未加载壁画中的图像

李永寿
2023-03-14

我试图在壁画中加载图像，但图像似乎没有加载。当我添加一个占位符视图时，会显示占位符。

public static void loadImg(final Context c, final SimpleDraweeView view, final String img){
    Uri uri = Uri.parse("https://placekitten.com/g/201/300");
    view.setImageURI(uri);
}

注意，我正在应用程序中初始化Fresco，我在清单中确实有internet使用情况。

        <com.facebook.drawee.view.SimpleDraweeView
        android:id="@+id/small_box_image"
        android:layout_width="match_parent"
        android:layout_height="150dp"
        fresco:placeholderImage="@drawable/google"
        fresco:fadeDuration="300"
        fresco:viewAspectRatio="1.33"
        />

public static View generateTileView(Context c, Tile t){

    LayoutInflater inflater = (LayoutInflater) c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View view;
    boolean desc = false;

    switch(t.getObjectTypeName()){
        case Tile.OBJECT_NAME:
            view = inflater.inflate(R.layout.view_tile_small_object, null);
            break;
        case Tile.LOOK_CLOSER_NAME:
            view = inflater.inflate(R.layout.view_tile_small_look_closer, null);
            desc = true;
            break;
        case Tile.STORY_NAME:
            view = inflater.inflate(R.layout.view_tile_small_story, null);
            desc = true;
            break;
        case Tile.TOUR_NAME:
            view = inflater.inflate(R.layout.view_tile_small_tour, null);
            desc = true;
            break;
        default:
            view = inflater.inflate(R.layout.view_tile_small_object, null);
            break;
    }

    TextView type = (TextView) view.findViewById(R.id.small_box_type);
    TextView title = (TextView) view.findViewById(R.id.small_box_title);
    SimpleDraweeView img = (SimpleDraweeView) view.findViewById(R.id.small_box_image);

    if(desc) {
        TextView descText = (TextView) view.findViewById(R.id.small_box_desc);
        if ( t.getDescription() != null) {
            descText.setText(t.getDescription());
            descText.setTypeface(TypefaceUtil.get(c, TypefaceUtil.ENZO_M));
        }else{
            descText.setVisibility(View.GONE);
        }
    }

    title.setText(t.getTitle());
    title.setTypeface(TypefaceUtil.get(c, TypefaceUtil.SOFIA_BOLD));
    type.setText(t.getObjectTypeName());
    type.setTypeface(TypefaceUtil.get(c, TypefaceUtil.SOFIA_BOLD));
    ViewUtils.loadImg(c, img, t.getImg());

    return view;
}

试试这个

SimpleDraweeView imageView= (SimpleDraweeView) v.findViewById(R.id.full_ad_unit);

Uri imageUri = Uri.parse(imagePath);

ImageRequest request = ImageRequest.fromUri(imageUri);

DraweeController controller = Fresco.newDraweeControllerBuilder()
    .setImageRequest(request)
    .setOldController(imageView.getController()).build();

Log.e(TAG, "ImagePath uri " + imageUri);

imageView.setController(controller);
