可以去dribbble上看看原生效果。

好的app在功能完善的基础上，从细节上吸引用户。虽然点赞这个功能点已经很普遍了，但是千篇一律的生硬效果让这么神圣的操作显得很黯淡(扯淡了，不就是赞赞赞么...)，当然也有非常炫酷的，忍不住多点几次赞的效果。比如twitter的点赞。就不码字扯淡了，上图上源码

使用Path画爱心

Path path = new Path();

path.moveTo((float) (0.5 * realWidth) + rectFlove.left, (float) (0.17 * realHeight) + rectFlove.top);

path.cubicTo((float) (0.15 * realWidth) + rectFlove.left, (float) (-0.35 * realHeight + rectFlove.top),

(float) (-0.4 * realWidth) + rectFlove.left, (float) (0.45 * realHeight) + rectFlove.top,

(float) (0.5 * realWidth) + rectFlove.left, (float) (realHeight * 0.8 + rectFlove.top));

// path.moveTo( (float) (0.5 * realWidth) + rectFlove.left, (float) (realHeight * 0.8 + rectFlove.top));

path.cubicTo((float) (realWidth + 0.4 * realWidth) + rectFlove.left, (float) (0.45 * realHeight) + rectFlove.top,

(float) (realWidth - 0.15 * realWidth) + rectFlove.left, (float) (-0.35 * realHeight) + rectFlove.top,

(float) (0.5 * realWidth) + rectFlove.left, (float) (0.17 * realHeight) + rectFlove.top);

path.close();

取消时候爱心出现裂痕然后分成两半分别向左右倾斜,使用** canvas**

rotate来旋转达到倾斜效果

mBitmapBrokenLeftLove = Bitmap.createBitmap(getMeasuredWidth(), (int) lastY, Bitmap.Config.ARGB_8888);

canvas = new Canvas(mBitmapBrokenLeftLove);

canvas.rotate(-1*mBrokenAngle * mAnimatedBrokenValue, lastX, lastY);

Path path = new Path();

path.moveTo((float) (0.5 * realWidth) + rectFlove.left, (float) (0.17 * realHeight) + rectFlove.top);

path.cubicTo((float) (0.15 * realWidth) + rectFlove.left, (float) (-0.35 * realHeight + rectFlove.top),

(float) (-0.4 * realWidth) + rectFlove.left, (float) (0.45 * realHeight) + rectFlove.top,

(float) (0.5 * realWidth) + rectFlove.left, (float) (realHeight * 0.8 + rectFlove.top));

path.lineTo(thirdX, thirdY);

path.lineTo(secondX, secondY);

path.close();

canvas.drawPath(path, mPaintLike);

Gradle

compile 'com.ldoublem.thumbUplib:ThumbUplib:0.2'

Usage xml

android:id="@+id/tpv"

android:layout_width="50dp"

android:layout_height="50dp"

app:cracksColor="#33475f"

app:edgeColor="#9d55b8"

app:fillColor="#ea8010"

app:unlikeType="1"

/>

mThumbUpView.setCracksColor(Color.rgb(22, 33, 44));

mThumbUpView.setFillColor(Color.rgb(11, 200, 77));

mThumbUpView.setEdgeColor(Color.rgb(33, 3, 219));

mThumbUpView.setOnThumbUp(new ThumbUpView.OnThumbUp() {

@Override

public void like(boolean like) {

}

});

mThumbUpView.Like();

mThumbUpView.UnLike();

如果觉得还可以，给颗小星星^^
