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"
