控制屏幕常亮不熄灭

方式1

1. 代码里调用

val pm = context!!.getSystemService(Context.POWER_SERVICE) as PowerManager
val wakeLock = pm.newWakeLock(
            PowerManager.FULL_WAKE_LOCK or PowerManager.ACQUIRE_CAUSES_WAKEUP,
            ""
        )
wakeLock.acquire()
        

2. 清单文件需要配置权限

<uses-permission android:name="android.permission.WAKE_LOCK"/>

3. 取消控制屏幕常亮不熄灭得控制

swakeLock.release()

方式2

利用View提供的方法

/**
     * Controls whether the screen should remain on, modifying the
     * value of {@link #KEEP_SCREEN_ON}.
     *
     * @param keepScreenOn Supply true to set {@link #KEEP_SCREEN_ON}.
     *
     * @see #getKeepScreenOn()
     *
     * @attr ref android.R.styleable#View_keepScreenOn
     */
    public void setKeepScreenOn(boolean keepScreenOn) {
        setFlags(keepScreenOn ? KEEP_SCREEN_ON : 0, KEEP_SCREEN_ON);
    }

1. 屏幕常亮

  button.keepScreenOn = true

2. 取消常亮

 button.keepScreenOn = false
