Android custom DataGridView data table control and android custom control

Android custom DataGridView data table control and android custom control

I am a. net programmer, but I am suffering from the company's requirement to develop an android app. I can't help but stick to my head.

Since data display controls (similar to. net DataGridView) are needed in many parts of the project, du Niang finds that no similar controls are made public, so she cannot write them by herself.

Paste the Code directly:

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);        TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.DataGridView);        hasHeader = a.getBoolean(R.styleable.DataGridView_hasHeader, true);        a.recycle();        LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);        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, headerText, columnWidth, Gravity.START);

The column attribute classes used in the Code are also attached:

public class DataGridViewColumn {    public String dataField;    public String headerText;    public int columnWidth;    public int textAlign;    public int textColor;    public boolean isEnabled;}
