"setView should have been called" - custom class extension button

So, I have a grid of 12 x 9 “buttons” called a “tile”. Tile.java extends the Button widget.

I have a problem now, although I'm trying to get the button to display a toast that resembles the id of the button pressed.

The mesh is added dynamically, and I want it to stay that way.

Here is the code from GameBoardActivity.java:

This makes a 12x9 grid of tiles and adds a listener for each.

    public void gridRowButtons(int iterations){
    final Tile[] gridSpaces = new Tile[12];
    LinearLayout.LayoutParams buttonParams = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT, 1.0f);
    for (int i = 0; i < 12; i++) {
        String idString = String.valueOf(aToI[iterations]) + String.valueOf(i + 1);
        final int id = getResources().getIdentifier(idString, "id", getPackageName());
        gridSpaces[i] = new Tile(getApplicationContext());
        gridSpaces[i].setText("");
        gridSpaces[i].setHeight(40);
        gridSpaces[i].setWidth(40);
        gridSpaces[i].setLayoutParams(buttonParams);
        gridSpaces[i].setId(id);
        OnClickListener showID = new OnClickListener(){
            public void onClick(View view){                 
                TextView text = (TextView) findViewById(R.id.tileIDText);
                String tileID = getApplicationContext().getResources().getResourceEntryName(id);
                text.setText(tileID);
                Tile clickedTile = (Tile) findViewById(id);
                clickedTile.tileClick(0, tileID);
            }
        };
        gridSpaces[i].setOnClickListener(showID);
    }
    LinearLayout buttonRow = new LinearLayout(getApplicationContext());
    buttonRow.setOrientation(LinearLayout.HORIZONTAL);
    buttonRow.setLayoutParams(buttonParams);
    LinearLayout boardSpace = (LinearLayout) this.findViewById(R.id.boardLayout);
    for (int i = 0; i < gridSpaces.length; i++) {
        buttonRow.addView(gridSpaces[i]);
    }
    boardSpace.addView(buttonRow);
}

And here is the tileClick method mentioned above:

    public void tileClick(int action, String tileID) {
    switch(action) {
        case 1 :
            //action 1
        case 2 :
            //action 2
        default :
            Context context = getContext();
            Toast toast = new Toast(context);
            Toast.makeText(context, tileID, Toast.LENGTH_SHORT);
            toast.show();
    }
}

LogCat shows the following:
