android - setTextAppearance deprecated in API level 23

Question

public void setTextAppearance (Context context, int resId) Added in API level 1
This method was deprecated in API level 23. Use setTextAppearance(int) instead.

My Question: Why it's been deprecated? Why it doesn't need Context anymore? And most importantly, how to use setTextAppearance(int resId) for older versions?

Answer 1

You can use TextViewCompat from the support/androidX library:

    import android.support.v4.widget.TextViewCompat // for support-library
    import androidx.core.widget.TextViewCompat      // for androidX library

    // ...

    TextViewCompat.setTextAppearance(view, resId)

Internally it gets the context from the view (view.getContext()) on API < 23.
