写输入popupwindow 的布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    xmlns:tools="http://schemas.android.com/tools"
    android:orientation="vertical">

    <TextView
        android:id="@+id/camera"
        android:layout_width="match_parent"

        />

    <View
        android:layout_width="match_parent"
        android:layout_height="@dimen/dp_1"

    <TextView
        android:id="@+id/cancel"

        android:text="取消"
        android:textColor="@color/bottom_blue"
        android:textSize="@dimen/sp_20"

        />


</LinearLayout>

 

 

//写入布局后，需要设置它的样式

<style name="DialogTheme" parent="@android:style/Theme.Dialog">
    <!-- 边框 -->
    <item name="android:windowFrame">@null</item>
    <!-- 是否浮现在activity之上 -->
    <item name="android:windowIsFloating">true</item>
    <!-- 半透明 -->
    <item name="android:windowIsTranslucent">true</item>
    <!-- 无标题 -->
    <item name="android:windowNoTitle">true</item>
    <item name="android:background">@android:color/transparent</item>
    <!-- 背景透明 -->
    <item name="android:windowBackground">@android:color/transparent</item>
    <!-- 模糊 -->
    <item name="android:backgroundDimEnabled">true</item>
    <!-- 遮罩层 -->
    <item name="android:backgroundDimAmount">0.5</item>
</style>

 

//接下来就要在我们的点击事件里写入主要代码
