Android上的棋盤

我正在使用8x8的網格佈局。對於每個正方形，我使用2個Imageview，一個用於正方形，一個用於該部分。下面是代碼：Android上的棋盤

activity_chess.xml：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:paddingBottom="@dimen/activity_vertical_margin" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 
tools:context=".ChessActivity" > 

<GridView 
    android:id="@+id/chessboard" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:background="#000000" 
    android:gravity="center_horizontal" 
    android:numColumns="8" > 
</GridView>

square.xml：

<?xml version="1.0" encoding="utf-8"?> 
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/square" 
    android:layout_width="35dp" 
    android:layout_height="35dp" 
    android:background="#000080" 
    android:orientation="vertical" > 

    <ImageView 
     android:id="@+id/square_background" 
     android:layout_width="35dp" 
     android:layout_height="35dp" /> 

    <ImageView 
     android:id="@+id/piece" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_gravity="center" /> 

</FrameLayout>

我的問題

每次我移動一塊而這一舉措是合法的，我重新加載了適配器gridlayout和它（我剛剛移動的那部分）消失了半秒鐘（我想適配器正在重新加載整個網格）。

我想這可能與解決方法的工作，如把一張圖片的頂部，直到適配器加載完成，但我想知道什麼，如果我做錯事的最佳解決方案。

下面是網格佈局的適配器代碼：

static class ViewHolder { 
    public ImageView square; 
    public ImageView piece;

public SquareAdapter(Context c, Piece[] listPiece, int turn) { 
    mContext = c;

     int action = event.getAction(); 

     FrameLayout fl2; 
     ImageView imgv2; 

     switch (event.getAction()) { 
     case DragEvent.ACTION_DRAG_STARTED: 
      //    Log.v("Test", "Entered start"); 
      break; 
     case DragEvent.ACTION_DRAG_ENTERED:

       lp[square.getCurrentSquare()] = currentPiece; 
       lp[currentPiece.getCurrentSquare()] = new Piece(); 

       if((yourBeingCheckedDumbAss(currentPiece)) 
         ||((destinationPiece instanceof King) 
           &&(destinationPiece.getColor() != currentPiece.getColor())) 
           ||(whiteTurn != currentPiece.getColor())){ 
        imgvcp.setImageResource(currentPiece.getRessource()); 
        imgvcp.setVisibility(View.VISIBLE); 
        lp[square.getCurrentSquare()] = destinationPiece; 
        lp[currentPiece.getCurrentSquare()] = currentPiece; 
       }else{ 
        imgvcp.setImageResource(currentPiece.getRessource()); 
        ((ChessActivity) mContext).setNewAdapter(lp); 
       } 

      }else{ 
       imgvcp.setVisibility(View.VISIBLE); 
      } 

      break; 
     case DragEvent.ACTION_DRAG_ENDED: 
     default: 
      break; 
     } 
     return true; 
    } 

    public boolean movementValid(){ 

     return false; 

    } 
} 


public boolean yourBeingCheckedDumbAss(Piece p){ 

    boolean isCheck = false; 

    int positionOfMyKing = 0; 


    for (int i = 0; i <= 63; i++){ 
     if ((lp[i].getColor()== p.getColor() 
       && (lp[i] instanceof King))){ 
      positionOfMyKing = i; 
     } 
    } 

    for (int i = 0; i <= 63; i++){ 
     if ((lp[i].getColor()!= -1) 
       && (lp[i].getColor()!= p.getColor())){ 
      if(lp[i].getPossibleMoves().contains(positionOfMyKing)){ 
       isCheck = true; 
      } 
     } 

    } 

    return isCheck; 



} 


}

這裏是ChessActivity.xml方法setNewAdapter：

public void setNewAdapter(Piece[] p){ 
    alp = p; 
    chessboardGridView.setAdapter(new SquareAdapter(this, p, whiteTurn)); 
    if (whiteTurn == 0){ 
     whiteTurn = 1; 
    }else{ 
     whiteTurn = 0; 
    } 

}

我會創建一個擴展視圖的新類。在onDraw中放幾行代碼繪製棋盤，並在某些數組中存儲關於遊戲所需的任何信息。這將繞過網格佈局和適配器。我看到你有一個工作解決方案。我建議自定義查看方式，因爲它的輕量級，並應通過更多的靈活性給你更多的青貯 – MikeHelland

而且也是一個很好的練習。會嘗試，謝謝。 –

這是我做的：只是不刷新適配器每次。我測試並將所有的東西放在拖放中，我剛剛爲網格佈局設置了一個新的適配器。它快得多。
