前言
本文主要給大家介紹了關于Android如何實現移動小球和CircularReveal頁面切換動畫的相關內容，分享出來供大家參考學習，下面話不多說了，來一起看看詳細的介紹吧。
效果圖如下
是在fragment中跳轉activity實現的效果，fragment跳fragment，activity跳activity類似~~
實現過程
重寫Fab的onTouchListener()
floatingActionButton.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View view, MotionEvent ev) { switch (ev.getAction()) { case MotionEvent.ACTION_DOWN: downX = ev.getX(); downY = ev.getY(); isClick = true; break; case MotionEvent.ACTION_MOVE: isClick = false; moveX = ev.getX(); moveY = ev.getY(); int offsetX = (int) (moveX - downX); int offsetY = (int) (moveY - downY); //這里使用了setTranslation來移動view。。。嘗試過layout。不知道為什么fragment切換回來的時候會恢復原位 floatingActionButton.setTranslationX(floatingActionButton.getTranslationX() + offsetX); floatingActionButton.setTranslationY(floatingActionButton.getTranslationY() + offsetY); break; case MotionEvent.ACTION_UP: //用來觸發點擊事件 if (isClick) { startAct(); return false; } //用來判斷移動邊界 if (floatingActionButton.getX() < 0) { floatingActionButton.setX(0); } if (floatingActionButton.getX() + floatingActionButton.getWidth() > ScreenUtil.getScreenWidth(getContext())) { floatingActionButton.setX(ScreenUtil.getScreenWidth(getContext()) - floatingActionButton.getWidth()); } if (floatingActionButton.getY() < titleHeight) { floatingActionButton.setY(0); } if (floatingActionButton.getY() + floatingActionButton.getHeight() + titleHeight > getActivity().findViewById(R.id.activity_main_mainLl).getHeight() - getActivity().findViewById(R.id.fc_rg).getHeight()) { floatingActionButton.setY(getBottomY()); } break; } return true; } private void startAct() { //跳轉Activity,傳遞動畫參數 Intent intent = new Intent(getActivity(), CheckWorkActivity.class); intent.putExtra("x", (int) floatingActionButton.getX() + floatingActionButton.getWidth() / 2); intent.putExtra("y", (int) floatingActionButton.getY() + floatingActionButton.getHeight() / 2); intent.putExtra("start_radius", floatingActionButton.getWidth() / 2); intent.putExtra("end_radius", DialogFragment.this.view.getHeight()); startActivity(intent); } });在下一個頁面中實現CircleRevel動畫
onCrete中調用
private void initAnimation() { //ll為根布局 final LinearLayout linearLayout = (LinearLayout) findViewById(R.id.ll); linearLayout.post(new Runnable() { @Override public void run() { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { Animator animator = ViewAnimationUtils.createCircularReveal( linearLayout,// 操作的視圖 getIntent().getIntExtra("x", 0), // 動畫的中心點X getIntent().getIntExtra("y", 0) + findViewById(R.id.title).getHeight(), // 動畫的中心點Y getIntent().getIntExtra("start_radius", 0), // 動畫半徑 getIntent().getIntExtra("end_radius", 0) // 動畫結束半徑 ); animator.setInterpolator(new AccelerateInterpolator()); animator.setDuration(500); animator.start(); } } }); }點擊后退或者觸發onBackPressed時候調用
private void endAnim() { final LinearLayout linearLayout = (LinearLayout) findViewById(R.id.ll); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { Animator animator = ViewAnimationUtils.createCircularReveal( linearLayout,// 操作的視圖 getIntent().getIntExtra("x", 0), getIntent().getIntExtra("y", 0) + findViewById(R.id.title).getHeight(), getIntent().getIntExtra("end_radius", 0), getIntent().getIntExtra("start_radius", 0) ); animator.setInterpolator(new AccelerateInterpolator()); animator.setDuration(500); animator.addListener(new AnimatorListenerAdapter() { @Override public void onAnimationEnd(Animator animation) { super.onAnimationEnd(animation); finish(); } }); animator.start(); } }還有一個重要的地方是修改兩個activity的theme
<style name="AppThemeCircleRevel" parent="Theme.AppCompat.Light.NoActionBar"> <!-- Customize your theme here. --> <item name="colorPrimary">@color/colorPrimary</item> <item name="colorPrimaryDark">@color/colorPrimaryDark</item> <item name="colorAccent">@color/blue</item> <item name="android/212126.html">android:windowAnimationStyle">@null</item> <item name="android:windowBackground">@android:color/transparent</item> <item name="android:windowIsTranslucent">true</item> <item name="android:colorBackgroundCacheHint">@null</item> </style>
