Fresco的簡單使用

1.導入依賴:implementation ‘com.facebook.fresco:fresco:0.12.0’

2.創建一個類繼承Application

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

3.在xml佈局文件中, 加入SimpleDraweeView控件:

<com.facebook.drawee.view.SimpleDraweeView
    android:id="@+id/my_image_view"
    android:layout_width="130dp"
    android:layout_height="130dp"
    fresco:placeholderImage="@drawable/my_drawable"
  />

4.在代碼中開始加載圖片:

Uri uri = Uri.parse("https://raw.githubusercontent.com/facebook/fresco/gh-pages/static/logo.png");
SimpleDraweeView draweeView = (SimpleDraweeView) findViewById(R.id.my_image_view);
draweeView.setImageURI(uri);

5.加載圓形圖片

RoundingParams roundingParams = RoundingParams.fromCornersRadius(5f);
roundingParams.setBorder(R.color.red, 1.0);
roundingParams.setRoundAsCircle(true);
draweeView.getHierarchy().setRoundingParams(roundingParams);
