4￥3995￥13006￥7987￥4998￥4689￥37610￥298[AndroidTips]Android中系统自带的锁：WalkLock、KeyguardLock
- 坚持,淡定 - ITeye技术网站
博客分类：
WalkLock - 顾名思义 唤醒锁 点亮屏幕用的
KeyguardLock - 顾名思义 键盘锁 解锁键盘用的
详细介绍：
1： WalkLock 唤醒锁
- WalkLock真的能点亮屏幕吗？
答案是肯定的。 可是有时候为什么不点亮屏幕，这个就是参数设置的问题了。
PowerManager.newWakeLock(PowerManager.FULL_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "Gank");
PowerManager.FULL_WAKE_LOCK 这个参数是手机点亮的程度，（什么Cpu，屏幕亮度，键盘灯）
PowerManager.ACQUIRE_CAUSES_WAKEUP 关键是这个参数的理解。
WalkLock点亮屏幕并非真的去点亮了屏幕，你可以理解为，它通过Android组件（Activity）去点亮了屏幕。
假如一个通知想去点亮屏幕，问题来了，它能点亮吗？ 肯定不行。
不过拥有这个PowerManager.ACQUIRE_CAUSES_WAKEU参数，你就可以点亮屏幕了。它使WalkLock不再依赖组件就可以点亮屏幕了。
- WalkLock如何获得屏幕的状态？
PowerManager.isScreenOn()方法；这个方法返回true: 屏幕是唤醒的
返回false:屏幕是休眠的
- WalkLock唤醒和休眠的方法？
WalkLock.aquire() 在屏幕休眠的状态下唤醒屏幕
WalkLock.release() 在屏幕点亮的状态下，使屏幕休眠。
WalkLock.release()这个方法有个需要注意的地方：
例如：WalkLockA对象先唤醒了屏幕再使屏幕休眠，ok没问题
屏幕本身就是唤醒状态，WalkLockA对象没有唤醒过屏幕，WalkLockA对象如果尝试使屏幕休眠。会产生一个异常 UnLock Sreen。
2:KeyguardLock 键盘锁
- KeyguardLock获得当前屏幕是否解锁？
KeygroundManager.inKeyguardRestrictedInputMode() 返回true表示键盘锁住， 返回false表示键盘解锁中
- KeyguardLock给屏幕解锁和上锁？
KeyguardLock.disableKeyguard()解锁键盘
KeyguardLock.reenableKeyguard()锁键盘
KeyguardLock没有上面唤醒锁的问题，就是无论你键盘是否由KeyguardLockA解锁，你调用KeyguardLockA对象的reenableKeyguard（）方法都不会有异常。
这两把锁一些概念性的理解，假如你认为你获得了一个键盘锁对象，你就可以锁屏幕了。这个就大错特错了。
你锁不了其他程序打开的屏幕（如果可以的话，一个for循环一直锁你屏幕，你哭都没眼泪）
你可以控制自己的锁，别想着别人的锁。
最后总结下用法：
一般这两把锁都是配合使用的，你解锁屏幕的时候肯定不希望屏幕漆黑一片。关闭键盘锁的时候希望屏幕也同时休眠。
1：我尝试手动关闭屏幕，可是总继续亮那么一小会。
2：如果手机自动关闭屏幕的话，不会有这个问题。
public void unlockScreen() {
// 获取PowerManager的实例
PowerManager pm = (PowerManager) mContext
.getSystemService(Context.POWER_SERVICE);
// 得到一个WakeLock唤醒锁
mWakelock = pm.newWakeLock(PowerManager.FULL_WAKE_LOCK
| PowerManager.ACQUIRE_CAUSES_WAKEUP
| PowerManager.ON_AFTER_RELEASE, "SimpleTimer");
if (!mWakelock.isHeld()) {
// 唤醒屏幕
mWakelock.acquire();
// 获得一个KeyguardManager的实例
km = (KeyguardManager) mContext
.getSystemService(Context.KEYGUARD_SERVICE);
// 得到一个键盘锁KeyguardLock
mKeyguardLock = km.newKeyguardLock("SimpleTimer");
if (km.inKeyguardRestrictedInputMode()) {
// 解锁键盘
mKeyguardLock.disableKeyguard();
注意，这里使用的mWakelock.isHeld())来判断屏幕当前是否是休眠状态，从Android 2.1 API Level7开始增加了一个判断屏幕是否处于点亮状态可以使用public boolean isScreenOn ()这个方法。
锁屏幕的代码是
public void lockScreen() {
// release screen
if (!km.inKeyguardRestrictedInputMode()) {
mKeyguardLock.reenableKeyguard();
// 使屏幕休眠
if (mWakelock.isHeld()) {
mWakelock.release();
