Android开发中autocompletetextview怎么不能自动显示

adapter写的有问题吧，我没用过自定义adapter，之前用arrayadapter就直接设置就可以了

//初始化Adapter

ArrayAdapter adapter = new ArrayAdapter<String>(getApplicationContext(),

android.R.layout.simple_dropdown_item_1line, all_list)

//对自动补全控件设置绑定的Adapter

et.setAdapter(adapter)

你先用arrayAdapter试一下看看是不是adapter的问题。再答应一下看看cursor取数据取得有没有问题。
