方法一：
复制代码 代码如下:
<uses-permission android:name="android.permission.wake_lock" />
private powermanager powermanager = null;
private wakelock wakelock = null;
powermanager = (powermanager) this.getsystemservice(service.power_service);
wakelock = this.powermanager.newwakelock(powermanager.screen_dim_wake_lock, "my lock");
//是否需计算锁的数量
wakelock.setreferencecounted(false);
//请求常亮，onresume()
wakelock.acquire();
//取消屏幕常亮，onpause()
wakelock.release();
方法二:
直接在oncreate()里，不用权限
getwindow().addflags(windowmanager.layoutparams.flag_keep_screen_on);
