启动画面应用程序并隐藏操作栏

Question

我试图弄清楚如何隐藏动态栏以进行启动画面活动.我做了一些在我的启动画面上隐藏我的操作栏的东西,但是有一个问题:在我的启动画面出现之前,有一个活动,其中一个动作栏出现了短暂的...我不知道如何隐藏它!

我的启动画面仅在我们第一次触摸应用程序时出现,就像应用程序的介绍一样.

代码:

package com.example.basicmaponline;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Window;

public class Intro extends Activity{

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);


    getWindow().requestFeature(Window.FEATURE_ACTION_BAR);
    getActionBar().hide();

    setContentView(R.layout.intro);

    Thread timer = new Thread(){
        public void run(){
            try{
                sleep(3000);
            }catch (InterruptedException e) {
                e.printStackTrace();
            }finally{
                Intent openMenu = new Intent("com.example.basicmaponline.MENU");
                startActivity(openMenu);
            }
        }
    };
    timer.start();
}

@Override
protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    finish();
}

}

为什么不在清单中添加第一个活动的主题来排除操作栏,甚至可能是通知栏？

就像是:

<application
    android:allowBackup="true"
    android:icon="@drawable/lojacidadao"
    android:label="@string/app_name"
     android:theme="@style/AppTheme">
    <activity
        android:name="com.example.basicmaponline.Intro"
        android:screenOrientation="portrait"
        android:label="@string/app_name" 
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

顺便说一下,你有动作栏的原因是因为你已经在应用程序标签中设置了默认主题,因此它不是你之前的活动,它实际上是你自己的启动活动.

如果您的构建目标 sdk 5.0 或更高版本（AppTheme 样式为 Theme.AppCompat.Light.DarkActionBar。）

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