Bundle podesavanja = getIntent().getExtras();
PozivIzMenija=podesavanja.getBoolean("PozivIzMenija");
嗯，我可以从我的主要活动开始此活动，而不提供捆绑包。如果我尝试从接收者或服务开始此活动，则会发生这种情况。仅当我从某个菜单活动开始此活动时，才会提供捆绑包。在何处以及如何实施您的建议？我将尝试如何看到？很抱歉，我是一个noob。找到了它。这是一个：PozivIzMenija=podesavanja.getBoolean（“PozivIzMenija”）；如果您正在使用Eclipse，您可以打开shootthedukActivity.java文件并按CTRL+L，键入61，它将转到代码中的该行。然后它就是Bundle。在接收器中添加空检查或提供一些额外内容。
