Question

我正在尝试在android studio上制作一个简单的应用程序，这将允许我选择两个团队（来自旋转器），然后打印出他们的最终分数或者没有玩。

我已经能够完成所有设置和工作，但是我无法在textView中显示得分。它总是说团队没有玩

`public class MainActivity extends AppCompatActivity {
    Spinner spinner1, spinner2;
    ArrayAdapter<CharSequence> adapter1, adapter2;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        spinner1 = (Spinner) findViewById(R.id.spinner1);
            adapter1 = ArrayAdapter.createFromResource(this,R.array.list1,android.R.layout.simple_spinner_item);
            adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
            spinner1.setAdapter(adapter1);
            spinner1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

                @Override
                public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                    TextView spinner1Text = (TextView) view;

                }

            @Override

        else score.setText("Those two teams did not play each other");
