private String getRealName(String nickName) { String realName = ""; switch (nickName) { case "SG": realName = "Necklace"; break; case "AX": realName = "Bracelet"; break; case "HX": realName = "Earrings"; break; default: realName = "Others"; break; } return realName; } } public void reader(String epc) { String upc = epc; //UpcUtils.getUPC(epc); Stock s; String abbreviation = ""; String nickName = upc.replaceAll("@+", ""); String slName = nickName.substring(0, 2); String realName = getRealName(slName); s = new Stock(upc, upc, realName, realName); s.setTime(FileUtil.getTimes()); s.setAbbreviation(abbreviation); //adapter.update(s); long count = Long.parseLong(btn_update.getText().toString()) + 1; btn_update.setText(String.valueOf(count)); }根据不同的case分别对btn_upload进行赋值怎么做

您可以在每个case语句中添加对btn_upload的赋值，比如：

switch (nickName) {
    case "SG":
        realName = "Necklace";
        btn_upload.setText("Necklace");
        break;
    case "AX":
        realName = "Bracelet";
        btn_upload.setText("Bracelet");
        break;
    case "HX":
        realName = "Earrings";
        btn_upload.setText("Earrings");
        break;
    default:
        realName = "Others";
        btn_upload.setText("Others");
        break;
}

这样，当getRealName()函数返回不同的realName时，btn_upload的文本内容也会相应地变化。
