listview中textview响应部分文本点击事件

</pre>    要在listview的item上实现控件的点击事件,需要专门去写一个adapter类去继承onClickListener,再在主类里去具体的写onClick方法里的内容。<p></p><p>   textView的部分文本点击事件需要对使用这个类SpannableString,其中setSpan方法可以对textView中的部分文本进行处理,包括点击事件,颜色样式等。</p><p>   在开始的时候我认为这两个点击事件会冲突,但最后证明是不影响的。</p><p><pre name="code" class="java">public class ContentAdapter extends BaseAdapter  implements OnClickListener{
	private List<String> mContentList;
       private LayoutInflater mInflater;
       private Callback mcallback;
       public interface Callback           //这个接口必须写,主类必须实现这个     
	{
		   public void click(View v);
         }
	public ContentAdapter(Context context, List<String> contentList,
			            Callback callback) {
			          mContentList = contentList;
			          mInflater = LayoutInflater.from(context);
			          mcallback = callback;
			    }
	public int getCount() {
		return mContentList.size();
	}


	@Override
	public String getItem(int position) {
	
		return mContentList.get(position);
	}


	@Override
	public long getItemId(int position) {
		// TODO Auto-generated method stub
		return position;
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
