#服务端和客户端交互
服务器：接收文件，并且把文件，存储到指定目录，对文件进行命名的等操作。
客户端：选定文件，拼接参数，上传到指定服务器上。
#购买服务器（阿里云服务器或者自己搭建服务器）
#搭建服务器（软件服务器）
源码环境：
jre7 tomcat7
1、将.war文件复制到tomcat服务器webapps下，启动服务器即可
2、访问工程路径a即可测试上传
b/s架构 通过浏览器上传
c/s结构 通过Android端上传
上传文件服务地址：

#Android-Universal-Image-Loader在ListView中使用
在使用Image-Loader之前需要在Application里面做初始化
public static void initImageLoader(Context context) {
// This configuration tuning is custom. You can tune every option, you may tune some of them,
// or you can create default configuration by
// ImageLoaderConfiguration.createDefault(this);
// method.
ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context)
//设置当前线程的优先级
.threadPriority(Thread.NORM_PRIORITY - 2)
// 缓存显示不同大小的同一张图片
.denyCacheImageMultipleSizesInMemory()
//将保存的时候的URI名称用MD5 加密
.discCacheFileNameGenerator(new Md5FileNameGenerator())
.tasksProcessingOrder(QueueProcessingType.LIFO)
.writeDebugLogs() // Remove for release app
.build();
// Initialize ImageLoader with configuration.
ImageLoader.getInstance().init(config);
}
1.在适配器中配置信息
protected ImageLoader imageLoader = ImageLoader.getInstance();
DisplayImageOptions options = new DisplayImageOptions.Builder()
.showImageOnLoading(R.drawable.ic_stub)
.showImageForEmptyUri(R.drawable.ic_empty)
.showImageOnFail(R.drawable.ic_error)
.cacheInMemory(true)////设置下载的图片是否缓存在内存中
.cacheOnDisc(true)////设置下载的图片是否缓存在SD卡中
.considerExifParams(true)//是否考虑JPEG图像EXIF参数（旋转，翻转）
.displayer(new RoundedBitmapDisplayer(20))//设置图片圆角
.build();
2.在适配器中的getView中请求图片如下代码：
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
......
//第一个参数是：图片的地址，第二个参数是要绑定的图片，第三个参数处理图片的配置，第四个参数
imageLoader.displayImage(imageUrls[position], holder.image, options, animateFirstListener);
return view;
}
}
3.设置监听animateFirstListener代码如下
class ItemAdapter extends BaseAdapter {
private ImageLoadingListener animateFirstListener = new AnimateFirstDisplayListener();
..............
}
private static class AnimateFirstDisplayListener extends SimpleImageLoadingListener {
static final List<String> displayedImages = Collections.synchronizedList(new LinkedList<String>());
@Override
public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
if (loadedImage != null) {
ImageView imageView = (ImageView) view;
boolean firstDisplay = !displayedImages.contains(imageUri);
if (firstDisplay) {
FadeInBitmapDisplayer.animate(imageView, 500);//显示图片的过程有一个渐变动画
displayedImages.add(imageUri);
}
}
}
}
#Android-Universal-Image-Loader在 GridView中使用
1.设置配置信息
protected ImageLoader imageLoader = ImageLoader.getInstance();
DisplayImageOptions options = new DisplayImageOptions.Builder()
.showImageOnLoading(R.drawable.ic_stub)
.showImageForEmptyUri(R.drawable.ic_empty)
.showImageOnFail(R.drawable.ic_error)
.cacheInMemory(true)
.cacheOnDisc(true)
.considerExifParams(true)
.bitmapConfig(Bitmap.Config.RGB_565)
.build();
2.在适配器的getView中请求网络图片，请求图片的时候，带有加载进度，代码如下，
@Override
public View getView(int position, View convertView, ViewGroup parent) {
final ViewHolder holder;
View view = convertView;
if (view == null) {
view = getLayoutInflater().inflate(R.layout.item_grid_image, parent, false);
holder = new ViewHolder();
assert view != null;
holder.imageView = (ImageView) view.findViewById(R.id.image);
holder.progressBar = (ProgressBar) view.findViewById(R.id.progress);
view.setTag(holder);
} else {
holder = (ViewHolder) view.getTag();
}
imageLoader.displayImage(imageUrls[position], holder.imageView, options, new SimpleImageLoadingListener() {
@Override
public void onLoadingStarted(String imageUri, View view) {
holder.progressBar.setProgress(0);
holder.progressBar.setVisibility(View.VISIBLE);
}
@Override
public void onLoadingFailed(String imageUri, View view,
FailReason failReason) {
holder.progressBar.setVisibility(View.GONE);
}
@Override
public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
holder.progressBar.setVisibility(View.GONE);
}
}, new ImageLoadingProgressListener() {
@Override
public void onProgressUpdate(String imageUri, View view, int current,
int total) {
holder.progressBar.setProgress(Math.round(100.0f * current / total));
}
}
);
return view;
}
#Picasso 的加载图片库的使用
1.把jar拷贝到项目下lib里
下载jar包地址
http://square.github.io/picasso/#download
2.单独请求某一张图片的用法
Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").into(imageView);
３.在ListView中适配器的getView中用法
@Override
public View getView(int position, View convertView, ViewGroup parent) {
final ViewHolder viewHolder;
if (convertView == null) {
convertView = View.inflate(context, R.layout.image_items, null);
viewHolder = new ViewHolder();
viewHolder.imageview = (ImageView) convertView.findViewById(R.id.imageview);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
viewHolder.imageview.setImageResource(R.drawable.empty_photo);
//得到数据
String imageurl = imageThumbUrls[position];
//
Picasso.with(context).load(imageurl).into(viewHolder.imageview);
return convertView;
}
#Glide 的加载图片库的使用
1.需要在联网的情况下，在build.gradle文件中配置
compile ‘com.github.bumptech.glide:glide:3.7.0‘
compile ‘com.android.support:support-v4:22.2.1‘
