viewpage滑动查看图片并再有缩略图预览
首先看下效果图，
主要功能分为3大块
一是滑动查看，通过viewpage来实现，方法见 http://www.cnblogs.com/lovemo1314/p/6109312.html
二、点击放大
三、下方的缩略图，横向的listview来完成
点击放大用第三方控件PhotoViewAttacher，支持手指缩放，核心代码
ImageView iv = new ImageView(this); Bitmap bitmap = WebchatAdapter.bitmaps.get(i); iv.setImageBitmap(bitmap); //放大及监听 iv.setScaleType(ImageView.ScaleType.MATRIX); // 这句代码之前必须要现有默认图片来撑开位置 iv.setOnClickListener(this); new PhotoViewAttacher(iv); //NOSON
缩略图采用横向listview, 关于这个控件的资料网上许多地方都有介绍，比如 http://rensanning.iteye.com/blog/2201789
这个控件使用起来很简单，只是把它当作纵向kistview来看就行，需要注意的是，listitem的图片布局必须指定固定的宽高，不然会出现一屏只出现一个缩略图的情况。
首先看横向listview的适配器
public class ThumbnailHorizontalLvAdapter extends MyBaseAdapter<FlagBitmap> { private Context mContext; private LayoutInflater mInflater; private int pre_position; public ThumbnailHorizontalLvAdapter(Context context) { super(); mContext = context; mInflater = LayoutInflater.from(context); } @Override public View getView(final int position, View convertView, ViewGroup parent) { if (convertView == null) { convertView = mInflater.inflate(R.layout.listitem_thumbnail_horizontal, null); } ImageView thumbnailImgView = ViewHolder.getView(convertView, R.id.iv_thumbnail_img); LinearLayout container = ViewHolder.getView(convertView, R.id.ll_item_container); FlagBitmap srcBmp = getItem(position); thumbnailImgView.setScaleType(ImageView.ScaleType.FIT_CENTER); thumbnailImgView.setImageBitmap(srcBmp.getBitmap()); if (srcBmp.isSelected()){ thumbnailImgView.setSelected(true); setViewHeightAndWidth(thumbnailImgView, UnitUtil.dp2Px(mContext,40),UnitUtil.dp2Px(mContext,40)); setPadding(container,UnitUtil.dp2Px(mContext,6), UnitUtil.dp2Px(mContext,6)); }else { thumbnailImgView.setSelected(false); setViewHeightAndWidth(thumbnailImgView, UnitUtil.dp2Px(mContext,30),UnitUtil.dp2Px(mContext,30)); setPadding(container,UnitUtil.dp2Px(mContext,3), UnitUtil.dp2Px(mContext,11)); } return convertView; } public void setSelectImg(int pos) { if (pos != pre_position){ getItem(pos).setSelected(true); getItem(pre_position).setSelected(false); pre_position = pos; notifyDataSetChanged(); } } public void initSelectImgPosition(int pos){ pre_position = pos; } private void setViewHeightAndWidth(View v, float w, float h){ ViewGroup.LayoutParams lp = v.getLayoutParams(); lp.width = (int) w; lp.height = (int) h; v.setLayoutParams(lp); } private void setPadding(View v, float left, float top){ v.setPadding((int)left,(int)top,(int)left,(int)top); } private Bitmap getPropThumnail(Bitmap bm) { // Bitmap bb = BitmapUtil.getRoundedCornerBitmap(b, 100); // int w = mContext.getResources().getDimensionPixelOffset(R.dimen.thumnail_default_width); // int h = mContext.getResources().getDimensionPixelSize(R.dimen.thumnail_default_height); // Bitmap thumBitmap = ThumbnailUtils.extractThumbnail(b, (int) UnitUtil.dp2Px(mContext, 100), // (int) UnitUtil.dp2Px(mContext, 100)); // 获得图片的宽高 int width = bm.getWidth(); int height = bm.getHeight(); // 设置想要的大小 int newWidth = 100; int newHeight = 100; // 计算缩放比例 float scaleWidth = ((float) newWidth) / width; float scaleHeight = ((float) newHeight) / height; float scale = scaleHeight > scaleWidth ? scaleHeight : scaleWidth; // 取得想要缩放的matrix参数 Matrix matrix = new Matrix(); matrix.postScale(scale, scale); // 得到新的图片 Bitmap newbm = Bitmap.createBitmap(bm, 0, 0, width, height, matrix, true); Bitmap thumBitmap = ThumbnailUtils.extractThumbnail(newbm, (int) UnitUtil.dp2Px(mContext, 100), (int) UnitUtil.dp2Px(mContext, 100)); return newbm; } }
MyBaseAdapter.java是我封装的一个适配器的基本模板，在这就不贴出来占空间了，很显然，在上面的代码中我们只重写了getview方法，这才是我们关注的重点，是不是完全与普通的list一样。由于在选中大图后，缩略图要随动更新显示，被选中的图要放大一点，带绿色边框。我这里的思路是通过selector器来实现带绿包边框的效果，而放大的效果则只需把对应的item的imageview宽高设置成比未选中的图片稍大一点，让图片来适配控件。
先来看看listitem的布局，很简单，一个固定宽高的imageview
