Question

案例：我在app上工作，根据Foursquare API的坐标检索有关本地场地的信息。所有信息都存储在数据库中，包括存储为前缀和链接后缀的场地特色照片。对于列表表示，我使用了recyclerview。我记录了url链接，看起来工作正常。这是我的onBindViewHolder方法：

public void onBindViewHolder(ViewHolder holder, int position) {
    if (holder instanceof ItemViewHolder) {
        Venue venue = venueList.get(position);
        String url = venue.getFeaturedPhotos().getItems().get(0).getPrefix() + "120x120" + venue.getFeaturedPhotos().getItems().get(0).getSuffix();
        ((ItemViewHolder) holder).venueName.setText(venue.getName());
        ((ItemViewHolder) holder).streetAdr.setText(venue.getLocation().getAddress());
        ((ItemViewHolder) holder).rating.setText(venue.getRating().toString());
        Context context = ((ItemViewHolder) holder).venuePhoto.getContext();
        Picasso.with(context).load(url).into(((ItemViewHolder) holder).venuePhoto);;
        ((ItemViewHolder) holder).venue = venue;
    } else {
        ((ProgressViewHolder) holder).progressBar.setIndeterminate(true);

    }
}

这是我的项目的样子：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal">

    <ImageView
        android:id="@+id/venuePhoto"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:contentDescription="@string/imgDescr"
         />

    <TextView
        android:id="@+id/rating"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:text="@string/ratingSample"
        android:textSize="45sp" />

    <TextView
        android:id="@+id/venueName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_toLeftOf="@id/rating"
        android:layout_toRightOf="@id/venuePhoto"
        android:text="@string/VenueNameSample"
        android:textSize="20sp" />

    <TextView
        android:id="@+id/streetAdr"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/venueName"
        android:layout_toLeftOf="@id/rating"
        android:layout_toRightOf="@id/venuePhoto"

        android:text="@string/addressSample"
        android:textSize="20sp" />


</RelativeLayout>

Answer 1

我通过添加uri解析

找到了解决方案

String url = venue.getFeaturedPhotos().getItems().get(0).getPrefix() + "120x120" + venue.getFeaturedPhotos().getItems().get(0).getSuffix();
Uri uri = Uri.parse(url);

Android：Picasso不起作用
