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);

还在清单

中添加了必需的权限

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

修改

Logcat输出

Could not find method java.nio.file.Files.newOutputStream, referenced from method okio.Okio.sink
VFY: unable to resolve static method 19774: Ljava/nio/file/Files;.newOutputStream (Ljava/nio/file/Path;[Ljava/nio/file/OpenOption;)Ljava/io/OutputStream;

清单条目不正确。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，可能会出现连接问题 - 可能是防火墙或代理损坏。

您可以在毕加索通过创建Picasso.Builder并设置listener来检索图片时记录错误。

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);

使用该代码运行，您应该在logcat中看到连接错误。

无法使用Picasso加载图像
