Android共享文件，通过电子邮件或其他应用程序发送

Posted 2021-05-06

我的android应用程序中有一个文件列表，我希望能够获取所选项目并通过电子邮件或任何其他共享应用程序发送。这是我的代码。

Intent sendIntent = new Intent();
                    sendIntent.setAction(Intent.ACTION_SEND);
                    sendIntent.putExtra(Intent.EXTRA_EMAIL, getListView().getCheckedItemIds());
                    sendIntent.setType("text/plain");
                    startActivity(sendIntent);

答案

这是在android中共享文件的代码

Intent intentShareFile = new Intent(Intent.ACTION_SEND);
File fileWithinMyDir = new File(myFilePath);

if(fileWithinMyDir.exists()) {
    intentShareFile.setType("application/pdf");
    intentShareFile.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+myFilePath));

    intentShareFile.putExtra(Intent.EXTRA_SUBJECT,
                        "Sharing File...");
    intentShareFile.putExtra(Intent.EXTRA_TEXT, "Sharing File...");

    startActivity(Intent.createChooser(intentShareFile, "Share File"));
}

另一答案

sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(exportPath));

你也可以制作所有文件的zip file并附加zip文件，以便在android中发送多个文件

另一答案

这适用于每个文件！

private void shareFile(File file) {

    Intent intentShareFile = new Intent(Intent.ACTION_SEND);

    intentShareFile.setType(URLConnection.guessContentTypeFromName(file.getName()));
    intentShareFile.putExtra(Intent.EXTRA_STREAM,
        Uri.parse("file://"+file.getAbsolutePath()));

    //if you need
    //intentShareFile.putExtra(Intent.EXTRA_SUBJECT,"Sharing File Subject);
    //intentShareFile.putExtra(Intent.EXTRA_TEXT, "Sharing File Description");

    startActivity(Intent.createChooser(intentShareFile, "Share File"));

}

Thanx Tusshar-换！

另一答案

使用ACTION_SEND_MULTIPLE向某人提供多个数据

intent.setAction(Intent.ACTION_SEND_MULTIPLE);
intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, arrayUri);
intent.setType("text/plain");
startActivity(intent);

arrayUri是要发送的Uri文件的数组列表。

另一答案

File directory = new File(Environment.getExternalStorageDirectory() + File.separator + BuildConfig.APPLICATION_ID + File.separator + DIRECTORY_VIDEO);
            String fileName = mediaModel.getContentPath().substring(mediaModel.getContentPath().lastIndexOf('/') + 1, mediaModel.getContentPath().length());
            File fileWithinMyDir = new File(directory, fileName);
            if (fileWithinMyDir.exists()) {
                Uri fileUri = FileProvider.getUriForFile(this, getApplicationContext().getPackageName() + ".provider", fileWithinMyDir);
                Intent intent = ShareCompat.IntentBuilder.from(this)
                        .setStream(fileUri) // uri from FileProvider
                        .setType("text/html")
                        .getIntent()
                        .setAction(Intent.ACTION_SEND) //Change if needed
                        .setDataAndType(fileUri, "video/*")
                        .addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
                startActivity(intent);

另一答案

以下是共享或保存文本文件的示例：

private void shareFile(String filePath) {

    File f = new File(filePath);

    Intent intentShareFile = new Intent(Intent.ACTION_SEND);
    File fileWithinMyDir = new File(filePath);

    if (fileWithinMyDir.exists()) {
        intentShareFile.setType("text/*");
        intentShareFile.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + filePath));
        intentShareFile.putExtra(Intent.EXTRA_SUBJECT, "MyApp File Share: " + f.getName());
        intentShareFile.putExtra(Intent.EXTRA_TEXT, "MyApp File Share: " + f.getName());

        this.startActivity(Intent.createChooser(intentShareFile, f.getName()));
    }
}

Intent sendIntent = new Intent();

sendIntent.setAction(Intent.ACTION_SEND);

sendIntent.putExtra(Intent.EXTRA_TEXT, "This is my text to send.");

sendIntent.setType("text/plain");

startActivity(Intent.createChooser(sendIntent, getResources().getText(R.string.send_to)));
