自定义listView的Item的样式出现问题 求教
我现在自己定义一个ListView Item的样式报错误如下：
- Java code
07-26 06:18:03.717: ERROR/ArrayAdapter(723): You must supply a resource ID for a TextView07-26 06:18:03.826: ERROR/AndroidRuntime(723): java.lang.IllegalStateException: ArrayAdapter requires the resource ID to be a TextView07-26 06:18:03.826: ERROR/AndroidRuntime(723): at 07-26 06:18:03.826: ERROR/AndroidRuntime(723): Caused by: java.lang.ClassCastException: android.widget.RelativeLayout07-26 06:18:03.826: ERROR/AndroidRuntime(723): at android.widget.Array
有没有人以前也遇到过相似的问题 ，求解答。万分感激。
代码如下：
- XML code
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/flowListRow" android:background="@drawable/news_bg" android:layout_width="fill_parent" android:layout_height="40dp"> <TextView android:id="@+id/flow_type" android:text="请假及出差申请" android:textColor="#696969" android:layout_alignParentLeft="true" android:layout_height="wrap_content" android:textSize="6dip" android:layout_marginTop="1dip" android:textAppearance="?android:attr/textAppearanceLarge" android:layout_marginLeft="5dp" android:ellipsize="end" android:layout_width="match_parent" android:scrollHorizontally="true" /> <TextView android:id="@+id/flow_name" android:text="年休假申请" android:textColor="@color/black" android:layout_marginTop="1dip" android:layout_below="@id/flow_type" android:layout_alignParentLeft="true" android:layout_marginLeft="8dp" android:textSize="12dip" android:layout_width="match_parent" android:layout_height="wrap_content" > </TextView> <TextView android:id="@+id/below_node" android:text="上一节点" android:textColor="@color/black" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" android:layout_marginLeft="6dp" android:textSize="6dip" android:layout_marginTop="1dip" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignTop="@+id/flow_autor"> </TextView> <TextView android:id="@+id/flow_autor" android:layout_width="wrap_content" android:textSize="8dip" android:text="申请人：*** 2012-07-01" android:textColor="@color/black" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_alignParentRight="true"></TextView> </RelativeLayout>
然后自己定义了一个adapter
- Java code
package com.hundsun.zhou.adapter;import java.util.ArrayList;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.ArrayAdapter;import android.widget.BaseAdapter;import android.widget.LinearLayout;import android.widget.RelativeLayout;import android.widget.TextView;import com.hundsun.zhou.R;import com.hundsun.zhou.vo.FlowVO;/** * @author zhoujl * @since 2012/07/26 10:17:38 */public class FlowListAdapter extends BaseAdapter { private Context context; private ArrayList<FlowVO> mData ; // private LayoutInflater mInflater; // private int textViewResourceId; /** * @param context * @param resource * @param textViewResourceId * @param objects */ public FlowListAdapter(Context context ) { this.context = context; //mInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); } public FlowListAdapter(Context context,ArrayList<FlowVO> list ) { this.context = context; this.mData = list; //mInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); } public void addItem(FlowVO flowVO) { mData.add(flowVO); notifyDataSetChanged(); } public void removeItem(int position) { mData.remove(position); notifyDataSetChanged(); } @Override public int getCount() { return mData.size(); } @Override public FlowVO getItem(int position) { return (FlowVO)mData.get(position); } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { /* ViewHolder holder = null; FlowVO data = mData.get(position); holder = new ViewHolder(); //RelativeLayout llContent = (RelativeLayout) convertView.findViewById(R.id.flowListRow); convertView = mInflater.inflate(textViewResourceId, null); holder.textView = (TextView)convertView.findViewById(R.id.flow_type); holder.textView1 = (TextView)convertView.findViewById(R.id.flow_name); holder.textView2 = (TextView)convertView.findViewById(R.id.below_node); holder.textView3 = (TextView)convertView.findViewById(R.id.flow_autor); holder.textView.setText(data.getFlowType()); holder.textView1.setText(data.getFlowName()); holder.textView2.setText(data.getFlowBelowNodeName()); holder.textView3.setText(data.getFlowAutorName()); //llContent.addView(holder.textView); //llContent.addView(holder.textView1); //llContent.addView(holder.textView2); //llContent.addView(holder.textView3); convertView.setTag(holder); return convertView;*/ if(mData == null) { return null; } if(convertView == null) { FlowListItemView flowListItemView= new FlowListItemView(context); flowListItemView.updateView(mData.get(position)); convertView =flowListItemView; }else { ((FlowListItemView)convertView).updateView(mData.get(position)); } return convertView; } }flowListItemView
- Java code
package com.hundsun.zhou.adapter;import com.hundsun.zhou.R;import com.hundsun.zhou.vo.FlowVO;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.widget.LinearLayout;import android.widget.RelativeLayout;import android.widget.TextView;/** * @author zhoujl * @since 2012/07/26 13:41:17 */public class FlowListItemView extends RelativeLayout { private Context context; private TextView flowName,flowType,flowAutor,flowBelowNodeName; public FlowListItemView(Context context) { super(context); this.context = context; init(context); } public void init(Context context) { this.context = context; View view = LayoutInflater.from(this.context).inflate(R.layout.flow_list_row, null); flowName = (TextView)view.findViewById(R.id.flow_name); flowType = (TextView)view.findViewById(R.id.flow_type); flowAutor = (TextView)view.findViewById(R.id.flow_autor); flowBelowNodeName = (TextView)view.findViewById(R.id.below_node); addView(view); } public void updateView(FlowVO flowVO) { flowName.setText(flowVO.getFlowName()); flowType.setText(flowVO.getFlowType()); flowAutor.setText(flowVO.getFlowAutorName()); flowBelowNodeName.setText(flowVO.getFlowBelowNodeName()); } }
[解决办法]
尝试以下方法：
将addView(view);改为setContentView(view);
将
flowName.setText(flowVO.getFlowName());
flowType.setText(flowVO.getFlowType());
flowAutor.setText(flowVO.getFlowAutorName());
flowBelowNodeName.setText(flowVO.getFlowBelowNodeName());
修改为
flowName.setText(flowVO.getFlowName() + "");
flowType.setText(flowVO.getFlowType() + "");
flowAutor.setText(flowVO.getFlowAutorName() + "");
flowBelowNodeName.setText(flowVO.getFlowBelowNodeName() + "");
[解决办法]
项目clear一下！
