// 导入必要的类
import android.content.Intent
import android.os.Bundle
import android.view.View
import androidx.appcompat.app.AppCompatActivity

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
    }

    // 按钮1的点击事件
    fun openActivity1(view: View) {
        val intent = Intent(this, Activity1::class.java)
        startActivity(intent)
    }

    // 按钮2的点击事件
    fun openActivity2(view: View) {
        val intent = Intent(this, Activity2::class.java)
        startActivity(intent)
    }

    // 按钮3的点击事件
    fun openActivity3(view: View) {
        val intent = Intent(this, Activity3::class.java)
        startActivity(intent)
