How to completely remove the "status bar" and modify it?

  • 772

enter image description here

I have a type Fragment, where I have implemented a ListViewwith certain characters. It turns out that I had the typical blue bar above with the name of the App and through manifestit I have removed it but I cannot take advantage of its space, that is, it does not reach the ListViewtop, only until the beginning of the supposed top bar, and It takes up a lot of space.

Is it possible to deactivate it completely to be able to take advantage of the whole screen?

Another thing you can see is the BottomBarbottom one, red, since the typical Android buttons are there, it starts higher, is there any way to lower it or adapt it to the buttons even more?

UPDATED:

activity_main.xml

< LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"

xmlns:app="http://schemas.android.com/apk/res-auto"

android:orientation="vertical"

android:layout_height="match_parent">

<FrameLayout

    android:id="@+id/frame"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

    Try to place before the setContenView:

    requestWindowFeature(Window.FEATURE_NO_TITLE);
getActivity().getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
                                WindowManager.LayoutParams.FLAG_FULLSCREEN);

    This will put you full screen and take up your entire screen, that includes hiding the Android navigation controls . In case it doesn't work, add another Flag withSYSTEM_UI_FLAG_HIDE_NAVIGATION

    Here I show you another way:

    if ( Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT )
        {
            getActivity().getWindow().getDecorView().setSystemUiVisibility( 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 
                    | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY );
        }

  2. How to completely remove the “default” bar above and modify it?

    I assume you mean the status bar :

    enter image description here

    Delete it and you see something similar to:

    enter image description here

    You can do it this way:

    View decorView = getWindow().getDecorView();
// Hide the status bar.
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
// Remember that you should never show the action bar if the
// status bar is hidden, so hide that too if necessary.
ActionBar actionBar = getActionBar();
actionBar.hide();

    For android 4.0 and earlier you can define a theme without "ActionBar" in your Activity:

    <application
    ...
    android:theme="@android:style/Theme.Holo.NoActionBar.Fullscreen" >
    ...
</application>

    If you use support with AppCompat:

       <application
        ...
        android:theme="@style/Theme.AppCompat.NoActionBar">
        ...
    </application>

    Check the documentation about your question.

  3. I think the error comes from XMLif you are in a Fragmentmeans you come from a Activity.. then .. you have a Layoutwhere you do this

    <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
             xmlns:tools="http://schemas.android.com/tools"
             android:layout_width="match_parent"
             android:layout_height="match_parent">

  <LinearLayout
               android:layout_width="match_parent"
               android:layout_height="match_parent"
               android:orientation="vertical">
    <include layout="@layout/toolbar"/> <!-- Toolbar incluído-->

    <FrameLayout
                android:id="@+id/contenedor_fragment"
                android:layout_width="match_parent"
                android:layout_height="0dp"
                android:layout_weight="1"/>
 </LinearLayout>
<fragment../>
</android.support.v4.widget.DrawerLayout>

    So every time you make one replaceof Fragmentthe more code you have to solve it, you could not occupy the space that is left over in the image, why did you define the XML wrong... in any case, the action you should take is to assign each Fragmentone Toolbar, of course all you need to add

    Then you would have to remove the Toolbarand you Activitywould look like this

    <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
                 xmlns:tools="http://schemas.android.com/tools"
                 android:layout_width="match_parent"
                 android:layout_height="match_parent">

      <LinearLayout
                   android:layout_width="match_parent"
                   android:layout_height="match_parent"
                   android:orientation="vertical">
        <!--<include layout="@layout/toolbar"/> -->

        <FrameLayout
                    android:id="@+id/contenedor_fragment"
                    android:layout_width="match_parent"
                    android:layout_height="0dp"
                    android:layout_weight="1"/>
     </LinearLayout>
    <fragment../>
    </android.support.v4.widget.DrawerLayout>

    Now if you want to remove the Toolbardefault you have to go to styles.xml and add these 2 lines of code

    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="windowNoTitle">true</item> <!--eliminar titulo-->
        <item name="windowActionBar">false</item> <!--eliminar toolbar-->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
</style>
