) rootView.findViewById(R.id.container);
    mSwipeRefreshLayout.setOnRefreshListener(this);
    mSwipeRefreshLayout.setColorScheme(
            R.color.swipe_color_1, R.color.swipe_color_2,
            R.color.swipe_color_3, R.color.swipe_color_4);

    // Put the first batch of countries in the list
    mListAdapter = new ArrayAdapter<String>(
            getActivity(),
            android.R.layout.simple_list_item_1,
            android.R.id.text1,
            getCountries(mOffset));

    setListAdapter(mListAdapter);

    return rootView;
}

private List<String> getCountries(int offset) {
    ArrayList<String> countriesList = new ArrayList<String>();
    for(int i=0; i<LIST_ITEM_COUNT;i++){
        countriesList.add(COUNTRIES[offset+i]);
    }

    mOffset = offset + LIST_ITEM_COUNT;
    return countriesList;
}

@Override
public void onRefresh() {
    // Start showing the refresh animation
    mSwipeRefreshLayout.setRefreshing(true);

    // Simulate a long running activity
    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
           updateCountries();
        }
    }, 5000);
}



private void updateCountries() {

    // Add the next batch of countries to the list
    mListAdapter.addAll(getCountries(mOffset));

    // Signify that we are done refreshing
    mSwipeRefreshLayout.setRefreshing(false);
}



private static final String[] COUNTRIES = {"Afghanistan",
    "Albania", "Algeria", "American Samoa", "Andorra", "Angola",
