框架学习系列一（图片加载框架）

图片加载框架

整理常用的图片加载框架

• Glide
• Fresco
• Volley
• Picasso
• Universal Image Loader

1. Glide接入使用

gradle配置

dependencies {
    //glide 图片加载
    compile 'com.github.bumptech.glide:glide:3.7.0'
}

ImageView im=(ImageView) findViewById(R.id.iv_image1);
Glide.with(this).load("http://img05.tooopen.com/images/20150531/tooopen_sy_127457023651.jpg").into(im);

2. Fresco接入使用

gradle配置

//fresco图片加载
compile 'com.facebook.fresco:fresco:1.3.0'

自定义 Application

public class MyApplication extends Application{
            @Override
            public void onCreate() {
                super.onCreate();
                //
                Fresco.initialize(this);
    }

布局文件xml添加

 添加：xmlns:fresco="http://schemas.android.com/apk/res-auto"

添加：com.facebook.drawee.view.SimpleDraweeView

代码调用

//需要指定宽高，要不图片加载不出来
Uri uri = Uri.parse("http://img05.tooopen.com/images/20150531/tooopen_sy_127457023651.jpg");
SimpleDraweeView draweeView = (SimpleDraweeView) findViewById(R.id.iv_fresco);
draweeView.setImageURI(uri);

3. Volley接入使用

gradle配置

//volley 官方clone工程，volley官方不在提供支持
compile 'com.mcxiaoke.volley:library:1.0.19'

代码调用

final ImageView im=(ImageView) findViewById(R.id.iv_volley);
 ImageRequest imageRequest = new ImageRequest(
         "http://img05.tooopen.com/images/20150531/tooopen_sy_127457023651.jpg",
         new Response.Listener() {
             @Override
             public void onResponse(Bitmap response) {
                 im.setImageBitmap(response);
             }
         }, 0, 0, Bitmap.Config.RGB_565, new Response.ErrorListener() {
     @Override
     public void onErrorResponse(VolleyError error) {
         im.setImageResource(R.mipmap.ic_launcher);
     }
 });

//volley 官方clone工程，volley官方不在提供支持
compile 'com.mcxiaoke.volley:library:1.0.19'

4. picasso接入使用

gradle配置

//picasso图片加载
compile 'com.squareup.picasso:picasso:2.5.2'

代码调用

ImageView im=(ImageView) findViewById(R.id.iv_picasso_image);
Picasso.with(getApplicationContext()).
load("http://img05.tooopen.com/images/20150531/tooopen_sy_127457023651.jpg").into(im);

5. Universal Image Loader接入使用

gradle配置

//Android-Universal-Image-Loader
compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'

自定义 Application

public class MyApplication extends Application{
            @Override
            public void onCreate() {
                super.onCreate();
                //ImageLoader
ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(this)
    .build();
ImageLoader.getInstance().init(config);

    }

代码调用

ImageView im=(ImageView) findViewById(R.id.iv_image_load);
ImageLoader imageLoader = ImageLoader.getInstance();
imageLoader.displayImage("http://img05.tooopen.com/images/20150531/tooopen_sy_127457023651.jpg", im);
imageLoader.loadImage("http://img05.tooopen.com/images/20150531/tooopen_sy_127457023651.jpg", new SimpleImageLoadingListener() {
    @Override
    public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
        Toast.makeText(ImageLoadActivity.this, ""+imageUri, Toast.LENGTH_SHORT).show();
        // Do whatever you want with Bitmap
    }
});
