这是 Surface View 和 View 中抗锯齿的测试项目,
在视图中:(这对抗锯齿非常有用)
@Override
protected void onDraw(Canvas canvas) {
Paint p = new Paint();
p.setColor(Color.WHITE);
canvas.setDrawFilter(new PaintFlagsDrawFilter(0, Paint.ANTI_ALIAS_FLAG|Paint.FILTER_BITMAP_FLAG));
canvas.drawColor(Color.BLACK);
Matrix mMatrix = new Matrix();
mMatrix.postScale(0.34f, 0.34f);
canvas.drawBitmap(mBitmap, mMatrix, p);
canvas.drawText("View Anti alias", 100, 300, p);
}
在表面视图中:(丑陋-_-!!)
public void doDraw(Canvas canvas) {
Paint p = new Paint();
p.setColor(Color.WHITE);
canvas.setDrawFilter(new PaintFlagsDrawFilter(0, Paint.ANTI_ALIAS_FLAG | Paint.FILTER_BITMAP_FLAG));
canvas.drawColor(Color.BLACK);
Matrix mMatrix = new Matrix();
mMatrix.postScale(0.34f, 0.34f);
canvas.drawBitmap(mBitmap, mMatrix, p);
canvas.drawText("Surface View Anti alias", 100, 300, p);
}

任何人都可以告诉我如何在 surfaceView 中消除别名?
