Question

我正在使用以下代码集成share。

private void socialShare()
    {
        Uri uri = Uri.parse("android.resource://com.example.myproject/drawable/appicon");
        Intent shareIntent = new Intent();
        shareIntent.setAction(Intent.ACTION_SEND);
        shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
        shareIntent.putExtra(Intent.EXTRA_TEXT, "sharing myapp");
        shareIntent.setType("image/jpeg");
        startActivity(Intent.createChooser(shareIntent, "Share from"));
    }

与上面的代码一样，我试图将png image放在drawable文件夹中。但图像无法发送。这是因为在setType中，它是 image / jpeg ？我不能使用jpeg，因为它失去了透明度。有人可以建议我如何与图像分享？

以下是我用于将图像从drawable复制到sdcard的代码：

String commonPath = Environment.getExternalStorageDirectory().toString() + "/MyAppFolder"; 
        File direct = new File(commonPath);

        if(!direct.exists())
        {
            if(direct.mkdir()) 
              {
                Log.d("tag","directory created");
               //directory is created;
              }

        }

        Bitmap bm = BitmapFactory.decodeResource( getResources(), R.drawable.sharingimage);
        OutputStream outStream = null;
           File savingFile = new File(commonPath, "shareImage.png");
           if(!savingFile.exists())
           {
               Log.d("tag","file is created");

           try {
                savingFile.createNewFile();
                outStream = new FileOutputStream(savingFile);
                bm.compress(Bitmap.CompressFormat.PNG, 100, outStream);
                outStream.flush();
                outStream.close();

                Log.d("tag","Saved");

               } catch (FileNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();

               } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();

               }

            }

我找到了解决方案，我不应该在SD卡上复制图像。这是：

    try {
        Uri imageUri = null;
        try {
            imageUri = Uri.parse(MediaStore.Images.Media.insertImage(this.getContentResolver(),
                    BitmapFactory.decodeResource(getResources(), R.drawable.fragment_menu_logo), null, null));
        } catch (NullPointerException e) {
        }
        String text = getString(R.string.share_text);
        // Launch the Google+ share dialog with attribution to your app.
        Intent shareIntent = new PlusShare.Builder(mActivity)
                .setType("image/*")
                .setText(text)
                .addStream(imageUri)
                .getIntent();
        startActivity(shareIntent);
    } catch (android.content.ActivityNotFoundException ex) {
        Toast.makeText(mActivity, mActivity.getString(R.string.share_google_plus_not_installed), Toast.LENGTH_LONG).show();
    }

Bitmap bitmap= BitmapFactory.decodeResource(getResources(),R.drawable.xxxx);
String path = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)+"/LatestShare.jpg";
OutputStream out = null;
File file=new File(path);
try {
    out = new FileOutputStream(file);
    bitmap.compress(Bitmap.CompressFormat.JPEG, 100, out);
    out.flush();
    out.close();
} catch (Exception e) {
    e.printStackTrace();
}
path=file.getPath();
Uri bmpUri = Uri.parse("file://"+path);
Intent shareIntent = new Intent();
shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
shareIntent.putExtra(Intent.EXTRA_STREAM, bmpUri);
shareIntent.setType("image/jpg");
startActivity(Intent.createChooser(shareIntent,"Share with"));

这对我很有用，这需要写入权限

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

将此行添加到Android清单以获取写入权限。

您可以使用以下方法分享...

Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.setType("image/png");
Uri uri = Uri.parse("android.resource://your package name/"+R.drawable.ic_launcher);
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
shareIntent.putExtra(Intent.EXTRA_TEXT, "Hello, This is test Sharing");
startActivity(Intent.createChooser(shareIntent, "Send your image"));

尝试并测试......为我工作

Answer 4

首先添加权限

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

使用res中的位图

Bitmap b =BitmapFactory.decodeResource(getResources(),R.drawable.userimage);
            Intent share = new Intent(Intent.ACTION_SEND);
            share.setType("image/jpeg");
            ByteArrayOutputStream bytes = new ByteArrayOutputStream();
            b.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
            String path = MediaStore.Images.Media.insertImage(getContentResolver(),
                    b, "Title", null);
            Uri imageUri =  Uri.parse(path);
            share.putExtra(Intent.EXTRA_STREAM, imageUri);
            startActivity(Intent.createChooser(share, "Select"));

通过蓝牙测试。

像魅力一样工作。

Answer 5

您无法直接与应用内部存储共享uri（当然，应用的资源将始终位于内部存储中）

实现这一目标的方法有两种。

将图像复制到外部存储，然后从那里共享。请参阅this
编写内容提供商以共享图像。对于那个，请参考Create and Share a File from Internal Storage

在drawable文件夹中共享png图像
