EditText setText () sets text in multiple EditText views

I encounter strange behavior, I suspect a mistake, but maybe I'm missing something. Code snippets at the end of the message. I can also publish .xml, but I don't think it is necessary to understand the problem.

I have a horizontal line layout that I add TableLayouts depending on the number of players.

Table layouts contain several fields: TextView, EditText, Buttons, etc.

When I initialize each TableLayout, I add it to LinearLayout (via xml inflation) and then initialize the fields.

The fact is that EditText fields are always updated with the information of the latest players. From what I can tell, my setText call is passed to each EditText.

I find EditText using findViewById in the parent TableLayout (in fact, grandpa and grandma, since there is a TableRow.

The EditText identifier is not unique throughout the tree, but unique in terms of table layout.

Possible reasons: 1) I get the wrong kind of EditText when I find ById: This may not be the case. I changed my code to publish the objectID for the EditTextView, I get IN A TEXTVIEW and get the unique identifiers of the objects. By sending the same myEditText.toString () to EditText, I get the duplicate value of the last identifier of the object. Repeat using the same findView logic when the field is a TextView and displays the "multiple" behavior of setText whenever it is EditText.

CODE SNIPPETS:

onCreate Intialization Code:

TableLayout tl = (TableLayout)inflater.inflate(R.layout.playerpanel, llayout, false);
InitializePlayer(player1,tl);
llayout.addView(tl);

- - :

public void InitializePlayer(Player p, TableLayout tl)
{
    players.add(p);
    tl.setTag(p);
    //INITIALIZE LISTENERS HERE - SNIPPED FOR READABILITY

    TextView scoreLabel = (TextView)tl.findViewById(R.id.currentScore);
    EditText curPoints = (EditText)tl.findViewById(R.id.scoreEntry);
    curPoints.setText(p.getScore());


    EditText playerEntry = (EditText)tl.findViewById(R.id.playerName);
    playerEntry.setText(tl.toString());

    //CONFIRMING UNIQUE OBJECTS HERE should actually be p.getScore()
    scoreLabel.setText(playerEntry.toString());
    ListView lv = (ListView)tl.findViewById(R.id.listView);
    lv.setAdapter(new ArrayAdapter<String>(this,R.layout.list_item, p.getTurns() ));

OnClickCode, :

private OnClickListener addButtonListener = new OnClickListener() {
    public void onClick(View v) {
      // get all the objects I care about
        TableRow tr = (TableRow)v.getParent();
        TableLayout tl = (TableLayout)tr.getParent();
        EditText ev = (EditText)tl.findViewById(R.id.scoreEntry);
        Player pl = (Player)tl.getTag();

        TextView scoreLabel = (TextView)tl.findViewById(R.id.currentScore);

        pl.addScore(ev.getText().toString());
        scoreLabel.setText(pl.getScore());
        ListView lv = (ListView)tl.findViewById(R.id.listView);
        ArrayAdapter aa = (ArrayAdapter)lv.getAdapter();
        aa.notifyDataSetChanged();
        InputMethodManager imm = (InputMethodManager)v.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(v.getWindowToken(), 0);

        EditText playerEntry = (EditText)tl.findViewById(R.id.playerName);
        playerEntry.setText(playerEntry.toString());
