Android自定义DataGridView数据表格控件

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

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：

public class DataGrIDVIEw extends horizontalscrollview { private List<DataGrIDVIEwColumn> columns; private List<Map<String,String>> rows; private boolean hasheader; private CellClickListener cellClickListener; private RowClickListener rowClickListener; private RowValIDatorListener rowValIDatorListener; private linearLayout headerRow; private linearLayout bodyRow; public DataGrIDVIEw(Context context,AttributeSet attrs) {  super(context,attrs);

 linearLayout container = (linearLayout) inflater.inflate(R.layout.ctrl_data_grID_vIEw,null,false);  addVIEw(container);  this.columns = new ArrayList<DataGrIDVIEwColumn>();  this.rows = new ArrayList<Map<String,String>>();   headerRow = new linearLayout(getContext());   headerRow.setorIEntation(linearLayout.HORIZONTAL);   headerRow.setBackgroundResource(R.drawable.datagrID_header_background);   headerRow.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT));  if (hasheader){   container.addVIEw(headerRow);  }  ScrollVIEw scrollVIEw = (ScrollVIEw)inflater.inflate(R.layout.ctrl_data_grID_vIEw_scroll,container,false);  bodyRow = (linearLayout) inflater.inflate(R.layout.ctrl_data_grID_vIEw,scrollVIEw,false);  scrollVIEw.addVIEw(bodyRow);  container.addVIEw(scrollVIEw); } public voID addColumn(String datafield,String headerText){  this.addColumn(datafield,headerText,200); } public voID addColumn(String datafield,String headerText,int columnWIDth){  this.addColumn(datafield,columnWIDth,Gravity.START);

     }     }    });   } else {    rowFIEldText.setTextcolor(color.rgb(128,128,128));   }  }  if (rowValIDatorListener != null){   rowValIDatorListener.onValIDator(daTarow,row);  }  if (index == -1){   bodyRow.addVIEw(daTarow);

} public interface RowClickListener{  voID onClick(Map<String,String> rowData); } public interface RowValIDatorListener{  voID onValIDator(VIEwGroup v,Map<String,String> rowData); }}

代码里面用到的列属性类也附上：

public class DataGrIDVIEwColumn { public String datafield; public String headerText; public int columnWIDth; public int textAlign; public int textcolor; public boolean isEnabled;}
