我在我的应用程序中使用 Picasso。它工作正常，但花费太多时间将图像显示到 ImageView 中。任何人都可以告诉我原因是什么以及如何修复它吗？
我正在使用此代码:
Picasso.with(image.getContext())
.load(imageIds[currentIndex])
.transform(new BitmapTransform(MAX_WIDTH, MAX_HEIGHT))
.skipMemoryCache()
.resize(size, size)
.centerInside()
.into(image);
其中 MAX_WIDTH 和 MAX_HEIGHT 声明为:
private static final int MAX_WIDTH = 1000;
private static final int MAX_HEIGHT = 700;
代码是:
public class BitmapTransform implements Transformation {
int maxWidth;
int maxHeight;
public BitmapTransform(int maxWidth, int maxHeight) {
this.maxWidth = maxWidth;
this.maxHeight = maxHeight;
}
@Override
public Bitmap transform(Bitmap source) {
int targetWidth, targetHeight;
double aspectRatio;
if (source.getWidth() > source.getHeight()) {
targetWidth = maxWidth;
aspectRatio = (double) source.getHeight() / (double) source.getWidth();
targetHeight = (int) (targetWidth * aspectRatio);
} else {
targetHeight = maxHeight;
aspectRatio = (double) source.getWidth() / (double) source.getHeight();
targetWidth = (int) (targetHeight * aspectRatio);
}
Bitmap result = Bitmap.createScaledBitmap(source, targetWidth, targetHeight, false);
if (result != source) {
source.recycle();
}
return result;
}
@Override
public String key() {
return maxWidth + "x" + maxHeight;
}
};
添加setLoggingEnabled(true)后日志如下: 由于此处字数限制，无法显示完整日志。

最佳答案
好吧，我将逐行解释昂贵的操作:
.load(imageIds[currentIndex])
如上所述，这将从互联网或文件系统加载您的图像。在第一种情况下，下载时间取决于图像大小和互联网连接质量。在第二种情况下，它仅取决于图像大小，但请记住磁盘操作也是性能昂贵的。
.transform(new BitmapTransform(MAX_WIDTH, MAX_HEIGHT))
在这里，您正在对新位图应用转换，这需要分配额外的内存来创建缩放的位图。
.resize(size, size)
在这里，您再次调整图像大小 - 我不熟悉 picasso 的 resize 实现，但我相信它也需要额外的内存。实际上为什么要调整图像大小两次？也许您应该考虑如何在一个转换中组合两个调整大小操作。
其他内容对性能没有严重影响。
关于android - 为什么 Picasso 花时间在 ImageView 中显示图像？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/25255597/
