我正在尝试在Picasso的背景下加载一个包含20个网址的数组。到目前为止,我有下一个代码:
Log.d("GAME", "Loading all images");
for (int i = gamePieces.length-1; i >= 0; i--) {
GamePiece p = gamePieces[i];
Log.d("GAME", "I will load " + p.getImage());
Picasso.with(context).load(p.getImage()).into(target);
}
//loading the first one
Picasso.with(context).load(piece.getImage()).into(target);
我的target
对象是下一个:
Target target = new Target() {
@Override
public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
Log.d("GAME", "Image loaded" + ++test);
gameImage.setImageBitmap(bitmap); //ImageView to show the images
}
@Override
public void onBitmapFailed(Drawable arg0) {}
@Override
public void onPrepareLoad(Drawable arg0) {}
};
我想预先加载图片,这样我就可以在用户点击按钮的任何时候在ImageView中逐个显示。
第一张图片的加载速度非常快(很酷)但是for循环中的其他图片永远不会加载。我怎样才能解决这个问题?我需要图像开始在for循环中加载。

我不得不使用:
Picasso.with(getActivity().getApplicationContext()).load(p.getImage()).fetch();

也许您可以尝试执行以下操作:
Picasso mPicasso = Picasso.with(context); //Single instance
//if you are indeed loading the first one this should be in top, before the iteration.
Picasso.with(context).load(piece.getImage()).into(target);
Log.d("GAME", "Loading all images");
for (int i = gamePieces.length-1; i >= 0; i--) {
GamePiece p = gamePieces[i];
Log.d("GAME", "I will load " + p.getImage());
mPicasso.load(p.getImage()).into(target);
}
