生成一段Android 天气预报APP的代码

你好，以下是一段Android天气预报APP的代码：

public class MainActivity extends AppCompatActivity {

    private TextView mCityTextView;
    private TextView mWeatherTextView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mCityTextView = findViewById(R.id.city_text_view);
        mWeatherTextView = findViewById(R.id.weather_text_view);

        String city = "北京";
        String weather = "晴";

        mCityTextView.setText(city);
        mWeatherTextView.setText(weather);
    }
}

以上代码仅供参考，具体实现还需要根据实际需求进行修改。希望对你有所帮助。
