Android——学习笔记

1、URL装Bitmap

public void url2Bitmap(String url){

   Bitmap bitmap = null;
   URLConnection connection ;
   InputStream is ;
   try {
   　　connection = new URL(url).openConnection();i
　　　　is = connection.getInputStream();
       //为了更清楚的看到加载图片的等待操作,将线程休眠3秒钟.
       Thread.sleep(3000);
       BufferedInputStream bis = new BufferedInputStream(is);
       //通过decodeStream方法解析输入流
       bitmap = BitmapFactory.decodeStream(bis);
       is.close();
       bis.close();
       } catch (IOException e) {
       　　e.printStackTrace();
       } catch (InterruptedException e) {
       　　e.printStackTrace();
       }
       return bitmap;
}

2、EditView 默认不弹出软键盘

android:focusable="true"
android:focusableInTouchMode="true"
