在这里插入图片描述

第二步：在Mainactivity.java完成功能的实现

找到ID并绑定

实现功能

首先定义1个SharedPreferences和3个String类型的数组来存放数据

RadioGroup 控件1（r1）

r1.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
              @Override           public void onCheckedChanged(RadioGroup radioGroup, int i) {
                  RadioButton radioButton= (RadioButton)radioGroup.findViewById(i);//获取数据               sharedPreferences=getSharedPreferences("date", Context.MODE_PRIVATE);               SharedPreferences.Editor editor1=sharedPreferences.edit();               editor1.putString("one",radioButton.getText().toString());//保存数据               editor1.apply();               String a=sharedPreferences.getString("one","");//得到数据               Toast.makeText(MainActivity.this,a,Toast.LENGTH_SHORT).show();//显示数据               Toast.makeText(MainActivity.this,a,Toast.LENGTH_SHORT).show();                         }       });

RadioGroup 控件2（r2）

r2.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
              @Override           public void onCheckedChanged(RadioGroup radioGroup, int i) {
                  RadioButton radioButton= (RadioButton)radioGroup.findViewById(i);//获取数据               sharedPreferences=getSharedPreferences("date", Context.MODE_PRIVATE);               SharedPreferences.Editor editor1=sharedPreferences.edit();               editor1.putString("two",radioButton.getText().toString());//保存数据               editor1.apply();               String a=sharedPreferences.getString("two","");//得到数据               Toast.makeText(MainActivity.this,a,Toast.LENGTH_SHORT).show();//显示数据           }       });

RadioGroup 控件3（r3）

r3.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
             @Override          public void onCheckedChanged(RadioGroup radioGroup, int i) {
                 RadioButton radioButton= (RadioButton)radioGroup.findViewById(i);//获取数据              sharedPreferences=getSharedPreferences("date", Context.MODE_PRIVATE);              SharedPreferences.Editor editor1=sharedPreferences.edit();              editor1.putString("three",radioButton.getText().toString());//保存数据              editor1.apply();              String a=sharedPreferences.getString("three","");//得到数据              Toast.makeText(MainActivity.this,a,Toast.LENGTH_SHORT).show();//显示数据          }      });

RadioGroup 控件4（r4）

r4.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
             @Override          public void onCheckedChanged(RadioGroup radioGroup, int i) {
                 RadioButton radioButton= (RadioButton)radioGroup.findViewById(i);//获取数据              sharedPreferences=getSharedPreferences("date", Context.MODE_PRIVATE);              SharedPreferences.Editor editor1=sharedPreferences.edit();              editor1.putString("four",radioButton.getText().toString());//保存数据              editor1.apply();              String a=sharedPreferences.getString("four","");//得到数据              Toast.makeText(MainActivity.this,a,Toast.LENGTH_SHORT).show();//显示数据          }      });

RadioGroup 控件5（r5）

r5.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
              @Override           public void onCheckedChanged(RadioGroup radioGroup, int i) {
                  RadioButton radioButton= (RadioButton)radioGroup.findViewById(i);//获取数据               sharedPreferences=getSharedPreferences("date", Context.MODE_PRIVATE);               SharedPreferences.Editor editor1=sharedPreferences.edit();               editor1.putString("five",radioButton.getText().toString());//保存数据               editor1.apply();               String a=sharedPreferences.getString("five","");//得到数据               Toast.makeText(MainActivity.this,a,Toast.LENGTH_SHORT).show();//显示数据           }       });

3个Spinner的功能
首先选择Spinner的样式，在添加监听器

Spinner控件1（s1）

OneStr=getResources().getStringArray(R.array.one);       adapter1=new ArrayAdapter(this,android.R.layout.simple_spinner_item,OneStr);//将可选的内容与ArrayAdapter连接       adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);//设置下拉列表的风格       s1.setAdapter(adapter1);       s1.setSelection(0,true);//默认选择的值

