Now how can I open both action menu and drawer menu from fragment.java code. Please Help in this out
推荐答案
在您的活动中创建一个公共方法，这将打开导航抽屉并从您的片段中调用该方法.
Create a public method in your activity which will open the navigation drawer and call that method from your fragment.
活动代码:
public void openDrawer(){
drawer.openDrawer(Gravity.LEFT);
}
在您的片段图片中，点击代码:
In your fragment image on click code:
imageView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
((MainActivity)getActivity()).openDrawer();
}
}
希望这对您有用！
