Apps Checkbox to show/hide textview

[little_star]

Hi,
I am trying to create a small app as part of my learning experience in Android.
I got this code to show and hide a text using a checkbox
How can I control 2 different text with one checkbox (show one text and hide another and vice-versa)
Can someone please help me to make this work

Import ...
public class MainActivity extends AppCompatActivity {

    private TextView txtHelloWorld;

   @Override
    protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);
       CheckBox checkBoxVisibility = findViewById(R.id.checkBox_visibility);
       txtHelloWorld = findViewById(R.id.txtHelloWorld);
       boolean isChecked = checkBoxVisibility.isChecked();
       updateTextVisibility(isChecked);
       checkBoxVisibility.setOnClickListener(v -> {

           boolean isChecked1 = ((CheckBox)v).isChecked();
           updateTextVisibility(isChecked1);
       });
   }
    private void updateTextVisibility(boolean isChecked) {
        if (isChecked) {
            txtHelloWorld.setVisibility(View.VISIBLE);
        } else {
            txtHelloWorld.setVisibility(View.INVISIBLE);
        }
    }
}

Hi little_star,

1) If you need to create one or more texts to show/hide, you will need a corresponding number of TextViews

private TextView txtHelloWorld, txtAnotherText;

2) Now you need the corresponding layout references

txtHelloWorld = findViewById(R.id.txtHelloWorld);
txtAnotherText= findViewById(R.id.txtAnotherText);

3) Now what you want to achieve is that when the first text appears, the second text disappears, using a checkbox as a trigger.
You already have the function, so just add the case you need.

1. private void updateTextVisibility(boolean isChecked) // When checking the trigger (checkbox)
2. {
3. if (isChecked)
4. {
5. txtHelloWorld.setVisibility(View.VISIBLE); // The first is visibile
6. txtAnotherText.setVisibility(View.INVISIBLE); // and the second is invisible
   
7. }
8. else
9. {
10. txtHelloWorld.setVisibility(View.INVISIBLE);
11. txtAnotherText.setVisibility(View.VISIBLE);
12. }
13. }

I hope I was able to help you, bye
