问题描述
public void onClick(View v) {
// TODO Auto-generated method stub
switch(v.getId()){
case R.id.rollDice:
Random ranNum = new Random();
int number = ranNum.nextInt(6) + 1;
diceNum.setText(""+number);
sum = sum + number;
for(i=0;i<8;i++){
for(j=0;j<8;j++){
int value =(Integer)buttons[i][j].getTag();
if(value==sum){
inew=i;
jnew=j;
buttons[inew][jnew].setBackgroundColor(Color.BLACK);
//I want to insert a delay here
buttons[inew][jnew].setBackgroundColor(Color.WHITE);
break;
}

break;

我想设置改变背景的命令之间的延迟。我试图用一个线程定时器和使用运行和捕捉尝试。但它不工作。我想这
I want to set a delay between the command between changing background. I tried using a thread timer and tried using run and catch. But it isn't working. I tried this
Thread timer = new Thread() {
public void run(){
try {
buttons[inew][jnew].setBackgroundColor(Color.BLACK);
sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
};
timer.start();
buttons[inew][jnew].setBackgroundColor(Color.WHITE);
但它才刚刚变为黑色。
But it is only getting changed to black.
推荐答案
试试这个code:
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
// Do something after 5s = 5000ms
buttons[inew][jnew].setBackgroundColor(Color.BLACK);
}
}, 5000);
