android - ビットマップをアルバムに保存する

Question

次のコードを使用すると、ビットマップが保存され、ギャラリーの「カメラ」アルバムの最後に挿入されます。

MediaStore.Images.Media.insertImage(getContentResolver(), bmp, null , null);

ビットマップをアプリのアルバムに保存するにはどうすればよいですか？

Answer 1

private boolean createFolder(String folderName) {
    // TODO Auto-generated method stub
    boolean success = true;
    if(checkforMedia())
    {
        String newFolder = "/OnTheG/"+folderName;
        String extStorageDirectory = Environment.getExternalStorageDirectory().toString();
        File myNewFolder = new File(extStorageDirectory + newFolder);
        success= myNewFolder.mkdirs();
    }

    else
    {
        success=false;
    }
    return success;


}

use this function to create your folder in sdcard.

Open the camera using this function to store your clicked image at your folder


public void takePhoto1() {
        if (!android.os.Environment.getExternalStorageState().equals(
                android.os.Environment.MEDIA_MOUNTED)) {
            Toast.makeText(Add_View_Images_Activity.this,
                    "Please insert SDcard for capturing photo.",
                    Toast.LENGTH_SHORT).show();
        } else {

            try {

                photo1=new File(path+"/"+System.currentTimeMillis()+".jpg");
                Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);              
                cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(photo1));
                cameraIntent.putExtra("return-data", true);

                startActivityForResult(cameraIntent, 4);
            } catch (Exception e) {
                Toast.makeText(Add_View_Images_Activity.this, ""+e, Toast.LENGTH_LONG).show();
            }
        }

    }


and If you pick a image from the gallery obtain it's path and then move it to your folder using this function


    private void moveTheImage(String path) {
            // TODO Auto-generated method stub
            //  File sd = Environment.getExternalStorageDirectory();
            //     File data = Environment.getDataDirectory();

            String sourceImagePath= path;
            System.out.println("Source path>>>>>>>>>"+path);

            String destinationImagePath= fWrapper.path+getTheName(path);

            File source= new File(sourceImagePath);
            File destination= new File(destinationImagePath);
            Log.d("before copying", "");
            if (source.exists()) {
                try
                {
                    FileChannel src = new FileInputStream(source).getChannel();
                    FileChannel dst = new FileOutputStream(destination).getChannel();
                    dst.transferFrom(src, 0, src.size());
                    src.close();
                    dst.close();
                }

                catch (Exception e) {
                    // TODO: handle exception
                }
            }
        }
