我正在使用Google Places API检索有关地点的数据,但无法找到如何获取该地点的图片,Google Places API只提供不一样的图标.例如,我需要您在网络浏览器中搜索Google地图中的地点时获得的照片.通常会有更多来自Panoramio的图片,但Panoramio API只能按位置搜索图片,而不能按特定的餐馆或酒店名称搜索.有任何想法吗？

我正在按照这个例子来创建我的应用程序现在我正在尝试在我的工具栏中添加图像但是图像没有显示,我正在尝试设置我的应用程序徽标,以下是我的代码和工具栏xml可以任何人告诉我什么是错误？

我正在为Marshmallow设备实现运行时权限请求.我已经设置了我的构建并编译sdk为API 23.仍然Manifest.permission.READ_PHONE_STATE无法识别

我导入了我的项目Android Studio 1.3.2,现在显示错误

我正在使用Android-Universal-Image-LoaderHTTPS在我的Android应用程序上从远程服务器加载图像.要访问映像,客户端应提供有效的令牌,有时服务器可能会返回"过期的crsf令牌"错误.为了处理此行为,应定义自定义ImageDownloader.下面是我的实现中应该覆盖的方法的基本实现.

protected InputStream getStreamFromNetwork(String imageUri, Object extra) throws IOException {
    HttpURLConnection conn = createConnection(imageUri, extra);

    int redirectCount = 0;
    while (conn.getResponseCode() / 100 == 3 && redirectCount < MAX_REDIRECT_COUNT) {
         conn = createConnection(conn.getHeaderField("Location"), extra);
         redirectCount++;
    }

    InputStream imageStream;
    try {
         imageStream = conn.getInputStream();
    } catch (IOException e) {
         // Read all data to allow reuse connection (http://bit.ly/1ad35PY)
         IoUtils.readAndCloseStream(conn.getErrorStream());
         throw e;
    }
    if (!shouldBeProcessed(conn)) {

我想添加一些点击动画如下所示我回收的看法,但没有成功.这是我的一些代码.

在我的活动中

@Override
protected void onCreate(Bundle savedInstanceState) {
    ...
    mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view);
    ItemOffsetDecoration itemDecoration = new ItemOffsetDecoration(this, R.dimen.card_item_offset);
    mRecyclerView.addItemDecoration(itemDecoration);

    mLayoutManager = new LinearLayoutManager(this);
    mRecyclerView.setLayoutManager(mLayoutManager);

    mAdapter = new CustomAdapter(this);
    mRecyclerView.setAdapter(mAdapter);
}

在我的ViewHolder中

public CustomViewHolder(View itemView) {
    super(itemView);
    this.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            /* on click stuff here */
        }
    });
}

在我的CardView.xml里面

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView

不确定问题出在哪里,但提前感谢您帮助=)

我的firebase项目有问题.我按照firebaseGitHub文档中的步骤进行操作,但是我得到了这个例外

java.lang.RuntimeException: java.lang.NoSuchMethodException: <init>
[class android.view.View]

这是一个ViewHolder不是内部阶级的类.

public class ProductViewHolder extends RecyclerView.ViewHolder{
public View mView;
public ImageView img;
public TextView title;
public TextView price;
public RatingBar stars;


ProductViewHolder(View itemView) {
    super(itemView);

    mView = itemView;
    img = (ImageView) itemView.findViewById(R.id.productImg);
    title = (TextView) itemView.findViewById(R.id.txtTitle);
    price = (TextView) itemView.findViewById(R.id.txtPrice);
    stars = (RatingBar) itemView.findViewById(R.id.ratingBar);
    }
}

这是与firebase相关的代码

@Override
protected void onStart() {
    super.onStart();

    // Recycler adapter
    FirebaseRecyclerAdapter<Product, ProductViewHolder> adapter =
            new FirebaseRecyclerAdapter<Product, ProductViewHolder>(
                    Product.class,
                    R.layout.product_list_item,
                    ProductViewHolder.class,
