Full Screen Theme for AppCompat

问题:

I would like to know how can I apply full screen theme ( no title bar + no actionbar ) to an activity. I am using AppCompat library from support package v7.

I\'ve tried to applied android:theme=\"@android:style/Theme.NoTitleBar.Fullscreen\" to my specific activity but it crashed. I think it\'s because my application theme is like this.

<style name=\"AppTheme\" parent=\"Theme.AppCompat.Light.DarkActionBar\">

I also have tried this

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

which only hides title bar but not the action bar. My current workaround is that hiding the actionbar with

getSupportActionBar().hide();

回答1:

When you use Theme.AppCompat in your application you can use FullScreenTheme by adding the code below to styles.

<style name=\"Theme.AppCompat.Light.NoActionBar.FullScreen\" parent=\"@style/Theme.AppCompat.Light.NoActionBar\">
    <item name=\"android:windowNoTitle\">true</item>
    <item name=\"android:windowActionBar\">false</item>
    <item name=\"android:windowFullscreen\">true</item>
    <item name=\"android:windowContentOverlay\">@null</item>
</style>

and also mention in your manifest file.

<activity
   android:name=\".activities.FullViewActivity\"
   android:theme=\"@style/Theme.AppCompat.Light.NoActionBar.FullScreen\" 
/>

Based on the answer by @nebyan, I found that the action bar is still not hiding.

The following code works for me:

<style name=\"AppFullScreenTheme\" parent=\"Theme.AppCompat.Light.NoActionBar\">
    <item name=\"android:windowNoTitle\">true</item>
    <item name=\"android:windowActionBar\">false</item>
    <item name=\"android:windowFullscreen\">true</item>
    <item name=\"android:windowContentOverlay\">@null</item>
</style>

and of course dont forgot to edit your AndroidManifest file.

<activity
    android:name=\"YOUR_ACTIVITY_NAME\"
    android:theme=\"@style/AppFullScreenTheme\" 
/>

回答3:

<style name=\"Theme.AppCompat.Light.NoActionBar\" parent=\"@style/Theme.AppCompat\">
    <item name=\"android:windowNoTitle\">true</item>
    <item name=\"android:windowFullscreen\">true</item>
</style>

Using the above xml in style.xml, you will be able to hide the title as well as action bar.

Issues arise among before and after versions of Android 4.0 (API level 14)..

from here https://developer.android.com/training/system-ui/status.html I created my own solution..

@SuppressLint(\"NewApi\")
@Override
protected void onResume()
{
    super.onResume();

    if (Build.VERSION.SDK_INT < 16)
    {
        // Hide the status bar
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        // Hide the action bar
        getSupportActionBar().hide();
    }
    else
    {
        // Hide the status bar
        getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);
        / Hide the action bar
        getActionBar().hide();
    }
}

I write this code in onResume() method because if you exit from your app and then you reopen it, the action bar remains active! (and so this fix the problem)

I hope it was helpful ;)

Your \"workaround\" (hiding the actionBar yourself) is the normal way. But google recommands to always hide the ActionBar when the TitleBar is hidden. Have a look here: https://developer.android.com/training/system-ui/status.html

回答6:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    //to remove \"information bar\" above the action bar
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
    //to remove the action bar (title bar)
    getSupportActionBar().hide();
}

You can follow below step:-

AndoridMenifest.xml

<activity
            android:name=\".ui.FullImageActivity\"
            android:label=\"@string/title_activity_main\"
            android:screenOrientation=\"landscape\"
            android:theme=\"@style/DialogTheme\">
        </activity>

Style.xml

<style name=\"DialogTheme\" parent=\"android:Theme.Dialog\">

    <item name=\"android:layout_width\">fill_parent</item>
    <item name=\"android:layout_height\">fill_parent</item>

   <!-- No backgrounds, titles or window float -->
    <item name=\"android:windowNoTitle\">false</item>
    <item name=\"android:windowFullscreen\">true</item>
    <item name=\"android:windowIsFloating\">false</item>
</style>

FullImageActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
    setContentView(R.layout.image_view);
     }

I hope it will help..Thanks!!

parent=\"@style/Theme.AppCompat.Light.NoActionBar\">
    <item name=\"android:windowNoTitle\">true</item>
    <item name=\"android:windowActionBar\">false</item>

This theme only works after API 21(included). And make both the StatusBar and NavigationBar transparent.

<style name=\"TransparentAppTheme\" parent=\"Theme.AppCompat.Light.DarkActionBar\">
  <item name=\"windowActionBar\">false</item>
  <item name=\"windowNoTitle\">true</item>
  <item name=\"android:statusBarColor\">@android:color/transparent</item>
  <item name=\"android:windowBackground\">@android:color/transparent</item>
  <item name=\"android:navigationBarColor\">@android:color/transparent</item>
  <item name=\"android:windowIsTranslucent\">true</item>
  <item name=\"android:windowContentOverlay\">@null</item>
</style>

回答14:

Simply at this guys to your Style:

<style name=\"AppTheme\" parent=\"@style/Theme.AppCompat.Light\">
<item name=\"windowNoTitle\">true</item>
<item name=\"windowActionBar\">false</item>
<item name=\"android:windowFullscreen\">true</item>
<item name=\"android:windowContentOverlay\">@null</item> </style>

回答15:

To hide both status bar and action bar and make your activity full-screen use the following code in your activity\'s onResume() or onWindowFocusChanged() method:

@Override
protected void onResume() {
    super.onResume();
    View decorView = getWindow().getDecorView();
    decorView.setSystemUiVisibility(
            View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY
            | View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
            | View.SYSTEM_UI_FLAG_FULLSCREEN);
}

Note: Using the xml solutions provide in this thread I could only hide the status bar but not the navigation bar.
