我使用下面的代码将图像保存在SD卡中,但我继续将此问题置于异常之下
private void SaveImage(Bitmap finalBitmap,String filename) { String root = Environment.getExternalStorageDirectory().toString(); File myDir = new File(root + "/saved_images"); myDir.mkdirs(); String fname = filename; File file = new File (myDir,fname); if (file.exists ()) file.delete (); try { FileOutputStream out = new FileOutputStream(file); finalBitmap.compress(Bitmap.CompressFormat.JPEG,90,out); out.flush(); out.close(); } catch (Exception e) { e.printStackTrace(); } }
我错过了什么吗?

在您不创建目录时修改代码.
private void SaveImage(Bitmap finalBitmap,String filename) {
String root = Environment.getExternalStorageDirectory().toString();
File myDir = new File(root + "/saved_images");
myDir.mkdirs();
String fname = filename;
File file = new File (myDir,fname);
if (file.exists ()) file.delete ();
file.createNewFile();
try {
FileOutputStream out = new FileOutputStream(file);
finalBitmap.compress(Bitmap.CompressFormat.JPEG,out);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
private void SaveImage(Bitmap finalBitmap,String filename) { String root = Environment.getExternalStorageDirectory().toString(); File myDir = new File(root + "/saved_images"); myDir.mkdirs(); String fname = filename; File file = new File (myDir,fname); if (file.exists ()) file.delete (); file.createNewFile(); try { FileOutputStream out = new FileOutputStream(file); finalBitmap.compress(Bitmap.CompressFormat.JPEG,out); out.flush(); out.close(); } catch (Exception e) { e.printStackTrace(); }
