ok封装可参考之前博客

1.先导包

compile 'com.google.code.gson:gson:2.8.2'
compile 'com.jcodecraeer:xrecyclerview:1.3.2'
compile 'com.android.support:recyclerview-v7:27+'
compile 'com.squareup.okhttp3:okhttp:3.9.0'
compile 'com.squareup.okio:okio:1.11.0'
compile 'com.squareup.okhttp3:logging-interceptor:3.9.0'
compile 'com.github.bumptech.glide:glide:3.5.2'
implementation 'com.jakewharton:butterknife:8.8.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'
compile 'com.amap.api:location:latest.integration'

2.添加权限

<uses-permission android:name="android.permission.INTERNET" />

3.编写xml

在values文件夹下编写     dimens

<resources>
    <dimen name="left_space_pading">12dp</dimen>
</resources>
编写attrs  用来做自定义view的组合控件

<declare-styleable name="MyApp">
    <attr name="title_text" format="string"></attr>
    <attr name="title_color" format="color"></attr>
    <attr name="title_text_right" format="string"></attr>
    <attr name="title_color_right" format="color"></attr>
</declare-styleable>
