Android studio 学生信息录入表（课堂作业）

任务：

制作学生信息录入表：

开发步骤：

• 运用线性布局嵌套，按照模型制作activity_main.xml
• 添加组件TextView、EditText、单选框、复选框、按钮等
• 编辑MainActivity.java，制作各组件监听器

源代码：

activity_main.xml

 

 

MainActivity.java

package com.example.excel;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.TextView;
import android.widget.EditText;
import android.widget.RadioButton;

public class MainActivity extends AppCompatActivity {

    Button okBtn;
    EditText editname,editage;
    TextView showmesage;
    RadioButton r1,r2;
    CheckBox c1,c2,c3;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        editname = (EditText)findViewById(R.id.name);
        editage = (EditText)findViewById(R.id.age);
        okBtn = (Button)findViewById(R.id.confirm);
        showmesage = (TextView)findViewById(R.id.message);
        r1 = (RadioButton)findViewById(R.id.man);
        r2 = (RadioButton)findViewById(R.id.woman);
        c1 = (CheckBox)findViewById(R.id.basketball);
        c2 = (CheckBox)findViewById(R.id.football);
        c3 = (CheckBox)findViewById(R.id.music);
        okBtn.setOnClickListener(new mClick());
    }

    class mClick implements OnClickListener{
        public void onClick(View v){
            CharSequence xingming = "",xingbie = "",nianling = "",aihao = "";
            xingming = editname.getText();
            if(r1.isChecked())
                xingbie = r1.getText();
            if(r2.isChecked())
                xingbie = r2.getText();
            nianling = editage.getText();
            if(c1.isChecked())
                aihao = aihao+" "+c1.getText();
            if(c2.isChecked())
                aihao = aihao+" "+c2.getText();
            if(c3.isChecked())
                aihao = aihao+" "+c3.getText();
            showmesage.setText("姓名："+xingming+"\n性别："+xingbie+"\n年龄："+nianling+"\n业余爱好："+aihao);
        }
    }
}

运行结果：
