Android Spinner错误:android.view.WindowManager $ BadTokenException:无法添加窗口

Question

我想使用String []或ArrayList设置微调器值.

我在其他活动中做了微调器工作正常.在Tab acivityGroup内的这个活动中另一个Tab活动.

我的问题是将值设置为微调器.Spinner正确显示Thay意味着在加载活动时,工作正常但是当我单击On spinner时它会给出错误:

错误是:

这是我的代码:

   View viewToLoad = LayoutInflater.from(this.getParent()).inflate(R.layout.line_discount, null);
    this.setContentView(viewToLoad); 

   ArrayList<String> productList = new ArrayList<String>();
    int size = products.size()+1;
    String[] proList = new String[size];
    proList[0] = "---Select----";

    for(int i = 1; i< size ;i++){
        productList.add(products.get(i-1).getDescription());
        proList[i] = products.get(i-1).getDescription();
    }

    sp = (Spinner)findViewById(R.id.spProList);
    ArrayAdapter<String> adapter = new ArrayAdapter<String> (LineDiscountActivity.this, android.R.layout.simple_spinner_item, proList);
    sp.setAdapter(adapter);

这是我的形象:

TabActivity中的问题.因为我在TabActivityGroup中运行了这个部分.它正在工作.当我在TabActivityGroup中的Tab Activity中运行它时,那就是一个问题.我有TabActivtyGroup&在正常的TabActivity内.

在这种情况下我该怎么办？

Answer 1

我认为你有上下文问题.尝试使用以下方法获取上下文

您可以创建一个新活动并将其主题设置为,dialog theme以便在您开始活动时它将显示为对话框.有关对话框的更多信息,请参见下文

我找到了解决方案 badTokenExcaption

在您的活动的onCreate()方法代替线setContentView(R.layout.XXXXX)由

View viewToLoad = LayoutInflater.from(this.getParent()).inflate(R.layout.XXXXX, null);
this.setContentView(viewToLoad); 

并通过以下行替换微调器代码

ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource( this, R.array.medicine_types, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_item);
spDosageType.setAdapter(adapter);
