可以去dribbble上看看原生效果。

好的app在功能完善的基礎(chǔ)上，從細節(jié)上吸引用戶。雖然點贊這個功能點已經(jīng)很普遍了，但是千篇一律的生硬效果讓這么神圣的操作顯得很黯淡(扯淡了，不就是贊贊贊么...)，當然也有非常炫酷的，忍不住多點幾次贊的效果。比如twitter的點贊。就不碼字扯淡了，上圖上源碼

使用Path畫愛心
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();
取消時候愛心出現(xiàn)裂痕然后分成兩半分別向左右傾斜,使用** canvas**
rotate來旋轉(zhuǎn)達到傾斜效果
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
<com.ldoublem.thumbUplib.ThumbUpView
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();
如果覺得還可以，給顆小星星^^
