对话框交互 Dialog Android

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：

package com.example.dialogtest;

import java.util.ArrayList;

import android.os.Bundle;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.PopupWindow;
import android.widget.Toast;
import android.app.ActionBar.LayoutParams;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.ProgressDialog;
import android.content.DialogInterface;
import android.graphics.drawable.BitmapDrawable;
import android.graphics.drawable.ColorDrawable;

public class MainActivity extends Activity implements Runnable {//Runnable线程接口 下面写进度条选择框时模拟使用

            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。。。
