final TextView textViewPrint;
  
Button btn_print;

final EditText editTextType;
     
final CheckBox checkbox;


        textViewPrint = findViewById(R.id.print_text);
        btn_print =findViewById(R.id.button_add);
         editTextType = findViewById(R.id.test_textEdit);
        checkbox = findViewById(R.id.checkBox);


        
         btn_print.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                textViewPrint.setText(editTextType.getText().toString()) ;

checkbox = findViewById(R.id.checkBox);

If this is returning a non-null value, then I assume you already have a Checkbox widget on the layout. if so, then what exactly are you wanting to do with the checkbox?

I want to create a checkbox onClick so when the button is clicked I want it to create a checkbox.

Have you tried something like:

Checkbox cb = new Checkbox();
cb.setId(###); // optional

If you want to display it, you'll also need to add it to a view.

Just out of curiosity, why create this control at runtime rather than in the layout file?

I want to make a to-do list so when a user type for example play piano in the editText my app Will add play piano and a checkbox that they can press to finish it. Im also having problems beeing able to add more than 1 task. My text need beeing overwritten by the last one. For example if i wrote play piano and added it then go the gym. The gym one would overwrite the last one. I’m not at a computer right now I am going to try if it works tomorrow thanks alot

You need to put a ListView in the main layout. Create a "row" layout for each row in that ListView. In this row layout, put a CheckBox control and a TextView control. Create a custom adapter for it (e.g., derived from ArrayAdapter). In the adapter's getView() method, inflate the row layout, and then assign values to the checkbox and text controls. In the button's onClick() handler, simply add a new item to the custom adapter, then call the adapter's notifyDataSetChanged() method for it to show up in the list.

This is a VERY common thing to do, so more detailed examples are plentiful on the 'net.

Solution 1

LinearLayout l1 = (LinearLayout)findViewById(R.id.linearlayout);
btn_print.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
          CheckBox checkbox = new CheckBox(this);
        checkbox.setId(0);

        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.WRAP_CONTENT);

        l1.addView(checkbox,params);
    }
});

Hello thanks for the answer. I have a question I can't seem to get it to work. I don't have an id of linearlayout and wanted to ask from what element should I pick the id from?

You can change the checkbox id in programming throw and this id is a not presenting the all program and you can access the below method
CheckBox c1 = (CheckBox)findViewById(0);
c1.getText();//This method to access the data of dynamically data access bro
