android圆角dialog,并限制宽度和高度

        AlertDialog.Builder builder = new AlertDialog.Builder(getContext());        View contentView = getActivity().getLayoutInflater().inflate(R.layout.layout_dialog_contact, null);        builder.setView(contentView);        AlertDialog dialog = builder.create();        dialog.getWindow().setBackgroundDrawable(new BitmapDrawable()); // 背景透明.        dialog.setCanceledOnTouchOutside(false); // 点击外部不消失.        dialog.getWindow().setGravity(Gravity.CENTER); // 位置.        dialog.show();        WindowManager m = getActivity().getWindowManager();        Display d = m.getDefaultDisplay(); // 获取屏幕宽、高用        WindowManager.LayoutParams p = dialog.getWindow().getAttributes(); // 获取对话框当前的参数值        p.height = (int) (d.getHeight() * 0.4); // 高度设置为屏幕的0.4        p.width = (int) (d.getWidth() * 0.9); // 宽度设置为屏幕的0.9        dialog.getWindow().setAttributes(p);

使用 shape 做背景实现圆角的dialog

注意:dialog.getWindow().setAttributes(p); 须在 show() 方法之后调用
