一个关于安卓点击水波纹效果的工具类

public class AppAnimateUtil {


    public static void handleRippleBg(View rippleView, ColorStateList colorStateList, Context context, Drawable originalDrawable) {
     GradientDrawable gradientDrawable = new GradientDrawable();
        gradientDrawable.setColor(Color.parseColor("#33000000"));  // 设置形状的颜色
        gradientDrawable.setCornerRadius(UIUtils.dp2px(24f));  // 设置圆角半径
        RippleDrawable rippleDrawable = new RippleDrawable(colorStateList
                , originalDrawable, gradientDrawable);
        rippleView.setBackground(rippleDrawable);

}

使用

    private void initRipple() {
        int color = Color.parseColor("#DBE3EB");
        //设置ripple，5.0波纹效果
        AppAnimateUtil.handleRippleBg(ivBack, ColorStateList.valueOf(color),
                this, ivBack.getBackground());
        AppAnimateUtil.handleRippleBg(mIvSave, ColorStateList.valueOf(color),
                this, mIvSave.getBackground());
        AppAnimateUtil.handleRippleBg(mIvCopy, ColorStateList.valueOf(color),
                this, mIvCopy.getBackground());
    }
