Android - Loop to collect all editText values

I have around 50 EditText fields and I want to get their values using a loop. Getting the values individually as below works fine:

    SharedPreferences settings = getSharedPreferences(filename, 0);
    SharedPreferences.Editor editor = settings.edit();
    editor.clear(); //not sure if this is required

    final EditText t1 = (EditText) findViewById(R.id.text1Value);
    String T1 = t1.getText().toString();
    editor.putstring("text1",T1);

    final EditText t2 = (EditText) findViewById(R.id.text2Value);
    String T2 = t2.getText().toString();
    editor.putstring("text2", T2);

   ................................ and so on till EditText t50.

I have tried achieving this through the loop below but couldn't get it to work.

       for(int x=1; x<50; x++) 
    {
        EditText et[x] = (EditText) findViewById(R.id.text[x]Value);
        String t[x] = et[x].getText().toString();
        String Ref = "text" + x;
        editor.putString(Ref, t[x]);
    }

int[] ids = new int[]{R.id.text1Value,R.id.text2Value,R.id.text3Value};//and so on

int i =1;
for(int id : ids){
    EditText t = (EditText) findViewById(id);
    String Ref = "text" + i;
    editor.putString(Ref, t.getText().toString());
  i++;
}

private void clearScreen() {
    int[] _ids = null;

    _ids = new int[]{R.id.etIdTAtividade, R.id.etNomeTAtividade, R.id.etNmAtividade};

    for (int i = 0; i < (_ids.length); i++) {
        EditText t = (EditText) findViewById(_ids[i]);
        t.setText("");
    }
}

If I assume you have all of these EditTexts inside a Layout called ll (should work for structures other than Layout too, such as a ViewGroup etc.):

ArrayList<String> values = new ArrayList<String>();
for (int i = 0; i < ll.getChildCount(); i++) {
    if (ll.getChildAt(i) instanceof EditText) {
        EditText et = (EditText)ll.getChildAt(i);
        values.add(et.getText().toString());
    }
}

My Android is a little rusty so apologies if there is something wrong with that, but should give you the general idea anyway

You can try this by creating an array of the ids of the textview and looping through the array. Try this:

int[] ids = new int[]{R.id.text1Value,R.id.text2Value,R.id.text3Value};//and so on

int i =1;
for(int id : ids){
    EditText t = (EditText) findViewById(id);
    String Ref = "text" + i;
    editor.putString(Ref, t.getText().toString());
  i++;
}
