步骤

1.添加依赖

//GalleryFinal - 图片选择
compile 'cn.finalteam:galleryfinal:1.4.6'
//UIL
compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'

2.初始化

package com.qr.galleryfinaldemo;

import android.app.Application;

import com.nostra13.universalimageloader.core.ImageLoaderConfiguration;

import cn.finalteam.galleryfinal.BuildConfig;
import cn.finalteam.galleryfinal.CoreConfig;
import cn.finalteam.galleryfinal.FunctionConfig;
import cn.finalteam.galleryfinal.GalleryFinal;
import cn.finalteam.galleryfinal.ImageLoader;
import cn.finalteam.galleryfinal.ThemeConfig;

/**
 * ====================== BaseApplication ========================
 * 基类  完成一些 初始化 配置操作
 * @author SGamble
 */
public class BaseApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        //========================== GalleryFinal - 图片选择 ==========================
        //初始化 ImageLoader
        com.nostra13.universalimageloader.core.ImageLoader imageLoader = com.nostra13.universalimageloader.core.ImageLoader.getInstance();
        imageLoader.init(ImageLoaderConfiguration.createDefault(this));
        //配置主题
        //ThemeConfig.CYAN
        ThemeConfig theme = new ThemeConfig.Builder()
        .build();
        //配置功能
        FunctionConfig functionConfig = new FunctionConfig.Builder()
                .setEnableCamera(true)
                .setEnableEdit(true)
                .setEnableCrop(true)
                .setEnableRotate(true)
                .setCropSquare(false)
                .setEnableRotate(true)
                .setEnablePreview(true)
        .build();
        //配置imageloader
        ImageLoader imageloader = new UILImageLoader();
        //设置核心配置信息
        CoreConfig coreConfig = new CoreConfig.Builder(this, imageloader, theme)
                .setDebug(BuildConfig.DEBUG)
                .setFunctionConfig(functionConfig)
        .build();
        GalleryFinal.init(coreConfig);
    }
}

3.清单文件

4.创建UILImageLoader.java

package com.qr.galleryfinaldemo;

import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.drawable.Drawable;

import com.nostra13.universalimageloader.core.DisplayImageOptions;
import com.nostra13.universalimageloader.core.ImageLoader;
import com.nostra13.universalimageloader.core.assist.ImageSize;
import com.nostra13.universalimageloader.core.imageaware.ImageViewAware;

import cn.finalteam.galleryfinal.widget.GFImageView;

/**
 * ====================== UILImageLoader ========================
 *
 * @author SGamble
 */
public class UILImageLoader implements cn.finalteam.galleryfinal.ImageLoader {

    private Bitmap.Config mImageConfig;

    public UILImageLoader() {
        this(Bitmap.Config.RGB_565);
    }

    public UILImageLoader(Bitmap.Config config) {
        this.mImageConfig = config;
    }

    @Override
    public void displayImage(Activity activity, String path, GFImageView imageView, Drawable defaultDrawable, int width, int height) {
        DisplayImageOptions options = new DisplayImageOptions.Builder()
                .cacheOnDisk(false)
                .cacheInMemory(false)
                .bitmapConfig(mImageConfig)
                .build();
        ImageSize imageSize = new ImageSize(width, height);
        ImageLoader.getInstance().displayImage("file://" + path, new ImageViewAware(imageView), options, imageSize, null, null);
    }

    @Override
    public void clearMemoryCache() {

    }
}

5.使用

package com.qr.galleryfinaldemo;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import java.util.List;
import cn.finalteam.galleryfinal.GalleryFinal;
import cn.finalteam.galleryfinal.model.PhotoInfo;

public class MainActivity extends AppCompatActivity {

    //图片选择器
    private final int REQUEST_CODE_GALLERY = 1001;
    private Button btnSelPic;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btnSelPic = (Button)findViewById(R.id.btnSelPic);
        btnSelPic.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                GalleryFinal.openGallerySingle(REQUEST_CODE_GALLERY, mOnHanlderResultCallback);
            }
        });
    }

    /**
     * 选取图片后的回调
     */
    private GalleryFinal.OnHanlderResultCallback mOnHanlderResultCallback = new GalleryFinal.OnHanlderResultCallback() {
        @Override
        public void onHanlderSuccess(int reqeustCode, List resultList) {
            if (resultList != null) {
                Log.e("onHanlderSuccess: ", resultList.get(0).getPhotoPath());
            }
        }

        @Override
        public void onHanlderFailure(int requestCode, String errorMsg) {
            Log.e("onHanlderSuccess: ", errorMsg);
        }
    };
}
