acTextView = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView1); ArrayAdapter adapter = new ArrayAdapter (this,android.R.layout.simple_selectable_list_item,res); acTextView.setAdapter(adapter); 我這個代碼有錯嗎？為啥總報錯？

Eclipse提示錯誤信息為：The method setAdapter(ArrayAdapter<String>) is undefined for the type AutoCompleteTextView

還是報錯，就是最后acTextView.setAdapter(adapter);這一行代碼報錯。

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,res);這樣嗎？

還有ArrayAdapter 要使用泛型 ArrayAdapter<String>

private AutoCompleteTextView acTextView; private String[] res = {"china","chile","chinese","america","amtupo"}; 這是前一段代碼。

有沒有在之前聲明acTextView 比如：AutoCompleteTextView acTextView;
