继续布局

Main的布局

<?xml version="1.0" encoding="utf-8"?><FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="fill_parent"    android:layout_height="wrap_content">    <include layout="@layout/buttons" />    <com.example.accc.flingswipe.SwipeFlingAdapterView        android:id="@+id/frame"        android:layout_width="match_parent"        android:layout_height="match_parent"        app:rotation_degrees="15.5"        tools:context=".MyActivity" /></FrameLayout>

其他的

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:layout_gravity="center_horizontal|bottom"    android:layout_marginBottom="20dp"    android:orientation="horizontal">    <ImageView        android:id="@+id/left"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center"        android:layout_margin="10dp"        android:background="@drawable/home_buttons_dislike"        android:onClick="left" />    <ImageView        android:id="@+id/info"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center"        android:layout_margin="10dp"        android:background="@drawable/home_buttons_info" />    <ImageView        android:id="@+id/right"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_margin="10dp"        android:background="@drawable/home_buttons_like"        /></LinearLayout>

还有一个

还有在drawable下面

home_buttons_dislike.xml

里面

home_buttons_info.xml
里面

home_buttons_like.xml

里面

material_card.xml

里面

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="@color/card_shadow" />
<corners android:radius="2dp" />
</shape>
</item>
<item android:bottom="2dp">
<shape android:shape="rectangle">
<solid android:color="@color/card_background" />
<corners android:radius="3dp" />
</shape>
</item>
</layer-list>

然后建立一个menu文件夹里面有俩个xml

global.xml

里面是

main.xml

里面是

values里面呢改变

strings.xml下面写填写

<string name="title_section1">Section 1</string>
<string name="title_section2">Section 2</string>
<string name="title_section3">Section 3</string>
<string name="navigation_drawer_open">Open navigation drawer</string>
<string name="navigation_drawer_close">Close navigation drawer</string>
<string name="action_example">Example action</string>
<string name="action_settings">Settings</string>
<declare-styleable name="SwipeFlingAdapterView">
<attr name="SwipeFlingStyle" format="reference" />
<attr name="rotation_degrees" format="float" />
<attr name="min_adapter_stack" format="integer" />
<attr name="max_visible" format="integer" />
</declare-styleable>
<color name="card_background">#ffffff</color>
<color name="card_shadow">#10000000</color>

还有填写一个XML

dimens.xml

里面是

最后还有values-w820dp名字的文件夹里面有一个Xml

dimens.xml

里面是

还有一些图片啊
这些最后的没法上传.都是杂杂的兄弟们大概都写了自己整把、
