TextView lost after onPause()

Question

I'm learning how to add elements to LayoutParam . I add a TextView element after each click to ```LayoutParam``.

public void send(View v){
        message=edt.getText().toString().trim();
        if(!message.equals("")){
            TextView txt = new TextView(this);
            txt.setText("You: "+message);
            txt.setPadding(10,10,10,10);
            txt.setTextSize(20);
            txt.setTextColor(Color.WHITE);
            txt.setFreezesText(true);
            llayout.addView(txt);
            scroll.fullScroll(View.FOCUS_DOWN);
            edt.setText("");
        }
    }
    

my problem is when i press the Home Button and i open the app again, i don't see any elements. as they have never been.

Answer 1

Are you recalling the send() method in the onResume() method? if not then the data you had will be lost once the activity/fragment resumes. You would need something like this inside onResume():

@Override
public void onResume(){
    super.onResume();
    send(new View());
}

The parameters inside send, will be whatever view you're passing in.
