android - 无法使用 picasso 加载图像

Question

我的代码:

  Picasso picasso = Picasso.with(getActivity());
  picasso.load("http://static1.gamespot.com/uploads/original/1550/15507091/2867734-7512874458-CAK00.jpg")
         .error(R.drawable.error)
         .placeholder(R.drawable.placeholder)
         .into(imageView);

还在 list 中添加了所需的权限

<uses-permission android:name="ANDROID.PERMISSION.INTERNET" />
<uses-permission android:name="ANDROID.PERMISSION.WRITE_EXTERNAL_STORAGE" />

编辑:

Logcat 输出

Could not find method java.nio.file.Files.newOutputStream, referenced from method okio.Okio.sink

Answer 1

list 条目不正确。它们区分大小写。试试这些:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

如果这不能解决问题，则可能存在连接问题 - 可能是防火墙或损坏的代理。

通过创建 Picasso.Builder 并设置 listener，您可以在 Picasso 检索图像时记录错误。

Picasso.Builder builder = new Picasso.Builder(getApplicationContext());
builder.listener(new Picasso.Listener() {
    @Override
    public void onImageLoadFailed(Picasso arg0, String arg1) {
        Log.e("Picasso Error", "Failed to load image: " + arg1);
    }
});
Picasso pic = builder.build();
pic.load("http://static1.gamespot.com/uploads/original/1550/15507091/2867734-7512874458-CAK00.jpg")
     .error(R.drawable.error)
     .placeholder(R.drawable.placeholder)
     .into(imageView);

运行该代码，您应该会在 logcat 中看到连接错误。
