Yazılımla ilgili olarak setLayerType ile ClipPath

Question

Özel görünümümde bir yol izlemeye çalışıyorum ancak siyah renkli görünüyor. Aynı sebep için arama ve bulma yoluyla. "setLayerType(LAYER_TYPE_SOFTWARE,null)" ayarlamam gerektiğini öğrendim. Bundan sonra mükemmel görünür ancak bazı deivislerde çöker.

Crash Günlüğü (cihazlara göre Bunlardan biri):

1. java.lang.NegativeArraySizeException

2. Bitmap 32bit aşıyor

Sen böyle bir şey yapmak mı manzaralı bir pencere oluşturmak.

public class ClippedImageView extends ImageView { 
    private Paint mPaint; 
    private Path mPath; 

    public ClippedImageView(Context context) { 
     this(context, null); 
     init(); 
    } 

    public v(Context context, AttributeSet attrs) { 
     this(context, attrs, 0); 
     init(); 
    } 

    public ClippedImageView(Context context, AttributeSet attrs, int defStyleAttr) { 
     super(context, attrs, defStyleAttr); 
     init(); 
    } 

    private void init() { 
     mPaint = new Paint(Paint.ANTI_ALIAS_FLAG); 
     mPaint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.CLEAR)); 
     mPath = new Path(); 
     RectF rect = new RectF(0, 0, 100, 100); 
     mPath.addArc(rect, 270, 180); 
    } 

    @Override 
    protected void onDraw(Canvas canvas) { 
     canvas.clipPath(mPath, Region.Op.DIFFERENCE); 
     super.onDraw(canvas); 
    } 
}
