我有一个带有图像的自定义列表视图。现在我需要将该图像从一个活动获取到另一个活动。我使用了以下代码。它可以工作，但它从 Listview 获取相同的图像大小到另一个活动，但我需要根据另一个活动修复它的大小。

    ImageView imageview = (ImageView)itemView.findViewById(R.id.yourImageview);
       Bitmap bitmap = ((BitmapDrawable)imageview.getDrawable()).getBitmap();
       Intent intent = new Intent(activity.this, Nextactivity.class);
       intent.putExtra("contentTwo", bitmap);

     Bitmap receivedimage =(Bitmap) intent.getParcelableExtra("contentTwo");
    imageview = (ImageView) findViewById(R.id.yourimageview);
    imageview.setImageBitmap(receivedimage);

适配器代码：

public Screen(Activity a,
        ArrayList<Data> DataList) {
    // TODO Auto-generated constructor stub
    activity = a;
    bleepDraftDataList = draftDataList;
    inflater = (LayoutInflater) activity
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    imageLoader = new ImageLoader(activity.getApplicationContext());
}

@Override
public int getCount() {
    // TODO Auto-generated method stub
    return bleepDraftDataList.size();
}

@Override
public Object getItem(int position) {
    // TODO Auto-generated method stub
    return position;
}

@Override
public long getItemId(int position) {
    // TODO Auto-generated method stub
    return position;
}

private class ViewHolder {
    private ImageView imageViewleft;
    private ImageView imageViewlright;

}

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    Data = DataList.get(position);
    view = convertView;
    final ViewHolder holder;
    if (convertView == null) {

        view = inflater.inflate(R.layout.something, null);

        holder = new ViewHolder();
        holder.imageViewleft = (ImageView) view
                .findViewById(R.id.imageViewBleeplinecellleft);
        holder.imageViewlright = (ImageView) view
                .findViewById(R.id.imageViewBleeplinecellright);



        view.setTag(holder);

    } else {

        holder = (ViewHolder) view.getTag();
    }
    if (!Data.creator.image.equals("")) {
        holder.imageViewleft.setTag(""
                + Data.creator.image);
        imageLoader.DisplayImage("" + Data.creator.image,
                activity, holder.imageViewleft);
    }
    if (!Data.preview.equals("")) {
        holder.imageViewright.setTag(""
                + Data.preview);
        imageLoader.DisplayImage("" + Data.preview, activity,
    return view
}

}

使用它并设置您希望图像的大小

receivedimage = Bitmap.createScaledBitmap(receivedimage , 260, 260, false); 

  // 260*260 Width* height change this to your requirement

您可以做的另一件事是，在PutExtras 中获取图像路径

Bitmap receivedimage = BitmapFactory.decodeFile(imagepath);

     imageview.setImageBitmap(receivedimage);
