标签： java android android-fragments

我正在制作添加了活动片段的应用程序。现在，我在片段部分添加了搜索栏，因此我想在单击图像时打开导航抽屉（处于活动状态）和操作菜单。

片段看起来像这样-image here

现在如何从fragment.java代码中打开操作菜单和抽屉菜单。请帮忙

答案 0 :(得分：1)

在活动中创建一个公共方法，这将打开导航抽屉并从片段中调用该方法。

活动代码：

Copy

在您的片段图片中，点击代码：

public void openDrawer(){
    drawer.openDrawer(Gravity.LEFT);
}

希望这对您有用！
