如何在Android Studio中通过Intent分享GIF

Question

我有一个GIF制作应用程序，现在我想直接从应用程序分享到其他应用程序（GMAIL，WHATSAPP等）

如何从应用程序发送创建的GIF

代码我用于在图库/手机中保存GIF

private void saveGif() {
    new AsyncTask<Void, Integer, Void>() {
        ProgressDialog progressDialog;
        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            progressDialog = new ProgressDialog(GifMakerActivity.this);
            progressDialog.setMax(100);
            progressDialog.setMessage("Please wait..");
            progressDialog.setCancelable(false);
            progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
            progressDialog.show();
        }

        @Override
        protected Void doInBackground(Void... voids) {
            File filePath;
            if (TextUtils.isEmpty(gifPath)) {
                int random = (int) (Math.random() * 9000) + 1000;
                File gifMaker = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), "Gif Maker");
                if (!gifMaker.mkdir()) {
                    Log.e("GifMakerActivity: ", "Directory doesn't exist");
                }
                filePath = new File(gifMaker, "GifMaker_" + random + ".gif");



            } else {
                filePath = new File(gifPath);

            }

                }

            } catch (FileNotFoundException e) {}

如何共享用户创建并与其他应用共享的GIF

有什么方法可以用来解决这个错误。

Answer 1

那么，您可以尝试搜索应用程序的文件并使用intent方法与其他应用程序共享尝试在您的方法中发送文件：

Intent i = new Intent();
i.setAction(Intent.ACTION_SEND);
i.setType("img/*");
i.setPackage("com.whatsapp");
startActivity(i);

Answer 2

使用提供的代码段中的变量filePath创建File Uri以保存数据流，然后使用ACTION_SEND提供此图像数据。 只需调用此方法：

private void shareImage() {
    Intent share = new Intent(Intent.ACTION_SEND);

   // For sharing png image only:
   // setType("image/png"); 
   // For sharing jpeg image only: 
   // setType("image/jpeg");

    share.setType("image/*");

    Uri uri = Uri.fromFile(filePath);
    share.putExtra(Intent.EXTRA_STREAM, uri);
    startActivity( Intent.createChooser(share, "Share this image to your friends!") );
   }

要将某些引用或其他内容作为文本共享，请使用以下方法：

private void shareTextUrl() {
    Intent share = new Intent(Intent.ACTION_SEND);
    share.setType("text/plain");
    share.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
    share.putExtra(Intent.EXTRA_SUBJECT, "Avoiding complexity reduces bugs");
    share.putExtra(Intent.EXTRA_TEXT, "Quote by Linus Torvalds");
    startActivity(Intent.createChooser(share, "Share this quote!"));
}
