我只希望将时间设置为10分钟。每当完成/完成10分钟时，我的按钮立即都将被禁用并弹出消息。我已经在按钮事件上启动了计时器，还在按钮事件上也停止了。但是我想开始新的活动开始并且所有按钮和textview禁用时的时间，这些空闲和自动结束时间为10分钟。并显示弹出消息。这该怎么做？
这是我的代码。

活动代码
public class TimerDemo extends Activity
{
private Button startButton;
private Button pauseButton;
private TextView timerValue;
private long startTime = 0L;
private Handler customHandler = new Handler();
long timeInMilliseconds = 0L;
long timeSwapBuff = 0L;
long updatedTime = 0L;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.demo_one);
timerValue = (TextView) findViewById(R.id.timerValue);
startButton = (Button) findViewById(R.id.startButton);
startButton.setOnClickListener(new View.OnClickListener()
{
public void onClick(View view)
{
startTime = SystemClock.uptimeMillis();
customHandler.postDelayed(updateTimerThread, 0);
}
});
pauseButton = (Button) findViewById(R.id.pauseButton);
pauseButton.setOnClickListener(new View.OnClickListener()
{
public void onClick(View view)
{
timeSwapBuff += timeInMilliseconds;
customHandler.removeCallbacks(updateTimerThread);
}
});
}
private Runnable updateTimerThread = new Runnable()
{
public void run()
{
timeInMilliseconds = SystemClock.uptimeMillis() - startTime;
updatedTime = timeSwapBuff + timeInMilliseconds;
int secs = (int) (updatedTime / 1000);
int mins = secs / 60;
secs = secs % 60;
int milliseconds = (int) (updatedTime % 1000);
timerValue.setText("" + mins + ":"
+ String.format("%02d", secs) + ":"
+ String.format("%03d", milliseconds));
customHandler.postDelayed(this, 0);
}
};
}
最佳答案
使用countdowntimer实现这一目标
new CountDownTimer(60**10*1000, 1000) {
public void onTick(long millisUntilFinished) {
time.setText("seconds remaining: "
+ millisUntilFinished / 1000);
}
public void onFinish() {
here you write the function to start
button to disable and popup
}
}.start();
