我什么图像（位图）从我的Android代码上传到网站上，并得到一个URL回来。有没有我可以使用的简单API，或者我该怎么做？上传与Android网站上的图像（位图），并得到一个URL回到
这是主要的活动，拍了一张照片，并把它在一个位图：
private static final int SELECT_PHOTO = 100;
private static final int TAKE_PHOTO = 101;
static Bitmap yourSelectedImage;
ImageView im;
Uri imageUri;
/***
* Sets up the layout an puts onClickListener() on the buttons
*
*/
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button) findViewById(R.id.button1);
button.setOnClickListener(this);
button = (Button) findViewById(R.id.button2);
button.setOnClickListener(this);
}
/***
* Change intent on the buttons you click
*/
@Override
public void onClick(View v) {
switch(v.getId()){
case R.id.button1:
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, SELECT_PHOTO);
break;
case R.id.button2:
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(intent, TAKE_PHOTO);
break;
}
}
/***
* Puts the image you choosed on the bitmap that you going to paint.
*/
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch(requestCode) {
case SELECT_PHOTO:
if(resultCode == RESULT_OK){
Uri selectedImage = imageReturnedIntent.getData();
InputStream imageStream = null;
try {
imageStream = getContentResolver().openInputStream(selectedImage);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
yourSelectedImage = BitmapFactory.decodeStream(imageStream);
Intent in = new Intent(this,EditPicsActivity.class);
startActivity(in);
}
break;
case TAKE_PHOTO:
if (resultCode == Activity.RESULT_OK) {
Bundle extras = imageReturnedIntent.getExtras();
yourSelectedImage = (Bitmap) extras.get("data");
Intent in = new Intent(this,EditPicsActivity.class);
startActivity(in);
break;
}
}
}
}
继承人，在对位图做修改代码：
public class EditPicsActivity extends Activity implements OnTouchListener {
EditView edit;
float x,y;
Paint paint = new Paint();
float radius = 10;
ArrayList<painting> whatYouEdit = new ArrayList<painting>();
Canvas canvas1;
/***

*/
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
x=y=0;
paint.setColor(Color.BLACK);
edit = new EditView(this);
edit.setOnTouchListener(this);
setContentView(edit);
edit.Start();
}
/***

@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_edit_pics, menu);
return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item){
switch(item.getItemId()){

MediaStore.Images.Media.insertImage(getContentResolver(), MainActivity.yourSelectedImage,
"new pics", "mohahhaa");
break;
case R.id.Clear :
whatYouEdit.clear();
break;
case R.id.Send :
//new SendPicture().execute(MainActivity.yourSelectedImage);
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("text/html");

上的情况下}
在onOptionsItemSelected（菜单项项）方法R.id.Send我喜欢吨o把链接到一个网页，只有图片。
