属性动画实现卫星菜单

这个动画效果挺好玩的

间隔可以自己设定—–可以自己封装相应方法

既然是最低层的东西,自然想做成什么样子就做成什么样子

直接上代码 一运行就都明白了

布局文件

好了运行程序

谁知道运行效果图怎么贴上来,麻烦给支个招,不胜感激

上篇博客,属性动画实现平移 view高度的动态获取

public class DropTest extends Activity {

private LinearLayout mHiddenView;
private float mDensity;
private int mHiddenViewMeasuredHeight;

int viewHeight;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.drop);
mHiddenView = (LinearLayout) findViewById(R.id.hidden_view);
// 获取像素密度
mDensity = getResources().getDisplayMetrics().density;
// 获取布局的高度

}

public void llClick(View view) {
if (mHiddenView.getVisibility() == View.GONE) {

//            viewHeight = mHiddenView.getHeight();
//              Log.e("lc---",viewHeight+"dp");
//            mHiddenViewMeasuredHeight = (int) (mDensity * viewHeight + 0.5);
// 打开动画
animateOpen(mHiddenView);
} else {
// 关闭动画
mHiddenView.getViewTreeObserver().addOnGlobalLayoutListener(
new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {

viewHeight = mHiddenView.getHeight();
Log.e("lc---",viewHeight+"dp");
mHiddenViewMeasuredHeight = (int) (mDensity * viewHeight + 0.5);
mHiddenView.getViewTreeObserver()
.removeGlobalOnLayoutListener(this);
}
});
animateClose(mHiddenView);
}
}

private void animateOpen(final View view) {
view.setVisibility(View.VISIBLE);
ValueAnimator animator = createDropAnimator(
view,
0,
mHiddenViewMeasuredHeight);
animator.start();
}

private void animateClose(final View view) {
int origHeight = view.getHeight();
ValueAnimator animator = createDropAnimator(view, origHeight, 0);
animator.addListener(new AnimatorListenerAdapter() {
public void onAnimationEnd(Animator animation) {
view.setVisibility(View.GONE);
// animateOpen(view);
//                animation.start();
}
});

animator.start();
}

private ValueAnimator createDropAnimator(
final View view, int start, int end) {
ValueAnimator animator = ValueAnimator.ofInt(start, end);
animator.addUpdateListener(
new ValueAnimator.AnimatorUpdateListener() {

@Override
public void onAnimationUpdate(ValueAnimator valueAnimator) {
int value = (Integer) valueAnimator.getAnimatedValue();
ViewGroup.LayoutParams layoutParams =
view.getLayoutParams();
layoutParams.height = value;
view.setLayoutParams(layoutParams);
}
});
return animator;
}
}
