标题与自定义工具栏中的视图重叠

Question

大家好，我想在我的自定义工具栏中设置标题。直到我通过XML显式才能工作。我不想在工具栏中放入XML中的文本视图。我尝试了此 post 并尝试通过代码设置，它行不通。

咨询。xml

我尝试了代码

toolbaractivity.kt

class ToolbarActivity : AppCompatActivity() {

    private lateinit var binding: ToolBarLayoutBinding

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = ToolBarLayoutBinding.inflate(layoutInflater)
        setContentView(binding.root)
        actionBar()
        setupSearchView()
    }

    private fun actionBar() {
        setSupportActionBar(binding.toolbar)
        supportActionBar?.setDisplayHomeAsUpEnabled(true)
        supportActionBar?.setDisplayShowTitleEnabled(true)
        supportActionBar?.title = "Toolbar"
    }

    private fun setupSearchView() {
        var originalMargin = 0
        binding.consultationSearchView.apply {
            setOnQueryTextListener(object : SearchView.OnQueryTextListener {
                override fun onQueryTextSubmit(query: String?) = false
                override fun onQueryTextChange(newText: String?): Boolean {
                    if (newText != null) {
                    }
                    return true
                }
            })
            val params =
                binding.consultationSearchView.layoutParams as CollapsingToolbarLayout.LayoutParams
            originalMargin = params.marginStart
            setOnQueryTextFocusChangeListener { view, hasFocus ->
                binding.appBar.setExpanded(!hasFocus)
                isSelected = hasFocus
                if (hasFocus) {
                    params.marginStart = originalMargin + 150 // arbitrary constant
                } else {
                    params.marginStart = originalMargin
                }
                view.layoutParams = params
            }
        }
    }

}

看起来像

注意我不想使用XML在工具栏内设置文本视图。我想编程。在我的 github project 我使用xml文本视图。

预期输出

当屏幕打开时，我想要这样的箭头 + title

当崩溃时，它看起来像
