Android uses LIBGDX to implement the method of controlling role movement of analog key _android

This article is an example of how Android uses LIBGDX to implement a simulation key to control role movement. Share to everyone for your reference, specific as follows:

Package Com.demo;
Import Android.os.Bundle;
Import com.badlogic.gdx.backends.android.AndroidApplication;
LIBGDX's texture and sprite use public
class Libgdxactivity extends Androidapplication {public
  void OnCreate ( Bundle Bundle) {
    super.oncreate (Bundle);
    Initialize the game screen and set whether to support Gles 2.0, if you have no need to choose true for backward compatibility (more than 2.1), otherwise choose false.
//   Initialize (new Firstgame (), true);
    Initialize (new Box2ddemo (), true);
  }

Package Com.demo;
Import COM.BADLOGIC.GDX.GDX;
Import Com.badlogic.gdx.graphics.Texture;
Import Com.badlogic.gdx.graphics.g2d.SpriteBatch;
Import Com.badlogic.gdx.scenes.scene2d.Actor;
  public class Firstactor extends actor{private texture texture;
  @Override public void Draw (SpriteBatch batch, float arg1) {batch.draw (texture, this.x, this.y); @Override public Actor hit (float arg0, float arg1) {if (x > 0 && y > 0 && this.height ;
    Y && this.width > x) {return this;
    else {return null;
    @Override public boolean touchdown (float arg0, float arg1, int arg2) {//TODO auto-generated method stub
  return false;
  @Override public void touchdragged (float arg0, float arg1, int arg2) {//TODO auto-generated method stub} @Override public void TouchUp (float arg0, float arg1, int arg2) {//TODO auto-generated method stub} public Fi
   Rstactor (String name) {super (name); Texture = new Texture (Gdx.files.internal ("bt.png"));
    This.height = Texture.getheight ();
  This.width = Texture.getwidth ();

 }
}
