1、最常用ImageLoader
//调用方法ImageLoader.getInstance().displayImage(“url”,mImg_photo, imageOptions);//设置图片属性：下载时的图片，下载失败的图片，，是否圆角DisplayImageOptions imageOptions = new DisplayImageOptions.Builder().cacheInMemory(true).cacheOnDisc(true).showImageOnLoading(R.drawable.default_loading)// 加载开始默认的图片.showImageForEmptyUri(R.drawable.default_loading) // url爲空會显示该图片，自己放在drawable里面的.showImageOnFail(R.drawable.default_loading)// 加载图片出现问题，会显示该图片.imageScaleType(ImageScaleType.IN_SAMPLE_INT).bitmapConfig(Bitmap.Config.RGB_565).build();package com.example.another;import android.annotation.TargetApi;import android.app.Application;import android.content.Context;import android.os.Build;import com.nostra13.universalimageloader.cache.disc.naming.Md5FileNameGenerator;import com.nostra13.universalimageloader.core.ImageLoader;import com.nostra13.universalimageloader.core.ImageLoaderConfiguration;import com.nostra13.universalimageloader.core.assist.QueueProcessingType;/** * @author Sergey Tarasevich (nostra13[at]gmail[dot]com) */{@TargetApi(Build.VERSION_CODES.GINGERBREAD)@SuppressWarnings(“unused”)() {super.onCreate();initImageLoader(getApplicationContext());}(Context context) {ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context).threadPriority(Thread.NORM_PRIORITY – 2).denyCacheImageMultipleSizesInMemory().diskCacheFileNameGenerator(new Md5FileNameGenerator()).tasksProcessingOrder(QueueProcessingType.LIFO).writeDebugLogs() // Remove for release app.build();// Initialize ImageLoader with configuration.ImageLoader.getInstance().init(config);}}
2、AsyncTask下载
//开启图片加载ImageAsyncTask asyncTask = new ImageAsyncTask();asyncTask.execute(“url”); <String, Void, Bitmap>{private Bitmap bitmap;@Overrideprotected Bitmap doInBackground(String… params){InputStream is = null;try{URL url = new URL(params[0]);URLConnection openConnection = url.openConnection();is = openConnection.getInputStream();bitmap = BitmapFactory.decodeStream(is);if (bitmap != null){hadImage.put(params[0], bitmap);}}catch (MalformedURLException e){// TODO Auto-generated catch blocke.printStackTrace();}catch (IOException e){// TODO Auto-generated catch blocke.printStackTrace();}finally{if (is != null){try{is.close();}catch (IOException e){// TODO Auto-generated catch blocke.printStackTrace();}}}return bitmap;}@Overrideprotected void onPostExecute(Bitmap result){// 下载完显示imageView.setImageBitmap(result);super.onPostExecute(result);}}
找一个让心里安静和干净的地方，自己变得跟水晶一般透明，