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/ll_item_container" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal"> <ImageView android:id="@+id/iv_thumbnail_img" android:layout_width="40dp" android:layout_height="40dp" android:padding="2dp" android:background="@drawable/sel_thumbnail_img" android:src="@drawable/ico_customer_service" /> </LinearLayout>
再来看看图片的背景选择器文件
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:drawable="@drawable/draw_thumbnail_sel_bg" android:state_selected="true" /> <item android:drawable="@drawable/draw_thumbnail_unsel_bg" android:state_selected="false" /> </selector>
选中状态的draw_thumbnail_sel_bg.xml
<?xml version="1.0" encoding="utf-8"?> <!-- ~ Copyright (c) 2015. Lorem ipsum dolor sit amet, consectetur adipiscing elit. ~ Morbi non lorem porttitor neque feugiat blandit. Ut vitae ipsum eget quam lacinia accumsan. ~ Etiam sed turpis ac ipsum condimentum fringilla. Maecenas magna. ~ Proin dapibus sapien vel ante. Aliquam erat volutpat. Pellentesque sagittis ligula eget metus. ~ Vestibulum commodo. Ut rhoncus gravida arcu. --> <layer-list xmlns:android="http://schemas.android.com/apk/res/android"> <!-- 连框颜色值 --> <item> <shape> <solid android:color="@color/bar_tint"/> <corners android:radius="5dp"/> <size android:width="40dp" android:height="40dp"></size> </shape> </item> <!-- 主体背景颜色值 --> <item android:bottom="2dp" android:left="2dp" android:right="2dp" android:top="2dp"> <!--边框里面背景颜色 白色--> <shape> <corners android:radius="5dp"/> <solid android:color="@android:color/white"/> </shape> </item> </layer-list>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"> <!-- 连框颜色值 --> <item> <shape> <solid android:color="@color/line_back"/> <corners android:radius="5dp"/> <size android:width="30dp" android:height="30dp"></size> </shape> </item> <!-- 主体背景颜色值 --> <item android:bottom="0dp" android:left="0dp" android:right="0dp" android:top="0dp"> <!--边框里面背景颜色 白色--> <shape> <corners android:radius="5dp"/> <solid android:color="@android:color/white"/> </shape> </item> </layer-list>
最后只要把横向listview与viewpage中的大图关联起来就好了。
//缩略图 thumbnailHorizontalLvAdapter = new ThumbnailHorizontalLvAdapter(this); horizontalListView.setAdapter(thumbnailHorizontalLvAdapter); horizontalListView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { viewPager.setCurrentItem(position); //缩略图点击后同时刷新大图位置 thumbnailHorizontalLvAdapter.setSelectImg(position); } });
再看大图的适配器
public class KnowcognoViewImagePagerAdapter extends PagerAdapter implements ViewPager.OnPageChangeListener { private static final String TAG = "state-viewpage-know"; private Context context; private ViewPager viewPager; private List<ImageView> views; private ThumbnailHorizontalLvAdapter thumbnailImgAdapter; public KnowcognoViewImagePagerAdapter(Context context, List<ImageView> viewpages, ViewPager viewPager, ThumbnailHorizontalLvAdapter thumbnailHorizontalLvAdapter) { this.context = context; this.viewPager = viewPager; thumbnailImgAdapter = thumbnailHorizontalLvAdapter; this.viewPager.addOnPageChangeListener(this); views = viewpages; } @Override public Object instantiateItem(ViewGroup container, int position) { ImageView imageView = (ImageView) views.get(position); container.addView(imageView); return imageView; } @Override public void destroyItem(ViewGroup container, int position, Object object) { container.removeView((View) object); } @Override public int getCount() { return views.size(); } @Override public boolean isViewFromObject(View view, Object object) { return view == object; } @Override public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { } @Override public void onPageSelected(final int position) { } @Override public void onPageScrollStateChanged(int state) { System.err.println("-------state------>" + state); switch (state) { //在滚动完成之后 case ViewPager.SCROLL_STATE_IDLE: System.err.println("-------state-vitem----->" + viewPager.getCurrentItem()); thumbnailImgAdapter.setSelectImg(viewPager.getCurrentItem()); //滑动完，更新缩略图位置 break; } } }
最后看横向listview的控件，这个也可以去网上找
