Android combat aircraft game to achieve the protagonist and the protagonist related elements (3) _android

Look at the effect chart first

New Player Class

public class Player {private int playerhp = 3;
 Private Bitmap BMPPLAYERHP;
 Lead coordinates and bitmap private int x, y;
 Private Bitmap Bmpplayer;
 Lead moving speed private int speed = 5;

 Protagonist Mobile Logo Private Boolean isUp, Isdown, Isleft, isright;
  The constructor of the protagonist is public Player (Bitmap Bmpplayer, Bitmap bmpplayerhp) {this.bmpplayer = Bmpplayer;
  THIS.BMPPLAYERHP = BMPPLAYERHP;
  Aircraft initial position x = MYSURFACEVIEW.SCREENW/2-Bmpplayer.getwidth ()/2;
 y = Mysurfaceview.screenh-bmpplayer.getheight ();
  }//Lead game rendering method public void Draw (Canvas Canvas, Paint Paint) {//Draw lead Canvas.drawbitmap (Bmpplayer, x, Y, Paint); Draw the blood volume for (int i = 0; i < PLAYERHP i++) {canvas.drawbitmap (BMPPLAYERHP, I * bmpplayerhp.getwidth (), MyS
