java - 如何从我的应用程序中打开已安装的应用程序以共享内容

Question

我需要将手机中安装的所有应用程序都打开到我的android应用程序中以共享内容，我能找到一个简单的方法吗？

Answer 1

如果数据是文本格式，我想你可以试试这个

    Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);

    sharingIntent.setType("text/plain");
    String shareBody = "Here is the share content body";

    sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Subject Here");
    sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);


    startActivity(Intent.createChooser(sharingIntent, "Share via"));

Answer 2

你的问题不清楚。但我想我明白了你的问题。

你想分享一些数据吗？

你必须使用share Intent

这是示例-

共享文本数据-

Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND); 
sharingIntent.setType("text/plain");
String shareBody = "Here is the share content body";
sharingIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Subject Here");
sharingIntent.putExtra(android.content.Intent.EXTRA_TEXT, shareBody);
startActivity(Intent.createChooser(sharingIntent, "Share via"));

分享图像

String fileName = "image-3116.jpg";//Name of an image
String externalStorageDirectory =     Environment.getExternalStorageDirectory().toString();
String myDir = externalStorageDirectory + "/saved_images/"; // the file will be in saved_images
Uri uri = Uri.parse("file:///" + myDir + fileName);
Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("text/html");
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(shareIntent, "Share Deal"));
