更新微調錯誤

我在Activity上有這段代碼，我回頭再看這個活動並更新ArrayList數據。更新微調錯誤

{ArrayAdapter<String> adaptador =  
    new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, datos); 

spinnerD = (Spinner)findViewById(R.id.spinner1); 

adaptador.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
spinnerD.setAdapter(adaptador);

當我試圖「重啓」我收到以下錯誤的活動後，打開微調：

你有沒有使用過spinnerD.setAdapter（adaptador）; ？另外，哪行代碼是355？ –

該錯誤甚至不是一個錯誤，只是對一行代碼的引用。什麼是完整的錯誤文本 – MrZander

spinnerD.setAdapter(adaptador1);

是什麼adaptador1，要創建「adaptador」，然後你將adaptador1設置爲您的spinnerD.setAdapter(adaptador1)。它是否正確？ 'adaptador1'可能爲空/空。

你是說它應該是空的或者是空的，這就是爲什麼我有錯誤？在我做spinnerD.setAdapter（adaptador）之前，adaptador並不是空的。 –
