安卓TextView实现跑马灯异常问题解决

1、在ListView的intem中放一个TextView要实现跑马灯

style

<style name="listViewItemTvStyle">        <item name="android:layout_width">match_parent</item>        <item name="android:layout_height">match_parent</item>        <item name="android:textColor">@android:color/white</item>        <item name="android:textSize">13sp</item>        <item name="android:singleLine">true</item>        <item name="android:gravity">left</item>        <item name="android:paddingLeft">50px</item>        <item name="android:paddingRight">10px</item>        <item name="android:ellipsize">marquee</item>        <item name="android:marqueeRepeatLimit">marquee_forever</item>    </style>

布局文件如下

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    style="@style/listViewLlRootStyle"    android:id="@+id/ll_item_root"    >    <TextView         android:id="@+id/tv_list_item"        style="@style/carTypeListViewItemTvStyle"        /></LinearLayout>

2、在代码中要实现点击实现高亮效果

list.setOnItemClickListener(carTypeOnItemClickListener);//设置监听

3、适配器

public class ModelAdapter extends BaseAdapter {private String[] dates;private LayoutInflater mInflater;public ModelAdapter(String[] dates,Context context){this.dates = dates;this.mInflater = LayoutInflater.from(context); }@Overridepublic int getCount() {return dates.length>0?dates.length:0;}@Overridepublic Object getItem(int position) {return dates[position];}@Overridepublic long getItemId(int position) {return position;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {ViewHolder holder = null;if(convertView == null){holder = new ViewHolder();  convertView = mInflater.inflate(R.layout.list_item, null);holder.tvTextView = (TextView) convertView.findViewById(R.id.tv_list_item);holder.linearLayout = (LinearLayout) convertView.findViewById(R.id.ll_item_root);holder.tvTextView.setSelected(true);//就是这里，特别重要，要不然没有效果convertView.setTag(holder);}else{holder = (ViewHolder) convertView.getTag();  }holder.tvTextView.setText(dates[position]);if (position == selectItem) {  holder.linearLayout.setBackgroundResource(R.drawable.list_item_p);}else{holder.linearLayout.setBackgroundResource(R.drawable.list_item); }return convertView;}public  void setSelectItem(int selectItem) {this.selectItem = selectItem;}public int getSelectItem(){return selectItem;}private int  selectItem = -1;public class ViewHolder{TextView tvTextView;LinearLayout linearLayout;}}
