Answer 1

Edittext extends Textview so you can only cast an Edittext to a Textview but not a Textview to an Edittext. But you can change the attributes of the Textview so it acts like an Edittext.

Answer 2

This is only the xml code. What error do you get exactly?

Answer 3

/androidx.constraintlayout.widget.ConstraintLayout>
///////////////////////**********************/*MainActivity.java//////////////////**********************////
package com.example.interactiveelements;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
public class MainActivity extends AppCompatActivity {
public void ClickFunction(View view){
EditText textview = (EditText) findViewById(R.id.textView);
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
}
Error
Unexpected cast to EditText: layout tag was TextView (Id bound to a text view in activtiy_main.xml)

Answer 4

But than you still need to change it to Textview in the java file, if you dont change the Textview in the XML to an Edittext

Answer 5

So what code I had to write in order to get value from the text box.
Like
Log.i(tag:"Value", textview.getText().toString();

Answer 6

You could add android: editable ="true" in the xml file.
