Save input text and use same text as checkbox label in another activity

Question

In my android app, I want to provide a text box to input a name and save it. Later I want to retrieve the text as checkbox label in other activity. So.. how can I do it? Like multiple names will generate multiple checkbox in next activity..

Thank you in advance..

You can store such data in SharedPreferences, see this guide:

https://developer.android.com/training/data-storage/shared-preferences.html

So in your case:

1) Get data from EditText:

EditText etTextInput = findViewById(R.id.my_edittext);
String text = etTextInput.getText().toString();

2) Write to Shared Preferences:

Context context = getActivity();
SharedPreferences sharedPref = context.getSharedPreferences(
        "preference_file_key", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putString("key_my_text", text);
editor.commit();

3) Retrieve from Shared Preferences in another Activity:

SharedPreferences sharedPref = context.getSharedPreferences(
            "preference_file_key", Context.MODE_PRIVATE);
String text = sharedPref.getString("key_my_text", "default_value");

4) Set text to your CheckBox:

CheckBox checkbox = findViewById(R.id.my_ checkbox);
checkbox.setText(text);

Note this is very simplified, you can i.e. create a Shared Preferences helper class as per this question and answers: SharedPreferences helper class
