先加入依赖:
implementation 'com.facebook.fresco:fresco:1.9.0'
implementation 'com.facebook.fresco:animated-gif:1.9.0'
implementation 'com.facebook.fresco:animated-webp:1.9.0'
implementation 'com.facebook.fresco:webpsupport:1.9.0'初始化 fresco:
public class MyApp extends Application {
@Override
public void onCreate() {
super.onCreate ( );
Fresco.initialize ( this );
}
}
Manifest 里配置:
android:name=".MyApp"
在main里进行加载获取图片:
//只是显示图片

android:name=".MyApp"在布局里写上控件

当然了,除此之外还有很多的用法:
在写控件的时候,可以直接对其进行操作的属性:
fresco:fadeDuration="300" // 淡入淡出的持续时间
fresco:actualImageScaleType="focusCrop" // 实际图像的缩放类型
fresco:placeholderImage="@color/wait_color" //占位图
fresco:placeholderImageScaleType="fitCenter" //占位图的缩放类型
fresco:failureImage="@drawable/error" //下载失败显示的图片
fresco:failureImageScaleType="centerInside" //失败图的缩放类型
fresco:retryImage="@drawable/retrying"
//图片加载失败时显示，提示用户点击重新加载，重复加载4次还是没有加载出来的时候才会显示failureImage的图片
fresco:retryImageScaleType="centerCrop" //重新加载的图片缩放类型
fresco:progressBarImage="@drawable/progress_bar" //进度条图片
fresco:progressBarImageScaleType="centerInside"
fresco:progressBarAutoRotateInterval="1000"
//进度图自动旋转间隔时间(单位：毫秒ms)
fresco:backgroundImage="@color/blue"
//背景图片，这里的背景图片首先被绘制
fresco:overlayImage="@drawable/watermark"
// 设置叠加图，在xml中只能设置一张叠加图片，如果需要多张图片的话，需要在java代码中设置哦
fresco:pressedStateOverlayImage="@color/red"
// 设置点击状态下的叠加图
fresco:roundAsCircle="false" //设置为圆形图
fresco:roundedCornerRadius="1dp" // 圆角半径
fresco:roundTopLeft="true" // 左上角是否为圆角
fresco:roundTopRight="false"
fresco:roundBottomLeft="false"
fresco:roundBottomRight="true"
fresco:roundWithOverlayColor="@color/corner_color"
fresco:roundingBorderWidth="2dp" //边框的宽度
fresco:roundingBorderColor="@color/border_color" //边框颜色
