Android的微调适配器设置为微调器 [英] Android Spinner Adapter Setting to spinner

问题描述

我使用eneter框架来处理我的Andr​​oid应用程序通信;
问题是，当我试图填充微调，适配器设置为微调事业未定义例外

在这里，code

 公共无效populateSpinner（TypedResponseReceivedEventArgs＆LT;串GT; ARG1）{
    清单＆LT;串GT;名单=新的ArrayList＆LT;串GT;（）;
    串LISTF = arg1.getResponseMessage（）;
    // sendToDebug（LISTF）;
    StringTokenizer的标记生成器=新的StringTokenizer（LISTF，）;
    而（tokenizer.hasMoreElements（））{
        list.add（（字符串）tokenizer.nextElement（））;
    }
    //文字的EditText =（EditText上）findViewById（R.id.number2EditText）;
    //text.setText（则为list.size（））;
    //text.setText(listf）;
    微调forfait =（微调）findViewById（R.id.forfaitsSpinner）;
            ArrayAdapter＆LT;串GT;适配器=新ArrayAdapter＆LT;串GT;（这一点，android.R.layout.simple_spinner_item，清​​单）;
    adapter.setDropDownViewResource（android.R.layout.simple_spinner_dropdown_item）;
    forfait.setAdapter（适配器）;
}
 

解决方案

你逝去的这个在下面的一段code的，

  ArrayAdapter＆LT;串GT;适配器=新ArrayAdapter＆LT;串GT;（这一点，android.R.layout.simple_spinner_item，清​​单）;
 

不知道在阻止这种code在于或哪一类，但要确保 这个 指 ActivityName.class 或上下文

I'm using eneter framework to process communication in my android application; the problem is when I'm trying to populate a spinner, setting the adapter to the spinner cause an undefined exception

Here the code

public void populateSpinner(TypedResponseReceivedEventArgs<String> arg1){
    List<String> list = new ArrayList<String>();
    String listf = arg1.getResponseMessage();
    //sendToDebug(listf);
    StringTokenizer tokenizer = new StringTokenizer(listf,",");
    while(tokenizer.hasMoreElements()){
        list.add((String)tokenizer.nextElement());
    }
    //EditText text = (EditText)findViewById(R.id.number2EditText);
    //text.setText(list.size());
    //text.setText(listf);
    Spinner forfait = (Spinner)findViewById(R.id.forfaitsSpinner);
            ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,list);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    forfait.setAdapter(adapter);
}

解决方案

you are passing this in the following piece of code,

 ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,list);

Not sure in which block this code lies or which class, but ensure that this refers to ActivityName.class or the context
