[FIXED] How get a component by programmely added id in Java for Android

Issue

I have a problem with ids on Java for Android. I do some TextView by code, and give it an id. But I can't get the TextView with the id I gave it.

I tried to do this, but it's wont work.

LinearLayout ll;
int id = 2000000;
private void init() {
    ll = findViewById(R.id.layout);
}
private TextView addTV(int x, int y, int width, int height) {
    TextView tv = new TextView(this);
    tv.setId(id);
    id++;
    tv.setText("Hello");
    return tv;
}
private void changeTextTV(int id, String text) {
    TextView tv = findViewById(id); //<- this is wrong, but I don't know what is right
    tv.setText(text);
}
init();
ll.addView(addTV(0,0,100,100));
changeTextTV(2000000, "It's me");

Could you help me ?

PS : I'm French, so sorry for my spelling mistakes

Solution

after long time search and do more test. I find some answer, you have 2 choise to get the component by a setted ID :

if you want by a hard ID :

@SuppressLint("ResourceType")
private void changeTextTV(String text) {
    TextView tv = findViewById(2000000);
    tv.setText(text);
}

or by a variable

private void changeTextTV(int id, String text) {
    TextView tv = findViewById(id);
    tv.setText(text);
}

Thanks for the time you spend for me.
