OnClick脚本出错

Question

    myOnClickListener = new MyOnClickListener(this);
    nRecyclerView = (RecyclerView) findViewById(R.id.my_recycler2_view);
    nRecyclerView.setHasFixedSize(true);

static class MyOnClickListener implements View.OnClickListener{

    private final Context context;
    private MyOnClickListener(Context context) {
        this.context = context;
    }

    public void onClick(View v) {
        checkWhich(v);
    }

    private static void checkWhich (View v){
        int selectedItemPosition = nRecyclerView.getChildPosition(v);
        RecyclerView.ViewHolder nViewHolder = nRecyclerView.findViewHolderForPosition (selectedItemPosition);

        TextView textViewName = (TextView) nViewHolder.itemView.findViewById(R.id.textViewCountry);
        String selectedName = (String) textViewName.getText();
        for (int i = 0; i  < MyData.countryArray.length; i++){
            if (selectedName==MyData.countryArray[i]) {
                System.out.println(selectedName);
            }
        }
    }
}

这之前已经奏效，但现在还没有奏效。我做错了什么吗？我有2个RecyclerViews但它们在一起不可见。此单击侦听器仅适用于一个RecyclerView。

logcat的

实施View.OnClickListener时，请执行以下操作。

public class YourClass extends Activity implements View.OnClickListener

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        //Component setup here. 
        nRecyclerView = (RecyclerView) findViewById(R.id.my_recycler2_view);
        nRecyclerView.setHasFixedSize(true);
        nRecyclerView.setOnClickListener(this);
    }    

    @Override
    public void onClick(View v) {
        checkWhich(v);
    }

    private static void checkWhich (View v){
        int selectedItemPosition = nRecyclerView.getChildPosition(v);
        RecyclerView.ViewHolder nViewHolder = nRecyclerView.findViewHolderForPosition (selectedItemPosition);

        TextView textViewName = (TextView) nViewHolder.itemView.findViewById(R.id.textViewCountry);
        String selectedName = textViewName.getText().toString();
        for (int i = 0; i  < MyData.countryArray.length; i++){
            if (selectedName==MyData.countryArray[i]) {
                System.out.println(selectedName);
            }
        }
    }
}
