GalleryFinal 接入

图片选择器使用场合比较多，第三方的框架也有不少，这个算是比较优秀的

接入方法：

gradle

compile 'cn.finalteam:galleryfinal:1.4.8.7'

compile 'com.android.support:support-v4:23.1.1'

application

private void initGalleryFinal(){

    ThemeConfig theme = new ThemeConfig.Builder()
            .setTitleBarBgColor(Color.rgb(0xFF, 0x57, 0x22))
            .setTitleBarTextColor(Color.BLACK)
            .setTitleBarIconColor(Color.BLACK)
            .setFabNornalColor(Color.RED)
            .setFabPressedColor(Color.BLUE)
            .setCheckNornalColor(Color.WHITE)
            .setCheckSelectedColor(Color.BLACK)
            .setIconBack(R.mipmap.ic_action_previous_item)
            .setIconRotate(R.mipmap.ic_action_repeat)
            .setIconCrop(R.mipmap.ic_action_crop)
            .setIconCamera(R.mipmap.ic_action_camera)
            .build();
    //配置功能
    FunctionConfig functionConfig = new FunctionConfig.Builder()
            .setEnableCamera(true)
            .setEnableEdit(false)
            .setEnableCrop(false)
            .setEnableRotate(true)
            .setCropSquare(true)
            .setEnablePreview(true)
            .build();

    initImageLoader(context);

    CoreConfig coreConfig = new CoreConfig.Builder(this, new UILImageLoader(), theme)
            .setFunctionConfig(functionConfig)
            .setPauseOnScrollListener(new UILPauseOnScrollListener(false, true))
            .build();
    GalleryFinal.init(coreConfig);
}

private void initImageLoader(Context context) {
    // This configuration tuning is custom. You can tune every option, you may tune some of them,
    // or you can create default configuration by
    //  ImageLoaderConfiguration.createDefault(this);
    // method.
    ImageLoaderConfiguration.Builder config = new ImageLoaderConfiguration.Builder(context);
    config.threadPriority(Thread.NORM_PRIORITY - 2);
    config.denyCacheImageMultipleSizesInMemory();
    config.diskCacheFileNameGenerator(new Md5FileNameGenerator());
    config.diskCacheSize(50 * 1024 * 1024); // 50 MiB
    config.tasksProcessingOrder(QueueProcessingType.LIFO);
    config.writeDebugLogs(); // Remove for release app

    // Initialize ImageLoader with configuration.
    ImageLoader.getInstance().init(config.build());
}

    }
}

在使用的activity中调用

GalleryFinal.openGalleryMuti(REQUEST_CODE_GALLERY, MAX_IMG, mOnHanlderResultCallback);

实现

private GalleryFinal.OnHanlderResultCallback mOnHanlderResultCallback = new GalleryFinal.OnHanlderResultCallback() {
    @Override
    public void onHanlderSuccess(int reqeustCode, 

   @Override
    public void onHanlderFailure(int requestCode, String errorMsg) {
        Toast.makeText(GoodEvaluateActivity.this, errorMsg, Toast.LENGTH_SHORT).show();
    }
