我可以将Picasso的图片加载到操作栏上吗? [英] Can I load a picture with Picasso to the action bar?

问题描述

我一直在广泛使用 Picasso 来通过Internet将图像检索到我的应用程序.现在，我遇到了一种情况，我需要在操作栏中检索一个小图像(例如标题文本旁边的徽标).

I've been using Picasso extensively to retrieve images over the internet to my app. Now, I've run into a situation where I need to retrieve a small image to the action bar (like a logo next to the title text).

是否可以用毕加索做到这一点?如果是这样，我该怎么办?

Is it possible to do this with Picasso? If so, how would I do that?

推荐答案

我找到了一个使用Picasso的Target类并且不需要自定义操作栏的解决方案.

I found out a solution which uses Picasso's Target class and does not require a custom Action Bar.

final ActionBar ab = getSupportActionBar();
Picasso.with(this)
       .load(imageURL)
       .into(new Target()
       {
           @Override
           public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from)
           {
               Drawable d = new BitmapDrawable(getResources(), bitmap);
               ab.setIcon(d);
               ab.setDisplayShowHomeEnabled(true);
               ab.setDisplayHomeAsUpEnabled(true);
           }

           @Override
           public void onBitmapFailed(Drawable errorDrawable)
           {
           }

           @Override
           public void onPrepareLoad(Drawable placeHolderDrawable)
           {
           }
       });
