封装通用PopupWindow,CustomPopWindow,使用链式的方式配置并显示

由于每次写PopupWindow都要写很多重复代码,因此简单的封装了一个CustomPopWindow.封装了PopupWindow 的一些常用API,使用Builder模式,就像写AlertDialog 一样,链式配置。

Usage

由于 1.0.0 版本 是托管到 Jcenter的,添加如下依赖:

Add the dependency to your build.gradle.

dependencies {
    compile 'com.example.zhouwei.library:library:1.0.0'
}

2.x 版本 代码托管到Jitpack, 需要如下依赖:

  1. Add it in your root build.gradle :
    
allprojects {
    epositories {
        ...
        maven {
            url 'https://jitpack.io'

        }

}
  1. Add the dependency
dependencies {
	compile 'com.github.pinguo-zhouwei:CustomPopwindow:2.0.0'
}

更新日志:(添加弹出PopupWindow同时背景变暗的配置,添加配置动画)

更新1:背景变暗配置示例:

   //创建并显示popWindow
 mCustomPopWindow= new CustomPopWindow.PopupWindowBuilder(this)
                .setView(contentView)
                .enableBackgroundDark(true) //弹出popWindow时,背景是否变暗
                .setBgDarkAlpha(0.7f) // 控制亮度
                .create()
                .showAsDropDown(mButton5,0,20);

更新2:显示消失动画配置:

 CustomPopWindow popWindow = new CustomPopWindow.PopupWindowBuilder(this)
                .setView(R.layout.pop_layout1)
                .setFocusable(true)
                .setOutsideTouchable(true)
                .setAnimationStyle(R.style.CustomPopWindowStyle) // 添加自定义显示和消失动画
                .create()
                .showAsDropDown(mButton1,0,10);

1,简便写法

CustomPopWindow popWindow = new CustomPopWindow.PopupWindowBuilder(this)
                .setView(R.layout.pop_layout1)//显示的布局,还可以通过设置一个View
           //     .size(600,400) //设置显示的大小,不设置就默认包裹内容
                .setFocusable(true)//是否获取焦点,默认为ture
                .setOutsideTouchable(true)//是否PopupWindow 以外触摸dissmiss
                .create()//创建PopupWindow
                .showAsDropDown(mButton1,0,10);//显示PopupWindow

以上就是弹出一个简单的PopupWindow,是不是看起来很优雅和简单,还可以简单一点:

CustomPopWindow popWindow = new CustomPopWindow.PopupWindowBuilder(this)
                .setView(R.layout.pop_layout1)//显示的布局
                .create()//创建PopupWindow
                .showAsDropDown(mButton1,0,10);//显示PopupWindow

如果是一个简单的只展示文案的弹窗,就可以只设置一个View,就可以了,很简单吧!!!

2,展示一个PopupWindow 弹窗菜单(像手机QQ,微信的顶部菜单)

View contentView = LayoutInflater.from(this).inflate(R.layout.pop_menu,null);
        //处理popWindow 显示内容
        handleLogic(contentView);
        //创建并显示popWindow
        mCustomPopWindow= new CustomPopWindow.PopupWindowBuilder(this)
                .setView(contentView)
                .create()
                .showAsDropDown(mButton3,0,20);

如果PopupWindow 展示的内容需要在程序代码中设置或者响应点击事件等,可以现获取到这个View,然后处理一些显示和点击事件逻辑,再交给CustomPopWindow 创建显示。比如响应菜单点击事件的逻辑处理:

 /**
     * 处理弹出显示内容、点击事件等逻辑
     * @param contentView
     */
    private void handleLogic(View contentView){
        View.OnClickListener listener = new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(mCustomPopWindow!=null){
                    mCustomPopWindow.dissmiss();
                }
                String showContent = "";
                switch (v.getId()){
                    case R.id.menu1:
                        showContent = "点击 Item菜单1";
                        break;
                    case R.id.menu2:
                        showContent = "点击 Item菜单2";
                        break;
                    case R.id.menu3:
                        showContent = "点击 Item菜单3";
                        break;
                    case R.id.menu4:
                        showContent = "点击 Item菜单4";
                        break;
                    case R.id.menu5:
                        showContent = "点击 Item菜单5" ;
                        break;
                }
                Toast.makeText(MainActivity.this,showContent,Toast.LENGTH_SHORT).show();
            }
        };
        contentView.findViewById(R.id.menu1).setOnClickListener(listener);
        contentView.findViewById(R.id.menu2).setOnClickListener(listener);
        contentView.findViewById(R.id.menu3).setOnClickListener(listener);
        contentView.findViewById(R.id.menu4).setOnClickListener(listener);
        contentView.findViewById(R.id.menu5).setOnClickListener(listener);
    }
}

3,展示一个ListView,其实跟上面是一样的,这里贴一下实例代码:

private void showPopListView(){
        View contentView = LayoutInflater.from(this).inflate(R.layout.pop_list,null);
        //处理popWindow 显示内容
        handleListView(contentView);
        //创建并显示popWindow
        mListPopWindow= new CustomPopWindow.PopupWindowBuilder(this)
                .setView(contentView)
                .size(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT)//显示大小
                .create()
                .showAsDropDown(mButton4,0,20);
    }

    private void handleListView(View contentView){
        RecyclerView recyclerView = (RecyclerView) contentView.findViewById(R.id.recyclerView);
        LinearLayoutManager manager = new LinearLayoutManager(this);
        manager.setOrientation(LinearLayoutManager.VERTICAL);
        recyclerView.setLayoutManager(manager);
        MyAdapter adapter = new MyAdapter();
        adapter.setData(mockData());
        recyclerView.setAdapter(adapter);
        adapter.notifyDataSetChanged();

    }
