我有一个自定义的baseadapter的列表视图，代码为类和适配器如下的ListView，OnItemClickListener无响应
public class LazyAdapter extends BaseAdapter {
private Activity activity;
private ArrayList<HashMap<String, String>> data;
private static LayoutInflater inflater=null;
public ImageLoader imageLoader;
public LazyAdapter(Activity a, ArrayList<HashMap<String, String>> d) {
activity = a;
data=d;
inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
imageLoader=new ImageLoader(activity.getApplicationContext());
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return data.size();
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View vi=convertView;
if(convertView==null)
vi = inflater.inflate(R.layout.custom_row_view1, null);
TextView title = (TextView)vi.findViewById(R.id.linkname); // merchnts name
TextView artist = (TextView)vi.findViewById(R.id.imagename); // address
//TextView duration = (TextView)vi.findViewById(R.id); // distance
// ImageView thumb_image=(ImageView)vi.findViewById(R.id.mClogo); // logo
HashMap<String, String> jsn = new HashMap<String, String>();
jsn = data.get(position);
// Setting all values in listview
title.setText(jsn.get(Second.Li_nk));
artist.setText(jsn.get(Second.Image_name));
//duration.setText(song.get(CustomizedListView.KEY_DURATION));
//imageLoader.DisplayImage(jsn.get(NearBy.KEY_THUMB_URL), thumb_image);
return vi;
}
}
和类实现其计算方法如下
HashMap<String,String> map=new HashMap<String,String>();
map.put("Id",String.valueOf(i));
map.put(Li_nk,cutsec);
map.put(Image_name,j4.getString("image_name"));
mylist.add(map);
}
}
catch(JSONException e){
Log.e("loG_tag","Error parsing"+e.toString());
}
list=(ListView)findViewById(R.id.lv1);
list.setOnItemClickListener(new AdapterView.OnItemClickListener(){
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(getApplicationContext(),
"Click ListItem Number " + position, Toast.LENGTH_LONG)
.show();
}
});
LazyAdapter adapter = new LazyAdapter(this,mylist);
list.setAdapter(adapter);
list.setItemsCanFocus(false);
}
包含列表视图的布局是
<?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:background="#FFFFFF"
android:orientation="vertical" >
<ImageView
android:id="@+id/imageView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:src="@drawable/zsm" />
<ListView
android:id="@+id/lv1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/imageView1"
android:clickable="True"
>
</ListView>
</RelativeLayout>
和用于为l的自定义布局的代码ist is
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<RelativeLayout
android:id="@+id/relativeLayout1"
android:layout_width="fill_parent"
android:layout_height="70dp"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:clickable="True"
android:focusable="false"
android:background="@drawable/list_selector"
>
<ImageView
android:id="@+id/imageView1"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:layout_marginLeft="21dp"
android:focusable="false"
android:src="@drawable/merchntlogotitle" />
<TextView
android:id="@+id/imagename"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="@+id/imageView1"
android:layout_marginLeft="15dp"
android:layout_toRightOf="@+id/imageView1"
android:clickable="false"
android:focusable="false"
android:text="Small Text"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textColor="#000000" />
<TextView
android:id="@+id/linkname"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@+id/imagename"
android:layout_alignLeft="@+id/imagename"
android:clickable="false"
android:focusable="false"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="#000000" />
</RelativeLayout>
</RelativeLayout>
现在设置onitemclick监听器没有回应，我在做什么错？ 我已经阅读了大量的关于设置焦点假和其他的xamples，我做错了什么？ 任何帮助将大大升级...
** list.setItemsCanFocus（false）; **是此行所必需的。 – ngesh 2012-04-16 08:41:13
