android 定时执行_android耗电怎么解决[通俗易懂]

CountDownTimer

new CountDownTimer(3000, 1000) {

public void onTick(long millisUntilFinished) {

if (mTicketSuccessBtn != null) {

mTicketSuccessBtn.setBackgroundColor(Color.parseColor(“#8f8f8f”));

mTicketSuccessBtn.setText(“手动出票(” + millisUntilFinished / 1000 + “)”);

}

}

public void onFinish() {

if (mTicketSuccessBtn != null) {

mTicketSuccessBtn.setBackgroundColor(Color.parseColor(“#3faff8”));

mTicketSuccessBtn.setEnabled(true);

}

}

}.start();

AlarmManager，Handler， Timer， Thread。

AlarmManager

AlarmManager是系统开放的闹钟功能，使用方式和普通的manager没有区别。

AlarmManager am = (AlarmManager)mContext.getSystemService(Context.ALARM_SERVICE); // Schedule the alarm! Intent intent = new Intent(XXXXX);
