本人大四学生，做一个Android app作为毕业设计，边学边做，不知道哪里出了问题
在一次调试后，整个app在xml设置的颜色，会在app启动一段时间后突然变成透明的
java代码设置的颜色和动态生成的控件颜色没有受到影响
我的手机是vivo，android8.1.0
-----------------------------补充--------------------------------------
这个问题时出现在我向主界面的一个fragment添加了一个横向的RecyclerView后出现的，如果去掉这个RecyclerView就不会有问题
这个RecyclerView是装填的cardview
有大神知道这可能是什么原因导致的吗，救救孩子吧= =

控件绑定代码
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_main, container, false);
loadingPage = view.findViewById(R.id.loading_page);
cardRecyclerView = view.findViewById(R.id.card_recyclerview);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
loadingPage.removeAllViews();
loadingPage.setVisibility(View.GONE);
}
}, 3000);
getServerData(10);
colorLine = view.findViewById(R.id.color_line);
getColor = view.findViewById(R.id.get_color);
getColor.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Toast toast = Toast.makeText(getActivity(),String.valueOf(((ColorDrawable)colorLine.getBackground().mutate()).getColor()),Toast.LENGTH_SHORT);
toast.show();
}
});
mBanner = view.findViewById(R.id.banner);
Btn_User = view.findViewById(R.id.main_userBtn);
Btn_User.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent = new Intent(getActivity(), UserActivity.class);
startActivity(intent);
}
});
searchBox = view.findViewById(R.id.btn_search);
//为搜索框添加点击事件
searchBox.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent = new Intent(getActivity(), SearchActivity.class);
startActivity(intent);
}
});
FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, ScreenUtil.getScreenWidth(this.getContext()) / 2);
mBanner.setLayoutParams(layoutParams);
//修改切换动画
//mBanner.setPageTransformer(Transformer.Default);
initBanner(mBanner);
initLocalImage();
return view;
}
RecyclerView 数据装填代码
public void initCardRecyclerViewData(List<SimpleGame> GameList){
//创建布局管理
LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
layoutManager.setOrientation(LinearLayoutManager.HORIZONTAL);
cardRecyclerView.setLayoutManager(layoutManager);
mAdapter = new GameCardAdapter(R.layout.item_game_card, GameList);
//设置重复执行动画
mAdapter.isFirstOnly(true);
//设置分割线
mAdapter.setOnItemChildClickListener(this);
mAdapter.setOnItemClickListener(this);
cardRecyclerView.setAdapter(mAdapter);
}
适配器用的是CymChad的BaseRecyclerViewAdapterHelper
