如何实现PopWindows的详细案例
这是项目的俯瞰图：
现在首先是main的xml文件布局：
<RelativeLayout xmlns:
android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<LinearLayout
android:gravity="center_horizontal"
android:id="@+id/mybutton"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:orientation="horizontal">
<TextView
android:id="@+id/aboutname"
android:textSize="28sp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="京" /> <ImageView
android:paddingTop="5dp"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:src="@drawable/jiantou"/>
</LinearLayout>
</RelativeLayout>
界面如图：
下面是需要悬浮的布局文件。效果如图：
其xml文件如下：
<?xml version="1.0" encoding="utf-8"?>
