Android 加载本地图片 和 服务器图片
本地图片可以放到 assets 目录下， 也可以在此目录下新建目录，如?assets/foods/apple.png。
代码取本目录下的图片则如下：
String apple = "foods/apple.png";middle = (ImageView)findViewById(R.id.middle);middle.setImageBitmap(BitmapUtils.getLoacalBitmapByAssets(reservation.this, apple));import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import java.net.HttpURLConnection;import java.net.URL;import android.content.Context;import android.graphics.Bitmap;import android.graphics.BitmapFactory;public class BitmapUtils{ /** * 加载本地图片 * @param url * @return */ public static Bitmap getLoacalBitmapByAssets(Context c, String url) { Bitmap bitmap = null; InputStream in = null; try { in = c.getResources().getAssets().open(url); bitmap = BitmapFactory.decodeStream(in); } catch (IOException e) { e.printStackTrace(); } finally { closeStream(in, null); } return bitmap; } /** * 从服务器取图片 * @param url * @return */ public static Bitmap getHttpBitmap(String url) { URL myFileUrl = null; Bitmap bitmap = null; InputStream in = null; try { myFileUrl = new URL(url); HttpURLConnection conn = (HttpURLConnection)myFileUrl.openConnection(); conn.setConnectTimeout(0); conn.setDoInput(true); conn.connect(); in = conn.getInputStream(); bitmap = BitmapFactory.decodeStream(in); } catch (IOException e) { e.printStackTrace(); } finally { closeStream(in, null); } return bitmap; } /** * 关闭输入输出流 * @param in * @param out */ public static void closeStream(InputStream in, OutputStream out) { try { if (null != in) { in.close(); } if (null != out) { out.close(); } } catch (IOException e) { e.printStackTrace(); } }}?
