java - 我如何在同一页面中使用两个微调器

public class service extends AppCompatActivity implements AdapterView.OnItemSelectedListener {


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


        Spinner spinner1 = findViewById(R.id.spinner1); // Spinner code
        spinner1.setOnItemSelectedListener(this);

        Spinner spinner2 = findViewById(R.id.spinner2);
        ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
                this,
                R.array.serviceD,
                android.R.layout.simple_spinner_item
        );
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        spinner2.setAdapter(adapter);
        spinner2.setOnItemSelectedListener(this);


    }
 @Override
    public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
        Toast.makeText(this, adapterView.getSelectedItem().toString(), Toast.LENGTH_SHORT).show();
    }

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

    }

如何在同一页面中添加另一个微调器？

最佳答案

在onNothingSelected和onItemSelected方法中，您可以像下面那样检查id-

@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
        int id = adapterView.getId();
        switch (id)
        {
            case R.id.spinner1:
                Log.d("Selected_Value","Spinner 1 : "+adapterView.getItemAtPosition(i).toString());
                break;
            case R.id.spinner2:
                 Log.d("Selected_Value","Spinner 2 : "+adapterView.getItemAtPosition(i).toString());
                break;
        }
    }
