如何访问android TypedArray中的第N个字符串数组？尝试按事件访问TypedArray是行不通的，奇怪的是它似乎不是一个定义的getStringArray（）公共方法。

代码如下所示：

//Get array of breed stats by index contained in breed index.
Resources res = getResources();
TypedArray dogBreedInfo = res.obtainTypedArray(R.array.dog_breeds);
String[] selected_breedInfo = dogBreedInfo.get***?????***(breed,0);

<array name="dog_breeds">
       <item>
            <string-array name="black_russian_terrier">
                <item>Working Dogs</item>
                <item>2\'2" - 2\'6"</item>
                <item>80 - 140 lbs</item>
                <item>10 - 11 years</item>
            </string-array>
       </item>
       <item>
            <string-array name="boxer">
                <item>Working Dogs</item>
                <item>1\'9" - 2\'1"</item>
                <item>60 - 70 lbs</item>
                <item>10 - 12 years</item>
            </string-array>
       </item>

Answer 1

你可以试试这个！

getResources().getStringArray(R.id.dog_breeds)[selectedIndex];

我建议你更改你的xml文件：

对不同的品种信息使用单独的array：

      <array name="Type_of_dog">
            <item>black_russian_terrier</item>
            <item>boxer</item>
            <item>3rd type</item>
            <item>4th type</item>
      </array>


      <array name="characteristic_1">
            <item>Working Dogs</item>
            <item>Working Dogs</item>
            <item>...</item>
            <item>...</item>
      </array>

      <array name="characteristic_2">
            <item>2\'2" - 2\'6"</item>
            <item>1\'9" - 2\'1"</item>
            <item>...</item>
            <item>...</item>
      </array>

      <array name="characteristic_3">
            <item>80 - 140 lbs</item>
            <item>60 - 70 lbs</item>
            <item>...</item>
            <item>...</item>
      </array>

      <array name="characteristic_4">
            <item>10 - 11 years</item>
            <item>10 - 12 years</item>
            <item>...</item>
            <item>...</item>
      </array>

从Java文件中访问它们：

public void getBreedInfo(int index){
    Resources resources = getResources();
    TypedArray type = resources.obtainTypedArray(R.array.Type_of_dog);
    TypedArray char1 = resources.obtainTypedArray(R.array.characteristic_1);
    TypedArray char2 = resources.obtainTypedArray(R.array.characteristic_2);
    TypedArray char3 = resources.obtainTypedArray(R.array.characteristic_3);
    TypedArray char4 = resources.obtainTypedArray(R.array.characteristic_4);

   if(type.equals("black_russian_terrier")) {
       // do it something for type 1
   } else if(type.equals("boxer") {
       // do it something for type 2
   }

    type.recycle();
    char1.recycle();
    char2.recycle();
    char3.recycle();
    char4.recycle();

}

Answer 3

您可以从我的详细答案中提取您的需求。

CharSequence[] infos;
TypedArray a = mContext.getTheme().obtainStyledAttributes(attrs, R.styleable.PostableEditText, 0, 0);


try {
       infos = a.getTextArray(R.styleable.PostableEditText_infos);
    }
    finally {
        a.recycle();
    }

attrs.xml

<declare-styleable name="PostableEditText">
    <attr name="infos" format="reference" />
</declare-styleable>

您的custom_layout.xml

<com.my.app.views.custom.edittext.PostableEditText
    android:id="@+id/orderProduct"
    android:layout_width="match_parent"
    android:layout_height="55dp"
    app:infos="@array/orderProductInfos" />

ids.xml

<array name="orderProductInfos">
    <item>@string/Price</item>
    <item>@string/Name</item>
    <item>@string/Id</item>
</array>

strings.xml

<!-- Order Product Infos -->
<string name="Price">Price</string>
<string name="Name">Name</string>
<string name="Id">Id</string>
