如何在Android中将手机置于暗淡模式？

Question

I want to put my phone in dim mode using my application. It seems phone's home screen will be in deem mode. If I going to use Power Manager class then it will drain battery. How can I do this then? Can any one give some sample code?

Answer 1

In my case I just update the Android Default Settings,

android.provider.Settings.System.putInt(cr,android.provider.Settings.System.SCREEN_BRIGHTNESS, 1);

Note: here 1 is value for dim (low) (values 0 t0 250) , and cr is ContentResolver's object

For this you have to mentioned permission in manifest file,

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