Java 需要一个新的解决方案来禁用android中的主菜单按钮吗

我找了很多东西，几乎什么都试过了，但什么都不管用。 我只想禁用主页和菜单按钮

下面是LockScreenActivity.java

    @Override
    public void onDestroy() {

使用以下方法隐藏主/菜单按钮：

getActionBar().setDisplayHomeAsUpEnabled(false)

或使用

 getActionBar().setHomeButtonEnabled (false)

---

禁用与主/向上提供的交互。

您是否尝试过

getSupportActionBar（）。setDisplayHomeAsUpEnabled（false）？我已经在LockScreenUtils中添加了它。java类，但当我将其添加到LockScreenActivity.java中的onCreate方法中时，应用程序崩溃并且无法打开。现在，我尝试了eclipse的快速解决方案，它添加了这个@SuppressLint（“NewApi”）@覆盖，以便我能够编写getActionBar（）。setHomeButtonEnabled（false）home按钮仍然处于启用状态–收到一个错误，说调用需要min sdk“14”，当我将minSdk更改为14时，我的应用程序没有启动，它崩溃了@Kishudroidw你的日志猫说什么？在清单中添加安卓：主题=“@android:style/theme.Holo.Light”。请查看我的日志猫说了什么。我补充说，只有当我将MinSDK从11更改为14时，才会发生这种情况
