添加依赖
1.
implementation 'com.facebook.fresco:fresco:0.14.1'
1
2.Application
public class MyApp extends Application {
@Override
public void onCreate() {
super.onCreate();
Fresco.initialize(this);
}
}
在AndroidManifest.xml里添加网络权限,并注册APP
3.MainActivity
public class MainActivity extends AppCompatActivity {
private SimpleDraweeView bigdraweeView,draweeView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
draweeView = findViewById(R.id.my_img);
Uri path = Uri.parse("http://f.expoon.com/sub/news/2016/01/19/371688_230x162_0.jpg");
draweeView.setImageURI(path);
//高斯模糊
bigdraweeView = findViewById(R.id.my_big_img);
showUrlBlur(bigdraweeView,"http://f.expoon.com/sub/news/2016/01/19/371688_230x162_0.jpg",10,10);
}
public static void showUrlBlur(SimpleDraweeView draweeView, String url, int iterations, int blurRadius) {
try {
Uri uri = Uri.parse(url);
ImageRequest request = ImageRequestBuilder.newBuilderWithSource(uri)
.setPostprocessor(new IterativeBoxBlurPostProcessor(iterations, blurRadius))
.build();
AbstractDraweeController controller = Fresco.newDraweeControllerBuilder()
.setOldController(draweeView.getController())
.setImageRequest(request)
.build();
draweeView.setController(controller);
} catch (Exception e) {
e.printStackTrace();
}
}
