Question

如果我想要滚动视图中的图像（动态地）...

怎么办？

这是秘密......

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


    <LinearLayout
            android:id="@+id/li"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10dp"
            android:layout_marginRight="20dp"
            android:layout_marginTop="10dp"
            android:isScrollContainer="true"
            android:orientation="horizontal"
            android:visibility="gone" />
        </HorizontalScrollView>

（不适合专辑查看器）

Answer 1

void setThumbviewImages(int position)
    {
//set margin between two images.

        LayoutParams params = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
        params.setMargins(0, 0, 5, 0);

//universal image loader 
options1 = new DisplayImageOptions.Builder()
.bitmapConfig(Bitmap.Config.ARGB_8888)
.cacheInMemory()
.cacheOnDisc()
.resetViewBeforeLoading()
.build();

    int n = arrl_product.size();
    for (int i = 0; i < n; i++)
    {
        // Item item = arrItem.get(i);
        Product p = arrl_product.get(i);
//custom layout for each imageview. which i required
        final View view_lyt = lyt_Inflater.inflate(R.layout.lyt_com_thumb_img, null);
        final ImageView imageView = (ImageView) view_lyt.findViewById(R.id.non_com_grid_img);

        imageView.setLayoutParams(new RelativeLayout.LayoutParams(img_width, img_height));

        animateFirstListener1 = new Constant.AnimateFirstDisplayListener(new ProgressBar(Act_Comm.this));

        final String image_url = p.arr_images.get(0).image_method;
        imageView.setTag(i);

        imageLoader1.displayImage(image_url, imageView, options1, animateFirstListener1);
        imageView.setOnClickListener(new OnClickListener()
        {

            @Override
            public void onClick(View v)
            {
            }
        });
        lin_thumb.addView(view_lyt, params);
    }

}

我的XML文件

<HorizontalScrollView
                    android:id="@+id/com_iview_horizontalScrollView1"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:padding="5dp"
                    android:visibility="visible" >

                    <LinearLayout
                        android:id="@+id/com_iview_lin_imageview"
                        android:layout_width="0dip"
                        android:layout_height="fill_parent"
                        android:gravity="center_vertical|center_horizontal"
                        android:orientation="horizontal" >
                    </LinearLayout>
                </HorizontalScrollView>

第二个lyt_com_thumb_img.xml布局

＆LT;

?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/thumb_main_Layout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/white"
    android:padding="3dp" >

    <ImageView
        android:id="@+id/non_com_grid_img"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@color/white"
        android:src="@drawable/icon" />

    <ProgressBar
        android:id="@+id/progressBar1"
        style="?android:attr/progressBarStyleSmall"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:visibility="gone" />



</RelativeLayout>
