PopWindow

对Android的底部弹窗，顶部弹窗菜单及自定义界面的使用封装。

GitHub：https：//github.com/HMY314/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

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：

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;

}

}
