android 怎么绘制表格边框

Answer 1

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));
}
}
