package com.example.safetyofficer.view

import android.content.Context
import android.util.AttributeSet
import android.widget.TextView
import androidx.appcompat.widget.Toolbar
import com.example.safetyofficer.R


class CustomToolbar @JvmOverloads constructor(
    context: Context,
    attrs: AttributeSet? = null,
    defStyleAttr: Int = R.attr.toolbarStyle
) :
    Toolbar(context, attrs, defStyleAttr) {
    private val titleView: TextView = TextView(getContext())

    override fun onLayout(changed: Boolean, l: Int, t: Int, r: Int, b: Int) {
        super.onLayout(changed, l, t, r, b)
        titleView.x = (width - titleView.width) / 2.toFloat()
    }

    override fun setTitle(title: CharSequence) {
        titleView.text = title
    }

    init {
        val textAppearanceStyleResId: Int
        val a = context.theme.obtainStyledAttributes(
            attrs,
            intArrayOf(R.attr.titleTextAppearance),
            defStyleAttr,
            0
        )
        textAppearanceStyleResId = try {
            a.getResourceId(0, 0)
        } finally {
            a.recycle()
        }
        if (textAppearanceStyleResId > 0) {
            titleView.setTextAppearance(textAppearanceStyleResId)
        }
        addView(titleView, LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT))
    }
}
