android – 使用ACTION_SEND共享文本文件

我们可以使用ACTION_SEND打开共享对话框来共享文本

Intent sendIntent = new Intent();
                sendIntent.setAction(Intent.ACTION_SEND);
                sendIntent.putExtra(Intent.EXTRA_TEXT,"Download Link: Android play store link");
                sendIntent.setType("text/plain");
                startActivity(Intent.createChooser(sendIntent,"Share This App"));

如何使用ACTION_SEND共享文本文件.

我读了http://developer.android.com/training/sharing/send.html,但无法获得如何共享文本文件.

解决方法

使用以下行.

Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); 
    emailIntent.setType("*/*");
    emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,new String[] {"[e-mail]"}); 
    emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"Test Subject"); 
    emailIntent.putExtra(android.content.Intent.EXTRA_TEXT,"go on read the emails");     
    emailIntent.putExtra(Intent.EXTRA_STREAM,Uri.fromfile(new File(yourtextfilepath));
    startActivity(Intent.createChooser(emailIntent,"Send mail..."));

确保文本文件路径应来自外部存储卡.动作发送不接受内部存储器中的文件.

希望这会帮助你.
