曦笑大海 通过本文主要向大家介绍了比例阀的功能,足趾功能比例,手指功能比例,脚趾功能比例,肝功能白 球比例降低等相关知识,希望对您有所帮助,也希望大家支持linkedu.com www.linkedu.com
前言：基于RxPaparazzo的图片裁剪，图片旋转、比例放大|缩小。
效果：
开发环境：AndroidStudio2.2.1+gradle-2.14.1
涉及知识：
1.Material Design
（CardView+CoordinatorLayout+AppBarLayout+NestedScrollView+CollapsingToolbarLayout+Toolbar+FloatingActionButton）使用
2.butterknife注解式开发
3.基于RxJava+RxAndroid的RxPaparazzo使用
引入依赖：
compile 'com.android.support:appcompat-v7:24.+'
//RxPaparazzo 拍照&相册
// compile "com.github.miguelbcr:RxPaparazzo:0.4.2-2.x"
compile ("com.github.miguelbcr:RxPaparazzo:0.5.2-2.x") {
exclude module: 'okhttp'
exclude module: 'okio'
}
compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
compile 'com.android.support:cardview-v7:24.+'
// compile 'com.android.support:customtabs:24.+'
compile 'com.android.support:design:24.+'
compile 'com.jakewharton:butterknife:7.0.1'
