我的片段类

package com.example.neelay.anotherbeatbox.Fragment;


import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

 import com.example.neelay.anotherbeatbox.R;


public class Songs extends Fragment {


public Songs() {
    // Required empty public constructor
}


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    return inflater.inflate(R.layout.fragment_songs, container, false);
}

}

推荐答案

替换

<view

使用

<View

View是可以充气的实际小部件，似乎符合您的预期目的. view是一个特殊的标记，您可以使用它在属性中定义的名称来为视图类充气，而您尚未定义此类名称(在充气机中为null出现).

View is an actual widget you can inflate and seems to fit your intended purpose. view is a special tag and with it you can inflate view classes by a name defined in attributes, and you have not defined such class name (it comes up as null in inflater).
