Android(安卓)高仿微信发朋友圈浏览图片效果

最近一直在高仿微信、高仿微信，今天小编再给大家分享一个仿微信发朋友圈浏览图片的效果....

好了，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 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     * by Hankkin at:2015-11-22 23:21:28     */    private void initData(){        contentBeans = new ArrayList();        ArrayList imgUrls1 = new ArrayList();        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 imgUrls2 = new ArrayList();        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 imgUrls3 = new ArrayList();        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);    }    /**     * 初始化组件     * by Hankkin at:2015-11-22 23:21:44     */    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 data;    public MyAdapter(Context context, List 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 * Created by Hankkin on 15/11/22. */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 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 fileList;        public ImagePagerAdapter(FragmentManager fm, ArrayList 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 * Created by Hankkin on 15/11/22. */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);    }

这个效果就很容易实现了，揣摩别人的APP很容易，但是我们要试着去实现别人的APP，生命在于折腾，折腾吧，亲们…..
最后小编把源码上传到了Github上，宝贝们，star吧
