我需要的是一个水平滚动ListView，用作可水平滚动的菜单。
我搜索了一个解决方案并想出了this library。
我正在尝试在it.sephiroth.android.library.widget.AdapterView.OnItemClickListener的{{1}}对象上实施it.sephiroth.android.library.widget.HListView。
我可以将列表填充，但我似乎无法将侦听器附加到该项目。 我已经尝试了2天来解决这个问题，但没有比赛。此功能仍无法使用。所以我转向旧WWW寻求救赎。
这是我的DialogFragment XML fragment_layout.xml ：
DialogFragment这是我的viewitem.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#800000"
android:descendantFocusability="blocksDescendants" >
<it.sephiroth.android.library.widget.HListView
android:id="@+id/hlvPlacesListScrollMenu"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@android:color/transparent"
android:scrollbars="none"
android:divider="@android:color/transparent"
/>
这是我的main_activity_layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#800000"
android:clickable="false"
android:focusable="false"
android:orientation="vertical" >
<ImageButton
android:id="@+id/ibScrollMenuImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#800000"
android:clickable="false"
android:focusable="false"
android:scaleType="centerCrop" />
<TextView
android:id="@+id/tvScrollMenuTitle"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:clickable="false"
android:focusable="false"
android:gravity="center_horizontal"
android:textColor="#f4f4f4" />
</LinearLayout>
非常基本。
My MainActicity是：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/llDialogFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#34f34f"
android:orientation="vertical"
tools:context=".MainActivity" >
</LinearLayout>
Dialogfrgment .java：
package com.example.hscrollviewtest;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;
import android.view.Menu;
public class MainActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
LifeStatsDialogFragment menuFragment = new LifeStatsDialogFragment();
ft.add(R.id.llDialogFragment, menuFragment).commit();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
这是适配器（当我在HorizontalVariableListViewDemo中使用它时可以工作）：
package com.example.hscrollviewtest;
import it.sephiroth.android.library.widget.AdapterView;
import it.sephiroth.android.library.widget.AdapterView.OnItemClickListener;
import it.sephiroth.android.library.widget.HListView;
import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class LifeStatsDialogFragment extends DialogFragment implements
OnItemClickListener {
private HListView scroll;
private View rootView;
private HorizontalScrollMenuAdapter mAdapter;
final String[] IMAGE_TITLE = new String[] { "Home", "Work", "School",
"Sport" };
final int[] MENU_IMAGES = new int[] { R.drawable.ic_circle_home,
R.drawable.ic_circle_work, R.drawable.ic_circle_school,
R.drawable.ic_circle_gym };
public LifeStatsDialogFragment newInstance() {
return new LifeStatsDialogFragment();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
rootView = inflater.inflate(R.layout.fragment_layout, container, false);
mAdapter = new HorizontalScrollMenuAdapter(getActivity(),
R.layout.fragment_layout, R.id.tvScrollMenuTitle, IMAGE_TITLE,
MENU_IMAGES);
scroll = (HListView) rootView
.findViewById(R.id.hlvPlacesListScrollMenu);
scroll.setAdapter(mAdapter);
scroll.invalidate();
scroll.setOnItemClickListener(this);
for (int i = 0; i < scroll.getAdapter().getCount(); i++) {
Log.i(this.getClass().getSimpleName(), "first item in scroll : "
+ scroll.getChildAt(i) + "and its clickable?? "
+ scroll.getAdapter().getItemViewType(i) + "\n");
}
Log.i(this.getClass().getSimpleName(),
"The number of children for HlistView is: "
+ scroll.getParent().toString());
return rootView;
}
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// TODO Auto-generated method stub
}
}
我希望你们中的一个能看到我的盲点。 Thaks

可能你正在实现错误的OnItemClickListener。 尝试使用
public class LifeStatsDialogFragment extends DialogFragment implements
it.sephiroth.android.library.widget.AdapterView.OnItemClickListener {
//...
}

我会尝试两件事：
onItemClick会发生什么？ - 它目前是空的。尝试使用独立的onItemClickListener：
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(getActivity(), "clicked", Toast.LENGTH_SHORT);
}
});
