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。
1,通用PopupWindow,几行代码搞定PopupWindow弹窗
2, 通用PopupWindow,几行代码搞定PopupWindow弹窗(续)
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:
- Add it in your root build.gradle :
allprojects {
epositories {
...
maven {
url 'https://jitpack.io'
}
}
- Add the dependency
dependencies {
compile 'com.github.pinguo-zhouwei:CustomPopwindow:2.1.0'
}
示例效果图:
v2.0.0:
- 1,添加弹出PopupWindow同时背景变暗的配置,添加配置动画
v2.1.0:
- 1, 兼容Android 6.0 、Android 7.0 点击PopupWindow 之外的区域可以控制 显示/关闭popupWindow
- 2, 可以获取到PopupWindow实例
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);
更新3:点击PopupWindow以外区域不让关闭(默认DisMiss):
mPopWindow = new CustomPopWindow.PopupWindowBuilder(this)
.setView(view)
.enableOutsideTouchableDissmiss(false)// 设置点击PopupWindow之外的地方,popWindow不关闭,如果不设置这个属性或者为true,则关闭
.create();
mPopWindow.showAsDropDown(mButton7,0,10);
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();
}
