要保存的图像中的SD卡（闭合）(To save the image in sdcard [close

我写的代码编辑图像，现在我要保存编辑后的图像在SD卡

image=(ImageView)findViewById(R.id.image);
        Intent intent = getIntent();
        File sdCardDirectory = Environment.getExternalStorageDirectory();
        photo = (Bitmap) intent.getParcelableExtra("photoo");
        image.setImageBitmap(photo);

Answer 1:

试试这个，

 void saveImage() {

    String root = Environment.getExternalStorageDirectory().toString();
    File myDir = new File(root + "/saved_images");

    String fname = "Image.jpg";
    File file = new File (myDir, fname);
    if (file.exists ()) file.delete (); 
    try {
           FileOutputStream out = new FileOutputStream(file);
           myBitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
           out.flush();
           out.close();

    } catch (Exception e) {
           e.printStackTrace();
    }
}

Answer 2:

好吧，首先，你需要给在AndroidManifest.xml写权限如下的，

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

现在，让我们来看看，其实写你的编辑图像的代码，

// Getting the SDCard Path
File sdcard = Environment.getExternalStorageDirectory();
File editedFile = new File( sdcard, "myphoto.jpeg" );

// if file is already exists then first delete it
if ( editedFile.exists() ) 
{   
    editedFile.delete(); 
}

FileOutputStream fOut = new FileOutputStream( editedFile );
photo.compress( Bitmap.CompressFormat.JPEG, 90, fOut );

Answer 3:

这是很简单的。

File outpt = new File( sdCardDirectory, "photo.jpeg" );
FileOutputStream outptOs = new FileOutputStream( outpt );
photo.compress( Bitmap.CompressFormat.JPEG, 90, outptOs );
