从URL Android的份额形象 [英] android share image from url

问题描述

我想用这个code共享图像：

I want to share an image using this code :

Intent sharingIntent = new Intent(Intent.ACTION_SEND);
Uri imageUri = Uri.parse("http://stacktoheap.com/images/stackoverflow.png");
sharingIntent.setType("image/png");
sharingIntent.putExtra(Intent.EXTRA_STREAM, imageUri);
startActivity(sharingIntent);

我犯了一个按钮，可拨打以上code。份额的意图打开，但如果我点击分享通过彩信我：不能将此图片添加到您的信息，如果Facebook我只拿到了一个文本区域没有我的照片

I made a button that call the code above. The share intent open but I got if I click on "Share by MMS" : "cannot add this picture to your message", If facebook I got only a text area without my picture.

2天努力，但无果而终：（

2 days with trying but without result :(

请帮忙

推荐答案

我使用这些$ C $从CS的本教程

I use these codes from this tutorial

        final ImageView imgview= (ImageView)findViewById(R.id.feedImage1);

                Uri bmpUri = getLocalBitmapUri(imgview);
                if (bmpUri != null) {
                    // Construct a ShareIntent with link to image
                    Intent shareIntent = new Intent();
                    shareIntent.setAction(Intent.ACTION_SEND);
                    shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);
                    shareIntent.setType("image/*");
                    // Launch sharing dialog for image
                    startActivity(Intent.createChooser(shareIntent, "Share Image"));    
                } else {
                    // ...sharing failed, handle error
                }

然后将它添加到你的活动

then add this to your activity

 public Uri getLocalBitmapUri(ImageView imageView) {
    // Extract Bitmap from ImageView drawable
    Drawable drawable = imageView.getDrawable();
    Bitmap bmp = null;
    if (drawable instanceof BitmapDrawable){
       bmp = ((BitmapDrawable) imageView.getDrawable()).getBitmap();
    } else {
       return null;
    }
    // Store image to default external storage directory
    Uri bmpUri = null;
    try {
        File file =  new File(Environment.getExternalStoragePublicDirectory(  
            Environment.DIRECTORY_DOWNLOADS), "share_image_" + System.currentTimeMillis() + ".png");
        file.getParentFile().mkdirs();
        FileOutputStream out = new FileOutputStream(file);
        bmp.compress(Bitmap.CompressFormat.PNG, 90, out);
        out.close();
        bmpUri = Uri.fromFile(file);
    } catch (IOException e) {
        e.printStackTrace();
    }
    return bmpUri;
}

然后添加您的应用程序清单

then add your application manifest

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
