galleryfinal 实现Android图片单选/多选、拍照、裁剪、压缩。视频选择和录制。

RxGalleryFinal是一个android图片/视频文件选择器。其支持多选、单选、拍摄和裁剪，主题可自定义，无强制绑定第三方图片加载器。

1.首先加入权限

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

2.在module gradle中项目依赖代码：

compile 'cn.finalteam.rxgalleryfinal:library:0.0.1'

//支持以下主流图片加载器，开发者自行选择
  compile 'com.squareup.picasso:picasso:2.5.2'
  compile 'com.facebook.fresco:fresco:0.12.0'
  compile 'com.github.bumptech.glide:glide:3.7.0'
  compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'

3.在fest加入所需的activity

<application
      ...
      android:theme="@style/Theme_Light">
  <activity
      android:name="cn.finalteam.rxgalleryfinal.ui.activity.MediaActivity"
      android:screenOrientation="portrait"
      android:exported="true"
      android:theme="@style/Theme_Light.Default"/>
  <activity
      android:name="com.yalantis.ucrop.UCropActivity"
      android:screenOrientation="portrait"
      android:theme="@style/Theme_Light.Default"/>
</application

4.java代码

RxGalleryFinal
                .with(PhotoActivity.this)
                .image()
                .radio()
                .crop()
                .imageLoader(ImageLoaderType.FRESCO)
                .subscribe(new RxBusResultSubscriber<ImageRadioResultEvent>() {
                    @Override
                    protected void onEvent(ImageRadioResultEvent imageRadioResultEvent) throws Exception {
                        //图片选择结果
                        simpleDraweeView.setImageURI("file://" + imageRadioResultEvent.getResult().getCropPath());
//                        simpleDraweeView.setImageURI(imageRadioResultEvent.getResult().getOriginalPath());
                        imageView.setImageURI(Uri.parse(imageRadioResultEvent.getResult().getOriginalPath()));
                    }
                })
                .openGallery();
