android - 如何从API 4禁用自动亮度模式？

Question

我可以从api等级8开始禁用自动亮度。 旧版本怎么样？ 如何从API 4中禁用自动亮度模式？

Answer 1

根据Google android dashboard，只有0.3％的设备使用API​​级别4.感染只有3.5％的设备低于API级别7.因此我猜您不必担心API级别4或者此类问题任何低于API等级8的东西都会浪费时间......

private static final String SCREEN_BRIGHTNESS_MODE = "screen_brightness_mode";
private static final int SCREEN_BRIGHTNESS_MODE_MANUAL = 0;
private static final int SCREEN_BRIGHTNESS_MODE_AUTOMATIC = 1; 

Settings.System.putInt(resolver, SCREEN_BRIGHTNESS_MODE, mode); 
Settings.System.putInt(resolver, Settings.System.SCREEN_BRIGHTNESS, lev);
