Question

 private String[] genre = { "Action", "Adventure", "Comedy", "Biography", "Drama", "Family", "Horror", "Romance" }; 
 private Integer images[] = { R.drawable.img_action, R.drawable.img_adventure, R.drawable.img_biografy, R.drawable.img_comedy, R.drawable.img_drama, R.drawable.img_family, R.drawable.img_horror, R.drawable.img_romantis };
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    setInitialImage();

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

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(       // make array adapter
            this, android.R.layout.simple_spinner_item, genre
        );

    spinner.setAdapter(adapter);   // connect adapter with  spinner
    spinner.setOnItemSelectedListener(new OnItemSelectedListener() {     // get item from spinner

        @Override
        public void onItemSelected(AdapterView<?> parent, View view,
                int position, long id) {
            // TODO Auto-generated method stub
            int index = spinner.getSelectedItemPosition();

            if () {

                currImage = images[0];  
                Toast.makeText(getBaseContext(), "Anda memilih genre film "+ genre[index], Toast.LENGTH_SHORT)
                .show();
            }
            setCurrentImage(); // called method

        }

    });     

}

当我点击其中一个微调器项目时，将显示电影类型的图像。我应该在if语句中键入什么内容？

任何人都可以帮我解决这个问题吗？

将onItemSelectedMethod修改为

@Override
public void onItemSelected(AdapterView<?> parent, View view,
                int position, long id) {
      currImage = images[position];  
      Toast.makeText(getBaseContext(), "Anda memilih genre film "+ genre[index], Toast.LENGTH_SHORT)
                .show();
      setCurrentImage(); // called method
}

当我选择微调项目时如何显示ImageView
