按下按钮后，我正在尝试更改imageView。我希望图像以1秒的间隔改变。它应该不断改变图像60秒。我已经为它写了一个代码。但最终的更改仅在应用程序中显示。未显示所有其他59个更改。我是线程和计时器的新手。请帮我解决问题。

如果我关注你的问题，我认为你需要将你的监听器代码放在onCreate方法中。并在play方法中启动一个新线程。
public void play() {
play.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
new Thread(new Runnable(){
public void run(){
int timer = 0;
while (timer < 60) {
timer++;
Random random = new Random();
int guess = random.nextInt(9);
Log.d("guess", "" + guess);
final int[] selected = new int[1];
try {
Thread.sleep(1000);
timer++;
} catch (InterruptedException e) {
e.printStackTrace();
}
runOnUiThread(new Runnable(){
public void run() {
if (guess == 0) {
Log.d("thismycolor", "pink");
imageView.setImageResource(image[0]);
} else if (guess == 1) {
imageView.setImageResource(image[1]);
Log.d("thismycolor", "blue");
} else if (guess == 2) {
imageView.setImageResource(image[2]);
Log.d("thismycolor", "red");
} else if (guess == 3) {
imageView.setImageResource(image[3]);
Log.d("thismycolor", "orange");
} else if (guess == 4) {
imageView.setImageResource(image[4]);
Log.d("thismycolor", "green");
} else if (guess == 5) {
imageView.setImageResource(image[5]);
Log.d("thismycolor", "black");
} else if (guess == 6) {
imageView.setImageResource(image[6]);
Log.d("thismycolor", "brown");
} else if (guess == 7) {
imageView.setImageResource(image[7]);
Log.d("thismycolor", "yellow");
} else if (guess == 8) {
imageView.setImageResource(image[8]);
Log.d("thismycolor", "turquoise");
}
}
});
}
}).start();
}
});
}
还有一件事让你成像public static volatile ImageView imageView;
