如何从底页导航到 activity

Question

我在我的应用程序中实现了一个 bottomsheet。我使用 inflater 来显示 bottomsheet 对话框，这是我在 NewSignUpActivity 中显示 bottomsheet 对话框的代码。

class NewSignUpActivity : AppCompatActivity() {

    private lateinit var btnBottomSheet: RelativeLayout

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

        btnBottomSheet = findViewById(R.id.riderBtn)
        val bottomSheetCallback = object : BottomSheetBehavior.BottomSheetCallback(){
            override fun onStateChanged(bottomSheet: View, newState: Int) {}
            override fun onSlide(bottomSheet: View, slideOffset: Float) {}
        }
        val bottomSheetView = layoutInflater.inflate(R.layout.layout_bottom_sheet, null)
        val bottomSheetDialog = BottomSheetDialog(this)
        bottomSheetDialog.setContentView(bottomSheetView)
        val bottomSheetBehavior = BottomSheetBehavior.from(bottomSheetView.parent as View)
        bottomSheetBehavior.setBottomSheetCallback(bottomSheetCallback)

        btnBottomSheet.setOnClickListener {
            bottomSheetBehavior.state = BottomSheetBehavior.STATE_EXPANDED
            bottomSheetDialog.show()
        }


    }
}

这是它在视图中的样子。

如您所见，底页上有一个按钮我想导航到另一个布局 activity 单击是按钮后，我该怎么做？我对使用 Kotlin android 开发还很陌生。

已编辑：为 bottomsheet 对话框添加了我的 XML 文件，请参阅 below._ 文件名是 layout_bottom_sheet.xml

Answer 1

BottomSheetView 布局已经膨胀：

val bottomSheetView = layoutInflater.inflate(R.layout.layout_bottom_sheet, null)

并且此布局包含“是”按钮，因此您可以只使用 findViewById()。假设YES按钮的id为btn_yes:

val btnYes = bottomSheetView.findViewById<Button>(R.id.btn_yes)

btnYes.setOnClickListener {
    startActivity(myIntent) // Add your activity intent
}

更新：

因为你提供的是yellowBtn按钮的id，所以你可以使用它：

val btnYes = bottomSheetView.findViewById<Button>(R.id.yellowBtn)
btnYes.setOnClickListener {
    startActivity(myIntent) // Add your activity intent
}