Spinner控件2（s2）

TwoStr=getResources().getStringArray(R.array.two);       adapter2=new ArrayAdapter(this,android.R.layout.simple_spinner_item,TwoStr);//将可选的内容与ArrayAdapter连接       adapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);//设置下拉列表的风格       s2.setAdapter(adapter2);       s2.setSelection(0,true);//默认选择的值

Spinner控件3（s3）

ThreeStr=getResources().getStringArray(R.array.three);       adapter3=new ArrayAdapter(this,android.R.layout.simple_spinner_item,ThreeStr);//将可选的内容与ArrayAdapter连接       adapter3.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);//设置下拉列表的风格       s3.setAdapter(adapter3);       s3.setSelection(0,true);//默认选择的值

Spinner控件监听器

在倒数第二个花括号定义3个类

private class SpinnerSelectedListener1 implements Spinner.OnItemSelectedListener   {
             }private class SpinnerSelectedListener2 implements Spinner.OnItemSelectedListener   {
             }private class SpinnerSelectedListener3 implements Spinner.OnItemSelectedListener   {
             }

鼠标移至Spinner.OnItemSelectedListener，键盘按下Alt+Enter，选择第一个，点ok

private class SpinnerSelectedListener1 implements Spinner.OnItemSelectedListener    {
           @Override        public void onItemSelected(AdapterView
    adapterView, View view, int i, long l) {
                       }        @Override        public void onNothingSelected(AdapterView
    adapterView) {
           }    }

Spinner控件监听器1

private class SpinnerSelectedListener1 implements Spinner.OnItemSelectedListener  {
         @Override      public void onItemSelected(AdapterView
    adapterView, View view, int i, long l) {
             sharedPreferences=getSharedPreferences("date",Context.MODE_PRIVATE);          SharedPreferences.Editor editor=sharedPreferences.edit();          editor.putString("first",OneStr[i]);//保存数据          editor.apply();          String a=sharedPreferences.getString("first","");//得到数据          Toast.makeText(MainActivity.this,a,Toast.LENGTH_SHORT).show();//显示数据      }      @Override      public void onNothingSelected(AdapterView
    adapterView) {
         }  }

Spinner控件监听器2

private class SpinnerSelectedListener2 implements Spinner.OnItemSelectedListener  {
         @Override      public void onItemSelected(AdapterView
    adapterView, View view, int i, long l) {
             sharedPreferences=getSharedPreferences("date",Context.MODE_PRIVATE);          SharedPreferences.Editor editor=sharedPreferences.edit();          editor.putString("second",TwoStr[i]);//保存数据          editor.apply();          String a=sharedPreferences.getString("second","");//得到数据          Toast.makeText(MainActivity.this,a,Toast.LENGTH_SHORT).show();//显示数据      }      @Override      public void onNothingSelected(AdapterView
    adapterView) {
         }  }

Spinner控件监听器3

private class SpinnerSelectedListener3 implements Spinner.OnItemSelectedListener  {
         @Override      public void onItemSelected(AdapterView
    adapterView, View view, int i, long l) {
             sharedPreferences=getSharedPreferences("date",Context.MODE_PRIVATE);          SharedPreferences.Editor editor=sharedPreferences.edit();          editor.putString("third",ThreeStr[i]);//保存数据          editor.apply();          String a=sharedPreferences.getString("third","");//得到数据          Toast.makeText(MainActivity.this,a,Toast.LENGTH_SHORT).show();//显示数据      }      @Override      public void onNothingSelected(AdapterView
    adapterView) {
         }  }

绑定监听器

按钮的监听事件并把数据传至服务器

首先进行网络请求和下载okhttp3

implementation 'com.squareup.okhttp3:okhttp:3.12.1'debugImplementation 'com.squareup.okhttp3:logging-interceptor:3.12.1'

