在Android中如何设置屏幕亮度？

我想要一个使用

SeekBar

调整屏幕亮度的对话框

如何使用调整屏幕亮度的

SeekBar

显示自定义对话框？

。这将改变窗口的屏幕亮度，而不是整个系统的亮度

        // Make the screen full bright for this activity.
        WindowManager.LayoutParams lp = getWindow().getAttributes();
        lp.screenBrightness = 1.0f;

        getWindow().setAttributes(lp);

这应该对你有帮助

pdlg = ProgressDialog.show(getParent(), "Loading...", ""); 
WindowManager.LayoutParams lp = pdlg.getWindow().getAttributes();
p.dimAmount=0.0f;        //Dim Amount
pdlg.getWindow().setAttributes(lp);  //Applying properties to progress dialog
pdlg.dismiss(); //Dismiss the dialog

嘿，您可以这样设置系统亮度：

 //Set the system brightness using the brightness variable value
System.putInt(cResolver, System.SCREEN_BRIGHTNESS, brightness);
//Get the current window attributes
LayoutParams layoutpars = window.getAttributes();
//Set the brightness of this window
layoutpars.screenBrightness = brightness / (float)255;
//Apply attribute changes to this window
window.setAttributes(layoutpars);
