我最近开始学习dev android代码。我有这个简单的程序工作正常,直到我尝试集成v7-appcompat允许使用操作栏。现在我的程序在发布时立即崩溃。有什么想法吗?

mrres1:我自己写了但是按照这里的教程:https://developer.android.com/training/basics/actionbar/setting-up.html
我的布局文件:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
android:orientation="horizontal" >
<EditText android:id="@+id/edit_message"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:hint="@string/edit_message" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/button_send"
android:onClick="sendMessage" />
</LinearLayout>
清单文件:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mikemiles"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.mikemiles.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.mikemiles.DisplayMessageActivity"
android:label="@string/title_activity_display_message"
android:parentActivityName="com.mikemiles.myfirstapp.MainActivity" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="com.mikemiles.myfirstapp.MainActivity" />
</activity>
</application>
</manifest>
答案 0 :(得分:0)
在清单
中的MainActivity中添加android:theme="@style/Theme.AppCompat"
<activity android:name="com.mikemiles.MainActivity" android:theme="@style/Theme.AppCompat" android:label="@string/app_name" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity>
