android-5.0-lollipop – 如何修复’你必须在include标签中指定一个布局：’

package sample.lakshman.com.sampleltester;

import android.support.v7.app.ActionBarActivity;
import android.os.bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.support.v7.widget.Toolbar;


public class MainActivity extends ActionBarActivity {
    public Toolbar toolbar;

    @Override
    protected void onCreate(Bundle savedInstanceStatE) {
        super.onCreate(savedInstanceStatE);
        setContentView(R.layout.activity_main);
        toolbar = (Toolbar) findViewById(R.id.tool_bar);
        setSupportActionBar(toolbar);
    }


    @Override
    public Boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main,menu);
        return true;
    }

    @Override
    public Boolean onOptionsItemSELEcted(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button,so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_setTings) {
            return true;
        }

        return super.onOptionsItemSELEcted(item);
    }
}

这是我的xml：

<RelativeLayout xmlns:android="http://@R_450_10906@mas.android.com/apk/res/android"
    xmlns:tools="http://@R_450_10906@mas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <include
        android:id="@+id/tool_bar"
        android:layout="@layout/tool_bar" />
</RelativeLayout>

这是我的工具栏Xml：

<?xml version="1.0" encoding="utf-8"?>
    <android.widget.Toolbar xmlns:android="http://@R_450_10906@mas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:BACkground="#E91E63">

    </android.widget.Toolbar>


This is my logcat:
