嗨，在我的 android phonegap 应用程序中，我使用创建选择器从移动设备获取所有共享应用程序。它工作正常，但我需要为 facebook 调用单独的意图。所以我需要从对话框中为 facebook 的单击事件。

这是我的代码：

Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
    emailIntent.setType("text/plain");
    emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject );  
    emailIntent.putExtra(android.content.Intent.EXTRA_TEXT,"www.google.com");

    this.ctx.startActivity(Intent.createChooser(emailIntent, "Share"));

请指导我。在此先感谢。

尝试这个：

  try {
        Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
        String[] recipients = new String[]{"e-mail address"};
        emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, recipients);
        emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "E-mail subject");
        emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "E-mail text");
        emailIntent.setType("plain/text"); // This is incorrect MIME, but Gmail is one of the only apps that responds to it - this might need to be replaced with text/plain for Facebook
        final PackageManager pm = getPackageManager();
        final List<ResolveInfo> matches = pm.queryIntentActivities(emailIntent, 0);
        ResolveInfo best = null;
        for (final ResolveInfo info : matches)
            if (info.activityInfo.packageName.endsWith(".gm") ||
                    info.activityInfo.name.toLowerCase().contains("gmail")) best = info;
                if (best != null)
                    emailIntent.setClassName(best.activityInfo.packageName, best.activityInfo.name);
                startActivity(emailIntent);
    } catch (Exception e) {
        Toast.makeText(this, "Application not found", Toast.LENGTH_SHORT).show();
    }

您也可以尝试使用uaual方式：

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, "The status update text");
startActivity(Intent.createChooser(intent, "Dialog title text"));
