Question

我想与whatsapp等可用的应用程序共享.gif，但无法在我的可绘制资源中获得有效的Uri gri。

 Uri path = Uri.parse("android.resource://my_package_name/" + R.drawable.gif_1);
    Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
    shareIntent.setType("image/gif");
    shareIntent.putExtra(Intent.EXTRA_STREAM, path);

共享图像有很多解决方案，但gif共享没有解决方案，请帮忙

我找到了答案，我刚创建了一个扩展名为.gif的文件，它对我有用。请参阅以下代码：

private void shareGif(String resourceName){

    String baseDir = Environment.getExternalStorageDirectory().getAbsolutePath();
    String fileName = "sharingGif.gif";

    File sharingGifFile = new File(baseDir, fileName);

    try {
        byte[] readData = new byte[1024*500];
        InputStream fis = getResources().openRawResource(getResources().getIdentifier(resourceName, "drawable", getPackageName()));

        FileOutputStream fos = new FileOutputStream(sharingGifFile);
        int i = fis.read(readData);

        while (i != -1) {
            fos.write(readData, 0, i);
            i = fis.read(readData);
        }

        fos.close();
    } catch (IOException io) {
    }
    Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
    shareIntent.setType("image/gif");
    Uri uri = Uri.fromFile(sharingGifFile);
    shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
    startActivity(Intent.createChooser(shareIntent, "Share Emoji"));
}

if you want to take image from internal storage.

//this is method having internal storage path.
 private String getFilePath2() {
    String root = Environment.getExternalStorageDirectory().toString();
    File myDir = new File(root + "/Gifs temp/");
    if (!myDir.exists())
        myDir.mkdirs();
    String fname = "temp_gif";
    SimpleDateFormat timeStampFormat = new SimpleDateFormat(
            "yyyyMMdd_HHmmss");
    Date myDate = new Date();
    String filename = timeStampFormat.format(myDate);
    File file = new File(myDir, fname + "_" + filename + ".gif");
    if (file.exists()) {
        file.delete();
    }
    String str = file.getAbsolutePath();
    return str;
}




 //   Then take image from internal storage into the string.
  String st = getFilePath2();




 //And share this by this intent
 Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
                            shareIntent.setType("image/gif");
                            Uri uri = Uri.fromFile(sharingGifFile);
                            shareIntent.putExtra(Intent.EXTRA_STREAM,        
  uri);

  startActivity(Intent.createChooser(shareIntent, "Share Emoji"));
