无法解析构造函数ArrayAdapter(Listview，fragment) [英] Cannot resolve constructor ArrayAdapter (Listview , fragment )

问题描述

我想在片段中加载一个列表视图，适配器的问题是错误-Cannot resolve constructor ArrayAdapter.

I want to load a listview in my fragment and the problem with the adapter is the error - Cannot resolve constructor ArrayAdapter.

这是我班上的onCreateView方法:

 public class AndroidGUIModifier implements IMyComponentGUIModifier, IFragmentEvents {

    @Override
    public void onCreateView() {
        tv1 = (TextView) fragment.findViewById("xtv1");
        tv2 = (TextView) fragment.findViewById("xtv2");
        lv=(ListView) fragment.findViewById("xdevices") ;

        mydevices = new ArrayList<String>();

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(AndroidGUIModifier.this,android.R.layout.simple_list_item_1,mydevices);// the problem here : Cannot resolve constructor ArrayAdapter

        lv.setAdapter(adapter);
    }

}

推荐答案

从片段中获取Context并将其传递给ArrayAdapter:

Obtain the Context from the fragment and just pass it to the ArrayAdapter :

ArrayAdapter<String> adapter = new ArrayAdapter<String>(fragment.getContext(), android.R.layout.simple_list_item_1, mydevices);
