java - 在 SlidingPaneLayout 实现中 Pane 始终打开

Question

我下面的代码的问题是默认情况下总是打开 Pane ，不知道为什么。显然，我不希望默认打开 Pane (子 Pane )。仅当用户单击 lv_schedule 时，该 Pane 才会打开。因此，当 fragment 加载时，我必须先滑出 Pane 才能看到 lv_schedule。

这是 XML:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.SlidingPaneLayout     xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/scheduledblocks_sliding_pane_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
>

<LinearLayout
    android:id="@+id/ll_left_pane_scheduled"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <ListView
        android:id="@+id/lv_schedule"
        android:layout_width="1000dp"
        android:layout_height="match_parent"
        android:layout_gravity="left"
        android:layout_marginRight="0dp"
        />

</LinearLayout>

<!-- Framelayout to display Fragments -->

<FrameLayout
    android:id="@+id/frame_container_scheduledblocksslidingpanedetailview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginLeft="20dp" />

这是 JAVA 文件:

public class Fragment_allScheduledBlocks extends Fragment implements
    View.OnClickListener, OnItemClickListener {

private Handler handler;

private ActionBarHelper mActionBar;

private Thread thread = new Thread();

public Fragment_allScheduledBlocks() {
}

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

    mLogger.printToLog(Constants.LOG_ENTRY,
            " onCreateView of Fragment_scheduled_blocks.java",
            Constants.TAG_ALL);

    v = inflater.inflate(R.layout.fragment_scheduled_blocks, container,
            false);

    mSlidingLayout = (SlidingPaneLayout) v
            .findViewById(R.id.scheduledblocks_sliding_pane_layout);
    mSlidingLayout.setPanelSlideListener(new SliderListenerSchBlocks());
    mSlidingLayout.openPane();


    lv_scheduled = (ListView) v.findViewById(R.id.lv_scheduled);
    lv_scheduled.setOnItemClickListener(this);

    mActionBar = createActionBarHelper();
    mActionBar.init();

    return v;
}


/**
 * This panel slide listener updates the action bar accordingly for each
 * panel state.
 */
private class SliderListenerSchBlocks extends
        SlidingPaneLayout.SimplePanelSlideListener {
    @Override
    public void onPanelOpened(View panel) {
        mActionBar.onPanelOpened();
        Log.v(Constants.TAG, "in onPanelOPened inside SliderListener");
        getActivity().setTitle("LISTVIEW BLOCKS");

        mPrefs.printAllMySharedPrefs(getActivity().getApplicationContext());
    }

    @Override
    public void onPanelClosed(View panel) {
        mActionBar.onPanelClosed();
        Log.v(Constants.TAG, "in onPanelClosed inside SliderListener");
        mPrefs.printAllMySharedPrefs(getActivity().getApplicationContext());
    }

    @Override
    public void onPanelSlide(View panel, float slideOffset) {
        // TODO Auto-generated method stub
        super.onPanelSlide(panel, slideOffset);
    }
}




@Override
public void onClick(View v) {
    // TODO Auto-generated method stub

}

private class ActionBarHelper {
    public void init() {
    }

    public void onPanelClosed() {
    }

    public void onPanelOpened() {
    }

    public void onFirstLayout() {
    }

    public void setTitle(CharSequence title) {
    }
}

/*
 * Create a compatible helper that will manipulate the action bar if
 * available.
 */
private ActionBarHelper createActionBarHelper() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
        // return new ActionBarHelperICS();
        return new ActionBarHelper();
    } else {
        return new ActionBarHelper();
    }
}

}

如果您想通过导航图标打开 Pane ，则可以使用此:

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

    layout = (SlidingPaneLayout) findViewById(R.id.sliding_pane_layout);

    getToolbar().setNavigationIcon(R.drawable.ic_menu_white_24dp);
    getToolbar().setNavigationOnClickListener(this); 
}

@Override
public void onClick(View view) {
    if (layout != null) {
        if (!layout.isOpen()) {
            layout.openPane();
        } else {
            layout.closePane();
        }
    }
}

干杯，编码愉快。 ;)
