Gallery와 같은 HorizontalScrollView를 구현하는 방법은 무엇입니까?

Horizontal ScrollView갤러리의 일부 기능 을 구현하고 싶습니다 .

갤러리에서 일정 거리에서 만든 두루마리는 한 쌍으로 정렬됩니다. 즉, 화면에 세 개의 이미지가 표시된 경우 마지막 이미지를 클릭하면 중앙에 정렬됩니다.

HorizontalSCrollView언급 한대로 어떻게 구현 합니까?

내 레이아웃은 다음과 같습니다.

    <HorizontalScrollView
        android:id="@+id/horizontalScrollView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

       <LinearLayout

다음 은 코드가 포함 된 좋은 튜토리얼입니다. 그것이 당신을 위해 작동하는지 알려주세요! 이것은 또한 좋은 튜토리얼입니다.

편집하다

이 예 에서는 다음 줄을 추가하기 만하면됩니다.

gallery.setSelection(1);

어댑터를 갤러리 개체로 설정 한 후 다음 줄입니다.

gallery.setAdapter(new ImageAdapter(this));

업데이트 1

알겠습니다. 문제가 생겼습니다. 이 오픈 소스 라이브러리 가 솔루션입니다. 내 프로젝트 중 하나에도 사용했습니다. 이것이 마침내 문제를 해결할 수 있기를 바랍니다.

업데이트 2 :

이 자습서 를 진행하는 것이 좋습니다 . 당신은 아이디어를 얻을 수 있습니다. 나는 당신의 문제가 있다고 생각합니다, 당신 은 snap과 함께 수평 스크롤 뷰 를 원합니다 . Google 또는 여기에서 해당 키워드로 검색을 시도하면 솔루션을 얻을 수 있습니다.

Horizontal Variable ListView 와 비슷한 것을 구현했습니다 . 유일한 단점은 Android 2.3 이상에서만 작동한다는 것입니다.

이 라이브러리를 사용하는 것은 해당 어댑터로 ListView를 구현하는 것만 큼 간단합니다. 라이브러리는 또한 예제를 제공합니다

나는 수평 만든 목록보기 의 모든 행에 ListView를 사용하면 다음을 수행 할 수 있습니다 하나의 원하는 경우

여기에 그냥 수평 목록 보기 동영상의 썸네일 이렇게

아이디어는 HorizontalscrollView 의 LinearLayout 자식에 ImageView 를 지속적으로 추가 하는 것입니다.

HorizontalListView에 대한 내 XML

<HorizontalScrollView
    android:id="@+id/horizontalScrollView"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_below="@+id/linearLayoutTitle"
    android:background="@drawable/shelf"

HorizontalScrollView를 사용하여 수평 스크롤을 구현할 수 있습니다.

암호

<HorizontalScrollView
android:id="@+id/hsv"
android:layout_width="fill_parent"
android:layout_height="100dp"
 android:layout_weight="0"
android:fillViewport="true"
android:measureAllChildren="false"
android:scrollbars="none" >
<LinearLayout
    android:id="@+id/innerLay"
    android:layout_width="wrap_content"
    android:layout_height="100dp"
    android:gravity="center_vertical"
    android:orientation="horizontal" >
    </LinearLayout>
    </HorizontalScrollView>

Featured.xml :

<?xml version="1.0" encoding="utf-8"?>
   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="160dp"
   android:layout_margin="4dp"
android:layout_height="match_parent"
android:orientation="vertical" >

      <RelativeLayout 
android:layout_width="fill_parent"
android:layout_height="fill_parent" 
>

<ProgressBar                
    android:layout_width="15dip"       
    android:layout_height="15dip"
    android:id="@+id/progress" 
    android:layout_centerInParent="true"
    />

<ImageView
    android:id="@+id/image"       
    android:layout_width="fill_parent"       
    android:layout_height="fill_parent"
    android:background="#20000000"
    />

<TextView
    android:id="@+id/textView1"
    android:layout_width="fill_parent"
    android:layout_height="30dp"
    android:layout_alignParentBottom="true"
    android:layout_alignParentRight="true"
    android:gravity="center"
    android:textColor="#000000"
    android:background="#ffffff"
    android:text="Image Text" />

      </RelativeLayout>
     </LinearLayout>

자바 코드 :

 LayoutInflater inflater;

    inflater=getLayoutInflater();
    LinearLayout inLay=(LinearLayout) findViewById(R.id.innerLay);

    for(int x=0;x<10;x++)
    {
        inLay.addView(getView(x));
    }




 View getView(final int x)
{
   View rootView = inflater.inflate( R.layout.featured_item,null);

   ImageView image = (ImageView) rootView.findViewById(R.id.image);

   //Thease Two Line is sufficient my dear to implement lazyLoading
   AQuery aq = new AQuery(rootView);
   String url="http://farm6.static.flickr.com/5035/5802797131_a729dac808_s.jpg";
   aq.id(image).progress(R.id.progress).image(url, true, true, 0, R.drawable.placeholder1);
   image.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
     Toast.makeText(PhotoActivity.this, "Click Here Postion "+x,     

         Toast.LENGTH_LONG).show();
        }
    });
   return rootView;
       }
