Question

我尝试在Android 2.2中使用appcompat for support actionbar，但是当我构建应用程序时，崩溃首先，我将AppCompat添加为库。这是我的Splash.Class;

package com.skyline.faceball;

import android.os.Bundle;
import android.os.Handler;
import android.app.Activity;
import android.content.Intent;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;

public class Splash extends ActionBarActivity{

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

        startActivity(new Intent(Splash.this, Main.class));  
    }

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

}

在表现中我将其改为：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.skyline.faceball"
    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/Theme.AppCompat" >
        <activity
            android:name="com.skyline.faceball.Splash"
            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.skyline.faceball.Main"
            android:label="@string/title_activity_main" >
        </activity>
    </application>

</manifest>

并查看我的日志：

andmy Main.Class

package com.skyline.faceball;

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

public class Main extends ActionBarActivity{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        getSupportActionBar().setTitle("Main");
    }

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

}

如何删除此问题？感谢。

在以下地方试试：

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




 public boolean onCreateOptionsMenu(Menu menu) {  
        // Removing this prevents the crash: 
        getMenuInflater().inflate(R.menu.main, menu); 
        MenuItem searchItem = menu.findItem(R.id.action_search);
        searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
        return true;
    }

添加appcompat后，应用程序在2.2中崩溃
