我是Java和android studio整体的新手，并且想知道是否有任何方法可以嵌套2个随机函数。
我在XML文件中有字符串数组，并且每个字符串数组都在我的java文件中定义并添加到另一个数组中。
我一直在尝试从第一个数组中随机选择一个字符串数组，然后从所选的字符串数组中随机选择一个字符串项。我还坚持从字符串数组中获取此字符串项，以将其放置在预定义的TextView中。
下面是我的代码的摘要，如果可能的话，我希望在其中进行。
任何建议或想法都将不胜感激。
final String[][] planet = {Earth, Moon, Europa, etc...};
hint.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
int randomIndex1 = new Random().nextInt(planet.length);
String[] randomHint1 = planet[randomIndex1];
hint1.setText(randomIndex1);}
XML file for strings is below:
