截圖不會出現模糊情況，可以保證原圖效果。

public static Bitmap drawViewBitmap(View view, int scale) {
    Bitmap bitmap = Bitmap.createBitmap(view.getWidth() * scale, view.getHeight() * scale, Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);
    canvas.scale(scale, scale);
    view.draw(canvas);
    return bitmap;
}
