整體效果如下：

實現方式：通過Activity的FragmentManage去實現

首先要先去建立兩個佈局檔案，分別為pay.xml和income.xml,代表兩個片段的內容，下面我只是貼了其中一個佈局檔案的內容

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:background="#445543"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    

</LinearLayout>
 

簡單起見我只是把這兩個佈局檔案的background給設定了一下，用於區分。

然後寫兩個類，分別為PayFragment和IncomeFragment，讓它們都去繼承Fragment類，重寫onCreateView方法，

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = View.inflate(getActivity(), R.layout.pay, null);
return view;
}

Inflate()作用就是將xml定義的一個佈局找出來，inflate方法中間那個引數是制定的佈局檔案。

完成上面的工作後我們就該總佈局檔案的編寫了：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".SecondActivity" >
<LinearLayout 
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">
  <Button 
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:layout_weight="1"
     android:id="@+id/pay"
     android:text="支出"/>
  <Button 
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:layout_weight="1"
     android:id="@+id/income"
     android:text="收入"/>
</LinearLayout>
<FrameLayout 
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_weight="1"
    android:id="@+id/fl">
    
</FrameLayout>
</LinearLayout>
