libgdx my splashscreen is not showing

I'm writing an libgdx game, but it seems that i cannot show my splashscreen, it only shows a black screen. does anyone know how this comes?

I don't get any runtime error, it only shows a blackscreen, even if i set the glClearColor to an other color then black

package mygame;



import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.Screen;
import com.badlogic.gdx.graphics.GL10;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.Texture.TextureFilter;
import com.badlogic.gdx.graphics.g2d.Sprite;  
import com.badlogic.gdx.graphics.g2d.SpriteBatch;

 public class SplashScreen implements Screen {

Texture splashTexture;
Sprite splashSprite;
SpriteBatch batch;
MyGame game;

public SplashScreen(MyGame game) {
    this.game = game;
}

@Override
public void render(float delta) {
    Gdx.gl.glClearColor(0, 0, 0, 1);
    Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);

    batch.begin();
    splashSprite.draw(batch);
    batch.end();
}

@Override
public void resize(int width, int height) {

}

@Override
public void show() {
    splashTexture = new Texture("mygame/splash.png");
    splashTexture.setFilter(TextureFilter.Linear, TextureFilter.Linear);

    splashSprite = new Sprite(splashTexture);
    //splashSprite.setColor(1, 1, 1, 0);
    splashSprite.setX(Gdx.graphics.getWidth() / 2 - (splashSprite.getWidth() / 2));
    splashSprite.setY(Gdx.graphics.getHeight() / 2 - (splashSprite.getHeight() / 2));

    batch = new SpriteBatch();
}

@Override
public void hide() {

}

@Override
public void pause() {

}

@Override
public void resume() {

}

@Override
public void dispose() {

}

}

This is how your game class should look like...you need to call the super functions .

package com.sample;

import com.badlogic.gdx.Game;

public class Sample extends Game{

    @Override
    public void dispose() {
        // TODO Auto-generated method stub
        super.dispose();
    }

    @Override
    public void pause() {
        // TODO Auto-generated method stub
        super.pause();
    }

    @Override
    public void resume() {
        // TODO Auto-generated method stub
        super.resume();
    }

    @Override
    public void render() {
        // TODO Auto-generated method stub
        super.render();
    }

    @Override
    public void resize(int width, int height) {
        // TODO Auto-generated method stub
        super.resize(width, height);
    }

    @Override
    public void create() {
        // TODO Auto-generated method stub
        setScreen(new AnotherScreen(this));
    }

}

I tried your code (see below) and it works well enough, so perhaps the problem lies in the MyGame class. Are you, for example, overriding Game.render() then not calling super.render()?

package hacks;

import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.Screen;
import com.badlogic.gdx.backends.lwjgl.LwjglApplication;
import com.badlogic.gdx.backends.lwjgl.LwjglApplicationConfiguration;
import com.badlogic.gdx.graphics.GL10;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.Texture.TextureFilter;
import com.badlogic.gdx.graphics.g2d.Sprite;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;

public class MyGame extends com.badlogic.gdx.Game {

    @Override
    public void create() {
        setScreen(new SplashScreen(this));
    }

    public static void main(String[] args) {
        LwjglApplicationConfiguration config = new LwjglApplicationConfiguration();

        config.title = MyGame.class.getName();
        config.width = 800;
        config.height = 480;
        config.fullscreen = false;
        config.useGL20 = true;
        config.useCPUSynch = true;
        config.forceExit = true;
        config.vSyncEnabled = true;

        new LwjglApplication(new MyGame(), config);
    }
}

class SplashScreen implements Screen {

    Texture splashTexture;
    Sprite splashSprite;
    SpriteBatch batch;
    MyGame game;

    public SplashScreen(MyGame game) {
        this.game = game;
    }

    @Override
    public void render(float delta) {
        Gdx.gl.glClearColor(0, 0, 0, 1);
        Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT);

        batch.begin();
        splashSprite.draw(batch);
        batch.end();
    }

    @Override
    public void resize(int width, int height) {
    }

    @Override
    public void show() {
        splashTexture = new Texture("assets/data/libgdx.png");
        splashTexture.setFilter(TextureFilter.Linear, TextureFilter.Linear);

        splashSprite = new Sprite(splashTexture);
        // splashSprite.setColor(1, 1, 1, 0);
        splashSprite.setX(Gdx.graphics.getWidth() / 2 - (splashSprite.getWidth() / 2));
        splashSprite.setY(Gdx.graphics.getHeight() / 2 - (splashSprite.getHeight() / 2));

        batch = new SpriteBatch();
    }

    @Override
    public void hide() {

    }

    @Override
    public void pause() {

    }

    @Override
    public void resume() {

    }

    @Override
    public void dispose() {
    }
}
