Android splash screen does not display image full screen

Question

I have the code as below in my Android app.

My res/values/styles.xml:

   <style name="FullScreen" 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>
   <item       name="android:windowBackground">@drawable/background_splash</item>
   </style>

res/drawable/background_splash.xml:

  <item

     android:drawable="@color/colorPrimaryDark"/>

   <item>
      <bitmap
        android:gravity="center"
        android:src="@mipmap/image1"/>
   </item>

AndroidManifest.xml:

    <activity
      android:name=".SplashActivity"
      android:theme="@style/FullScreen">
    <intent-filter>
      <action android:name="android.intent.action.MAIN"/>

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

SplashActivity.java:

    public class SplashActivity extends AppCompatActivity {

    private static int SPLASH_TIME_OUT = 5000;

   @Override
   protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //setContentView(R.layout.activity_splash);

    new Handler().postDelayed(new Runnable() {

        @Override
        public void run() {
            Intent i = new Intent(SplashActivity.this,  MainActivity.class);
            startActivity(i);
            finish();
        }
        }, SPLASH_TIME_OUT);
       }
    }

I have the image1 with appropriate resolution/size present in the res folder. But the splash screen does not display the image covering full screen but displays with reduced size only some part of the screen. Can you please advice what needs to be done. I went through some of the suggestions present on some sites but it did not help.

Answer 1

In your res/drawable/background_splash.xml, change android:gravity you can use fill, in my case I used top|fill_horizontal for horizontal fill only, choose the combination you want.

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

   <item android:drawable="@color/White"/>

   <item>
       <bitmap
           android:gravity="top|fill_horizontal"
           android:src="@drawable/splash"/>
   </item>
</layer-list>

code for activity_splash.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
    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:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/colorAccent"
    tools:context=".SplashActivity">

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:srcCompat="@drawable/icon"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        />
</android.support.constraint.ConstraintLayout>

Code for Splash.java

import android.content.Intent;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class SplashActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getSupportActionBar().hide();
        setContentView(R.layout.activity_splash);
        Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                Intent i = new Intent(SplashActivity.this,MainActivity.class);
                startActivity(i);
                finish();
            }
        },2000);
    }
}

I have Done this program. Is this what you are looking for? this is your main XML

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res  
/android"
android:layout_width="match_parent"
android:background="@drawable/android"
android:layout_height="match_parent">

And mainActivity

 public class MainActivity extends AppCompatActivity {
// Splash screen timer
private static int SPLASH_TIME_OUT = 3000;

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

    new Handler().postDelayed(new Runnable() {

        /*
         * Showing splash screen with a timer. This will be useful when you
         * want to show case your app logo / company
         */

        @Override
        public void run() {
            // This method will be executed once the timer is over
            // Start your app main activity
            Intent i = new Intent(MainActivity.this, YourNextActivity.class);
            startActivity(i);

            // close this activity
            finish();
        }
    }, SPLASH_TIME_OUT);
}}

And Manifest

 <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"
                android:theme ="@android:style/Theme.Black.NoTitleBar.Fullscreen"/>

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

Answer 4

use parent of theme

parent="@style/Theme.AppCompat.Light.NoTitleBar.Fullscreen"
