android - java中的switch case语句中，case所对应的数目是不确定的，能否动态改变case 的个数？
现在方法中传入的menuList的数目是不确定的，每个menuList.get(i),都对应一个runnableList.get(i)。现在需要根据menuList.size()动态改变case的数目，求思路
public boolean Confim(final Activity act, String title, final String[] menuList, final List<Runnable> runList) {
runnableList = runList;
AlertDialog.Builder builder = new AlertDialog.Builder(act);
builder.setTitle(title);
builder.setItems(menuList, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int which) {
switch (which) {
case 0:
if (runnableList.get(0) == null) return;
runnableList.get(0).run();
break;
case 1:
if (runnableList.get(1) == null) return;
runnableList.get(1).run();
break;
case 2:
if (runnableList.get(2) == null) return;
runnableList.get(2).run();
break;
}
}
});
builder.show();
return false;
}
