Question

我在片段中有回收视图。当在循环器视图中单击项目时，我调用方法替换片段。我将ripple.xml自定义为后台项目recyclerview，但在替换时不显示动画。这是我的代码： custom_bg.xml for api＆lt; 20

＆＃13;

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <shape>
            <solid android:color="@android:color/holo_blue_light"></solid>
        </shape>
    </item>
    <item >
        <shape>
            <solid android:color="@android:color/white"></solid>
        </shape>
    </item>
</selector>

＆＃13;

＆＃13; custom_bg.xml涟漪效应

＆＃13;

<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="?android:attr/colorControlHighlight">
    <item
        android:id="@android:id/mask"
        android:drawable="@android:color/white">
    </item>
</ripple>

＆＃13;

＆＃13; item.xml

＆＃13;

        style="@style/CommonLine"
        android:layout_alignParentBottom="true" />
</RelativeLayout>

＆＃13;

＆＃13; 在myadapter.class中，我调用了事件

＆＃13;

 private class ContentViewHolder extends RecyclerView.ViewHolder {
       
        private final RelativeLayout mRoot;

        public ContentViewHolder(View itemView) {
            super(itemView);
            mRoot = (RelativeLayout) itemView.findViewById(R.id.mRoot);
            mRoot.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    mListener.onItemClick(getLayoutPosition());
                }
            });
        }
    }

＆＃13;

并在myfragment.class中调用

＆＃13;

 mAdapter = new GameListAdapter(mContext, new GameListAdapter.OnGameAdapterListener() {
            @Override
            public void onItemClick(int position) {
                if (position < mObjects.size()) {
                    Object object = mObjects.get(position);
                    if (object instanceof Schedule) {
                        if (getParentFragment() instanceof BaseContainerFragment) {
                            if (!isItemClicked) {
                                isItemClicked = true;
                                ((BaseContainerFragment) getParentFragment()).replaceFragment(GameDetailFragment_.builder().mSchedule((Schedule) object).build(), true);
                            }
                        }
                    }
                }
            }
        });

＆＃13;

public void replaceFragment(Fragment fragment, boolean addToBackStack) {
        FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
transaction.setCustomAnimations(R.anim.slide_in_right, 0);
        if (addToBackStack) {
            transaction.addToBackStack(null);
        }
        transaction.replace(R.id.mFrameContainer, fragment);
        transaction.commitAllowingStateLoss();
    }

＆＃13;

＆＃13; 我试过延迟它显示动画，但它非常滞后。我该怎么办呢？非常感谢你！

请使用此

android:foreground="?attr/selectableItemBackground"

或者

android:foreground="?android:attr/selectableItemBackground"

或者

android:background="?attr/selectableItemBackground"

或者

android:background="?android:attr/selectableItemBackground"

在recyclerview的item.xml的父布局中，这将自动生成涟漪效应。
