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androidapp，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：
publicclassDataGridViewextendsHorizontalScrollView{
privateList<DataGridViewColumn>columns;
privateList<Map<String,String>>rows;
privatebooleanhasHeader;
privateCellClickListenercellClickListener;
privateRowClickListenerrowClickListener;
privateRowValidatorListenerrowValidatorListener;
privateLinearLayoutheaderRow;
privateLinearLayoutbodyRow;
publicDataGridView(Contextcontext,AttributeSetattrs){
super(context,attrs);
TypedArraya=context.obtainStyledAttributes(attrs,R.styleable.DataGridView);
hasHeader=a.getBoolean(R.styleable.DataGridView_hasHeader,true);
a.recycle();
LayoutInflaterinflater=(LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
LinearLayoutcontainer=(LinearLayout)inflater.inflate(R.layout.ctrl_data_grid_view,null,false);
addView(container);
this.columns=newArrayList<DataGridViewColumn>();
this.rows=newArrayList<Map<String,String>>();
headerRow=newLinearLayout(getContext());
headerRow.setOrientation(LinearLayout.HORIZONTAL);
headerRow.setBackgroundResource(R.drawable.datagrid_header_background);
headerRow.setLayoutParams(newLayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.WRAP_CONTENT));
if(hasHeader){
container.addView(headerRow);
}
ScrollViewscrollView=(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);
}
publicvoidaddColumn(StringdataField,StringheaderText){

publicinterfaceRowClickListener{

代码里面用到的列属性类也附上：
publicclassDataGridViewColumn{
publicStringdataField;
publicStringheaderText;
publicintcolumnWidth;
publicinttextAlign;
publicinttextColor;
publicbooleanisEnabled;
}
