작업 표시 줄을 영구적으로 비활성화하는 방법

작업 표시 줄을 영구적으로 비활성화하는 방법

---

이 코드를 사용하여 벌집에서 작업 표시 줄을 숨길 수 있습니다.

getActionBar().hide();

그러나 키보드가 열리고 사용자가 아무 것도 복사하여 붙여 넣으면 작업 표시 줄이 다시 표시됩니다. 작업 표시 줄을 영구적으로 비활성화하려면 어떻게합니까?

3.2 이전 장치 Theme.Holo.Light에서 Theme.Holo.Light.NoActionBar변형 을 사용하려는 경우 다음에 추가 할 수 있습니다 styles.xml.

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

그런 다음 활동 테마로 설정하십시오.

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

---

매니페스트에서 활동 테마를 설정하면

<activity
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
....
>

---

내 onCreate 함수 내에서 다음 코드를 사용합니다.

ActionBar actionBar = getSupportActionBar();
actionBar.hide();

---

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

아마도 이것은 당신을 도울 것입니다

Android Studio에서 기본적으로 생성 된 Activity 수퍼 클래스는 ActionBarActivity다른 응답의 솔루션이 작동하지 않습니다. 슈퍼 클래스 변경을 해결하려면 다음을 수행하십시오.

public class xxxActivity extends ActionBarActivity{

에:

public class xxxActivity extends Activity {

---

사용자 정의 테마를 제공하고 작업 표시 줄을 제공하지 않는 가장 좋은 방법은 프로젝트의 모든 활동에 대해 SuperClass를 작성하고 onCreate ()에서 다음 코드 행을 호출하는 것입니다.

this.requestWindowFeature(Window.FEATURE_NO_TITLE);

그것은 항상 나를 위해 작동합니다. 이 방법의 유일한 문제는 앱을 시작할 때 몇 분의 작업 표시 줄이 표시된다는 것입니다 (활동이 아니라 완전한 앱).

---

actionBar 및 Title없이 전체 화면을 표시하려는 경우.

style.xml에 추가하십시오.

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

manifest.xml에서 스타일을 사용하십시오.

android:theme="@style/AppTheme.NoActionBar" 

---

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_my);
    getSupportActionBar().hide();
}

---

styles.xml로 이동이 DarkActionBar를 NoActionBar로 변경하십시오.

style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

---

Holo 테마를 사용하지 않으면 작업 표시 줄이 사라집니다. 이 코드는 지원 lib v7과 함께 API 8 이상에서 작동합니다.

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

활동에 대한 테마를 설정하십시오.

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

그리고 당신의 활동 수업에서.

ActionBarActivity를 확장하더라도 작동합니다.

If you just want a theme with no action bar you can use 'NoActionBar' variant, for eg. if your base theme is as below

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

then you can use

<style name="AppThemeNoActionBar" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

But if you want to retain the properties of your main theme i.e. AppTheme you can do as below

<style name="AppThemeNoActionBar" parent="AppTheme">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

You can retain all the properties of your base theme this way and don't have to explicitly add them in your NoActionBar theme :)

---

Heres a quick solution.

You find styles.xml and you change the base application theme to "Theme.AppCompat.NoActionBar" as shown below.

<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
    <!-- Customize your theme here. -->
</style>

---

You can force hide the action bar simply:

ActionBar  actionbar = getSupportActionBar();
actionBar.hide();

Just use your default theme.

---

Under res -> values ->styles.xml

Change

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

To

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

---

Below are the steps for hiding the action bar permanently:

1. Open app/res/values/styles.xml.
2. Look for the style element that is named "apptheme". Should look similar to <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">.

3. Now replace the parent with any other theme that contains "NoActionBar" in its name.

   a. You can also check how a theme looks by switching to the design tab of activity_main.xml and then trying out each theme provided in the theme drop-down list of the UI.

4. If your MainActivity extends AppCompatActivity, make sure you use an AppCompat theme.

---

Type this code to your onCreate method before setContentView:

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 0);

---

I would like to post rather a Designer approach to this, this will keep design separate from your business logic:

Step 1. Create new style in (res->values->styles.xml) : Basically it is copy of your overall scheme with different parent - parent="Theme.AppCompat.Light.NoActionBar"

<!-- custom application theme. -->
    <style name="MarkitTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimary</item>
        <item name="colorAccent">@color/colorAccent</item>

        <item name="android:windowNoTitle">true</item>
    </style>

Step 2: In your AndroidManifest.xml, add this theme to the activity you want in: e.g. I want my main activity without action-bar so add this like below:

<activity android:name=".MainActivity"
            android:theme="@style/MarkitTheme">

This is the best solution for me after trying a lot of things.

---

Make sure you create a new theme by changing the name of the default theme in the styles.xml file to:

 <style name="MyTheme" parent="android:Theme.Material.Light.NoActionBar">

and than change the theme from the drop-down under your main_activity.xml to whatever you called your theme.

---

Another interesting solution where you want to retain the ViewPager while removing the action bar is to have a style as show

<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:windowActionBarOverlay">true</item>
    <item name="android:actionBarStyle">@style/NoActionBarStyle</item>
    <item name="android:windowContentOverlay">@null</item>
</style>
<style name="NoActionBarStyle" parent="android:Widget.Holo.ActionBar">
    <item name="android:backgroundSplit">@null</item>
    <item name="android:displayOptions"></item>
</style>

This is the way most of the Dialer applications in android is showing the ViewPager without the action bar.

in the onCreate function add the following code

ActionBar actionBar = getSupportActionBar();
actionBar.hide();

and just import android.support.v7.app.ActionBar

---

try this in your manifist

 <activity
        android:name=".MainActivity"
        android:theme="@android:style/Theme.Holo.NoActionBar"
        android:label="@string/app_name" >

---

  protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   android.support.v7.app.ActionBar actionBar = getSupportActionBar();
    if (actionBar != null) {
        actionBar.hide();
    }
    setContentView(R.layout.activity_main);

---

There are two ways to disable ActionBar in Android.

requestWindowFeature(Window.FEATURE_NO_TITLE); 
setContentView(R.layout.activity_main); 

---

I use this solution:

in the manifest, inside your activity tag:

android:label="@string/empty_string"

and in strings.xml:

<string name="empty_string">""</string>

This way you keep ActionBar (or Toolbar) with the title, but when Activity if created the title is automatically empty.

---

Strangely enough, none of these worked for me when building on a Nexus 7 running 4.4.2 (API 19). For the most part, at least with the latest version of Android Studio (1.2.1.1) after creating a blank activity app, the:

android:theme="@style/AppTheme"

is in the application element, not the activity element. If I removed the above code or tried to change it to:

android:theme="@android:style/Theme.Holo.Light.NoActionBar"

the app won't run...if this is happening to you, just go into your styles.xml file (res > values > styles.xml) and add the .NoTitleBar to the end of the parent like this block:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"></style>

No changes to the AndroidManifest file are needed.
