- 创建布局文件:在底部工作表布局文件中添加一个RecyclerView或ListView。
- 在Activity/Fragment中,设置底部工作表的弹跳动画效果:
BottomSheetDialog bottomSheetDialog = new BottomSheetDialog(this);
RecyclerView recyclerView = findViewById(R.id.recycler_view);
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(linearLayoutManager);
MyAdapter myAdapter = new MyAdapter(dataList);
recyclerView.setAdapter(myAdapter);
bottomSheetDialog.setContentView(recyclerView);
try {
Field behaviorField = bottomSheetDialog.getClass().getDeclaredField("behavior");
if (behaviorField != null) {
behaviorField.setAccessible(true);
Object behavior = behaviorField.get(bottomSheetDialog);
if (behavior instanceof BottomSheetBehavior) {
BottomSheetBehavior bottomSheetBehavior = (BottomSheetBehavior) behavior;
bottomSheetBehavior.setBottomSheetCallback(new BottomSheetCallback() {
@Override
public void onStateChanged(@NonNull View bottomSheet, int newState) {
if (newState == BottomSheetBehavior.STATE_EXPANDED) {
animateIn(mainLayout);
} else if (newState == BottomSheetBehavior.STATE_HIDDEN) {
animateOut(mainLayout);
bottomSheetDialog.dismiss();
}
}
@Override
public void onSlide(@NonNull View bottomSheet, float slideOffset) {
// Set the translationX/Y of mainLayout here to achieve the bounce animation effect
}
});
}
}
} catch (NoSuchFieldException | IllegalAccessException e) {
e.printStackTrace();
}
- 为了实现弹跳动画效果,通过修改布局中主要布局的translationX/Y值来使其在弹跳动画的过程中改变其位置。具体可以在onSlide回调方法中实现:
private void animateIn(View view) {
Animation animation = new TranslateAnimation(0, 0, view.getHeight(), 0);
animation.setDuration(300);
view.startAnimation(animation);
}
private void animateOut(View view) {
Animation animation = new TranslateAnimation(0, 0, 0
