我正在尝试将图像添加到我的Twitter分享意图中.我在一个类中本地保存图像,然后在另一个类中保存图像并尝试附加到我的意图.

这是我的代码

private void shareTwitter(){

    try {

        FileInputStream fis;
        fis = getActivity().openFileInput("photo.jpg");
        Bitmap shot = BitmapFactory.decodeStream(fis);
        File file = new File(MapView.path, "snapshot.jpg");
        if(file.exists()){
            Log.i("FILE", "YES");
        }else{
            Log.i("FILE", "NO");
        }
        Uri uri = Uri.parse(file.getAbsolutePath());
        //Uri uri = Uri.parse("android.resource://com.gobaby.app/drawable/back");             
            Intent intent = new Intent(Intent.ACTION_SEND);
            intent.setType("/*");
            intent.setClassName("com.twitter.android", "com.twitter.android.PostActivity");
            intent.putExtra(Intent.EXTRA_TEXT, "Thiws is a share message");
            intent.putExtra(Intent.EXTRA_STREAM, uri);
            startActivity(intent);            

    } catch (final ActivityNotFoundException e) {
        Toast.makeText(getActivity(), "You don't seem to have twitter installed on this device", Toast.LENGTH_SHORT).show();
    } catch (FileNotFoundException e) {
        // TODO Auto-generated …

我正在使用Picasso库从网址添加标记到我的地图

由于标记不是ImageView,我试图使用Target

for(int x =0; x < mapIcon_url.length; x++){

    Picasso.with(getActivity()).load(mapIcon_url[x]).resize(marker_size, marker_size+15).into(new Target() {

        @Override
        public void onSuccess(Bitmap b) {
            bitmapMarker = BitmapDescriptorFactory.fromBitmap(b);


            //create marker option
            if(b != null)
                markerOptions = new MarkerOptions().position(marker_position).icon(bitmapMarker));
            else
                markerOptions = new MarkerOptions().position(marker_position).icon(BitmapDescriptorFactory.fromResource(R.drawable.placeholder_pin)).snippet(String.valueOf(x));

            marker = map.addMarker(markerOptions);                              
        }

        @Override
        public void onError() {

            //create marker option                                  
            markerOptions = new MarkerOptions().position(marker_position).icon(BitmapDescriptorFactory.fromResource(R.drawable.placeholder_pin)).snippet(String.valueOf(x));
            marker = map.addMarker(markerOptions);

        }
    }); 
}   

我在循环中执行此操作以添加大约20个标记但我发现在第一次运行代码时只添加了5或7个标记,所以我已经切换到使用lib和AsyncTask这样.

for(int x =0; x < mapIcon_url.length; x++){

    new AddMarker().execute(mapIcon_url[x]);
}


public class AddMarker extends AsyncTask<String, Integer, BitmapDescriptor> { …
