我在
Android工作室使用材料设计为前棒棒糖设备创建一个Android应用程序,我是android工作室的新手我正在我的项目中创建一个工具栏但我收到一个错误名为“引起：android.view.InflateException：你必须在include标签中指定一个布局：“请帮我解决这个问题,这是我的活动代码：
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://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.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://schemas.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:

解决方法
我找到了自己问题的答案.在我的工具activity_main xml布局中,我用layout =“@ layout / tool_bar”替换了android：layout =“@ layout / tool_bar”,并在工具栏布局中使用android.support.v7.widget.Tool bar替换了android.widget.Toolbar
查看我的两个xml文件
查看我的两个xml文件
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.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>
更正并使用xml：
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<include
android:id="@+id/tool_bar"
layout="@layout/tool_bar" />
</RelativeLayout>
