setOnItemClickListener没有响应自定义的ListView

问题描述

我写了一个自定义的适配器列表视图，但是当我试图实现单击事件列表项，我发现它是没有回应，我会很高兴，如果有人建议我一个解决方案。

 公共类TourList扩展ListActivity {
....
的setContentView（R.layout.tourlist）;
.....





getListView（）。setOnItemClickListener（新OnItemClickListener（）{
            公共无效onItemClick（适配器视图＆LT;＆GT;母公司视图中查看，INT位置，长的id）{
                     //我不能达到这里
             Log.v（TAG，没有ü得到我）;
        }
      }）;
ADAP =新MyAdapter（TourList.this，mylist中）;
getListView（）setAdapter（ADAP）。
 

和我的自定义适配器

 私有类MyAdapter扩展了BaseAdapter {

            ArrayList的＆LT; HashMap的＆LT;字符串，字符串＆GT;＆GT;元素;
            上下文CTX;

            公共MyAdapter（上下文的背景下，ArrayList的＆LT; HashMap的＆LT;字符串，字符串＆GT;＆GT; mylist中）{
                  this.elements = mylist中;
                  this.ctx =背景;
             }

            公共布尔的IsEnabled（INT位置）{
               返回true;
                      }

            @覆盖
            公众诠释getCount将（）{
                返回elements.size（）;
                }
            @覆盖
            公共对象的getItem（INT位置）{
                返回elements.get（位置）;
                }
            @覆盖
            众长getItemId（INT位置）{
                返回的位置;
                }
                @覆盖
            公共查看getView（INT位置，查看convertView，ViewGroup中父）{
                视图V = convertView;
                如果（convertView == NULL）{
                      LayoutInflater VI =（LayoutInflater）getSystemService（Context.LAYOUT_INFLATER_SERVICE）;
                      V = vi.inflate（R.layout.rowfor_tourlist，NULL）;
                 }

                    TextView的时间=（TextView中）v.findViewById（R.id.intro）;
                    TextView的杜=（TextView中）v.findViewById（R.id.duration）;
                    TextView的PF =（TextView中）v.findViewById（R.id.price）;
                    TextView的PN =（TextView中）v.findViewById（R.id.product）;
                    的WebView WV =（web视图）v.findViewById（R.id.photo）;
                    in.setText（Html.fromHtml（mylist.get（位置）获得（简介）））;
                    du.setText（mylist.get（位置）获得（持续时间））;
                    pf.setText（mylist.get（位置）获得（价格））;
                    pn.setText（mylist.get（位置）获得（产品））;
                    wv.getSettings（）setJavaScriptEnabled（真）。
                    wv.loadUrl（mylist.get（位置）获得（IMAGEURL））;

                返回伏;
            }
        }//类
 

和我的tourlist.xml文件看起来像

 ＆LT;的LinearLayout
        机器人：layout_width =FILL_PARENT
        机器人：layout_height =FILL_PARENT
            ....
        ＆GT;

 ＆LT; ListView的机器人：ID =@ ID / Android的：清单
           机器人：layout_width =FILL_PARENT
           机器人：layout_height =FILL_PARENT
           机器人：背景=@可绘制/白
            机器人：cacheColorHint =＃00000000
           机器人：layout_weight =1

           /＆GT;
＆LT; /...& GT;

看看this讨论可以帮助...

I wrote a custom Adapter for a listview ,but when i tried implement click event for list item ,i found that it was not responding ,I will be glad if someone suggest me a solution.

public class TourList extends ListActivity {
....
setContentView(R.layout.tourlist);
.....





getListView().setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
                     //i couldn't reach here
             Log.v(TAG,"did u get me");
        }
      });
adap = new MyAdapter(TourList.this,mylist);
getListView().setAdapter(adap);

and my custom adapter is

private class MyAdapter extends BaseAdapter {

            ArrayList<HashMap<String,String>> elements;
            Context ctx;

            public MyAdapter(Context context, ArrayList<HashMap<String,String>> mylist) {
                  this.elements=mylist;
                  this.ctx=context;
             }

            public boolean isEnabled(int position){
               return true;
                      }

            @Override
            public int getCount() {
                return elements.size();
                }
            @Override
            public Object getItem(int position) {
                return elements.get(position);
                }
            @Override
            public long getItemId(int position) {
                return position;
                }
                @Override
            public View getView(int position, View convertView, ViewGroup parent) {
                View v = convertView;
                if (convertView == null) {
                      LayoutInflater vi = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                      v = vi.inflate(R.layout.rowfor_tourlist, null);
                 }

                    TextView in = (TextView)v.findViewById(R.id.intro);
                    TextView du = (TextView)v.findViewById(R.id.duration);
                    TextView pf = (TextView)v.findViewById(R.id.price);
                    TextView pn = (TextView)v.findViewById(R.id.product);
                    WebView wv=(WebView)v.findViewById(R.id.photo);
                    in.setText(Html.fromHtml(mylist.get(position).get("Intro")));
                    du.setText(mylist.get(position).get("Duration"));
                    pf.setText(mylist.get(position).get("Price"));
                    pn.setText(mylist.get(position).get("Product"));
                    wv.getSettings().setJavaScriptEnabled(true);
                    wv.loadUrl(mylist.get(position).get("ImageURL"));

                return v;
            }
        }//class

and my tourlist.xml file looks like

 <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
            ....
        >

 <ListView android:id="@id/android:list"
           android:layout_width="fill_parent"
           android:layout_height="fill_parent"
           android:background="@drawable/white"
            android:cacheColorHint="#00000000"
           android:layout_weight="1"

           />
</...>
