Android中关于Dialog滑动弹出的简单动画的设置

弹出位置–>>> 屏幕中间

//获取当前布局的Window
Window window = getWindow();
//设置无标题栏
window.requestFeature(Window.FEATURE_NO_TITLE);
//背景为透明
window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
//设置Dialog的布局
setContentView(R.layout.dialog_common);

WindowManager.LayoutParams params = window.getAttributes();
//显示隐藏的动画效果
params.windowAnimations = R.style.MyDialogAnimationCenter;
params.gravity = Gravity.CENTER;            //位置在屏幕处于居中位置

<!-- Dialog从center弹出的动画效果-->
<style name="MyDialogAnimationCenter" >
<item name="android:windowEnterAnimation">@anim/dialog_bottom_center_enter</item>
<item name="android:windowExitAnimation">@anim/dialog_bottom_center_exit</item>
