Android Write 2048 Games _android

Let's say 2048 game rules:

At the beginning, there are two numbers randomly appearing in the chessboard, which can only be 2 or 4.

Players can choose from top to bottom four directions, if the number in the chessboard appears to shift or merge, as effective mobile

In the direction of the player's choice, if the same number is merged, each effective move can be merged at the same time, but cannot be merged continuously.

All new generated numbers that are merged are added as valid scores for that step

The player chooses the direction row or column front has the space to appear the displacement

Every effective move one step, the space of the chessboard (no number) randomly appears a number (still may be 2 or 4)

The chessboard is filled with numbers, unable to move effectively, negative, game over

2048 on board, award wins, game over

The following code

Mainactivity class

public class Mainactivity extends Appcompatactivity {

 @Override
 protected void OnCreate (Bundle Savedinstancestate) {
 super.oncreate (savedinstancestate);
 Setcontentview (New Gameview (this));
 }

Define a card class to display data

/card type public class cards extends Framelayout {//2 TextView TV;
 private int number = 0;

 int width;
 Public card (context, int-width) {super (context);
 This.width = width;
 Init ();
 private void Init () {TV = new TextView (GetContext ());
 Setpadding (5, 5, 5, 5);
 Framelayout.layoutparams LP = new Layoutparams (width-10, width-10);
 TV.SETLAYOUTPARAMS (LP);
 Tv.setgravity (Gravity.center);
 Tv.settextcolor (Color.White);
 Tv.settextsize (48);
 This.addview (TV);
 SetColor ();
 public void Setnumber (int number) {this.number = number;
 if (number = = 0) tv.settext ("");
 else Tv.settext (number + "");
 SetColor (); 
  @Override public String toString () {return "card{" + "tv=" + TV + ", number=" + number + ", width=" + width +
 '}';
  private void SetColor () {switch (number) {Case 0:tv.setbackgroundcolor (getresources (). GetColor (R.COLOR.C0));
  Break
  Case 2:tv.setbackgroundcolor (Getresources (). GetColor (R.COLOR.C2));
  Break Case 4:TV. SetBackgroundColor (Getresources (). GetColor (r.color.c4));
  Break
  Case 8:tv.setbackgroundcolor (Getresources (). GetColor (R.COLOR.C8));
  Break
  Case 16:tv.setbackgroundcolor (Getresources (). GetColor (R.COLOR.C16));
  Break
  Case 32:tv.setbackgroundcolor (Getresources (). GetColor (R.COLOR.C32));
  Break
  Case 64:tv.setbackgroundcolor (Getresources (). GetColor (R.COLOR.C64));
  Break
  Case 128:tv.setbackgroundcolor (Getresources (). GetColor (r.color.c128));
  Break
  Case 256:tv.setbackgroundcolor (Getresources (). GetColor (r.color.c256));
  Break
  Case 512:tv.setbackgroundcolor (Getresources (). GetColor (r.color.c512));
  Break
  Case 1024:tv.setbackgroundcolor (Getresources (). GetColor (r.color.c1024));
  Break
  Case 2048:tv.setbackgroundcolor (Getresources (). GetColor (r.color.c2048));
 Break
 } public int GetNumber () {return number;
 }

}

Define some of the above colors in the colors of values

<?xml version= "1.0" encoding= "Utf-8"?>
<resources>
 <color name= "Colorprimary" > #3F51B5 </color>
 <color name= "Colorprimarydark" > #303F9F </color>
 <color name= "Coloraccent" > #FF4081 </color>

 <color name= "C0" > #43382a </color>
 <color name= "C2" > #2a8618 </color>
 <color name= "C4" > #3d6319 </color>
 <color name= "C8" > #F2B179 </color>
 <color name= "C16" > #F59563 </color>
 <color name= "C32" > #F57C5F </color>
 < Color Name= "C64" > #5b69b7 </color>
 <color name= "C128" > #b37d3e </color>
 <color Name = "c256" > #3a9096 </color>
 <color name= "c512" > #d7882c </color>
 <color name= "c1024" > #5c1b78 </color>

</resources>
