`我正在创建一个应用程序,其中我从Web服务中获取数据(服务工作正常)并在listview中显示它。为此,我已经创建了自定义适配器类和自定义布局文件。现在每当我尝试将适配器设置为listview时,它都会给我错误:
ZygoteInit $ MethodAndArgsCaller.run()行:762未找到来源 错误
我在下面的java文件中提到了这一行。我不确定eclispe正在谈论哪个来源。我该如何解决它? 提前谢谢。
这是我的适配器类。
公共类CategoryAdapter扩展了BaseAdapter {
Context context;
List<Category> rowItems;
CategoryAdapter(Context context, List<Category> rowItems){
this.context = context;
this.rowItems = rowItems;}
private class ViewHolder {
ImageView image;
TextView cname;
TextView pid;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
LayoutInflater mInflater = (LayoutInflater) context
.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = mInflater.inflate(R.layout.categorylist, null);
holder = new ViewHolder();
holder.image = (ImageView)convertView.findViewById(R.id.cat_image);
holder.cname = (TextView)convertView.findViewById(R.id.cname);
holder.pid =(TextView)convertView.findViewById(R.id.pid);
Category citems = new Category();
citems = rowItems.get(position);
holder.cname.setText(citems.getName());
holder.pid.setText(citems.getId());
convertView.setTag(holder);}
else {
holder = (ViewHolder) convertView.getTag();
}
return convertView;
}
这是xml文件
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="2dp" >
<ImageView
android:id="@+id/cat_image"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_marginTop="14dp"
android:contentDescription="@string/String1"
android:paddingLeft="10dp"
android:paddingRight="10dp" />
<TextView
android:id="@+id/cname"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:layout_toRightOf="@+id/cat_image"
android:paddingBottom="10dp"
/>
<TextView
android:id="@+id/pid"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/cname"
android:layout_below="@+id/cname"
/>
</RelativeLayout>
JAVA文件
protected void onPostExecute(Void result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
//final ArrayAdapter adapter = new ArrayAdapter(this,
// R.layout.categorylist, arrayList);
// listView.setAdapter(adapter);
listView = (ListView) findViewById(R.id.listView1);
CategoryAdapter adapter = new CategoryAdapter(getApplicationContext(), categoryname);
listView.setAdapter(adapter);
如果我评论最后一行listview.setAdapter
,则错误不会来。
基本上它在布局文件或适配器类中缺少某些资源。但是我无法弄清楚我错过了什么。我对此并不十分肯定。 categoryname
是一个列表名称。
恢复时,应用程序崩溃了。 logcat的
