How can I access a TextView declared in XML within my Fragment?-CodePudding

Here is the kotlin file of the fragment:

override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle? ): View? {
    
        val view = inflater.inflate(R.layout.fragment_blank, container, false)
    
        view.textView1 <- Here is the problem
    
        return view
    }

Down here is xml file of the fragment. I hope it's all right...

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/purple_200"
    tools:context=".BlankFragment">

    <TextView
        android:id="@ id/textView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="1"
        android:gravity="center"
        android:textSize="80sp" />
</FrameLayout>

CodePudding user response：

textView = findViewById(R.id.yourId);

and next you can use it

CodePudding user response：

Actually findViewById() is not available on the Fragment class.

However, you can use inflated view to access the findViewById() as shown on this example.

class MyFragment : Fragment() {

    lateinit var textView: TextView

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        // Inflate the layout for this fragment
        val view = inflater.inflate(R.layout.fragment_my, container, false)
        
        //use view to access findViewById() method
        textView = view.findViewById(R.id.textView1)
        textView.text = "Test 1"
        return view
    }
}

That said the recommended way would be to use Databinding or View Binding
