先看一下效果吧：

下面就来说一下具体怎么实现的：

实现思路

1.首先我们要获取数据源，数据源就是我们的每条说说（包括姓名、标题、图片数组） 2.自定义适配器（ListView嵌套着GridView） 3.图片点击浏览图片（Fragment+ViewPager）

具体实现

1.初始化数据源，设置适配器，看一下代码：

public class MyActivity extends Activity { /*图片显示列表*/ private ListView listView; /*图片URL数组*/ private List<ContentBean> contentBeans; /*说说适配器*/ private MyAdapter adapter; /** * Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); initData(); initViews(); } /** * 初始化数据 */ private void initData(){ contentBeans = new ArrayList<ContentBean>(); ArrayList<String> imgUrls1 = new ArrayList<String>(); imgUrls1.add("http://7xojuc.com1.z0.glb.clouddn.com/110H2E40-6.jpg?attname=&e=1448288962&token=KDsCqUAWz3P-YT6In6oPnT56Eh2cig4zgQd12SJ_:AlTjfYD9SBFOdB4jmmZuKXAMOp8"); ContentBean cb1 = new ContentBean(1,"java","Sun Microsystems",imgUrls1); contentBeans.add(cb1); ArrayList<String> imgUrls2 = new ArrayList<String>(); imgUrls2.add("http://7xojuc.com1.z0.glb.clouddn.com/110H2E40-6.jpg?attname=&e=1448288962&token=KDsCqUAWz3P-YT6In6oPnT56Eh2cig4zgQd12SJ_:AlTjfYD9SBFOdB4jmmZuKXAMOp8"); imgUrls2.add("http://7xojuc.com1.z0.glb.clouddn.com/110H2E40-6.jpg?attname=&e=1448288962&token=KDsCqUAWz3P-YT6In6oPnT56Eh2cig4zgQd12SJ_:AlTjfYD9SBFOdB4jmmZuKXAMOp8"); imgUrls2.add("http://7xojuc.com1.z0.glb.clouddn.com/110H2E40-6.jpg?attname=&e=1448288962&token=KDsCqUAWz3P-YT6In6oPnT56Eh2cig4zgQd12SJ_:AlTjfYD9SBFOdB4jmmZuKXAMOp8"); ContentBean cb2 = new ContentBean(2,"OC","Stepstone",imgUrls2); contentBeans.add(cb2); ArrayList<String> imgUrls3 = new ArrayList<String>(); imgUrls3.add("http://7xojuc.com1.z0.glb.clouddn.com/110H2E40-6.jpg?attname=&e=1448288962&token=KDsCqUAWz3P-YT6In6oPnT56Eh2cig4zgQd12SJ_:AlTjfYD9SBFOdB4jmmZuKXAMOp8"); imgUrls3.add("http://7xojuc.com1.z0.glb.clouddn.com/110H2E40-6.jpg?attname=&e=1448288962&token=KDsCqUAWz3P-YT6In6oPnT56Eh2cig4zgQd12SJ_:AlTjfYD9SBFOdB4jmmZuKXAMOp8"); imgUrls3.add("http://7xojuc.com1.z0.glb.clouddn.com/110H2E40-6.jpg?attname=&e=1448288962&token=KDsCqUAWz3P-YT6In6oPnT56Eh2cig4zgQd12SJ_:AlTjfYD9SBFOdB4jmmZuKXAMOp8"); imgUrls3.add("http://7xojuc.com1.z0.glb.clouddn.com/110H2E40-6.jpg?attname=&e=1448288962&token=KDsCqUAWz3P-YT6In6oPnT56Eh2cig4zgQd12SJ_:AlTjfYD9SBFOdB4jmmZuKXAMOp8"); imgUrls3.add("http://7xojuc.com1.z0.glb.clouddn.com/110H2E40-6.jpg?attname=&e=1448288962&token=KDsCqUAWz3P-YT6In6oPnT56Eh2cig4zgQd12SJ_:AlTjfYD9SBFOdB4jmmZuKXAMOp8"); imgUrls3.add("http://7xojuc.com1.z0.glb.clouddn.com/110H2E40-6.jpg?attname=&e=1448288962&token=KDsCqUAWz3P-YT6In6oPnT56Eh2cig4zgQd12SJ_:AlTjfYD9SBFOdB4jmmZuKXAMOp8"); imgUrls3.add("http://7xojuc.com1.z0.glb.clouddn.com/110H2E40-6.jpg?attname=&e=1448288962&token=KDsCqUAWz3P-YT6In6oPnT56Eh2cig4zgQd12SJ_:AlTjfYD9SBFOdB4jmmZuKXAMOp8"); imgUrls3.add("http://7xojuc.com1.z0.glb.clouddn.com/110H2E40-6.jpg?attname=&e=1448288962&token=KDsCqUAWz3P-YT6In6oPnT56Eh2cig4zgQd12SJ_:AlTjfYD9SBFOdB4jmmZuKXAMOp8"); imgUrls3.add("http://7xojuc.com1.z0.glb.clouddn.com/110H2E40-6.jpg?attname=&e=1448288962&token=KDsCqUAWz3P-YT6In6oPnT56Eh2cig4zgQd12SJ_:AlTjfYD9SBFOdB4jmmZuKXAMOp8"); ContentBean cb3 = new ContentBean(3,"python","Guido van Rossum",imgUrls3); contentBeans.add(cb3); } private void initViews(){ listView = (ListView) findViewById(R.id.lv_my); adapter = new MyAdapter(MyActivity.this,contentBeans); listView.setAdapter(adapter); } }

