Edview (horizontal linear layout); } Horizontal liner layout = new linear layout (getContext ()); BtnZero = New button (getContext ()); btnZero.setText ("0"); HorizontalLinearLayout.addView (btnZero); BtnPoint = new button (getContext ()); BtnPoint.setText ("."); HorizontalLinearLayout.addView (btnPoint); Btndon = new button (getContext ()); BtnDone.setText ("full"); HorizontalLinearLayout.addView (btnDone); VerticalLinearLayout.addView (horizontalLinearLayout); Return vertical liner layout; } Public button getButton () {return button; } Public button getBtnZero () {return btnZero; } Public button getBtnPoint () {return btnPoint; } Public button getBtnDone () {return btnDone; }}
