不断出现错误 "Conflicting declarations: val open: ImageButton, val open: ImageButton"

Question

我仍在创建我的应用程序。我正试图让它到达我单击 imabe 按钮时它将转到新 activity 的位置。每个图像按钮都在 activity.

上

代码*

`

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main);


    val open: ImageButton = findViewById<ImageButton>(R.id.card1)
    open.setOnClickListener(View.OnClickListener {
        val intent = Intent(this@MainActivity, TMs::class.java)
        startActivity(intent)
    })

    val open: ImageButton = findViewById<ImageButton>(R.id.card2)
    open.setOnClickListener(View.OnClickListener {
        val intent = Intent(this@MainActivity, Schematics::class.java)
        startActivity(intent)
    })

    val open: ImageButton = findViewById<ImageButton>(R.id.card3)
    open.setOnClickListener(View.OnClickListener {
        val intent = Intent(this@MainActivity, PartsCheatSheets::class.java)
        startActivity(intent)
    })

    val open: ImageButton = findViewById<ImageButton>(R.id.card4)
    open.setOnClickListener(View.OnClickListener {
        val intent = Intent(this@MainActivity, GeneratorLoadWiring::class.java)
        startActivity(intent)
    })

    val open: ImageButton =findViewById<ImageButton>(R.id.card5)
    open.setOnClickListener(View.OnClickListener {
        val intent = Intent(this@MainActivity, Hdt::class.java)
        startActivity(intent)
    })

    val open: ImageButton =findViewById<ImageButton>(R.id.card6)
    open.setOnClickListener(View.OnClickListener {
        val intent = Intent(this@MainActivity, GCP::class.java)
        startActivity(intent)
    })

    val open: ImageButton =findViewById<ImageButton>(R.id.card7)
    open.setOnClickListener(View.OnClickListener {
        val intent = Intent(this@MainActivity, SP::class.java)
        startActivity(intent)
    })

    val open: ImageButton =findViewById<ImageButton>(R.id.card8)
    open.setOnClickListener(View.OnClickListener {
        val intent = Intent(this@MainActivity, Cummins::class.java)
        startActivity(intent)
    })

}

}`

当它像这样设置时它可以工作，但只有当我点击第一个然后转到第二个时，依此类推列表。

代码*

`

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main);


    val open: ImageButton = findViewById<ImageButton>(R.id.card1)

                        startActivity(intent)

                        val open: ImageButton =findViewById<ImageButton>(R.id.card6)

                                startActivity(intent)

                                val open: ImageButton =findViewById<ImageButton>(R.id.card8)
                                open.setOnClickListener(View.OnClickListener {
                                    val intent = Intent(this@MainActivity,Cummins::class.java)
                                    startActivity(intent)
                                })
                            })
                        })
                    })
                })
            })
        })
    })

}

Answer 1

变化：

val open: ImageButton = findViewById<ImageButton>(R.id.card1)
open.setOnClickListener(View.OnClickListener {
    val intent = Intent(this@MainActivity, TMs::class.java)
    startActivity(intent)
})

收件人：

val card1: ImageButton = findViewById<ImageButton>(R.id.card1)
card1.setOnClickListener(View.OnClickListener {
    val intent = Intent(this@MainActivity, TMs::class.java)
    startActivity(intent)
})

对其他按钮也这样做
