一、UI设计

首页UI

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/week10_3"
    tools:context=".MainActivity">

    <TextView
        android:id="@+id/text1"
        android:layout_width="133dp"
        android:layout_height="81dp"
        android:text="确定"
        android:textSize="30dp"
        android:fontFamily="sans-serif-black"
        android:gravity="center"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <EditText
        android:id="@+id/address"
        android:layout_width="214dp"
        android:layout_height="98dp"
        android:layout_marginTop="180dp"
        android:ems="10"
        android:inputType="textPersonName"
        android:text="请选择城市"
        android:gravity="center"
        android:textSize="30dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.497"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

效果:

二、调用数据并上传至前台

这里我将首页设置一个输入框，里面输入地点，然后将地点的值传给展示页面，让展示页面接收到地点后再连接对应的API并调用数据。

1.首页

代码如下（示例）：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        getSupportActionBar().hide();
        ImmersionBar.with(this)
                //.statusBarColor(R.color.purple_200)     //不写默认透明
                .init();

        TextView textView=findViewById(R.id.text1);
        EditText editText=findViewById(R.id.address);

        textView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String address=editText.getText().toString();
                Intent intent=new Intent(MainActivity.this,ShowActivity.class);
                intent.putExtra("address",address);
                startActivity(intent);

            }
        });
        editText.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if(editText.getText().toString()!=null){
                    editText.setText("");
                }
            }
        });


    }

        ImmersionBar.with(this)
                //.statusBarColor(R.color.purple_200)     //不写默认透明
                .init();

        TextView textView=findViewById(R.id.textView);
        TextView tem=findViewById(R.id.textView3);

        String address=getIntent().getStringExtra("address");
        textView.setText(address);

        Api api=RetrofitUtils.getRetrofit("https://ali-weather.showapi.com/").create(Api.class);
        Call<WeatherResult> weatherResultCall=api.getWeather(code,address);
        weatherResultCall.enqueue(new Callback<WeatherResult>() {
            @Override
            public void onResponse(Call<WeatherResult> call, Response<WeatherResult> response) {
                WeatherResult weatherResult = response.body();

                t2.setText(weatherResult.showapi_res_body.f1.day_weather);
                t3.setText(weatherResult.showapi_res_body.f1.day_air_temperature+"/"+weatherResult.showapi_res_body.f1.night_air_temperature+"℃");

            }
            @Override
