在这里需要设置一个权限：
uses-permission android:name=“android.permission.VIBRATE”
然后来看一下，mainactivity.xml中的代码：

<?xml version="1.0" encoding="utf-8"?> 

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <!--摇一摇中心图片-->
    <TextView
        android:id="@+id/tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:textSize="30sp"
        android:textColor="@color/colorRed"
        android:text="@string/app_c"/>
    <LinearLayout
        android:gravity="center"
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true">
        <!--顶部的横线和图片-->
        <LinearLayout
            android:gravity="center_horizontal|bottom"
            android:id="@+id/main_linear_top"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">
            <ImageView
                android:src="@mipmap/top"
                android:id="@+id/main_shake_top"
                android:layout_width="wrap_content"
                android:layout_height="100dp"/>
            <ImageView
                android:background="@mipmap/line"
                android:id="@+id/main_shake_top_line"
                android:layout_width="match_parent"
                android:layout_height="5dp"/>
        </LinearLayout>

        <!--底部的横线和图片-->
        <LinearLayout
            android:gravity="center_horizontal|bottom"
            android:id="@+id/main_linear_bottom"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical">

            <ImageView
                android:background="@mipmap/line"
                android:id="@+id/main_shake_bottom_line"
                android:layout_width="match_parent"
                android:layout_height="1dp"/>
            <ImageView
                android:src="@mipmap/bottom"

                android:layout_height="100dp"/>

        </LinearLayout>
    </LinearLayout>
    <Button
        android:id="@+id/but"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="你点我"/>
</RelativeLayout>

mipmap-hdpi文件夹下需要放入maintivity.xml相对应的图片，这里就不多演示了

因为需要播放音乐所以这里需要建一个raw文件夹，这里面是放音乐资源的，也不过多演示了
values文件夹下的colors.ml与Strings.xml分别要写的代码：
colors.xml是设置颜色用的
在这里插入图片描述
String.xml可以放入字符串：
在这里插入图片描述
接下来就是最为重要的mainactivity里面的代码：
