android - 快捷方式主屏幕，如何发送额外内容

Question

我在某处读到(但我再也找不到了)，应该可以从设备主屏幕上的快捷方式发送额外内容。我成功地创建了一个快捷方式，但是 Bundle extras = getIntent().getExtras(); 给出了一个空指针。

我创建的快捷方式如下:

   Intent shortcutIntent = new Intent(this.getApplicationContext(),
                        Shortcut_Activity.class);

                shortcutIntent.setAction(Intent.ACTION_MAIN);

                Intent addIntent = new Intent();
                addIntent
                        .putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
                addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, name);
                addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,
                        Intent.ShortcutIconResource.fromContext(this.getApplicationContext(),
                                R.drawable.ic_shortcut));
                addIntent.putExtra("ID", id); //THIS IS THE EXTRA DATA I WANT TO ATTACH
                addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
                this.getApplicationContext().sendBroadcast(addIntent);

这可能吗？如果是，怎么做？

是的，我已经实现了，这是代码

private void addShortcut() {
    //Adding shortcut for MainActivity 
    //on Home screen
    Intent shortcutIntent = new Intent(getApplicationContext(),
            HOMESHORTCUT.class);
    //Set Extra
    shortcutIntent.putExtra("extra", "shortCutTest ");

    shortcutIntent.setAction(Intent.ACTION_MAIN);

    Intent addIntent = new Intent();
    addIntent
            .putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
    addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "HelloWorldShortcut");
    addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,
            Intent.ShortcutIconResource.fromContext(getApplicationContext(),
                    R.drawable.ic_launcher));

    addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");

    getApplicationContext().sendBroadcast(addIntent);


}
//GET Extra in HOMESHORTCUT activity.
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mTextExtra=new TextView(this);
        Bundle bundel=getIntent().getExtras();
        String getExString=getIntent().getExtras().getString("extra");
        mTextExtra.setText(getExString);
        setContentView(mTextExtra);
    }
