首先我为 mini 2 制作应用程序并完美运行，但是当我尝试运行时，我想知道为什么我有一半的屏幕？，我得到的宽度值是 420？

WindowManager wm = (WindowManager) getApplicationContext().getSystemService(Context.WINDOW_SERVICE); // the results will be higher than using the activity context object or the getWindowManager() shortcut
      wm.getDefaultDisplay().getMetrics(displayMetrics);
wm.getDefaultDisplay().getMetrics(displayMetrics);
          lebar = displayMetrics.widthPixels;

当我尝试使用lebar = (int) displayMetrics.widthPixels * displayMetrics.densityDpi;

我逼近了

main.java

 private final void createGameBoard(Bitmap gambar) {
          board.once=true;
          tableLayout = (TableLayout) findViewById(R.id.TableLayout1);    
          tableLayout.removeAllViews();
          board = slidameBoard.createGameBoard(this, 
                gambar, 
                tableLayout,
                lebar,
                lebar,
                ukurangrid);
         board.setNumbersVisible(numbersVisible);
         gambar.recycle(); 
       }

第二个.java

public static slidameBoard createGameBoard(Context context, 
                                 Bitmap bitmap, 
                                 TableLayout parentLayout,
                                 int width,
                                 int height,
                                 int gridSize) {

      board = new slidameBoard(context, 
                       bitmap, 
                       parentLayout, 
                       width, 
                       height, 
                       gridSize);

      return board;
   }
