Question

这是我的片段类

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

public class CommunityFragment extends Fragment {

    public CommunityFragment(){}

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.fragment_community, container, false);

        return rootView;
    }
}

以下是其简单的 xml ，其中当我尝试添加 listview标记时，会出现错误

    <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

<ListView
    android:id="@+id/listview"
    android:layout_marginTop="10dp"
    android:background="@drawable/bg"
    android:divider="#9c9c9c"
    android:dividerHeight="5dp"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" />

    </RelativeLayout>

这是StackTrace

是否可以在片段类中添加listview？希望有人可以帮助我，谢谢你！

Answer 1

我想发表评论，但没有足够的声誉...... 从你的堆栈跟踪看起来我的问题是在加载listview的背景时，这个图像可能很大。

尝试从列表视图中删除背景drawable或用简单的颜色替换它。

您可以通过以下方式执行此操作 -

public class CommunityFragment extends Fragment {

public CommunityFragment(){}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {

View rootView = inflater.inflate(R.layout.fragment_community, container, false);
View lv1 = rootView .findViewById(R.id.listView);

String[] values = new String[] { "Android", "iPhone", "WindowsMobile",
                    "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X",
               "Linux", "OS/2" };

ArrayAdapter<String> files = new ArrayAdapter<String>(getActivity(), 
                        android.R.layout.simple_list_item_1, values);
lv1.setAdapter(files);
return rootView;
        }
}
