(一) 效果实现图

目标:通过一个SQLite的数据库的操作实现学生信息的增删改查
1)实现多个学生信息的添加和显示
2)用EditText实现姓名、年龄的输入,并有输入校验(空校验,数字校验)
3)用AutoCompleteTextView的实现专业的输入,并有提示功能。
4)通过CheckBox实现多门课程选择
5)通过Radio实现性别
6)点击提交按钮后,将输入的信息,用列表控件ListView显示在另一个Activity。

(三) 具体的编码实现

(1)注册

  1. 自定义StuInfo.java
package com.example.cungu.myapplication3;

import java.io.Serializable;

public class StuInfo implements Serializable {
    private String name;
    private String major;

    public StuInfo(String n, String m)
    {
        name=n;
        major=m;
    }

    public String getMajor() {
        return major;
    }
    public String getName() {
        return name;
    }

    public void setMajor(String major) {
        this.major = major;
    }
    
    public void setName(String name) {
        this.name = name;
    }
}

  1. 布局界面比较简单,主函数activity_stu.xml:
    在这里插入图片描述

activity_stu.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_stu);
        button_1 = (Button) findViewById(R.id.button_1);
        button_2 = (Button) findViewById(R.id.button_2);
        button_1.setOnClickListener(this);
        button_2.setOnClickListener(this);

  1. 显示选课列表Other2.xml:
    在这里插入图片描述

Other2.xml:

<?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:background="@drawable/pinkback"
    android:gravity="center"
    android:orientation="vertical">
    <!-- 显示选课清单-->
    <TextView
        android:id="@+id/stu_show2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="20dp"
        android:textColor="#5e9cff" />
</LinearLayout>

other2Activity.java

package com.example.cungu.myapplication2;

import android.graphics.Color;
import android.graphics.Typeface;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.SpannableString;
import android.text.Spanned;
import android.text.style.BackgroundColorSpan;
import android.text.style.ForegroundColorSpan;
import android.text.style.RelativeSizeSpan;
import android.text.style.StyleSpan;
import android.text.style.SuperscriptSpan;
import android.widget.TextView;

import java.util.ArrayList;

public class other2Activity extends AppCompatActivity {
    TextView stu_show2;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_other2);
        stu_show2 = (TextView) findViewById(R.id.stu_show2);

        Bundle bundle=getIntent().getExtras();//获得传值
        ArrayList<CouresInfo> coures=(ArrayList<CouresInfo>)bundle.get("coures");

        for (CouresInfo c: coures) {
            String list1 = c.getName()+" 已选课程有: " + "\n";
            String couresInfo = c.getCouresName() + "\n";
            //=========================字体样式设置============================================
            SpannableString text1=new SpannableString(list1);
            //设置前景色
            ForegroundColorSpan forcolor=new ForegroundColorSpan(Color.parseColor("#ef7a82"));
            text1.setSpan(forcolor,0,text1.length(),Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);//定位
            //设置背景色
            BackgroundColorSpan back=new BackgroundColorSpan(Color.parseColor("#80ffffff"));
            text1.setSpan(back,0,text1.length(),Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);//定位
            //设置文字相对大小
            RelativeSizeSpan relativeSizeSpan=new RelativeSizeSpan(1.5f);
            text1.setSpan(relativeSizeSpan,0,c.getName().length(),Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
            //设置上标
            SuperscriptSpan superscriptSpan=new SuperscriptSpan();
            text1.setSpan(superscriptSpan,0,c.getName().length(),Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

            text1.setSpan(styleSpan1,0,c.getName().length(),Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
            //================================================================================
            stu_show2.append(text1);
            stu_show2.append(couresInfo);
        }
    }
}

(3)配置文件

layout下: au_checkboxlist.xml、au_textview.xml、stu_list.xml
  1. 自定义选课时的checkbox样式au_checkboxlist.xml:
    在这里插入图片描述
<?xml version="1.0" encoding="utf-8"?>
<!-- 自定义选课时的checkbox样式 -->
<CheckBox
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:text="java"
    android:textSize="24sp">
</CheckBox>

2.自定义显示提示时的内容背景样式 au_textview.xml:
在这里插入图片描述

<?xml version="1.0" encoding="utf-8"?>
<!-- 自定义显示提示时的内容背景样式xml -->
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:textSize="18sp"
    android:textColor="#ff9999">
</TextView>
  1. stu_list.xml:

在这里插入图片描述

<?xml version="1.0" encoding="utf-8"?>
<!-- 自定义下拉框的样式,用于学生信息显示-->
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <TextView
        android:id="@+id/name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:text="易烊千玺"
        android:textSize="24sp"
        android:textColor="#404040"/>

    <TextView
        android:id="@+id/major"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/name"
        android:layout_marginLeft="20dp"
        android:text="物联网工程"
        android:textColor="#003472"
        android:textSize="15sp" />
    <ImageView
        android:id="@+id/edit"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:src="@drawable/edit"
        android:layout_toLeftOf="@+id/delete"
        android:layout_marginRight="5dp"
        />
    <ImageView
        android:id="@+id/delete"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:layout_alignParentRight="true"
        android:src="@drawable/delete"
        />
</RelativeLayout>

4.Drawable中 shape.xml和shape_button.xml

  • shape.xml:
<?xml version="1.0" encoding="utf-8"?>
<!-- 形状 -->
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <solid android:color="#ffffff" />
    <!-- 边框 -->
    <stroke
        android:width="1dip"
        android:color="#ffffff" />
    <!-- 内填充颜色 -->
    <padding
        android:bottom="10dp"
        android:left="10dp"
        android:right="10dp"
        android:top="10dp" />
    <!-- 圆角 -->
    <corners android:radius="6dp" />
</shape>
  • shape_button.xml
<?xml version="1.0" encoding="utf-8"?>
<!-- 形状 -->
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <solid android:color="#80ff1234" />
    <!-- 边框 -->
    <stroke
        android:width="1dip"
        android:color="#ccff1234" />
    <!-- 内填充颜色 -->
    <padding
        android:bottom="10dp"
        android:left="10dp"
        android:right="10dp"
        android:top="10dp" />
    <!-- 圆角 -->
    <corners android:radius="6dp" />
</shape>

大功告成!这是无数据库版本;SQLite数据库版本连接在这儿~
