从现在开始，在博客园上记录自己遇到的所有android开发问题：

布局文件内容：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/container"
    android:orientation="horizontal"
    android:baselineAligned="false" 
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <fragment    android:name="com.Victory.myfragment.LeftFragment"  
        android:id="@+id/leftFragmentID"  
        android:layout_width="0dip"  
        android:layout_height="match_parent"  
        android:layout_weight="1" ></fragment>  
    <fragment   android:name="com.Victory.myfragment.RightFragment"
        android:id="@+id/rightFragmentID"  
        android:layout_width="0dip"  
        android:layout_height="match_parent"  
        android:layout_weight="1" ></fragment>  
    
</LinearLayout>
