Question

我有滑动窗格布局

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

    <fragment
        android:id="@+id/first_fragment"
        android:layout_width="@dimen/first_pane_width"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        class="com.example.example.FirstFragment"
        tools:layout="@layout/fragment_first" />

    <fragment
        android:id="@+id/second_fragment"
        android:layout_width="@dimen/second_pane_width"
        android:layout_weight="1"
        android:layout_height="match_parent"
        class="com.example.example.SecondFragment"
        tools:layout="@layout/fragment_second`enter code here`" />

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

这是我的onCreate方法：

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

    slidingPaneLayout = (SlidingPaneLayout) findViewById(R.id.slidingPaneLayout);
    slidingPaneLayout.setPanelSlideListener(this);
    slidingPaneLayout.setParallaxDistance(PARALLAX_DISTANCE);
    slidingPaneLayout.setShadowDrawable(getResources().getDrawable(R.drawable.shadow));

    secondFragment = (SecondFragment) getFragmentManager().findFragmentById(R.id.second_fragment);
    firstFragment = (FirstFragment) getFragmentManager().findFragmentById(R.id.first_fragment);

    if (savedInstanceState == null) {
        firstFragment.selectItem(0);
        if (slidingPaneLayout.isSlideable()) {
            slidingPaneLayout.openPane();
            onPanelOpened(null);
        }   
    }
    if (slidingPaneLayout.isSlideable()) Log.d(TAG, "isSlideable");

但是slidingPaneLayout.isSlideable（）总是返回false。我试图在手机和模拟器（Nexus 7）上运行应用程序，但它总是返回相同的结果。在调试模式下，mCanSlide变量（slidingPaneLayout对象）始终为false。

是的，有人告诉我，我做错了什么？感谢。

检查

isSlaydeble=false;

slidingPaneLayout = (SlidingPaneLayout) findViewById(R.id.dl_menu);
slidingPaneLayout.setPanelSlideListener(new SlidingPaneLayout.PanelSlideListener() {
            @Override
            public void onPanelSlide(View view, float v) {
                isSlaydeble=true;
            }

            @Override
            public void onPanelOpened(View view) {
            }

            @Override
            public void onPanelClosed(View view) {
            }
        });

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

SlidingPaneLayout isSlideable（）方法不起作用
