/*Spinner Functions*/
public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
    soundSelection = (Integer) parent.getItemAtPosition(pos);
}

public void onNothingSelected(AdapterView<?> parent) {
      // Do nothing.
}

}

Answer 1

`onItemSelected`

返回你的位置并使用这个位置你需要提取值。当您使用资源时，您应该在本地变量中获取其值，并从中获取值....

Answer 2

以下是解决方案如何从Spinner获取所选项目

public class YourItemSelectedListener implements OnItemSelectedListener {

public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
    String selected = parent.getItemAtPosition(pos).toString();
}

public void onNothingSelected(AdapterView parent) {
    // Do nothing.
}
}