这里面的图片是我上传到七牛的网络图片，加载图片是用ImageLoader,下面也有具体的ImageLoader配置。

2.看一下适配器内容

在说说列表适配器中去设置图片的适配器，图片的GridView是重写了一个不能滑动的GridView，重写一下OnMeasure();

public class MyAdapter extends BaseAdapter { private Context context; private List<ContentBean> data; public MyAdapter(Context context, List<ContentBean> data) { this.context = context; this.data = data; } @Override public int getCount() { return data.size(); } @Override public Object getItem(int i) { return data.get(i); } @Override public long getItemId(int i) { return i; } @Override public View getView(int i, View view, ViewGroup viewGroup) { ViewHolder holder; if (view == null) { holder = new ViewHolder(); view = View.inflate(context, R.layout.item, null); holder.gridView = (NoScrollGridView) view.findViewById(R.id.gridview); holder.tvName = (TextView) view.findViewById(R.id.tv_name); holder.tvTitle = (TextView) view.findViewById(R.id.tv_title); view.setTag(holder); } else { holder = (ViewHolder) view.getTag(); } final ContentBean bean = data.get(i); holder.tvName.setText(bean.getName()); holder.tvTitle.setText(bean.getTitle()); if (data != null && data.size() > 0) { holder.gridView.setAdapter(new ImageGridAdapter(context, bean.getImgUrls())); } /** * 图片列表点击事件 */ holder.gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) { Intent intent = new Intent(context, ImagePagerActivity.class); intent.putExtra(ImagePagerActivity.EXTRA_IMAGE_URLS, (Serializable) bean.getImgUrls()); intent.putExtra(ImagePagerActivity.EXTRA_IMAGE_INDEX, i); context.startActivity(intent); } }); return view; } class ViewHolder { TextView tvName, tvTitle; NoScrollGridView gridView; } }

3.然后就是图片浏览，这个网上也有好多的Demo，也有详细的讲解，直接拽过来用就可以了，下面的图片数量是监听setOnPageChangeListener（）来改变下面的图片索引值

/** * 图片查看器 */ public class ImagePagerActivity extends FragmentActivity { private static final String STATE_POSITION = "STATE_POSITION"; public static final String EXTRA_IMAGE_INDEX = "image_index"; public static final String EXTRA_IMAGE_URLS = "image_urls"; private HackyViewPager mPager; private int pagerPosition; private TextView indicator; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.image_detail_pager); pagerPosition = getIntent().getIntExtra(EXTRA_IMAGE_INDEX, 0); ArrayList<String> urls = getIntent().getStringArrayListExtra(EXTRA_IMAGE_URLS); mPager = (HackyViewPager) findViewById(R.id.pager); ImagePagerAdapter mAdapter = new ImagePagerAdapter(getSupportFragmentManager(), urls); mPager.setAdapter(mAdapter); indicator = (TextView) findViewById(R.id.indicator); CharSequence text = getString(R.string.viewpager_indicator, 1, mPager.getAdapter().getCount()); indicator.setText(text); // 更新下标 mPager.setOnPageChangeListener(new OnPageChangeListener() { @Override public void onPageScrollStateChanged(int arg0) { } @Override public void onPageScrolled(int arg0, float arg1, int arg2) { } @Override public void onPageSelected(int arg0) { CharSequence text = getString(R.string.viewpager_indicator, arg0 + 1, mPager.getAdapter().getCount()); indicator.setText(text); } }); if (savedInstanceState != null) { pagerPosition = savedInstanceState.getInt(STATE_POSITION); } mPager.setCurrentItem(pagerPosition); } @Override public void onSaveInstanceState(Bundle outState) { outState.putInt(STATE_POSITION, mPager.getCurrentItem()); } private class ImagePagerAdapter extends FragmentStatePagerAdapter { public ArrayList<String> fileList; public ImagePagerAdapter(FragmentManager fm, ArrayList<String> fileList) { super(fm); this.fileList = fileList; } @Override public int getCount() { return fileList == null ? 0 : fileList.size(); } @Override public Fragment getItem(int position) { String url = fileList.get(position); return ImageDetailFragment.newInstance(url); } } }

