Android 自定义数字键盘（二）随机数字

private List<Character> keylabels= Arrays.asList('0','1','2','3','4','5','6','7','8','9');

public  void setRandomKeyBoard(boolean isRandom){
if (isRandom){
Keyboard keyboard=getKeyboard();
List<Keyboard.Key> keys=keyboard.getKeys();
Collections.shuffle(keylabels);
int i=0;
for (Keyboard.Key key:keys){
if(key.codes[0]!=KEYCODE_EMPTY&&key.codes[0]!=Keyboard.KEYCODE_DELETE){
key.label=keylabels.get(i).toString();
//自己定义code码需要跟之前布局里面的不同，如果不修改code码，对应的还是之前的label值
//可以自己试一下
key.codes[0]=keylabels.get(i);
i++;
}
}
setKeyboard(keyboard);
}
