應用時崩潰工具欄

Question

我是Android編程新手。當我將該工具欄應用於我的應用程序時遇到此問題，並在嘗試運行該應用程序時崩潰。下面是代碼：

ToolbarActivity.java 

package com.example.toolbar; 

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


public class ToolbarActivity extends ActionBarActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_toolbar); 

     Toolbar toolbar = (Toolbar) findViewById(R.id.my_awesome_toolbar); 
     if (toolbar != null) { 
      setSupportActionBar(toolbar); 
      getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
     } 
    } 


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

} 

activity_toolbar.xml 
<?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:orientation="vertical" > 

    <android.support.v7.widget.Toolbar 
     xmlns:app="http://schemas.android.com/apk/res-auto" 
     android:id="@+id/my_awesome_toolbar" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:minHeight="?attr/actionBarSize" 
     android:background="?attr/colorPrimaryDark" 

     app:theme="@style/ThemeOverlay.AppCompat.ActionBar"> 

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


    <TextView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="page 1" 
     /> 

</LinearLayout> 

，這裏是我的logcat的：

誰能告訴我是什麼問題？我已經將appcompat_v7與我的項目一起包括在內。謝謝。

Answer 1

您可以在logcat的輸出看便知：

不要求Window.FEATURE_ACTION_BAR， 集windowActionBar在你的主題中使用一個工具欄，而不是假的。

同時嘗試使用this link這link

確保您使用：如果你使用Toolbar從V7支持，你應該使用Theme.AppCombat

<item name="windowActionBar">false</item> 

在你的主題

Answer 2

您Activity。

定義你的風格在styles.xml

<style name="AppTheme" parent="Theme.AppCompat"> 
    <item name="colorPrimary">@color/black</item> 
</style> 
<color name="black">#000000</color> 

而且它在AndroidManifest.xml

<application 
     android:icon="@drawable/ic_launcher" 
     android:label="@string/app_name" 
     android:theme="@style/AppTheme" > 

Answer 3

適用於整個應用程序（或specyfic Activity）嘗試此修復程序，它爲我工作：
