家庭记账本app进度之复选框以及相应滚动条的应用

这次主要是对于android中复选框的相应的操作。以及其中可能应用到的滚动条的相关应用。每一个复选框按钮都要有一个checkBox与之相对应。

推荐使用XML配置,基本语法如下:
<CheckBox
    android:text="显示文本"
    android:id="@+id/ID号"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
</CheckBox>
最后添加点击事件实现相应的操作。具体的代码实现如下:

MainActivity.java

package com.example.myapplicationhome;
import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.CheckBox;

public class MainActivity extends AppCompatActivity {

    private CheckBox mChkBoxwen1,mChkBoxwen2,mChkBoxwen3,mChkBoxwen4,mChkBoxwen5,mChkBoxwen6;

    private TextView mTxtHobby;
    @Override