2.请求单张图片代码如下：
Glide.with(context)
.load("http://inthecheesefactory.com/uploads/source/glidepicasso/cover.jpg")
.into(ivImg);
3.在使用Lisview的适配器中，getView里使用，代码如下：
@Override
public View getView(int position, View convertView, ViewGroup parent) {
final ViewHolder viewHolder;
if (convertView == null) {
convertView = View.inflate(context, R.layout.image_items, null);
viewHolder = new ViewHolder();
viewHolder.imageview = (ImageView) convertView.findViewById(R.id.imageview);
convertView.setTag(viewHolder);
} else {
viewHolder = (ViewHolder) convertView.getTag();
}
viewHolder.imageview.setImageResource(R.drawable.empty_photo);
//得到数据
String imageurl = imageThumbUrls[position];
Glide
.with(context)
.load(imageurl)
.centerCrop()
.placeholder(R.drawable.empty_photo)
.crossFade()
.into(viewHolder.imageview);
return convertView;
}
#Android-gif-drawable的使用
1.联网框架和 添加Android-gif-drawable 的jar包
compile files(‘libs/android-async-http-1.4.5.jar‘)
compile files(‘libs/classes.jar‘)
2.加载单张gif动画图片
asyncHttpClient = new AsyncHttpClient();
asyncHttpClient
.get("http://cdn.duitang.com/uploads/item/201311/20/20131120213622_mJCUy.thumb.600_0.gif",
new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int arg0, Header[] arg1,
byte[] arg2) {
// TODO Auto-generated method stub
GifDrawable drawable = null;
try {
drawable = new GifDrawable(arg2);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
network_gifimageview
.setBackground(drawable);
dialog.dismiss();
}
@Override
public void onFailure(int arg0, Header[] arg1,
byte[] arg2, Throwable arg3) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(),
"加载网络图片出错", Toast.LENGTH_SHORT).show();
dialog.dismiss();
}
});
3.用Android-gif-drawabl在ListView 中加载gif动画
@Override
public View getView(int position, View convertView, ViewGroup parent) {
final GifImageView imageView;
if (convertView == null) {
imageView = new GifImageView(context);
imageView.setScaleType(ImageView.ScaleType.FIT_XY);
imageView.setPadding(10, 10, 10, 10);
int size = AbsListView.LayoutParams.WRAP_CONTENT;
AbsListView.LayoutParams layoutParams = new GridView.LayoutParams(size, size);
imageView.setLayoutParams(layoutParams);
} else {
imageView = (GifImageView) convertView;
}
asyncHttpClient
.get(imageUrls.get(position),
new AsyncHttpResponseHandler() {
@Override
public void onSuccess(int i, Header[] headers, byte[] bytes) {
try {
GifDrawable drawable = new GifDrawable(bytes);
imageView
.setBackground(drawable);
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public void onFailure(int i, Header[] headers, byte[] bytes, Throwable throwable) {
System.out.println(throwable.getMessage());
}
});
return imageView;
}
#PhotoView的使用-单张图片
作用，加载图片的时候，可以缩放图片
1.关联photoView的库
compile ‘com.nostra13.universalimageloader:universal-image-loader:1.9.3‘
compile project(‘:PhotoView_library‘)
2.在布局中定义PhotoView
<uk.co.senab.photoview.PhotoView
android:id="@+id/iv_photo"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
3.实例化控件并且设置相关的监听
ImageView mImageView = (ImageView) findViewById(R.id.iv_photo);
mCurrMatrixTv = (TextView) findViewById(R.id.tv_current_matrix);
Drawable bitmap = getResources().getDrawable(R.drawable.wallpaper);
mImageView.setImageDrawable(bitmap);
// The MAGIC happens here!
mAttacher = new PhotoViewAttacher(mImageView);
// Lets attach some listeners, not required though!
mAttacher.setOnMatrixChangeListener(new MatrixChangeListener());
mAttacher.setOnPhotoTapListener(new PhotoTapListener());
private class MatrixChangeListener implements OnMatrixChangedListener {
@Override
public void onMatrixChanged(RectF rect) {
mCurrMatrixTv.setText(rect.toString());
}
}
private class PhotoTapListener implements OnPhotoTapListener {
@Override
public void onPhotoTap(View view, float x, float y) {
float xPercentage = x * 100f;
float yPercentage = y * 100f;
showToast(String.format(PHOTO_TAP_TOAST_STRING, xPercentage, yPercentage, view == null ? 0 : view.getId()));
}
}
#PhotoView的使用-ViewPager中使用
应用场景：类似于空间图片浏览效果
1.在布局文件中定义HackyViewPager类，它继承ViewPager的
<uk.co.senab.photoview.sample.HackyViewPager xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
2.设置适配器
mViewPager.setAdapter(new SamplePagerAdapter());
3.适配器具体代码如下：
static class SamplePagerAdapter extends PagerAdapter {
private static final int[] sDrawables = { R.drawable.wallpaper, R.drawable.wallpaper, R.drawable.wallpaper,
R.drawable.wallpaper, R.drawable.wallpaper, R.drawable.wallpaper };
@Override
public int getCount() {
return sDrawables.length;
}
@Override
public View instantiateItem(ViewGroup container, int position) {
PhotoView photoView = new PhotoView(container.getContext());
photoView.setImageResource(sDrawables[position]);
// Now just add PhotoView to ViewPager and return it
container.addView(photoView, LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
return photoView;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView((View) object);
}
@Override
public boolean isViewFromObject(View view, Object object) {
return view == object;
}
}
