我的问题就像这个问题在嵌套的RecyclerView中使用水平滚动滚动行为

就像Google Play商店一样,我在父级RecyclerView中有一个嵌套的RecyclerView(Horizo​​ntal).父级RecyclerView是CoordinatorLayout的子级,其中工具栏在父级RecyclerView滚动发生时展开和折叠.

在孩子的RecyclerView外面一切正常,向上滚动CollapsingToolbar会折叠,但是当我触摸其中一个子级RecyclerView并向上滚动时,父级RecyclerView会滚动并且CollapsingToolbar不起作用.

如果需要那么我将在这里添加我的源代码..

任何帮助将不胜感激!!

我试图将base64编码的字符串解码为android中的位图.编码的字符串将以"image/jpeg; base64"开头

我使用以下方法:

public static Bitmap decodeBase64(String input)
{
    byte[] decodedByte = Base64.decode(input, Base64.DEFAULT); 
    // also tried using Base64.URL_SAFE , Base64.NO_PADDING

    return BitmapFactory.decodeByteArray(decodedByte, 0, decodedByte.length);
}

假设我将上述方法称为

ImageView get_img=(ImageView)fundViewByID(R.id.getImg);  
get_img.setImageBitmap(ImageCache.decodeBase64(url))

当我运行代码时,它会抛出

--- SkImageDecoder :: Factory返回null

要么

错误的base-64与IllegalArgumentException

以下是base64字符串

我试过搜索,但找不到任何东西.我的问题是" 我如何警告2个或更多用户,如果他们在彼此附近？ "在Android中使用地理围栏或其他东西.

说,如果UserA在足球场,而UserB在足球场附近散步.然后UserA和UserB自动获得UserA/UserB在附近的通知.

我将从服务器yyyy-mm-dd hh:mm:ss收到的日期转换为dd-mm-yyyy hh:mm:ss am/pm

我写了下面的代码来做到这一点..

SimpleDateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss", Locale.getDefault());\nSimpleDateFormat outputFormat = new SimpleDateFormat("dd-MM-yyyy, hh:mm:ss a", Locale.getDefault());\n\n String out = "";\n inputFormat.setTimeZone(TimeZone.getTimeZone("UTC")); //Also tried GMT+00:00\n\n Date date = inputFormat.parse(str_date);\n\n outputFormat.setTimeZone(TimeZone.getDefault());\n out = outputFormat.format(date);\n\n L.c("The date format for " + str_date + " is " + out);\n\n return out;\n

一切正常，除非您注意到下面的控制台日志 06:21:48 am、06:09:44 am 以及少数其他人显示 AM 而不是 PM。

我的代码有错吗？或者有什么bug吗？
