对我来说，这些方法不起作用。所以我使用其他场景(不是微不足道)来关闭我的屏幕。

Android有2个标志，负责清醒：

显示 - >屏幕TimeOut

应用程序 - >开发 - > 充电时保持清醒复选框。

我使用了以下流程：

首先保存您之前的配置，例如屏幕超时为1分钟，并 在充电时保持清醒状态。

之后，我取消选中充电时保持清醒并将屏幕超时设置为最短时间。

我注册广播接收器服务从屏幕关闭的Android获取事件。

当我关闭屏幕上的事件时，我将先前的配置设置为默认值：屏幕超时为1分钟并且 在检查充电时保持清醒状态。

取消注册接收器

15秒后 设备睡觉

这是代码片段：

广播接收器

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

/**

* Catch Screen On/Off

* */

public class BroadcastReceiverScreenListener extends BroadcastReceiver{

private BroadCastListenerCallBackItf mBroadCastListenerCallBack = null;

public BroadcastReceiverScreenListener(

BroadCastListenerCallBackItf broadCastListenerCallBack) {

this.mBroadCastListenerCallBack = broadCastListenerCallBack;

}

@Override

public void onReceive(Context arg0, Intent intent) {

if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {

mBroadCastListenerCallBack.broadCastListenerCallBack__ScreenOff_onResponse();

}

}

}

用作回调的接口

public interface BroadCastListenerCallBackItf {

public void broadCastListenerCallBack__ScreenOff_onResponse();

}

主类2种方法：

....

AndroidSynchronize mSync = new AndroidSynchronize();

....

public void turnScreenOff(int wait){

IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);

filter.addAction(Intent.ACTION_SCREEN_OFF);

BroadCastListenerCallBackItf broadCastListenerCallBack = this;

BroadcastReceiver mReceiver = new BroadcastReceiverScreenListener(broadCastListenerCallBack);

m_context.registerReceiver(mReceiver, filter);

//set Development --> disable STAY_ON_WHILE_PLUGGED_IN

Settings.System.putInt(

m_context.getContentResolver(),

Settings.System.STAY_ON_WHILE_PLUGGED_IN,

0                                );

// take current screen off time

int defTimeOut = Settings.System.getInt(m_context.getContentResolver(),

Settings.System.SCREEN_OFF_TIMEOUT, 3000);

// set 15 sec

Settings.System.putInt(m_context.getContentResolver(),

Settings.System.SCREEN_OFF_TIMEOUT, 15000);

// wait 200 sec till get response from BroadcastReceiver on Screen Off

mSync.doWait(wait*1000);

// set previous settings

Settings.System.putInt(m_context.getContentResolver(),

Settings.System.SCREEN_OFF_TIMEOUT, defTimeOut);

// switch back previous state

Settings.System.putInt(

m_context.getContentResolver(),

Settings.System.STAY_ON_WHILE_PLUGGED_IN,

BatteryManager.BATTERY_PLUGGED_USB);

m_context.unregisterReceiver(mReceiver);

}

public void broadCastListenerCallBack__ScreenOff_onResponse() {

mSync.doNotify();

}

....

AndroidSynchronize类

public class AndroidSynchronize {

public void doWait(long l){

synchronized(this){

try {

this.wait(l);

} catch(InterruptedException e) {

}

}

}

public void doNotify() {

synchronized(this) {

this.notify();

}

}

public void doWait() {

synchronized(this){

try {

this.wait();

} catch(InterruptedException e) {

}

}

}

}
