如何在LibGDX中调整纹理大小？（Android）

Question

I'm starting to use LibGDX, and wanted to easily port my game to different screen size(in Android). I have a background texture, which I want to scale to the currently used resolution. The game works on 1920x1080, but when I use a lower resolution the texture is cut, how do I change it to the currently screen size?

I use

batch = new SpriteBatch();
bkTexture = new TextureRegion(new Texture(Gdx.files.internal("menu.png")),0 , 0, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());

and

Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
stage.act(delta);
batch.begin();
batch.draw(bkTexture, 0, 0, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());
batch.end();
stage.draw();

Answer 1

在纹理上添加滤镜？

myTexture.setFilter(TextureFilter.Linear, TextureFilter.Linear);

Answer 2

Try this:

bkTexture = new TextureRegion(new Texture(Gdx.files.internal("menu.png")),0 , 0);

instead of

bkTexture = new TextureRegion(new Texture(Gdx.files.internal("menu.png")),0 , 0, Gdx.graphics.getWidth(), Gdx.graphics.getHeight());

Using the 2nd line you extract a texture region with the size Gdx.graphics.getWidth(), Gdx.graphics.getHeight() at position 0,0 of the menu.png texture.
