Android (Java/Kotlin)163yt.cn
Java示例（仅活动（Activity）框架）:

java
import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// 初始化UI组件和其他逻辑
}

复制代码

}
Kotlin示例（同样仅活动框架）:
kotlin
import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
class MainActivity : AppCompatActivity() {

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
// 初始化UI组件和其他逻辑
}

复制代码

}
2. iOS (Swift/Objective-C)
Swift示例（仅视图控制器（View Controller）框架）:
swift
import UIKit
class ViewController: UIViewController {

override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}

复制代码

}
Objective-C示例（同样仅视图控制器框架）:
objc
#import <UIKit/UIKit.h>
@interface ViewController : UIViewController
@end
@implementation ViewController

(void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
}

@end
3. Flutter (Dart)
Dart示例（Flutter应用框架）:
dart
import ‘package:flutter/material.dart’;
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: ‘Flutter Demo’,
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(title: ‘Flutter Demo Home Page’),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
@override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State {
int _counter = 0;
void _incrementCounter() {
setState(() {
_counter++;
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text(
‘You have pushed the button this many times:’,
),
Text(
‘$_counter’,
style: Theme.of(context).textTheme.headline4,
),
],
),
),
floatingActionButton: FloatingActionButton(
onPressed: _incrementCounter,
tooltip: ‘Increment’,
child: Icon(Icons.add),
), // This trailing comma makes auto-formatting nicer for build methods.
);
}
}
这些代码只是起点，你可以根据需要举行扩展和修改。由于生成一个完整的App代码涉及到很多细节（如用户界面操持、后端逻辑、数据持久化等），并且差别的平台（如Android、iOS、Web等）使用差别的编程语言和框架，这里我将为你提供几种差别平台和语言的简化示例代码框架。
