“You need to use a Theme.AppCompat theme (or descendant) with the design library” error

Question

I\'m getting \"You need to use a Theme.AppCompat theme (or descendant) with the design library\" error every time even if I\'m obviously using an AppCompat Theme (a descenda

Answer 1

Create a ContextThemeWrapper to wrap the Service's Context with your custom theme, and get the LayoutInflater from that.

ContextThemeWrapper ctx = new ContextThemeWrapper(this, R.style.TranslucentAppTheme);
tooltipContainer = (CoordinatorLayout) LayoutInflater.from(ctx)
    .inflate(R.layout.tooltip_layout, null);

The ContextThemeWrapper modifies the given Context's theme with the one you specify in the constructor. Since a Service doesn't really have a theme, it just tacks yours onto the Service's Context, then the LayoutInflater has the appropriate theme to inflate the design Views.

Answer 2

Also receive such error in logcat:

"E/ThemeUtils: View class TableCircleCustomView is an AppCompat widget that can only be used with a Theme.AppCompat theme (or descendant)."

My app theme is "Theme.AppCompat.Light.NoActionBar"

Here is my custom view class:

class TableCircleCustomView @JvmOverloads constructor(
    context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0
) : AppCompatTextView(context, attrs, defStyleAttr) {
    ....
}

Then in Fragment i'm adding this object to RelativeLayout like so

val viewItem = TableCircleCustomView(context)     
with(RelativeLayout.LayoutParams(objectWidth, objectHeight)) {
  leftMargin = objectPosX
  topMargin = objectPosY
    
  binding.restaurantMap.addView(viewItem, this);
}

Can somebody help to solve it. Have no idea for what element i should set theme and how ((
