我想你在显示矩阵网格上的问题已经解决了。您可能需要获取矩阵内容现在。试试这个

// SETUP YOUR GRIDVIEW
GridView mGridView = (GridView)findViewById(R.id.grid);
// COUNT TOTAL CHILDS IN IT
int gridchilds = mGridView.getChildCount();
// ITERATE THROUGH EACH CHILDS
for(int i = 0; i < gridchilds; i++) 
{
    // SELECT 'i' th CHILD IN A VIEWGROUP
    ViewGroup gridChild = (ViewGroup) mGridView.getChildAt(i);
    // GET THE CHILDREN SIZE OF THAT 'i' th CHILD
    int childSize = gridChild.getChildCount();
    // ITERATE THOUGH EACH
    for(int k = 0; k < childSize; k++) 
    {
        // CHECK IF IT IS AN 'EditText'
        if( gridChild.getChildAt(k) instanceof EditText)
        {
            // GET THE MATRIX VALUE AT THAT CELL
            String matrix_value=gridChild.getChildAt(k)).getText().toString();
        }
    }
}

希望有帮助

您可以通过使用RecyclerView和GridLayoutManager来实现它。
尝试下面的方法-但是我不确定最后一个方法的逻辑（在getValues()中）是否正确。你可能需要调整一下。
（看来你比我更熟悉数学，我就把它留给你了。））
希望能成功

RecyclerView rv = (RecyclerView) findViewById(your_recycler_view_id);
rv.setLayoutManager(new GridLayoutManager(context, COLUMN_COUNT, GridLayoutManager.VERTICAL, false));
rv.setAdapter(new YourCustomAdapter());

class YourCustomAdapter() {
    EditText[][] editTexts = new EditText[COLUMN_COUNT][ROW_COUNT];

    public YourCustomAdapter() {
    }

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(your_edit_text_layout, parent, false);
        return new YourViewHolder(view, listener);
    }

    @Override
    public void onBindViewHolder(final RecyclerView.ViewHolder h, int position) {
        YourViewHolder holder = (YourViewHolder) h;
        editTexts[position / COLUMN_COUNT][position % COLUMN_COUNT] = holder.editText;
    }

    @Override
    public int getItemCount() {
        return COLUMN_COUNT * ROW_COUNT;
    }

    private class YourViewHolder extends RecyclerView.ViewHolder {
        EditText editText;
        private YourViewHolder() {
            super(itemView);
            this.editText = itemView.findViewById(your_edit_text_id);
        }
    }

    public int[][] getValues() {
        int [][] values = new int[ROW_COUNT][COLUMN_COUNT];

        for(int i = 0; i < ROW_COUNT; i ++) {
            for(int j = 0; j < COLUMN_COUNT; j ++) {
                values[i][j] = 
                Integer.parseInt(editTexts[i][j].getText().toString());
            }
        }
    }
}
