我正在尝试向我的应用添加功能，该功能会使设备每隔一段时间进入睡眠状态。
目前，我正在使用android.permission.WRITE_SETTINGS，但是将来，我将使用android.permission.WRITE_SECURE_SETTINGS。
代码：
startWakeLockTest(); -->
dimScreenWithInterval(DIM_SCREEN_MID_LEVEL, TIMER_DIM_SCREEN_MID_LEVEL);
private void dimScreenWithInterval(final int screenBrightnessValue, final long handlerTime) {
mDimHandler = new Handler();
mDimRunnable = new Runnable() {
@Override
public void run() {
dimScreen(screenBrightnessValue);
if (handlerTime == TIMER_DIM_SCREEN_MID_LEVEL) {
dimScreenWithInterval(DIM_SCREEN_LOW_LEVEL, TIMER_DIM_SCREEN_LOW_LEVEL);
} else if (handlerTime == TIMER_DIM_SCREEN_LOW_LEVEL) {
putDeviceIntoSleepingMode();
}
}
};
mDimHandler.postDelayed(mDimRunnable, handlerTime);
}
private void putDeviceIntoSleepingMode() {
turnScreenOff();
}
private void turnScreenOff() {
mWakeLock = mPowerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "sensorsTest:tag");
mWakeLock.acquire(WAKE_LOG_TIMEOUT);
// because there is no easy way to put the device into sleep mode - just change the screen_off_timeout in settings and then chan=nge it back after on resume
Settings.System.putInt(getContentResolver(), Settings.System.SCREEN_OFF_TIMEOUT, 100);
}
基本上，我将系统screen_off_timer更改为0，然后在屏幕重新打开时将其设置回真实设备screen_off_time。
这样做似乎很奇怪也很糟糕……
有人有更好的解决方案吗？ 预先感谢
