Question

我正在以编程方式在表格行中创建多个按钮，但它们总是以左对齐方式结束。我怎样才能将整行排成一行？我正在尝试创建每一行：

TableRow row = new TableRow(getActivity());
TableLayout.LayoutParams params = new TableLayout.LayoutParams(TableLayout.LayoutParams.MATCH_PARENT, TableLayout.LayoutParams.WRAP_CONTENT, Gravity.CENTER_HORIZONTAL);
row.setLayoutParams(params);

for (int j = 0; j != numButtonCols; j++) {
    Button b = new Button(getActivity());
    b.setOnClickListener(actionListener);
    row.addView(b);
    actionButtons[j][i] = b;
}

layout.addView(row);

Answer 1

您只需使用Gravity将行居中。只需使用

将其设置为您的行

isInterrupted()

Answer 2

试试这个：

    TableRow row = new TableRow(getActivity());
    TableLayout.LayoutParams params = new TableLayout.LayoutParams(TableLayout.LayoutParams.MATCH_PARENT, TableLayout.LayoutParams.WRAP_CONTENT, Gravity.CENTER_HORIZONTAL);
    row.setLayoutParams(params);

    TableRow.LayoutParams buttonParams = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT, Gravity.CENTER_HORIZONTAL);

    for (int j = 0; j != numButtonCols; j++) {
        Button b = new Button(getActivity());
        b.setLayoutParams(buttonParams);
        b.setOnClickListener(actionListener);
        row.addView(b);
        actionButtons[j][i] = b;
    }

layout.addView(row);
