Android实现从底部弹出的Dialog的实例代码

Dialog dialog = new Dialog(context, R.style.ActionSheetDialogStyle);    //填充对话框的布局    inflate = LayoutInflater.from(context).inflate(R.layout.dialog_layout, null);    // setCancelable(iscancelable);//点击外部不可dismiss    //setCanceledOnTouchOutside(isBackCanCelable);    //初始化控件    spinner = (Spinner) inflate.findViewById(R.id.sp);    beizhu = (TextView) inflate.findViewById(R.id.beizhu);    btn_cancel = (Button) inflate.findViewById(R.id.btn_cancel);    btn_ok = (Button) inflate.findViewById(R.id.btn_ok);    //将布局设置给Dialog    taskProgress.setContentView(inflate);    //获取当前Activity所在的窗体    Window dialogWindow = taskProgress.getWindow();    //设置Dialog从窗体底部弹出    dialogWindow.setGravity(Gravity.BOTTOM);    //获得窗体的属性    WindowManager.LayoutParams lp = dialogWindow.getAttributes();    //如果没有这行代码，弹框的内容会自适应，而不会充满父控件    lp.width = WindowManager.LayoutParams.MATCH_PARENT;    lp.y = 40;//设置Dialog距离底部的距离    //将属性设置给窗体    dialogWindow.setAttributes(lp);    dialog .show();//显示对话框    在需要消失地方直接    dialog.dismiss();
