    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="YT Studio"
        android:theme="@style/AppTheme"
        android:resizeableActivity = "true">
        <activity
            android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

main.xml

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:text="@string/hello_world"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="30dp" />

</LinearLayout>

edit: one fellow asked me for code, there you go

package com.mycompany.myapp;

import android.app.*;
import android.os.*;

public class MainActivity extends Activity 
{
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        getSupportActionBar().hide();
    }
}

CodePudding user response：

Go to src/main/res/values & open theme.xml :

then change your style name to NoActionBar , it remove your action bar :

CodePudding user response：

Go to res >> values >> themes

<style name="Theme.MyAppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
...
...
</style>

change it to Theme.MaterialComponents.Light.NoActionBar , the magic here is the NoActionBar and your toolbar will be remove completely including the app title name. But you should know this, after you change it , its gonna be remove from your entire project not just the single activity.

CodePudding user response：

You can just call

getSupportActionBar().hide();

in your activity's onCreate() method.

Edit

The method given above does not work when using AndroidX activity. It works with AppCompatActivity.

So, this answer will do the task.

In your AndroidManifest.xml, find your activity and then you should add this line in it:

<application>
   ...
   <activity
      android:name=".MainActivity"
      android:theme="@android:style/Theme.NoTitleBar">
         ...
   </activity>
   ...
</application>