按钮的监听事件

判断数量是否为空

success.setOnClickListener(new View.OnClickListener() {
               @Override            public void onClick(View view) {
                   if(e1.getText().toString().equals(""))                {
                       Toast.makeText(MainActivity.this,"订购失败",Toast.LENGTH_SHORT).show();                    return;                }            }        });

获取数量的数据并保存

success.setOnClickListener(new View.OnClickListener() {
               @Override            public void onClick(View view) {
                   if(e1.getText().toString().equals(""))                {
                       Toast.makeText(MainActivity.this,"订购失败",Toast.LENGTH_SHORT).show();                    return;                }                Toast.makeText(MainActivity.this,"订购成功",Toast.LENGTH_SHORT).show();                sharedPreferences=getSharedPreferences("date",Context.MODE_PRIVATE);                SharedPreferences.Editor editor=sharedPreferences.edit();                editor.putString("six",e1.getText().toString());                editor.apply();            }        });

开启子线程

success.setOnClickListener(new View.OnClickListener() {
               @Override            public void onClick(View view) {
                   if(e1.getText().toString().equals(""))                {
                       Toast.makeText(MainActivity.this,"订购失败",Toast.LENGTH_SHORT).show();                    return;                }                Toast.makeText(MainActivity.this,"订购成功",Toast.LENGTH_SHORT).show();                sharedPreferences=getSharedPreferences("date",Context.MODE_PRIVATE);                SharedPreferences.Editor editor=sharedPreferences.edit();                editor.putString("six",e1.getText().toString());                editor.apply();                new Thread(new Runnable() {
                       @Override                    public void run() {
                           try {
                           runOnUiThread(new Runnable() {
                                   @Override                                public void run() {
                                       Toast.makeText(MainActivity.this,"网络连接成功",Toast.LENGTH_SHORT).show();                                }                            });                        }                        catch (Exception e)                        {
                               e.printStackTrace();                            runOnUiThread(new Runnable() {
                                   @Override                                public void run() {
                                       Toast.makeText(MainActivity.this,"网络连接失败",Toast.LENGTH_SHORT).show();                                }                            });                        }                    }                }).start();            }        });

获取全部的数据

String sr1=sharedPreferences.getString("r1","");                            String sr2=sharedPreferences.getString("r2","");                            String sr3=sharedPreferences.getString("r3","");                            String sr4=sharedPreferences.getString("r4","");                            String sr5=sharedPreferences.getString("r5","");                            String sr6=sharedPreferences.getString("dd","");                            String sr7=sharedPreferences.getString("rqi","");                            String sr8=sharedPreferences.getString("xt","");                            String sr9=sharedPreferences.getString("pl","");                            String json="{\n" +                                    "    \"car\":\""+sr1+"\",\n" +                                    "    \"time\":\""+sr7+"\",\n" +                                    "    \"number\":\""+sr6+"\",\n" +                                    "    \"pail\":\""+sr9+"\",\n" +                                    "    \"bsx\":\""+sr2+"\",\n" +                                    "    \"lg\":\""+sr3+"\",\n" +                                    "    \"zk\":\""+sr4+"\",\n" +                                    "    \"sc\":\""+sr5+"\",\n" +                                    "    \"xg\":\""+sr8+"\"\n" +                                    "}";                            System.out.println(json);

数据上传服务器

success.setOnClickListener(new View.OnClickListener() {
               @Override            public void onClick(View view) {
                   if(e1.getText().toString().equals(""))                {
                       Toast.makeText(MainActivity.this,"订购失败",Toast.LENGTH_SHORT).show();                    return;                }                Toast.makeText(MainActivity.this,"订购成功",Toast.LENGTH_SHORT).show();                sharedPreferences=getSharedPreferences("date",Context.MODE_PRIVATE);                SharedPreferences.Editor editor=sharedPreferences.edit();                editor.putString("six",e1.getText().toString());                editor.apply();                new Thread(new Runnable() {
