我想制作this,但我没有找到任何关键或其他任何方法。 (它在谷歌网站上被称为Morph)任何人都可以告诉我如何或发送一些参考文件吗?
编辑:
我想将布局设置为可见...你不知道我什么时候应该做shape.setVisibility(View.VISIBLE)?我尝试过但是直到第二次点击按钮才会启动动画。 (在第一次单击布局时,只设置为不显示动画)
片段布局:
<EditText
android:id="@+id/editText"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusable="true"
android:gravity="top"
android:padding="15dp" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:id="@+id/circle"
android:visibility="gone">
</LinearLayout>
<ImageButton
android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:background="@color/transparent"
android:contentDescription="share"
android:padding="15dp"
android:src="@drawable/ic_share_55x55px" />
片段:
ImageButton fab = (ImageButton) view.findViewById(R.id.share);
fab.setOnClickListener(new View.OnClickListener() {
@TargetApi(Build.VERSION_CODES.LOLLIPOP)
@Override
public void onClick(View view) {
LinearLayout shape = (LinearLayout) getActivity().findViewById(R.id.circle);
// Create a reveal {@link Animator} that starts clipping the view from
// the top left corner until the whole view is covered.
Animator animator = ViewAnimationUtils.createCircularReveal(
shape,
shape.getWidth() - 130,
shape.getHeight()- 130,
0,
(float) Math.hypot(shape.getWidth(), shape.getHeight()));
// Set a natural ease-in/ease-out interpolator.
animator.setInterpolator(new AccelerateDecelerateInterpolator());
animator.setDuration(400);
// Finally start the animation
animator.start();
}
});

您需要为视图设置动画(在此示例中为LinearLayout)。将createCircularReveal的x和y值设置为fab按钮。
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
LinearLayout shape = (LinearLayout) rootView.findViewById(R.id.circle);
// Create a reveal {@link Animator} that starts clipping the view from
// the top left corner until the whole view is covered.
Animator animator = ViewAnimationUtils.createCircularReveal(
shape,
0,
0,
0,
(float) Math.hypot(shape.getWidth(), shape.getHeight()));
// Set a natural ease-in/ease-out interpolator.
animator.setInterpolator(new AccelerateDecelerateInterpolator());
// Finally start the animation
animator.start();
}
});
这是有关createCircleReveal
的信息createCircularReveal(View view,
int centerX, int centerY, float startRadius, float endRadius);

不是将视图设置为GONE,而是将其设置为INVISIBLE。同时使视图setEnabled(false)以防止它被触摸等
LinearLayout shape;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View view = inflater.inflate(R.layout.reveal_effect_basic, container, false);
shape = (LinearLayout) view.findViewById(R.id.circle);
shape.setVisibility(View.INVISIBLE);
shape.setEnabled(false);
ImageButton fab = (ImageButton) view.findViewById(R.id.share);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Animator animator = ViewAnimationUtils.createCircularReveal(
shape,
shape.getWidth() - 130,
shape.getHeight() - 130,
0,
(float) Math.hypot(shape.getWidth(), shape.getHeight()));
shape.setVisibility(View.VISIBLE);
animator.setInterpolator(new AccelerateDecelerateInterpolator());
if (shape.getVisibility() == View.VISIBLE) {
animator.setDuration(400);
animator.start();
shape.setEnabled(true);
}
}
});
