问题描述

有什么不对的code？我想自动使用ID。我认为R.string后有一个错误。我能做些什么

What's wrong with this code? I want to use id automatically. I think after R.string there is a mistake. What can ı do

推荐答案

做这样

public static int getStringIDFromName(String stringName)
{
    int stringID= 0;

    if(stringName == null
            || stringName.equalsIgnoreCase(""))
    {
        return 0;
    }

    try
    {
        @SuppressWarnings("rawtypes")
        Class res = R.string.class;
        Field field = res.getField(stringName);
        stringID = field.getInt(null);
    }
    catch(Exception e)
    {
        // Error
    }

    return stringID;
}

设置你的价值是这样

Set your value like this

int stringVal = getStringIDFromName("i" + j++);
if( stringVal != 0)
    txtt.setText(getResource().getString(stringVal));

如果你正在做的一切好的，这只会工作。

This would work only if you are doing everything else right.
