Here I have used below code:
在这里我使用了以下代码：
String[] stockArrVideo = new String[Appscontent.Sub_arraylistvideo.size()];
stockArrVideo = Appscontent.Sub_arraylistvideo.toArray(stockArrVideo);
for (String s : stockArrVideo) {
if (s.startsWith(number)) {
String _Substring;
_Substring = s.substring(1);
if(_Substring.equals("")||_Substring == null) {
_Substring = "No Records";
}
Appscontent.Sub_arraylistvideosub.add(_Substring);
}
h++;
}
If the data is empty, it means I have to display the "No Records" message. Otherwise display the correct data.
如果数据为空，则意味着我必须显示“无记录”消息。否则显示正确的数据。
TextView mVideo = new TextView(this);
System.out.println(Appscontent.Sub_arraylistvideosub.get(j));
mVideo.setText(Appscontent.Sub_arraylistvideosub.get(j));
mVideo.setLayoutParams(textLayoutParams);
mVideo.setBackgroundColor(Color.BLACK);
Here I have wrote the code for checking the empty data.
这里我写了检查空数据的代码。
What is causing this exception?
是什么导致了这个异常？

IndexOutOfBoundsException: Invalid index 1, size is 1
how can i resolve these error ???
我该如何解决这些错误？？？
You need to check the size of your array, the problem seems to happen with: Appscontent.Sub_arraylistvideosub.get(j)Simply check if your index is valid before trying to use it, like:
您需要检查数组的大小，问题似乎发生在：Appscontent.Sub_arraylistvideosub.get(j)在尝试使用索引之前，只需检查它是否有效，例如：
if(j < Appscontent.Sub_arraylistvideosub.length)
System.out.println(Appscontent.Sub_arraylistvideosub.get(j));
