Android ListFragment令人困惑

我对使用ListFragment感到很困惑。。。我不明白问题出在哪里

这是我的碎片活动课：

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;

public class menu extends FragmentActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
            setContentView(R.layout.root_menu); 

        if (getSupportFragmentManager().findFragmentById(android.R.id.content) == null) {
            ListFrag list = new ListFrag();
            getSupportFragmentManager().beginTransaction().replace(android.R.id.content, list).commit();
        }}}

我的ListFragment类：

public class ListFrag extends ListFragment {

    int Files = 0;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // TODO Auto-generated method stub

        getListView().setBackgroundResource(R.drawable.table);
        getListView().setDividerHeight(0);
        getListView().setCacheColorHint(0);

        View view = inflater.inflate(R.layout.main, null);

        return view;
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

        setListAdapter(new CustomListAdapter(getActivity(), getThemes()));
    }

    public String[] getThemes(){
                       ...
        return ...;
    }

还有main.xml（它用于使用我制作的自定义列表适配器制作列表）：

我看到上面说没有创建contentview，但我不明白为什么…

嗯，从logcat：

Caused by: java.lang.IllegalStateException: Content view not yet created

你的问题是：

    getListView().setBackgroundResource(R.drawable.table);
    getListView().setDividerHeight(0);
    getListView().setCacheColorHint(0);

    View view = inflater.inflate(R.layout.main, null);

您正在尝试在设置内容视图之前获取listview。将视图移动到getListView之前

我相信这也将修复关于膨胀类片段的第二个错误。

到底是什么问题？它正在崩溃。。。我将添加log nowFIXED需要禁用onViewCreated方法您没有发布。。。而且（正如我在回答中提到的）你似乎还有其他问题。

public class CustomListAdapter extends ArrayAdapter<String> {
    private final Context context;
    private final String[] values;

    public CustomListAdapter(Context context, String[] values) {
        super(context, R.layout.main, values);
            this.context = context;
            this.values = values;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View rowView = inflater.inflate(R.layout.main, parent, false);

            TextView textView = (TextView) rowView.findViewById(R.id.label);

                ImageView imageView = (ImageView) rowView.findViewById(R.id.icon);

                textView.setText(values[position]);

            imageView.setImageResource(R.drawable.check);

        return rowView;
    }
}
