PopWindow

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

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();

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);

更多效果请看代码。

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;
}
