今天又用到了PopWindow，所以决定对Popwindow做个总结，首先看创建PopWindow相关代码

class CityPopupWindow extends PopupWindow {        public CityPopupWindow(View view, int width, int height) {            super(view, width, height);        }        @Override        public void dismiss() {            //popwindow背景消失动画            view_bg.startAnimation(AnimationUtils.loadAnimation(context,                    R.anim.bg_out_anim));            view_bg.setVisibility(View.GONE);            super.dismiss();        }    }

其中view_bg是整体背景，就是在Activity的layout中加了一个遮罩层，代码如下

<?xml version="1.0" encoding="utf-8"?><FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    ><LinearLayout    android:layout_width="match_parent"    android:layout_height="match_parent"    android:background="@color/background"    android:orientation="vertical">    <include        android:id="@+id/action_bar"        layout="@layout/include_back_commit"        android:layout_width="match_parent"        android:layout_height="@dimen/view_height" />    <FrameLayout        android:layout_width="match_parent"        android:layout_height="match_parent">        <LinearLayout            android:id="@+id/layout_weekview"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:orientation="vertical"            ></LinearLayout>        <TextView            android:id="@+id/tv_tip"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:gravity="center"            android:text="加载中"            android:textColor="@color/darkgray"            android:visibility="visible" />    </FrameLayout></LinearLayout>    <View        android:id="@+id/sceduleview_bg"        android:layout_width="fill_parent"        android:layout_height="fill_parent"        android:visibility="gone"        android:background="@color/translucent_over_background"/></FrameLayout>

下面是初始化PopWindow的代码

    public void initPopWindowView(AppointmentExt appointment) {        // // 获取自定义布局文件        View dialogView = getLayoutInflater().inflate(R.layout.popwindow_scedule,                null, false);        cityPopwindow = new CityPopupWindow(dialogView, RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);        SimpleDraweeView headicon = (SimpleDraweeView) dialogView.findViewById(R.id.sdv_headicon);        TextView title = (TextView) dialogView.findViewById(R.id.tv_title);        TextView content = (TextView) dialogView.findViewById(R.id.tv_content);        TextView status = (TextView) dialogView.findViewById(R.id.tv_status);        User user = appointment.getUser();;        ImageUtils.setSimpleDrawView(headicon, user.getAvatar());        content.setText(StringUtils.subStrSensitive(appointment.getTopic().getTitle(), 28));        status.setText(TransUtils.getAppointStatus( appointment.getAppoint().getStatus()));        // 设置Pop响应外部区域焦点        cityPopwindow.setOutsideTouchable(true);        cityPopwindow.setBackgroundDrawable(new BitmapDrawable());        // 设置Pop入场和出场动画效果        cityPopwindow.setAnimationStyle(R.style.pop_anim);        // 设置Pop响应内部区域焦点        cityPopwindow.setFocusable(true);    }

然后是显示Popwindow

initPopWindowView();        view_bg.setVisibility(View.VISIBLE);        view_bg.startAnimation(AnimationUtils.loadAnimation(context,                R.anim.bg_in_anim));        cityPopwindow.showAtLocation(weekView, Gravity.NO_GRAVITY, (int) eventRect.left, (int) eventRect.centerY());

下面是相关的style和动画

pop出场入场style

 <style name="pop_anim">        <item name="android:windowEnterAnimation">@anim/pop_in_anim</item>        <item name="android:windowExitAnimation">@anim/pop_out_anim</item>    </style>

pop_in_anim

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android">    <scale        android:interpolator="@android:anim/accelerate_interpolator"        android:fromXScale="0%"        android:fromYScale="0%"        android:toXScale="100%"        android:toYScale="100%"        android:duration="300" /></set>

pop_out_anim

<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android">    <scale        android:interpolator="@android:anim/accelerate_interpolator"        android:fromXScale="100%"        android:fromYScale="100%"        android:toXScale="0%"        android:toYScale="0%"        android:duration="300" /></set>

view_bg显示动画 bg_in_anim

<?xml version="1.0" encoding="utf-8"?><alpha xmlns:android="http://schemas.android.com/apk/res/android"    android:fromAlpha="0.0"    android:toAlpha="1.0"    android:startOffset="200"    android:fillAfter="true"    android:duration="300"/>

view_bg消失动画 bg_out_anim

<?xml version="1.0" encoding="utf-8"?><alpha xmlns:android="http://schemas.android.com/apk/res/android"    android:fromAlpha="1.0"    android:toAlpha="0.0"    android:fillAfter="true"    android:duration="300"/>
