Question

我是Android开发的新手。我正在尝试将android-gallery图像发送到服务器。我从相机拍摄照片并在画廊视图中显示拍摄的图像。现在我需要将这些图像发送到服务器数据库。我不知道这样做。听到我的代码到现在为止。

   <Gallery
    android:id="@+id/gallery"
    android:layout_width="match_parent"
    android:layout_height="60dp"
    android:layout_alignParentBottom="true"
    android:layout_alignParentLeft="true"
    android:background="#55000000"
    android:gravity="center_vertical"
    android:spacing="16dp" />

MainActivity

public class MainActivity extends Activity implements
    AdapterView.OnItemSelectedListener, ViewSwitcher.ViewFactory {

Button b;
public static int count = 0;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);

    setContentView(R.layout.activity_main);

    b = (Button) findViewById(R.id.btnSelectPhoto);
    b.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            selectImage();
        }
    });

    Gallery g = (Gallery) findViewById(R.id.gallery);
    g.setAdapter(new ImageAdapter(this, ReadSDCard()));
    g.setOnItemSelectedListener(this);
}

private void selectImage() {
    // TODO Auto-generated method stub

    final CharSequence[] options = { "Take Photo", "Choose from Gallery",
            "Cancel" };

    AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);

    builder.setTitle("Add Photo!");

    builder.setItems(options, new DialogInterface.OnClickListener() {

        @Override
        public void onClick(DialogInterface dialog, int item) {

            if (options[item].equals("Take Photo"))

            {

                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

                final String dir = (android.os.Environment
                        .getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES) + "/picFolderrr/");
                File f = new File(dir);
                f.mkdir();
                count++;

                Uri uriSavedImage = Uri.fromFile(new File(dir + count
                        + ".jpg"));
                intent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
                startActivityForResult(intent, 1);

            }

            else if (options[item].equals("Choose from Gallery"))

            {

                Intent intent = new Intent(
                        Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

                startActivityForResult(intent, 2);

            }

            else if (options[item].equals("Cancel")) {

                dialog.dismiss();

            }

        }

    });

    builder.show();
