我在home.class一个微调。当我点击微调，该过程停止显示异常窗口管理$ BadTockenException被抓住了。

I have a spinner in my home.class. When I click on the spinner, the process is stopped showing exception that WindowManager$BadTockenException is caught.

我打电话这个home.class从main.class延伸的ActivityGroup。

I am calling this home.class from main.class which extends ActivityGroup.

如果我仅仅只能运行home.class，微调是显示所有项目。但问题不仅是从main.class调用home.class。

If I am simply run only the home.class, the spinner is showing all items. But the problem is only with calling home.class from main.class.

下面是我的code。请告诉我这是为什么发生了。

The following are my code. Please tell me why this is happened.

public class main extends ActivityGroup
{
  public void onCreate(Bundle savedInstanceState)
  {
      super.onCreate(savedInstanceState);
       Intent intent=new Intent(this,home.class);
       View view=getLocalActivityManager().startActivity("1", intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView();
       setContentView(view);
  }

}

String[] country={"Please selects","US","INDIA","UK"};
Spinner s2 = (Spinner) findViewById(R.id.spinnerCountry);
ArrayAdapter<CharSequence> adapterCountry=new ArrayAdapter(this,android.R.layout.simple_spinner_item,country);
adapterCountry.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
s2.setAdapter(adapterCountry);

s2.setOnItemSelectedListener(new OnItemSelectedListener()
{
     public void onItemSelected( AdapterView<?> parent, View view, int position, long id)
     {
            countryName=country[position];
     }

      public void onNothingSelected(AdapterView<?> parent)
     {
            countryName=country[0];
      }

}）;

推荐答案

该错误可能是您的home.class内给予的setContentView。

The error may be with the setContentView given inside your home.class.

而不是的setContentView的（yourlayout）;

放弃，

View viewToLoad = LayoutInflater.from(this.getParent()).inflate(yourlayout, null);
this.setContentView(viewToLoad);  
Spinner s2 = (Spinner) viewToLoad.findViewById(R.id.spinnerCountry);

和给你的微调code为：

And give your spinner code as:

ArrayAdapter<CharSequence> adapterCountry=new ArrayAdapter(this.getParent(),android.R.layout.simple_spinner_item,country);
adapterCountry.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
s2.setAdapter(adapterCountry);

由于您使用的是活动组，你面对这个问题。希望这个解决方案可以帮助你。

Since you are using activity group, you face this issue. Hope this solution may help you.
