@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); this.setTitle("ListView自适应实现表格---hellogv"); lv = (ListView) this.findViewById(R.id.ListView01); ArrayList<TableRow> table = new ArrayList<TableRow>(); TableCell[] titles = new TableCell[5];// 每行5个单元 int width = this.getWindowManager().getDefaultDisplay().getWidth()/titles.length; // 定义标题 for (int i = 0; i < titles.length; i++) { titles[i] = new TableCell("标题" + String.valueOf(i), width + 8 * i, LayoutParams.FILL_PARENT, TableCell.STRING); } table.add(new TableRow(titles)); // 每行的数据 TableCell[] cells = new TableCell[5];// 每行5个单元 for (int i = 0; i < cells.length - 1; i++) { cells[i] = new TableCell("No." + String.valueOf(i), titles[i].width, LayoutParams.FILL_PARENT, TableCell.STRING); } cells[cells.length - 1] = new TableCell(R.drawable.icon, titles[cells.length - 1].width, LayoutParams.WRAP_CONTENT, TableCell.IMAGE); // 把表格的行添加到表格 for (int i = 0; i < 12; i++) table.add(new TableRow(cells)); TableAdapter tableAdapter = new TableAdapter(this, table); lv.setAdapter(tableAdapter); lv.setOnItemClickListener(new ItemClickEvent());
