如何在表格布局中为每个单元格添加radiobutton

Question

我想为下面给出的表格中的每个单元格添加radiobuttons，并根据行和列获取它们的位置，如何实现它？请分享您的观点。提前致谢。我已经评论了我在每个单元格中添加文本的代码，可能在同一个地方我们可以添加radiobuttons

以下是工作代码：

public class MainActivity extends Activity {

    RelativeLayout rl;
    RadioGroup rg;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        String[] row = { "AA", "BB", "CC", "DD", "EE", "FF", "GG" };
        String[] column = { "Col 1", "Col 2", "Col 3", "Col 4", "Col 5", "Col 6" };
        int rl = row.length;
        int cl = column.length;

        Log.d("--", "R-Lenght--" + rl + "   " + "C-Lenght--" + cl);

        ScrollView sv = new ScrollView(this);
        TableLayout tableLayout = createTableLayout(row, column, rl, cl);
        HorizontalScrollView hsv = new HorizontalScrollView(this);

        hsv.addView(tableLayout);
        sv.addView(hsv);
        setContentView(sv);

    }

    public void makeCellEmpty(TableLayout tableLayout, int rowIndex, int columnIndex) {
        // get row from table with rowIndex
        TableRow tableRow = (TableRow) tableLayout.getChildAt(rowIndex);

        // get cell from row with columnIndex
        TextView textView = (TextView) tableRow.getChildAt(columnIndex);

        // make it black
        textView.setBackgroundColor(Color.BLACK);
    }

    public void setHeaderTitle(TableLayout tableLayout, int rowIndex,
            int columnIndex) {

        // get row from table with rowIndex
        TableRow tableRow = (TableRow) tableLayout.getChildAt(rowIndex);

        // get cell from row with columnIndex
        TextView textView = (TextView) tableRow.getChildAt(columnIndex);

        textView.setText("Hello");
    }

    private TableLayout createTableLayout(String[] rv, String[] cv,
            int rowCount, int columnCount) {
        // 1) Create a tableLayout and its params
        TableLayout.LayoutParams tableLayoutParams = new TableLayout.LayoutParams();
        TableLayout tableLayout = new TableLayout(this);
        tableLayout.setBackgroundColor(Color.BLACK);

        // 2) create tableRow params
        TableRow.LayoutParams tableRowParams = new TableRow.LayoutParams();
        tableRowParams.setMargins(1, 1, 1, 1);
        tableRowParams.weight = 1;

        for (int i = 0; i < rowCount; i++) {
            // 3) create tableRow
            TableRow tableRow = new TableRow(this);
            tableRow.setBackgroundColor(Color.BLACK);

            final RadioButton[] rb = new RadioButton[10];
            rl=(RelativeLayout) findViewById(R.id.rl);
            rg=new RadioGroup(this);

            for (int j = 0; j < columnCount; j++) {
                // 4) create textView
                TextView textView = new TextView(this);
                // textView.setText(String.valueOf(j));
                textView.setBackgroundColor(Color.WHITE);
                textView.setGravity(Gravity.CENTER);

                String s1 = Integer.toString(i);
                String s2 = Integer.toString(j);
                String s3 = s1 + s2;
                int id = Integer.parseInt(s3);
                Log.d("TAG", "-___>" + id);




                if (i == 0 && j == 0) {
                    textView.setText("0==0");
                } else if (i == 0) {
                    Log.d("TAAG", "set Column Headers");
                    textView.setText(cv[j - 1]);
                } else if (j == 0) {
                    Log.d("TAAG", "Set Row Headers");
                    textView.setText(rv[i - 1]);
                } else {
                    /*textView.setText("" + id);
                    // check id=23
                    if (id == 23) {
                        textView.setText("ID=23");

                    }*/


                    //Add Radiobuttons here
                }

                // 5) add textView to tableRow
                tableRow.addView(textView, tableRowParams);

            }

            // 6) add tableRow to tableLayout
            tableLayout.addView(tableRow, tableLayoutParams);
        }

        return tableLayout;
    }

}

Answer 1

请使用listview而不是表格布局

   ListView listView = (ListView) view.findViewById(R.id.listview);

 // values is a StringArray holding some string values.
CustomAdapter customAdapter = new CustomAdapter (getActivity(), values);
listView.setAdapter(customAdapter );

Answer 2

使用单选按钮或组的多维数组或任何你想要的......

RadioButton[][] rb = new RadioButton[][];

使用上面的语句来声明它并访问它使用两个嵌套的循环。一个循环嵌套在另一个循环中。

for(int i=0;i<=5;i++)
{
    for (int j=0;j<=5;j++)
    {
         rb[i][j] = new RadioButton(this);
    }
}
