本文实例为大家分享了Android简单实现天气预报App的具体代码，供大家参考，具体内容如下
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"

</androidx.constraintlayout.widget.ConstraintLayout>
效果：

效果:
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("");
}
}
});
}
2.展示页面
代码如下（示例）：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_show);
getSupportActionBar().hide();
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);
TextView wind=findViewById(R.id.textView5);
TextView aqi=findViewById(R.id.textView6);
TextView weather=findViewById(R.id.textView4);
TextView ziwaixian=findViewById(R.id.textView16);
TextView t2=findViewById(R.id.weathertoday);
TextView t3=findViewById(R.id.temtoday);
TextView t4=findViewById(R.id.qualtoday);
TextView m2=findViewById(R.id.weathertomo);
TextView m3=findViewById(R.id.temtomo);
TextView m4=findViewById(R.id.qualtomo);
Intent intent=getIntent();
String address=getIntent().getStringExtra("address");
textView.setText(address);
//c5494be085dd41dca6ec4ffa59c9ed6a
String code="APPCODE "+"c5494be085dd41dca6ec4ffa59c9ed6a";
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+"℃");
t4.setText(weatherResult.showapi_res_body.f1.jiangshui);
m2.setText(weatherResult.showapi_res_body.f2.day_weather);
m3.setText(weatherResult.showapi_res_body.f2.day_air_temperature+"/"+weatherResult.showapi_res_body.f2.night_air_temperature+"℃");
m4.setText(weatherResult.showapi_res_body.f2.jiangshui);
tem.setText(weatherResult.showapi_res_body.now.temperature+"℃");
weather.setText(weatherResult.showapi_res_body.now.weather);
wind.setText(weatherResult.showapi_res_body.now.wind_direction+weatherResult.showapi_res_body.now.wind_power+" "+weatherResult.showapi_res_body.now.sd);
aqi.setText("aqi:"+weatherResult.showapi_res_body.now.aqi);
ziwaixian.setText("紫外线强度："+weatherResult.showapi_res_body.f1.ziwaixian);
}
@Override
public void onFailure(Call<WeatherResult> call, Throwable t) {
}
});
}
