示例1: Draw
public override void Draw(Android.Graphics.Canvas canvas)
{
//base.Draw (canvas);
var box = Element as ExtendedFrame;
var rect = new Rect ();
var paint = new Paint () {
Color = box.BackgroundColor.ToAndroid (),
AntiAlias = true,
};
GetDrawingRect (rect);
canvas.DrawRoundRect (new RectF (rect), 100, 100, paint);
}示例2: Draw
/// <Docs>The Canvas to which the View is rendered.</Docs>
/// <summary>
/// BoxViewのカスタマイズはDrawで行う
/// </summary>
/// <param name="canvas">Canvas.</param>
public override void Draw(Android.Graphics.Canvas canvas)
{
// 2重に描画してしまうので、baseは描画しない
//base.Draw(canvas);
// ElementをキャストしてFormsで定義したCustomBoxViewを取得
var formsBox = (CustomBoxView)Element;
// Androidの描画はPaintを使用
using (var paint = new Paint())
{
// 塗りつぶし色の設定
paint.Color = formsBox.FillColor.ToAndroid();
// 吹き出し部分の設定
// パスの生成
var path = new Path();
// スタート地点の設定
path.MoveTo(0, 0);
// 経由地点の設定
path.LineTo(100, 10);
path.LineTo(100, 100);
// パスを繋げる
path.Close();
// 描画
canvas.DrawPath(path, paint);
// 角の丸い四角の設定
// 角丸の直径を決める
// widthとheightを比較して小さい方を基準にする
var minSize = Math.Min(Width, Height);
// 指定するのは直径なので、指定半径を2倍する
var diameter = formsBox.Radius * 2;
// 角丸の直径はminSize以下でなければならない
if (diameter > minSize)
diameter = minSize;
// 描画領域の設定
var rect = new RectF(0, 0, (float)Width, (float)Height);
//四角形描画
canvas.DrawRoundRect(rect, diameter, diameter, paint);
}
