毕加索第一次不调用onBitmapLoaded

Question

毕加索第一次不打onBitmapLoaded，如果您知道，请告诉我

        txtView = (TextView) centerRelative.getChildAt(i);
                Picasso.with(getBaseContext()).load(file[i-4]).into(new Target() {
                    @Override
                    public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                        txtView.setBackground(new BitmapDrawable(getResources(),bitmap));
//                      Not executing for the first time

                    }

                    @Override
                    public void onBitmapFailed(Drawable errorDrawable) {

                    }

                    @Override
                    public void onPrepareLoad(Drawable placeHolderDrawable) {
//                      executing for the first time
                    }
                });

Target target = new Target() {
                    @Override
                    public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                        txtView.setBackground(new BitmapDrawable(getResources(),bitmap));
                        logd("onBitmapLoaded");
                    }

                    @Override
                    public void onBitmapFailed(Drawable errorDrawable) {

                    }

                    @Override
                    public void onPrepareLoad(Drawable placeHolderDrawable) {

                    }
                };
                Picasso.with(getBaseContext()).load(file[i-4]).into(target);

解决方案：您必须在此处进行一些更改：

代替写作：

new Target() {...}

在您的into(..)内，您必须创建一个Target类的全局对象。不要将其设为本地对象，因为它可能会被垃圾回收。所以，

第1步：

制作全局对象：

Target target = new Target() {
    @Override
    public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
        ....
    }
    @Override
    public void onBitmapFailed(Drawable errorDrawable) {
        ....
    }
    @Override
    public void onPrepareLoad(Drawable placeHolderDrawable) {
        ....
    }
};

最后，在您的into(...)中使用该目标：

Picasso.with(getBaseContext()).load(file[i-4]).into(target);

尝试一下，希望对您有所帮助。
