从Drawable获取PNG的URI将返回没有任何文件扩展名的空文件

Question

我有一个分享按钮，它将分享一个图片从文字的绘制。

public boolean shareGame(String msg) {
    if (Configuration.Share_WITH_IMAGE) {
        Intent shareIntent = new Intent();
        shareIntent.setAction(Intent.ACTION_SEND);
        shareIntent.setType("image/png");
        Uri uri = Uri
                .parse("android.resource://" + getPackageName() + "/" + R.drawable.share_image);

        shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
        shareIntent.putExtra(Intent.EXTRA_TEXT, msg + " " + GOOGLE_PLAY_URL);
        startActivity(Intent.createChooser(shareIntent, "Share: " + msg));
    } else {
        Intent sendIntent = new Intent();
        sendIntent.setAction(Intent.ACTION_SEND);
        sendIntent.putExtra(Intent.EXTRA_TEXT, msg + GOOGLE_PLAY_URL);
        sendIntent.setType("text/plain");
        startActivity(Intent.createChooser(sendIntent, msg));
    }

    return true;

}

多谢了。

这个代码起作用..我已经在gmail和whatsapp上测试了它

Bitmap icon = BitmapFactory.decodeResource(getResources(),
            R.drawable.ic_launcher);
    Intent share = new Intent(Intent.ACTION_SEND);
    share.setType("image/jpeg");
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    icon.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    File f = new File(Environment.getExternalStorageDirectory()
            + File.separator + "share_image.jpg");

    try {
        f.createNewFile();
        FileOutputStream fo = new FileOutputStream(f);
        fo.write(bytes.toByteArray());

    } catch (IOException e) {
        e.printStackTrace();
    }
    share.putExtra(Intent.EXTRA_TEXT, "send text");

    share.putExtra(Intent.EXTRA_STREAM,
            Uri.parse("file:///sdcard/share_image.jpg"));
    startActivity(Intent.createChooser(share, "Share Image"));
