细胞高度＆amp;宽度根据文字大小而变化。我需要将所有单元格大小固定。

XML代码

    <LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
            android:id="@+id/main"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"                                 
            android:orientation="vertical"  
            android:weightSum="100"  >
 </LinearLayout>

我的代码是

Main = (LinearLayout) findViewById(R.id.main);

    Main_1 = new LinearLayout(this);
    LinearLayout.LayoutParams sudoku_1_lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,LinearLayout.LayoutParams.FILL_PARENT);
    Main_1.setLayoutParams(sudoku_1_lp);
    Main_1.setWeightSum(100);
    Main_1.setOrientation(LinearLayout.VERTICAL);
    Main_1.setId(100);

    //Layout for sudoku_board 
    sudokuboard = new LinearLayout(this);
    LinearLayout.LayoutParams sudokuboard_lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,0,80.0f);
    sudokuboard_lp.setMargins(1, 1, 1, 1);
    sudokuboard.setLayoutParams(sudokuboard_lp);
    sudokuboard.setWeightSum(80);
    sudokuboard.setOrientation(LinearLayout.VERTICAL);
    sudokuboard.setBackgroundColor(Color.parseColor("#FF0000"));
    sudokuboard.setId(102);

    tblsudoku = new TableLayout(this);
    TableLayout.LayoutParams sudoku_tbl_lp = new TableLayout.LayoutParams(TableLayout.LayoutParams.FILL_PARENT,TableLayout.LayoutParams.FILL_PARENT,80.0f);
    sudoku_tbl_lp.setMargins(2, 2, 2, 2);
    tblsudoku.setLayoutParams(sudoku_tbl_lp);
    tblsudoku.setId(103);

    for(int i=0; i < 9; i++)
    {
            TableRow NewRow1 =new TableRow(this);

            TableLayout.LayoutParams n1 = new TableLayout.LayoutParams(TableLayout.LayoutParams.FILL_PARENT,0,10.0f);
            if(i==3 || i==6  )
            {
                n1.setMargins(0,2, 0, 0);
            }
            else
            {
                n1.setMargins(0,1, 0, 0);
            }

            NewRow1.setLayoutParams(n1);

            for(int j=0; j<9; j++)
            {
                TextView tv_00 = new TextView(this);
                int id=10*i;
                id=id+j;
                id=id*id*id;
                String strText=""+id;

                tv_00.setText(strText);
                TableRow.LayoutParams r1 = new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT,TableRow.LayoutParams.FILL_PARENT, 10.0f);
                if(j==2 || j==5  )
                {
                    r1.setMargins(0, 0, 2, 0);
                }
                else
                {
                    r1.setMargins(0, 0, 1, 0);
                }

                tv_00.setLayoutParams(r1);
                tv_00.setGravity(Gravity.CENTER);                   
                tv_00.setBackgroundColor(Color.GREEN);
                tv_00.setId(id);
                tv_00.setPadding(2, 2, 2, 2);

                NewRow1.addView(tv_00);
            }
            tblsudoku.addView(NewRow1);
    }
    sudokuboard.addView(tblsudoku); 
    Main_1.addView(sudokuboard);
    Main.addView(Main_1);

首先使用任何算法在你的布局中获得最大可能的数字然后相应地决定布局参数并将其设置为textview。

int anywidth = 0; //Decide according to possible max text length 
int anyheight = 0; //Decide according to passible max text length
TableRow.LayoutParams r1 = new TableRow.LayoutParams(anywidth, anyheight, 10.0f);
