円の代わりにアンドロイドアプリで四角形のジェネレートを作成する方法

Question

こんにちは私は四角形としてフォルダを表示しようとしていますが、グリッドビューで最初の4つのアプリのアイコンを表示するアンドロイドランチャーに取り組んでいます私はその理由> clipp.addCircle（iconSize/2、iconSize/ 2、iconSize/2と考える

    @Override 
    public void setAlpha(int i) {} 

    @Override 
    public void setColorFilter(ColorFilter colorFilter) {} 

    @Override 
    public int getOpacity() {return 0;} 
} 

：それは...円形として

HERESに私のコードを示しています-outlinepad、> Path.Direction.CW）;コードですが、わかりません

円ではなく正方形にするにはどうすればよいですか？

ありがとうございます！

Answer 1

addRect(float left, float top, float right, float bottom, Path.Direction dir)

する addCircleからあなた clippパスの使用率を変更
