Android 實現操作功能列表

效果圖：

實現思路：

1.佈局文件 layout_user.xml。頁面由兩部分組成，頂部標題，下面一個ListView控件。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:padding="5dp">

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:padding="0dp">

        <ImageView
            android:layout_width="32dp"
            android:layout_height="32dp"
            android:src="@mipmap/user"></ImageView>

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="5dp"
            android:text="個人中心"
            android:textSize="16dp" />
    </LinearLayout>

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:padding="5dp">

        <ListView
            android:id="@+id/menu_list"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    </LinearLayout>

</LinearLayout>

2.主要就是設置這個ListView控件的數據和樣式。
