android - 如何以编程方式使 TableRow 居中

Question

我以编程方式在表格行中创建了一些按钮，但它们总是左对齐。我怎样才能使整行居中？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

您可以简单地使用 Gravity 将行居中.只需使用

将其设置为您的行

row.setGravity(Gravity.CENTER_HORIZONTAL);
