如何从上到下然后从左到右填充GridLayout？

GridLayout gridLayout = findViewById(R.id.gridLayout);
int rowCount = n / m; // 计算行数
int columnCount = m; // 计算列数
gridLayout.setRowCount(rowCount); // 设置行数
gridLayout.setColumnCount(columnCount); // 设置列数

for (int i = 0; i < n; i++) {
    View view = createView(); // 创建需要添加的元素视图
    int row = i / columnCount; // 计算元素所在行
    int column = i % columnCount; // 计算元素所在列
    GridLayout.LayoutParams params = new GridLayout.LayoutParams();
    params.rowSpec = GridLayout.spec(row, 1); // 设置元素所在行
    params.columnSpec = GridLayout.spec(column, 1); // 设置元素所在列
    gridLayout.addView(view, params); // 添加元素到GridLayout
}
