java - 在 onCreate 方法中初始化 Strings[]

Question

我正在尝试根据来自上一个 Activity 的值来初始化一个 String[] 数组。编译器说下面的代码有错误，它说“数组常量只能在初始化器中使用”。没有其他选择可以做我想做的事吗？

public class ZeroParameter extends Activity{
int option, model;
String[] models;

protected void onCreate(Bundle savedInstanceState) 
{
    Bundle b = getIntent().getExtras();
    option = b.getInt("option");


    switch(option)
    {
        case 1:
        models={ "Mike" , "Charls" , "Jhon"}
        case 2:
        models={"Paul" , "Louis" };
    }

    super.onCreate(savedInstanceState);
    setContentView(R.layout.zero_parameter);

    final Spinner spinModel=(Spinner)findViewById(R.id.spinnerModel0);
    spinModel.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener()
        {
            public void onItemSelected(AdapterView<?> arg0, View v, int position,long id) 
            {
                    model = spinModel.getSelectedItemPosition();
            }
            public void onNothingSelected(AdapterView<?> arg0) 
        { 
        }
    });

    ArrayAdapter<String> aa= new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,models);
    aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinModel.setAdapter(aa);
}

非常感谢!!!我希望我们能找到解决方案!

改变

switch(option)
{
    case 1:
    models={ "Mike" , "Charls" , "Jhon"};
    case 2:
    models={"Paul" , "Louis" };
}

到

switch(option)
{
    case 1: {
       models=new String[]{ "Mike" , "Charls" , "Jhon"};
       break;
    }
    case 2: {
       models=new String[]{"Paul" , "Louis" };
       break;
    }         
}
