在android中添加工具栏时出现充气异常

我不熟悉材料设计，我正在尝试一些东西。 对于我的应用程序，最小sdk为21。但是我的应用程序崩溃了，代码如下

工具栏的代码是

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical">

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:background="@color/colorPrimary"
    android:elevation="5dp"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >
</android.support.v7.widget.Toolbar>



</LinearLayout>

我不需要任何向后兼容前Lolipop。 我也找不到任何没有向后支持的教程。 任何帮助对我都会很好

logcat是

无法启动活动组件信息{com.example.sagar.moviesuccesspredictor/com.example.sagar.moviesuccesspredictor.MainActivity}:android.view.InflateException:
二进制XML文件行#9:必须在include标记中指定布局：试试这个

您的toolbar.xml应该是这样的

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/tool_bar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimary"
    app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    >

</android.support.v7.widget.Toolbar>


试试这段代码

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    app:popupTheme="@style/AppTheme.PopupOverlay" />

</android.support.design.widget.AppBarLayout>



并在style.xml中添加这些行

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

您的工具栏id是
工具栏
而不是
工具栏
。使用like

public class MainActivity extends AppCompatActivity  {
Toolbar toolbar;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    toolbar=(Toolbar) findViewById(R.id.toolbar);

  }
}

编辑1：使用工具栏的示例

toolbar.xml

您的
layout=“@layout/toolbar”
在activity\u main.xml中，
toolbar
应该是具有

看一看。这可能会对您有所帮助。
将您的主要活动xml更改为

 <?xml version="1.0" encoding="utf-8"?>
<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"
    tools:context="com.example.sagar.moviesuccesspredictor.MainActivity">
<include
    android:id="@+id/tool_bar"
    layout="@layout/tool_bar"
    tools:layout_editor_absoluteY="45dp"
    tools:layout_editor_absoluteX="0dp" />
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Hello World!"
      android:layout_below="@+id/tool_bar"
        android:layout_marginTop="10dp"/>

</RelativeLayout>



问题出在tag而不是android:layout，你必须使用layout:yourLayoutfile。并确保您在mainActivity中也使用了支持工具栏
Open
logcat
，这可能表明工具栏与现有的ActionBar冲突。解决方案是modifyandroidmanifest.xml

<activity
            android:name=".ToolbarActivity"
            android:label="@string/app_name"
            android:theme="@style/Theme.Design.Light.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>



添加没有默认操作栏的主题。
显示错误日志。stacktrace在哪里？它不显示任何错误05/05 18:03:41：启动应用程序$adb shell am start-n“com.example.sagar.moviesuccesspredictor/com.example.sagar.moviesuccesspredictor.MainActivity”-a android.intent.action.MAIN-c android.intent.category.LAUNCHER-D连接到com.example.sagar.moviesuccesspredictor连接到目标VM，地址：'localhost:8601'，传输：'socket'与目标VM断开连接，地址：'localhost:8601'，传输：“socket”您使用的是兼容样式吗？仍然崩溃。请仔细检查id，并查看其他存储库是否注意到了这一点。但我的应用程序在修复后仍然崩溃，请尝试我编辑的答案。据我所知，这一阶段不需要“setSupportActionBar”这篇文章你的日志可能不太好，原因是：android.view.InflateException:二进制XML文件行#9:你必须在include标记中指定布局：false-true将其添加到样式中，把这个主题应用到你的活动中，比如上面的答案。
