android - splash screen application and hide action bar

Question

I'm trying to figure out how is it possible to hide the action bar for a splash screen activity. I did something which hide my action bar on my splash screen, but there is one problem: before my splash screen appears, there is like an activity with an action bar who appears briefly... and I don't know how to hide it!

My splash screen only appears when we touch the application for the first time like an introduction of the application.

Code :

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();
}

}

Answer 1

why not add to the manifest the theme of the first activity to exclude the action bar, and maybe even the notification bar?

something like:

<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>
 ...

This should work if you extend the normal Activity class.

If your Activity extends AppCompatActivity instead, use this theme for example:

  <style name="AppTheme.Splash" parent="@style/Theme.AppCompat.NoActionBar">
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
  </style>

meaning :

 <activity ...            
    android:theme="@style/AppTheme.Splash" >
    ...

BTW, the reason you have the action bar is because you have set the default theme to have it, in the application tag, so it's not an activity before yours, it's really your own splash activity.
