1.设置透明度(Dialog自身的透明度)
WindowManager.LayoutParams lp=dialog.getWindow().getAttributes();
lp.alpha=1.0f;
dialog.getWindow().setAttributes(lp);
alpha在0.0f到1.0f之间。1.0完全不透明,0.0f完全透明
2.设置黑暗度(Dialog自身的黑暗度)
dialog.setContentView(R.layout.dialog);
WindowManager.LayoutParams lp=dialog.getWindow().getAttributes();
lp.dimAmount=1.0f;
dialog.getWindow().setAttributes(lp);
dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
dimAmount在0.0f和1.0f之间,0.0f完全不暗,1.0f全暗
3.设置Dialog底背景模糊和黑暗度
WindowManager.LayoutParams.FLAG_BLUR_BEHIND(设置模糊)
WindowManager.LayoutParams.FLAG_DIM_BEHIND(设置暗淡)
4.清除Dialog底背景模糊和黑暗度
getDialog().getWindow().clearFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND | WindowManager.LayoutParams.FLAG_DIM_BEHIND)
