Android - 毕加索只显示占位符，而不是来自 URL 的图像

Question

我有这个代码

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ImageView image_view = (ImageView)findViewById(R.id.imageView1);

        Picasso.with(getApplicationContext()).load("http://nuclearpixel.com/content/icons/2010-02-09_stellar_icons_from_space_from_2005/earth_128.png").placeholder(R.drawable.ic_launcher).noFade().into(image_view);
    }

我想在我的 imageview 中查看来自 url 的图像......但是，而不是仅占位符显示的图像。可能是什么问题？

尝试只使用 picasso.load() 而不是 Picasso.with()

类似这样的：

Picasso.Builder builder = new Picasso.Builder(getApplicationContext());
Picasso picasso = builder.build();
picasso.load("http://nuclearpixel.com/content/icons/2010-02-09_stellar_icons_from_space_from_2005/earth_128.png").placeholder(R.drawable.ic_launcher).noFade().into(image_view);
