java - 显示两个微调器的输出

Question

我正在尝试在 android studio 上制作一个简单的应用程序，它允许我选择两支球队(从旋转器中)，然后打印出他们的最终得分或不参加比赛。

我已经能够完成整个设置并正常工作，但是我无法在 TextView 中显示分数。它总是只是说球队没有参加比赛

`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
            public void onNothingSelected(AdapterView<?> parent) {

            }
        });
        spinner2 = (Spinner) findViewById(R.id.spinner2);
        adapter2 = ArrayAdapter.createFromResource(this,R.array.list2,android.R.layout.simple_spinner_item);
        adapter2.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner2.setAdapter(adapter2);
        spinner2.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

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

            }


            @Override
            public void onNothingSelected(AdapterView<?> parent) {

            }
        });
       final Button button = (Button)findViewById(R.id.Show);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
             button.refreshDrawableState();
            }
        });

        TextView score = (TextView) findViewById(R.id.Score);

        if (spinner1.getSelectedItem().toString().equals("Patriots")&& spinner2.getSelectedItem().toString().equals("Seahawks")) {
            score.setText("Patriots 21, Seahawks 14" + "\n" + "Q1 Patroits 3 Seahawks 0" + "\n" + "Q2 Patroits 3 Seahawks 14" + "\n" + "Q3 Patroits 14 Seahawks 14" + "\n" + "Q4 Patroits 21 Seahawks 14");}

       else if (spinner1.getSelectedItem().toString().equals("Falcons")&& spinner2.getSelectedItem().toString().equals("Raiders")){
            score.setText("Falcons 3, Raiders 18" + "\n" + "Q1 Falcons 0 Raider 0" + "\n" + "Q2 Falcons 0 Raider 13" + "\n" + "Q3 Falcons 0 Raider 15" + "\n" + "Q4 Falcons 0 Raider 18");}

        else if (spinner1.getSelectedItem().toString().equals("Eagles")&& spinner2.getSelectedItem().toString().equals("Cowboys")){
            score.setText("Eagles 42, Cowboys 38" + "\n" + "Q1 Eagles 3 Cowboys 21" + "\n" + "Q2 Eagles 21 Cowboys 29" + "\n" + "Q3 Eagles 28 Cowboys 35" + "\n" + "Q4 Eagles 42 Cowboys 38");}

        else if (spinner1.getSelectedItem().toString().equals("Bears")&& spinner2.getSelectedItem().toString().equals("Redskins")){
            score.setText("Bears 20, Redskins 0" + "\n" + "Q1 Bears 3 Redskins 0" + "\n" + "Q2 Bears 3 Redskins 0" + "\n" + "Q3 Bears 17 Redskins 0" + "\n" + "Q4 Bears 20 Redskins 0");}

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

谢谢 Pavneet Singh，我只需要把 if-else 移到监听器
