得到一个字符串数组资源与一个字符串变量 [英] getting a stringArray resource with a string variable
问题描述
我试图让这个code一个字符串数组资源:
I am trying to get a stringArray resource with this code:
String continent = "europe";
getResources().getStringArray(R.array.continent);
如果我输入R.array.europe,其确定,但我想这是动态的,所以我在寻找一种方法,在这里使用我的字符串变量。
If I type R.array.europe, its ok, but I want this to be dynamic, so I'm looking for a way to use my string variable here..
这可能是一个简单的Java问题,但我都在Java和Android编程相当小白,我没有找到答案。
This is probably a simple java problem, but I'm quite a noob both in java and android programming, and I didn't find the answer..
在此先感谢;
编辑:所以这里是我的完整onCreate方法,我有没有做错事
edit: so here is my complete onCreate Method, did I do something wrong?
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.second);
String continent = (String) getIntent().getExtras().getString("continent");
int holderint = getResources().getIdentifier(continent, "Array",
this.getPackageName());
String[] items = getResources().getStringArray(holderint);
setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,
items));
}
我不知道有关defPackage部分虽然...
I'm not sure about the defPackage part though...
推荐答案
随着code动态创建的资源的名称,你可以看看使用
With the name of the resource created dynamically in code, you could look at using
getResources().getIdentifier(String name, String defType, String defPackage);
这将返回一个ID为指定资源。
This will return an id for a specified resource.