图片Fragment的详细界面，里面有长按点击事件，和图片加载的状态

package com.hankkin.WeiXinLookImgsDemo.activty; import android.graphics.Bitmap; import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.ImageView; import android.widget.ProgressBar; import android.widget.Toast; import com.hankkin.WeiXinLookImgsDemo.R; import com.nostra13.universalimageloader.core.ImageLoader; import com.nostra13.universalimageloader.core.assist.FailReason; import com.nostra13.universalimageloader.core.listener.SimpleImageLoadingListener; import com.others.PhotoViewAttacher; /** * 单张图片显示Fragment */ public class ImageDetailFragment extends Fragment { private String mImageUrl; private ImageView mImageView; private ProgressBar progressBar; private PhotoViewAttacher mAttacher; public static ImageDetailFragment newInstance(String imageUrl) { final ImageDetailFragment f = new ImageDetailFragment(); final Bundle args = new Bundle(); args.putString("url", imageUrl); f.setArguments(args); return f; } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mImageUrl = getArguments() != null ? getArguments().getString("url") : null; } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { final View v = inflater.inflate(R.layout.image_detail_fragment, container, false); mImageView = (ImageView) v.findViewById(R.id.image); mAttacher = new PhotoViewAttacher(mImageView); mAttacher.setOnPhotoTapListener(new PhotoViewAttacher.OnPhotoTapListener() { @Override public void onPhotoTap(View arg0, float arg1, float arg2) { getActivity().finish(); } }); mAttacher.setOnLongClickListener(new View.OnLongClickListener() { @Override public boolean onLongClick(View view) { Toast.makeText(getActivity().getApplicationContext(),"保存",Toast.LENGTH_SHORT).show(); return false; } }); progressBar = (ProgressBar) v.findViewById(R.id.loading); return v; } @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); ImageLoader.getInstance().displayImage(mImageUrl, mImageView, new SimpleImageLoadingListener() { @Override public void onLoadingStarted(String imageUri, View view) { progressBar.setVisibility(View.VISIBLE); } @Override public void onLoadingFailed(String imageUri, View view, FailReason failReason) { String message = null; switch (failReason.getType()) { case IO_ERROR: message = "下载错误"; break; case DECODING_ERROR: message = "图片无法显示"; break; case NETWORK_DENIED: message = "网络有问题，无法下载"; break; case OUT_OF_MEMORY: message = "图片太大无法显示"; break; case UNKNOWN: message = "未知的错误"; break; } Toast.makeText(getActivity(), message, Toast.LENGTH_SHORT).show(); progressBar.setVisibility(View.GONE); } @Override public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) { progressBar.setVisibility(View.GONE); mAttacher.update(); } }); } }

忘了ImageLoader的初始化工作了，给大家加上吧，我写到Application里了。

private MyApplication context; @Override public void onCreate() { super.onCreate(); context = this; initImageLoader(context); } /** * 初始化Imageloader * by Hankkin at:2015-11-22 23:20:29 * @param context */ public static void initImageLoader(Context context){ DisplayImageOptions options = new DisplayImageOptions.Builder() .showImageOnLoading(R.drawable.ic_launcher) .showImageOnFail(R.drawable.ic_launcher) .resetViewBeforeLoading(false) // default .delayBeforeLoading(0) .cacheInMemory(true) // default .cacheOnDisk(true) // default .considerExifParams(true) // default .imageScaleType(ImageScaleType.IN_SAMPLE_POWER_OF_2) // default .bitmapConfig(Bitmap.Config.ARGB_8888) // default .displayer(new SimpleBitmapDisplayer()) // default .handler(new Handler()) // default .build(); File picPath = new File(Environment.getExternalStorageDirectory().getPath() + File.separator + "weixinlookimgdemo" + File.separator + "files"); ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context) .memoryCacheExtraOptions(480, 800) // default = device screen dimensions .diskCacheExtraOptions(480, 800, null) .threadPoolSize(3) // default .threadPriority(Thread.NORM_PRIORITY - 1) // default .tasksProcessingOrder(QueueProcessingType.FIFO) // default .denyCacheImageMultipleSizesInMemory() .memoryCache(new LruMemoryCache(2 * 1024 * 1024)) .memoryCacheSize(2 * 1024 * 1024) .memoryCacheSizePercentage(13) // default .diskCache(new UnlimitedDiscCache(picPath)) // default .diskCacheSize(50 * 1024 * 1024) .diskCacheFileCount(1000) .diskCacheFileNameGenerator(new HashCodeFileNameGenerator()) // default .imageDownloader(new BaseImageDownloader(context)) // default .imageDecoder(new BaseImageDecoder(true)) // default .defaultDisplayImageOptions(options) // default .writeDebugLogs() .build(); // Initialize ImageLoader with configuration. ImageLoader.getInstance().init(config); }
