我的活动流程为A - > B - > C。在活动C中有共享选项。分享后想要在活动C中保留位置但是它将转到活动A。
分享意图代码
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
sharingIntent.setType("image/jpeg");
sharingIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + myImageFile.getAbsolutePath()));
sharingIntent.putExtra(Intent.EXTRA_SUBJECT, ""); //"Subject here"
sharingIntent.putExtra(Intent.EXTRA_TEXT, shareBody);
sharingIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
theCtx.startActivity(Intent.createChooser(sharingIntent, "Share via"));
这是我的活动C代码：

点击片段分享按钮后，它将调用共享意图。

您可以通过启动结果活动
来等待Share Activity
Intent sharingIntent = new Intent(Intent.ACTION_SEND);
sharingIntent.setType("image/jpeg");
sharingIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + myImageFile.getAbsolutePath()));
sharingIntent.putExtra(Intent.EXTRA_SUBJECT, ""); //"Subject here"
sharingIntent.putExtra(Intent.EXTRA_TEXT, shareBody);
sharingIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
theCtx.startActivity(Intent.createChooser(sharingIntent, "Share via"), REQUEST_ID); // declare global REQUEST_ID = 999 or whatever
然后您将在onActivityResult接听电话，在分享后做任何您想做的事情。
希望这会有所帮助。
