在主活动或用于设置全局应用变量的单例类中定义两个新方法。您可能需要使用共享首选项来获取要比较的时间值。
public void pause(Activity act) {
// Record timeout time in case timeout service is killed
long time = System.currentTimeMillis();
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(act);
SharedPreferences.Editor edit = preferences.edit();
edit.putLong("Timeout_key", time);// start recording the current time as soon as app is asleep
edit.apply();
Timeout.start(act);
}
public void resume(Activity act) {
//Timeout.cancel(act);
// Check whether the timeout has expired
long cur_time = System.currentTimeMillis();
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(act);
long timeout_start = preferences.getLong("Timeout_key", -1);
// The timeout never started
if (timeout_start == -1) {
return;
}
//long sTimeout = preferences.getLong("idle_delay", 30000);
long timeout;
try {
//timeout = Long.parseLong(sTimeout);
timeout=idle_delay;
} catch (NumberFormatException e) {
timeout = DEFAULT_TIMEOUT;
}
// We are set to never timeout
if (timeout == -1) {
return;
}
if (idle){
long diff = cur_time - timeout_start;
if (diff >= timeout) {
//Toast.makeText(act, "We have timed out", Toast.LENGTH_LONG).show();
showLockDialog();
}
}
}
}
修改基本活动中的onPause（）和onResume（）方法
@Override
protected void onResume() {
super.onResume();
mApp.setCurrentActivity(this);
mApp.resume(this);
}
@Override
protected void onPause() {
super.onPause();
mApp.pause(this);
}
