android - 如何在android中添加占位符图像

Question

这是我尝试实现占位符图像的示例代码。我从互联网上获取数据

@Override
protected void onPostExecute(Bitmap result) {
        if((imageview!=null)&&(result!=null)){
            ImageView imgview=imageview.get();
             if(imgview!=null){
                 imgview.setImageBitmap(result);
             }
            else{
                 Drawable place=imgview.getContext().getResources().getDrawable(R.drawable.ic_place);
                 imgview.setImageDrawable(place);
             }

        }
}

看看这个库: https://github.com/square/picasso

Picasso.with(context)
    .load(url)
    .placeholder(R.drawable.user_placeholder)
    .error(R.drawable.user_placeholder_error)
    .into(imageView);
