Question

Picasso通常使用Android（API＆gt; 20）加载图片，但问题在于API＆lt; 20（无法从URL加载图像）。这是我的代码：

Java代码：

Picasso.with(getActivity()).setLoggingEnabled(true);
Picasso.with(getActivity()).load("https://apod.nasa.gov/apod/image/1701/M78_Tiziano_960.jpg").error(R.drawable.error_logo).memoryPolicy(MemoryPolicy.NO_CACHE).networkPolicy(NetworkPolicy.NO_CACHE).fit().into(img);
StatsSnapshot picassoStats = Picasso.with(getActivity()).getSnapshot();
Log.d("Picasso Stats", picassoStats.toString());

XML代码：

<ImageView
    android:id="@+id/testImg"
    android:layout_width="match_parent"
    android:layout_height="300dp"
    android:adjustViewBounds="true"
    android:scaleType="fitXY"
    android:layout_gravity="center"
    android:contentDescription="@string/apod_img"
    />

logcat的：

D/Picasso: Main        created      [R0] Request{https://apod.nasa.gov/apod/image/1701/M78_Tiziano_960.jpg resize(1080,900)}

Answer 1

尝试添加：

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

就在

之前

<Application

我想你的getView（）

中有以下几行代码

View rowView = mInflater.inflate(..., ..., ...);

ImageView img = (ImageView) rowView.findViewById(R.id.testImg);

前

Picasso.with(getActivity()).load("https://apod.nasa.gov/apod/image/1701/M78_Tiziano_960.jpg").error(R.drawable.error_logo).memoryPolicy(MemoryPolicy.NO_CACHE).networkPolicy(NetworkPolicy.NO_CACHE).fit().into(img);

无法使用Picasso 2.5.2从Android设备（API＆lt; 20）中的某些网址加载图片
