Android Studio＆＃34; R.array＆＃34;错误：（36,44）错误：找不到符号变量数组

Question

错误突出显示文本＆＃34;数组＆＃34;红色。我该如何解决？

public class Signup extends Activity {

    AutoCompleteTextView y;
    String[] z;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.signup);

        y = (AutoCompleteTextView) findViewById(R.id.cntry);
        z = getResources().getStringArray(R.array.country);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, z);

Answer 1

您在res / values文件夹中的arrays.xml文件中使用TypedArray，如下所示：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string-array name="country">
        <item>@drawable/pakistan</item>
        <item>@drawable/india</item>
        <item>@drawable/USA</item>
    </string-array>
</resources>
