【问题描述】：

我正在尝试根据微调器选择在图像视图中显示图像。如果有人知道如何解决这个问题，请帮忙。

public class activity_tables extends AppCompatActivity 

    Spinner s1;
    String[] tbls;

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

        s1 = (Spinner)findViewById(R.id.spinner);


        tbls = getResources().getStringArray(R.array.tables);
          final ArrayAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_spinner_item,tbls);
          adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
          s1.setAdapter(adapter);
    

【参考方案1】：

像这样为您的微调器设置 onItemSelectedListener

    s1.setOnItemSelectedListener(new OnItemSelectedListener() 
            @Override
            public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) 
                // your code here
if(position==0)

qImageView.setImageResource(R.drawable.whatever);
else if(position ==1)

qImageView.setImageResource(R.drawable.whatever);


            

            @Override
            public void onNothingSelected(AdapterView<?> parentView) 
                // your code here
            

        );
