android - 如何在android中使用 picasso 库将背景图像设置为 Activity 布局

Question

我正在使用 picasso 库从服务器加载图像。我可以使用 Picasso 将背景图像设置为 ImageView。但我无法使用相同的设置背景图像。我也尝试了不同的方法来将图像设置为 Activity 布局背景。请帮助我。

我的代码如下:

 
Picasso.with(getApplicationContext()).load("<a href="https://cms-assets.tutsplus.com/uploads/users/21/posts/19431/featured_image/CodeFeature.jpg" rel="noreferrer noopener nofollow">https://cms-assets.tutsplus.com/uploads/users/21/posts/19431/featured_image/CodeFeature.jpg</a>").into(new Target() {<p></p>

        @Override
        public void onPrepareLoad(Drawable arg0) {
            // TODO Auto-generated method stub
            Toast.makeText(getApplicationContext(), "Start Loading", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onBitmapLoaded(Bitmap bitmap, LoadedFrom arg1) {
            // TODO Auto-generated method stub
            loginLayout.setBackground(new BitmapDrawable(getApplicationContext().getResources(), bitmap));
        }

        @Override
        public void onBitmapFailed(Drawable arg0) {
            // TODO Auto-generated method stub
            Toast.makeText(getApplicationContext(), "Failed Loading", Toast.LENGTH_SHORT).show();
        }
    });

Answer 1

尝试使用 setBackgroundDrawable 而不是 setBackground

@Override
    public void onBitmapLoaded(Bitmap bitmap, LoadedFrom arg1) {
        // TODO Auto-generated method stub
        loginLayout.setBackgroundDrawable(new BitmapDrawable(getApplicationContext().getResources(), bitmap));
    }
