你如何让你的活动的当前屏幕亮度？

以下方法工作正常，通过调用设置亮度为最大 setBrightness（100）：

Following method works fine for setting the brightness to max by calling setBrightness(100):

private void setBrightness(int brightness) {
    WindowManager.LayoutParams layoutParams = getWindow().getAttributes();
    layoutParams.screenBrightness = brightness/100.0f;

}

我试着去实现以下目标：

Im trying to achieve the following:

1. 启动活动和保存当前亮度值
2. 设置亮度最大值

推荐答案

尝试

int curBrightnessValue = android.provider.Settings.System.getInt(getContentResolver(), android.provider.Settings.System.SCREEN_BRIGHTNESS);

然后

   WindowManager.LayoutParams layoutParams = getWindow().getAttributes();
    layoutParams.screenBrightness = curBrightnessValue/100.0f;
    getWindow().setAttributes(layoutParams);
