Question

我有一项提升屏幕亮度的活动

/* turn screen brightness up */ this.getWindow().getAttributes().screenBrightness = 1;

我发现这个内置的android功能会使某些手机崩溃。

是否有更普遍的方法来提升屏幕亮度？

Answer 1

设置属性的正确方法是setAttributes()：

WindowManager.LayoutParams lp = this.getWindow().getAttributes();
lp.screenBrightness = 1;
this.getWindow().setAttributes(lp);

Answer 2

您可以尝试几乎为1的值。例如：0.999。

Answer 3

如果您希望触摸事件通过，则需要做的不仅仅是设置亮度。您需要设置视图和布局参数 view.setFocusable(false); view.setClickable(false); view.setKeepScreenOn(false); view.setLongClickable(false); view.setFocusableInTouchMode(false);

layoutParams.height = LayoutParams.FILL_PARENT; layoutParams.width = LayoutParams.FILL_PARENT; layoutParams.flags = 280; // You can try LayoutParams.FLAG_FULLSCREEN too layoutParams.format = PixelFormat.TRANSLUCENT; // You can try different formats layoutParams.windowAnimations = android.R.style.Animation_Toast; // You can use only animations that the system to can access layoutParams.type = LayoutParams.TYPE_SYSTEM_OVERLAY; layoutParams.gravity = Gravity.BOTTOM; layoutParams.x = 0; layoutParams.y = 0; layoutParams.verticalWeight = 1.0F; layoutParams.horizontalWeight = 1.0F; layoutParams.verticalMargin = 0.0F; layoutParams.horizontalMargin = 0.0F;
