我做了这个例子,希望对你有帮助。
TableLayout table = (TableLayout)findViewById(R.id.table_id_in_xml);
TableRow row = new TableRow(this);
TableRow row2 = new TableRow(this);
TextView col1, col2, col3;
row.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
row2.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
col1 = new TextView(this);
col2 = new TextView(this);
col3 = new TextView(this);
col1.setText("col1");
col2.setText("col2");
col3.setText("col3");
row.addView(col1);
row.addView(col2);
row.addView(col3);
table.addView(row, new TableLayout.LayoutParams( LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
//HERE IS WHAT YOU NEED
TableRow.LayoutParams params = (TableRow.LayoutParams) row2.getLayoutParams();
params.span = 3; //amount of columns you will span
col1 = new TextView(this);
col1.setText("span on col1 makes it bigger than the others");
col1.setLayoutParams(params);
row2.addView(col1);
table.addView(row2, new TableLayout.LayoutParams( LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
