对Android的底部弹窗、顶部弹窗菜单及自定义界面的使用封装。
CSDN：http://blog.csdn.net/hmyang314/article/details/70613478
主要是用于在弹窗中显示一些有限的菜单项，也支持添加自定义View，有如下3中弹出方式：
1、底部弹出，主要参考默认风格是参考IOS的UIAlertController，可以添加自定义View；
2、底部弹出，从顶部向下弹出的效果，同时支持控制按钮执行动画，默认是旋转动画；
3、屏幕中间弹出
PopWindow采用Build模式，可以像AlertDialog一样方便的使用，通过PopWindowStyle控制弹窗的显示方式：
public enum PopWindowStyle {
PopUp, PopDown, PopAlert
}
控制不同的弹窗的主要类是：PopUpWindow、PopDownWindow、PopAlertDialog
第一种
PopWindow popWindow = new PopWindow.Builder(this)
.setStyle(PopWindow.PopWindowStyle.PopUp)
.setTitle("注意")
.setMessage("今天天气不错")
.addItemAction(new PopItemAction("选项1"))
.addItemAction(new PopItemAction("选项2", PopItemAction.PopItemStyle.Normal))
.addItemAction(new PopItemAction("选项3", PopItemAction.PopItemStyle.Normal, new PopItemAction.OnClickListener() {
@Override
public void onClick() {
Toast.makeText(MainActivity.this, "选项3", Toast.LENGTH_SHORT).show();
}
}))
.addItemAction(new PopItemAction("确定", PopItemAction.PopItemStyle.Warning, new PopItemAction.OnClickListener() {
@Override
public void onClick() {
Toast.makeText(MainActivity.this, "确定", Toast.LENGTH_SHORT).show();
}
}))
.addItemAction(new PopItemAction("取消", PopItemAction.PopItemStyle.Cancel))
.create();
popWindow.show();
效果图：
第二种
View customView = View.inflate(this, R.layout.layout_test, null);
new PopWindow.Builder(this)
.setStyle(PopWindow.PopWindowStyle.PopDown)
.setIsShowCircleBackground(false)
.addItemAction(new PopItemAction("选项1"))
.addContentView(customView)
.addItemAction(new PopItemAction("选项2"))
.addItemAction(new PopItemAction("取消", PopItemAction.PopItemStyle.Cancel, new PopItemAction.OnClickListener() {
@Override
public void onClick() {
Toast.makeText(MainActivity.this, "取消", Toast.LENGTH_SHORT).show();
}
}))
.setPopWindowMargins(dip2px(10), dip2px(0), dip2px(10), dip2px(0))
.setControlViewAnim(mArrowIv, R.anim.btn_rotate_anim_1, R.anim.btn_rotate_anim_2, true)
.show(view);
效果图：
在demo中有个PopWindowController类，是对一些特殊的使用进行了再次封装，大家可以根据自己的实际使用情况进行封装。
public class PopWindowController {
public static PopWindow showPopDownList(Activity activity, BaseAdapter adapter, View controlView, View rotateView,
int[] margins, AdapterView.OnItemClickListener listener) {
return showPopDownList(activity, adapter, controlView, rotateView, true, margins, listener);
}
public static PopWindow showPopDownList(Activity activity, BaseAdapter adapter, View controlView, View rotateView,
boolean rotateViewAnim, int[] margins, AdapterView.OnItemClickListener listener) {
Animation openAnim = AnimationUtils.loadAnimation(activity, R.anim.btn_rotate_anim_1);
Animation closeAnim = AnimationUtils.loadAnimation(activity, R.anim.btn_rotate_anim_2);
return showPopDownList(activity, adapter, controlView, rotateView, openAnim, closeAnim, rotateViewAnim, margins, listener);
}
public static PopWindow showPopDownList(Activity activity, BaseAdapter adapter, View controlView, View rotateView, int openAnimId,
int closeAnimId, boolean rotateViewAnim, int[] margins,
AdapterView.OnItemClickListener listener) {
Animation openAnim = AnimationUtils.loadAnimation(activity, openAnimId);
Animation closeAnim = AnimationUtils.loadAnimation(activity, closeAnimId);
return showPopDownList(activity, adapter, controlView, rotateView, openAnim, closeAnim, rotateViewAnim, margins, listener);
}
/**

final ListView listView = new ListView(activity);

listView.setAdapter(adapter);
int leftMargin = 0, topMargin = 0, rightMargin = 0, bottomMargin = 0;
