国际象棋 - GridView，如何通过两次点击移动棋子？ [英] Chess - GridView , How to move chess piece by two clicks?

问题描述

我正在使用一个国际象棋应用程序，它从FEN Notations中加载国际象棋位置

我做了什么的基本信息。

我使用了64个Imageviews的Gridview，并将棋盘图像设置为Gridview的背景图像。我能够在Gridview中加载国际象棋位置。但我不知道如何将棋子从当前位置移动到第一次点击新位置（第二次点击）。但我有我的CustomAdapter的onclick两个职位。

我是android和gridview的新手

解决方案

我已经在MyApplication

中存储了两次点击的位置。 $ p> public class MyApplication extends Application {

private int ClickedImageView1 = -1;
private int ClickedImageView2 = -1;

private static MyApplication instance = new MyApplication（）;

// Getter-Setters
public static MyApplication getInstance（）{
return instance;
}
public static void setInstance（MyApplication instance）{
MyApplication.instance = instance;
}


public void setClickedImageView1（int ClickedImageView1）{
this.ClickedImageView1 = ClickedImageView1;
}

public int getClickedImageView1（）{
return ClickedImageView1;
}

public void setClickedImageView2（int ClickedImageView2）{
this.ClickedImageView2 = ClickedImageView2;
}

public int getClickedImageView2（）{
return ClickedImageView2;






$ b

同样在CustomAdapter类中，OnClickListener添加了一些代码

  public void onClick（View v）{
 
 
 if（MyApplication.getInstance（ ）.getClickedImageView1（）== -1）{
 MyApplication.getInstance（）。setClickedImageView1（position）; 
 //保存第一次点击位置，如果它是第一次点击
} 
 else {
 MyApplication.getInstance（）。setClickedImageView2（position）; 
 //保存第二次点击位置
 ImagesId [MyApplication.getInstance（）。getClickedImageView2（）] = ImagesId [MyApplication.getInstance（）。getClickedImageView1（）]; 
 //将图片移动到第二个位置
 ImagesId [MyApplication.getInstance（）。getClickedImageView1（）] = 0; //清除imageview1 
 gridView.setAdapter（new CustomAdapter（MainActivity.this，ImagesId））; //重新加载适配器
 // gridView.setBackgroundResource（R.drawable.chessboard）; 
 MyApplication.getInstance（）。setClickedImageView1（-1）; 
 MyApplication.getInstance（）。setClickedImageView2（-1）; 
 //重置MyApplication对象中的变量
} 
  

它正在工作！ !!

I am working with a chess app which loads chess position from FEN Notations

Basic information about what I did..

I used Gridview of 64 Imageviews and set chessboard image as a background image of Gridview.I able to load the chess position in Gridview.But I dont know how to move the chess piece from current location (first click) to new location (second click). but I have the two positions from onclick of my CustomAdapter.

I am new to android and gridview

解决方案

I have stored the position of two imageviews from two clicks in MyApplication
those I got from onclick.

 public class MyApplication extends Application {

    private int ClickedImageView1=-1;
    private int ClickedImageView2=-1;

private static MyApplication instance = new MyApplication();

// Getter-Setters
public static MyApplication getInstance() {
    return instance;
}
public static void setInstance(MyApplication instance) {
    MyApplication.instance = instance;
}


public void setClickedImageView1(int ClickedImageView1) {
    this.ClickedImageView1 = ClickedImageView1;
}

public int getClickedImageView1() {
    return ClickedImageView1;
}

public void setClickedImageView2(int ClickedImageView2) {
    this.ClickedImageView2 = ClickedImageView2;
}

public int getClickedImageView2() {
    return ClickedImageView2;
}
}

Also in the CustomAdapter class, in OnClickListener added some codes

  public void onClick(View v) {


                if (MyApplication.getInstance().getClickedImageView1()== -1) {
                    MyApplication.getInstance().setClickedImageView1(position);  
           //saving the first click position    if it is first click      
                }
                else {
                    MyApplication.getInstance().setClickedImageView2(position);  
        //saving the second click position                                               
                    ImagesId[MyApplication.getInstance().getClickedImageView2()]=ImagesId[MyApplication.getInstance().getClickedImageView1()]; 
              //moving image to secondclick position
                    ImagesId[MyApplication.getInstance().getClickedImageView1()]=0; //clear the imageview1
                    gridView.setAdapter(new CustomAdapter(MainActivity.this,ImagesId));     //reloads the adapter   
             // gridView.setBackgroundResource(R.drawable.chessboard);
                    MyApplication.getInstance().setClickedImageView1(-1);
                    MyApplication.getInstance().setClickedImageView2(-1);
                    //resetting the varibles in MyApplication object
                }

it is working!!!
