Android 自定义DataGridView数据表格控件

我是一个.net程序员，但是苦于公司要求开发一个android app，没办法，只能硬着头皮上了。

由于项目里面很多地方需要用到数据显示控件（类似于.net的DataGridView），度娘找了下发现没人公开类似的控件，没办法只好自己写了。

废话不多说，直接贴代码：

  1 public class DataGridView extends HorizontalScrollView {
  2     private List<DataGridViewColumn> columns;
  3     private List<Map<String,String>> rows;
  4 
  5     private boolean hasHeader;
  6 
  7     private CellClickListener cellClickListener;
  8     private RowClickListener rowClickListener;
  9     private RowValidatorListener rowValidatorListener;
 10     private LinearLayout headerRow;
 11     private LinearLayout bodyRow;
 12 
 13     public DataGridView(Context context, AttributeSet attrs) {
 14         super(context, attrs);
 15         TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.DataGridView);
 16         hasHeader = a.getBoolean(R.styleable.DataGridView_hasHeader, true);
 17         a.recycle();
 18 
 19         LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
 20         LinearLayout container = (LinearLayout) inflater.inflate(R.layout.ctrl_data_grid_view, null, false);
 21         addView(container);
 22         this.columns = new ArrayList<DataGridViewColumn>();
 23         this.rows = new ArrayList<Map<String,String>>();
 24          headerRow = new LinearLayout(getContext());
 25          headerRow.setOrientation(LinearLayout.HORIZONTAL);
 26          headerRow.setBackgroundResource(R.drawable.datagrid_header_background);
 27          headerRow.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT));
 28         if (hasHeader){
 29             container.addView(headerRow);
 30         }
 31         ScrollView scrollView = (ScrollView)inflater.inflate(R.layout.ctrl_data_grid_view_scroll, container, false);
 32         bodyRow = (LinearLayout) inflater.inflate(R.layout.ctrl_data_grid_view, scrollView, false);
 33         scrollView.addView(bodyRow);
 34         container.addView(scrollView);
 35     }
 36

代码里面用到的列属性类也附上：

1 public class DataGridViewColumn {
2     public String dataField;
3     public String headerText;
4     public int columnWidth;
5     public int textAlign;
6     public int textColor;
7     public boolean isEnabled;
8 }
