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

Answer 1

You're problem are these lines

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

They are not needed as there should be no ActionBar to call at all, the splash screen does not use one and should be a completely separate Activity than your others.

You need two Activities. One for the Splash Screen with it's own layout. The 2nd is for the main Activity, which can be a login screen or welcome screen etc.

The splash screen class should look like this

public class SplashScreen extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    this.requestWindowFeature(Window.FEATURE_NO_TITLE);

    setContentView(R.layout.yourlayoutfile);

    Thread loading = new Thread() {
        public void run() {
            try {
                sleep(5000);
                Intent main = new Intent(SplashScreen.this, Main.class);
                startActivity(main);
            }

            catch (Exception e) {
                e.printStackTrace();
            }

            finally {
                finish();
            }
        }
    };

    loading.start();
}

}

XML File

<?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:id="@+id/LinearLayout1"    
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical"    
tools:context=".SplashScreen" >

// if not using an image replace with whatever is to be shown on the splash screen
<ImageView  
    android:id="@+id/imageView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/logo" />

</LinearLayout>

Now the 2nd Activity has the layout with the ActionBar etc.

Small And Sweet, eazy

Do on In OnCreate

View decorView = getWindow().getDecorView();
        int uiOptions = View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                | View.SYSTEM_UI_FLAG_FULLSCREEN;
        decorView.setSystemUiVisibility(uiOptions);

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.

//add to AndroidManifest for SplashScreen
<activity
         android:name="<YOUR_PACKAGENAME.ACTIVITY>"
         android:theme="@style/AppTheme.NoActionBar"
         .........../>
//add this styles to  styles.xml

 <style name="AppTheme.NoActionBar">
    <item name="android:background">@android:color/transparent</item>
    <item name="android:windowDisablePreview">true</item>
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowBackground">@null</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

//add this code to Activity
public class SplashScreen extends AppCompatActivity {
.
.
    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    .
    .
    .
    }

}

if your build target sdk 5.0 or over (AppTheme style is 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>
