Android中各类Dialog实例——交互

浅浅的花香味﹌ 2022-04-12 07:53 232阅读 0赞

今天打开技术博客发现自己的上一篇技术博客已经是去年11月份的了。但凡是生活中或是学习中的许多事情我们一直都有在做，只是并没有一直在记录。有时候脑袋真的很像存储机制，即使脑容量有着科学研究的浩如宇宙，但大脑之所谓有“大”来修饰，终归还是会有溢出的时候。所以对于学习生活中运行过的“程序”所残留的内存，要么释放，要么记录加以保管，而技术博客正是这样的存在。

做技术的不空谈，现在开始。。。

在androidApp的开发中会遇到许多需要人机交互的组件，借此获取用户所作出的选择或是反馈。这样的一些组件到底有多少种又该如何实例呢？ 看下图：

而这些组件各自的效果 如下图：

进行插入图片操作时很想吐槽该网站。。。。。

具体代码实现如下：

    布局文件：

还有相应的两个布局文件，即自定义对话框和popup window实现的对话框中的布局文件：

<?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="match_parent"

            android:layout_height="match_parent"
            android:background="@drawable/abc123" >
    
            <Button
                android:id="@+id/diaCusPopupSure"
                android:layout_width="wrap_content"

                android:layout_marginBottom="18dp"
                android:text="是否确定您的选择？"
                android:textSize="20sp" />
    
            <TextView
                android:id="@+id/textView2"
                android:layout_width="wrap_content"

                android:layout_centerHorizontal="true"
                android:layout_marginBottom="50dp"
                android:text="这是通过popup window来实现"
                android:textSize="20sp" />
    
        </RelativeLayout>
    
    </LinearLayout>

至此，android中各类Dialog的实例已经全贴上去了。希望我的总结对大家有所帮助。

晴时有风阴有时雨，听说~下雨天技术博客和敲代码更配哦。。。
