Android窗格活动容器的库背景

Question

我是PanesLibrary的新用户，但我不知道如何在应用程序启动时在后台显示个人布局。该代码类似于github上的示例，没有自动生成的片段和示例片段：

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setPaneSizer(new ExamplePaneSizer()); //inner class like on the github example
    // Lets setup a menu and a first pane!
    if (savedInstanceState == null) {
        Fragment menu = new CatFragment(); //show list of categories
        setMenuFragment(menu);
    }
}

这是ExampleActivity:的布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".SandboxActivity" >
<com.mapsaurus.paneslayout.PanesLayout
    android:id="@+id/panes"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1" 
    >
    <TextView
        android:id="@+id/textView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="Some Text"
        android:textAppearance="?android:attr/textAppearanceLarge" />
</com.mapsaurus.paneslayout.PanesLayout>

问题是TextView没有显示。谢谢

我解决了。只需添加一个新的片段

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setPaneSizer(new ExamplePaneSizer());
    // Lets setup a menu and a first pane!
    if (savedInstanceState == null) {
        Fragment menu = new CatFragment();
        Fragment instr = new InstructionFragment();
        setMenuFragment(menu);
        addFragment(menu, instr);
