最近做项目需要用到表格,数据是动态指定的,本来用GridView是很方便的,可是老大不同意用这么重量级的控件,想办法吧。
做表格很容易想到用TableLayout,那就自定义一个来搞。
一、表格最蛋疼的就是那根线,网上有个很好的方法,大概思路是这样的:
1、给表格设置一个背景色(线的颜色)
2、给表格设置一个内边距(线的宽度的一半)
3、设置每一项内边距(线的宽度的一半)
3、给项的内容设置一个背景色(颜色不同于线即可)
显示效果大概是这样的:
二、数据的动态加载使用Adapter类,便与布局加载
自定义TableLayout加载的主体方法:
public void setAdapter(BaseAdapter baseAdapter, int column) { if (baseAdapter == null || baseAdapter.getCount() == 0) { return; } this.mAdapter = baseAdapter; this.column = column; drawLayout(); }
private void drawLayout() { removeAllViews(); int realcount = mAdapter.getCount(); int count = 0; if (realcount < column) { count = column; } else if (realcount % column != 0) { count = realcount + column - (realcount % column); } else { count = realcount; } TableRow tableRow = null;//每一行的TableRow for (int i = 0; i < count; i++) { final int index = i; View view = null; if (index >= realcount) { view = mAdapter.getView((realcount - 1), null, null); view.setVisibility(View.INVISIBLE); } else { view = mAdapter.getView(index, null, null); } if (index % column == 0) {// 整行 tableRow = new TableRow(mContext); } if (tableRow != null) {//添加每一个Item tableRow.addView(view); } if (index % column == 0) {// 整行 addView(tableRow, new TableLayout.LayoutParams( LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT)); } } }
三、使用和ListView的方式基本一样
public class MainActivity extends Activity { private List<Map<String, Object>> dataList; private TableBorderLayout layTable; private String[] datas = new String[] { "疯狂", "个性", "张扬", "抖擞", "加油", "奋斗", "努力", "精神" }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); initViews(); loadDatas(); } private void initViews() { layTable = (TableBorderLayout) findViewById(R.id.layTable); } private void loadDatas() { dataList = new ArrayList<Map<String, Object>>(); Map<String, Object> item = null; for (int i = 0; i < datas.length; i++) { item = new HashMap<String, Object>(); item.put("Title", datas[i]); dataList.add(item); } layTable.setAdapter(new MyAdapter(this, dataList)); } }
