我做了一个 Activity 。因为我必须为 api 使用一个异步任务。所以在那个异步任务中，我的 url 将根据一些数字动态生成。我试过如下，但这不是正确的方法。谁能告诉我如何制作这个网址？
我的尝试是:

最佳答案
确保您是否使用像在循环之前初始化它那样的构建器帮助程序类。
也就是说，UriBuilder是您问题的完美解决方案，它是用于构建或操作 url 的辅助类。
下面是一个例子:
Uri.Builder builder = new Uri.Builder();
builder.scheme("http")
.authority("yehki.epagestore.in")
.appendPath("app_api")
.appendPath("order.php")
.appendQueryParameter("customer_id", customer_id)
.appendQueryParameter("address_id", address_id);
for (int i = 0; i < carts.length(); i++) {
builder.appendQueryParameter("products["+i+"][productName]", cartList.get(i).get((Const.TAG_PRODUCT_NAME)));
builder.appendQueryParameter("products["+i+"][productId]", cartList.get(i).get((Const.TAG_PRODUCT_ID)));
builder.appendQueryParameter("products["+i+"][quantity]", cartList.get(i).get((Const.TAG_QUANTITY)));
builder.appendQueryParameter("products["+i+"][unit]", cartList.get(i).get((Const.TAG_UNIT)));
builder.appendQueryParameter("products["+i+"][unitPrice]", cartList.get(i).get((Const.TAG_RETAIL_PRICE)));
}
String myUrl = builder.build().toString();
