I want to display data to Android Application the data is coming from Esp32 module to Android Application but I can't split this array its seems it string and when I get the index value 9 ..its gave me array array index out of bound 我从 Docklight 应用程序发送此数据
***我想拆分此数据，但它显示数组索引超出范围，请帮助我，这是我的第一个工作项目，我想尽快完成此任务。
//这是我的Android应用程序的java代码
public void onCharacteristicChanged（最终字节[]数据）{
runOnUiThread(new Runnable() {
@Override
public void run() {
String ipData = HexUtil.formatHexString(data);
Log.d(Tag+"OP",ipData);
if (ipData!=null) {
String [] data=ipData.split("/");
builderList.clear();
convertHaxToASCII(data);
setButtonText();
setText();
alarms.checkAlert(builderList.get(9).toString(), DetailBLE.this);
}
if (!builderList.isEmpty())
{
setTitle(builderList.get(1).toString());
setArrowsStatus();
setBatteryImage();
}
}
});
}
**我要分割这个数据data = ups/123/334/233/244/24/24/545/56/343/54634/454/End 以数组的形式，然后我通过索引在用户屏幕上显示它 ** 就像 ups --get(0)
就像电源一样--get(1) 就像太阳能--get(2) 就像非太阳能--get(3) 就像电池电量低--get(4) 就像放电电流--get(5)
