简单网络图片加载

1、依赖里面加入

compile ‘com.github.bumptech.glide:glide:3.6.1‘2、布局里面放置一个ImageView控件

<ImageView    android:id="@+id/img"    android:layout_width="match_parent"    android:layout_height="match_parent"/>

3、代码里面

protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_img_test);

ImageView img = (ImageView) findViewById(R.id.img);//layout中放一个ImageView控件，id是@+id/img

String url = "https://ss0.bdstatic.com/70cFuHSh_Q1YnxGkpoWK1HF6hhy/it/u=3917297328,2353437284&fm=27&gp=0.jpg";

Glide.with(this).load(url).placeholder(R.drawable.myimg).crossFade().into(img);}
