I’m designing a simple game in an android based on the below picture

I have draw these squares by method drawLine() with screen size ratios

int r = 1; for (float i = rowHight; i <= canvasHight + rowHight; i += rowHight) {     if ((r % 2) != 0) {         canvas.drawLine(cellWidth / 2, i - rowHight, cellWidth / 2, i, paint);         for (float j = cellWidth; j < canvasWidth; j += cellWidth) {             canvas.drawLine(j + (cellWidth / 2), i - rowHight, j + (cellWidth / 2), i, paint);         }     } else if ((r % 2) == 0) {         for (float j = cellWidth; j < canvasWidth; j += cellWidth) {             canvas.drawLine(j, i - rowHight, j, i, paint);         }     }     canvas.drawLine(0, i, canvasWidth, i, paint);     r++; } 

how to design these boxes by arrays in Java in this way as the rows are not equal and also each row deviates from the next row because I want design this by arrays to handle the method onTouchEvent(MotionEvent event) >> The purpose of the question is how once I touch the screen how I know Which the box I touched it

I try to use two arrays every array include similar rows like this:

public void init() {          int c = 11;         int s1 = (c + 1) / 2;         int s2 = s1 - 1;          arr1 = new int[s1][];         arr2 = new int[s2][];          int x1 = 1;         for (int i = 0; i < (arr1.length / 2); i++) {             arr1[i] = new int[x1];             x1 += 2;         }          int x2 = s2;         for (int i = (arr1.length / 2); i < arr1.length; i++) {             arr1[i] = new int[x2];             x2 -= 2;         }          int y1 = 2;         for (int i = 0; i < ((arr2.length + 1) / 2); i++) {             arr2[i] = new int[y1];             y1 += 2;         }          int y2 = s2 - 1;         for (int i = ((arr2.length + 1) / 2); i < arr2.length; i++) {             arr2[i] = new int[y2];             y2 -= 2;         }           for (int row = 0; row < arr1.length; row++) {             for (int col = 0; col < arr1[row].length; col++) {                 arr1[row][col] = 0;             }         }          for (int row = 0; row < arr2.length; row++) {             for (int col = 0; col < arr2[row].length; col++) {                 arr2[row][col] = 0;             }         }     }
