But when I switch to layout design

I cannot see the menu anymore.

I already check for menu setting

1. make a onCreateOptionsMenu

2. set menu/main.xml

3. xmlns:tools / tools:context

But it still have no menu bar in there. The code is below:

MainActivity.java

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();
    if(id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

Layout/activity_main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context="com.example.jason.web_control.MainActivity">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_above="@+id/playPauseButton"
            android:clickable="true"
            android:background="@android:color/holo_blue_dark"
            android:id="@+id/mousePad"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true" />

    </RelativeLayout>
</LinearLayout>

menu/menu_main.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.example.jason.web_control.MainActivity">
<item
    android:id="@+id/action_settings"
    android:title="@string/action_settings"
    app:showAsAction="always" />
</menu>

Answer 1

    What I did was                                                                                        

    public MoviesFragment() {
        setHasOptionsMenu(true);
    }
and need to override                                                                                          
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

        int id = item.getItemId();
        switch (id) {

        }
       return super.onOptionsItemSelected(item);
    }
