A) pass through system SettingProvider data base interface
android.provider.Settings.System.getInt
(android.provider.Settings.System.SCREEN_BRIGHTNESS)
The function screen brightness value current to obtain system.
Wherein android.provider.Settings.System.SCREEN_BRIGHTNESS is a constant value, generation
What table was obtained is the meaning of the current screen brightness of system.
2nd, detect whether video is played, be described in detail as follows
A) when video is played, we can arrange one and play flag bit isVideoOn (only one boolean's change
Amount, for indicating current video broadcast state) it is true (true)；
B) when stopping playing video, it is false (vacation) that we can arrange one and play flag bit isVideoOn；
C) by the state of detection flag bit isVideoOn, we just can determine that current video playback situation.
If 3 when detecting under video state is played, we just arrange 60%- of the screen intensity for maximum brightness
90% (in the case of video is played, it is the bright environment of a comparison for 60%-90% to play brightness, is relatively suitable for video and broadcasts
The brightness that puts).In android system, the brightness of screen is to be stored in data base SettingProvider (database-name)
In, the change in system meeting monitored data storehouse, after the brightness value in data base changes, system can be perceived at once,
And the operation of the screen intensity of triggering modification immediately.
The concrete flow process for arranging screen intensity is as follows：
A) in android system, the excursion of brightness is 0-255.
B) by the setting interface of system SettingProvider data base
Android.provider.Settings.System.putInt (the write letter of SettingProvider data base
Number) a shaping brightness value is written in data base.
C) maximum brightness is 255, then the 90% of 255 is 230, so we are written to data base by 230
In SettingProvider, the brightness of such system is just adjusted to the 90% of maximum brightness.
If detected after stopping plays, we can read out the screen brightness value h1 of default storage, then by the
Data base SettingProvider write interface described in three
Android.provider.Settings.System.putInt, this brightness value of h1 is written to data base
In SettingProvider, the screen intensity of such system will become the brightness for turning to original luminance value h1.
