推荐答案

您可以检查

btnTextDeSave.setOnClickListener(onClickEven);
        btnTextInSave.setOnClickListener(onClickEven);

public OnClickListener onClickEven = new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            switch (v.getId()) {
                break;
            case R.id.btTextDeSave:
                txtDescriptionSave.setTextSize(TypedValue.COMPLEX_UNIT_PX, (txtDescriptionSave.getTextSize() - 2f));
                break;
            case R.id.btTextInSave:
                txtDescriptionSave.setTextSize(TypedValue.COMPLEX_UNIT_PX, (txtDescriptionSave.getTextSize() + 2f));
                break;

            default:
                break;
            }

        }
    };
