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

一、介绍

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

二、核心类PopWindow

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

三、使用方法

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);

四、使用封装

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);
}

/**
 * 以ListView方式向下弹出框
 *
 * @param activity
 * @param adapter
 * @param controlView    操作显示出弹框的按钮
 * @param rotateView     要旋转的按钮
 * @param openAnim       旋转按钮开启动画
 * @param closeAnim      旋转按钮关闭动画
 * @param rotateViewAnim 是否显示旋转动画
 * @param margins        margins[0]:leftMargin、margins[1]:topMargin、margins[2]:rightMargin、margins[3]:bottomMargin
 * @param listener
 * @return
 */
public static PopWindow showPopDownList(Activity activity, final BaseAdapter adapter, View controlView, View rotateView,
                                        Animation openAnim, Animation closeAnim, boolean rotateViewAnim, int[] margins,
                                        AdapterView.OnItemClickListener listener) {
    final ListView listView = new ListView(activity);
    listView.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT));
    listView.setDivider(null);
    listView.setOnItemClickListener(listener);
    listView.setAdapter(adapter);

    int leftMargin = 0, topMargin = 0, rightMargin = 0, bottomMargin = 0;
    if (margins != null) {
        for (int i = 0; i < margins.length; i++) {
            if (i == 0) {
                leftMargin = margins[i];
            } else if (i == 1) {
                topMargin = margins[i];
            } else if (i == 2) {
                rightMargin = margins[i];
            } else if (i == 3) {
                bottomMargin = margins[i];
            }
        }
    }

    PopWindow popWindow = new PopWindow.Builder(activity)
            .setStyle(PopWindow.PopWindowStyle.PopDown)
            .setView(listView)
            .setControlViewAnim(rotateView, openAnim, closeAnim, rotateViewAnim)
            .setPopWindowMargins(leftMargin, topMargin, rightMargin, bottomMargin)
            .create();
    popWindow.show(controlView);
    return popWindow;
}

}
