我有一个活动，其中有一个用户列表，在回收站视图中显示。另外，我有一个带有searchview小部件的菜单。这是一张图片：
正如你在图片中看到的那样，我也有一个泡泡背景。这些气泡是动画的一部分，它们正在屏幕上移动。
现在，每当我按下搜索按钮时，动画就会停止，我所做的一切（除了完成活动之外）都会继续动画。
此外，这个问题只发生在我使用回收站视图时，我知道因为事先我有一个listview并且它工作得很好，但后来我决定改为适配器视图。
以下是一些代码段：
活动：
public class FollowingActivity extends AppCompatActivity {
private DrawerLayout mDrawerLayout;
ArrayList<String> member_names = new ArrayList<>();
ArrayList<String> users_uid = new ArrayList<>();
ValueEventListener uidListener;
ValueEventListener namesListener;
ArrayList<RowItem> rowItems = new ArrayList<>();
RecyclerView recyclerView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_friends_search);
Toolbar toolbar = findViewById(R.id.toolbar_add_friends);
setSupportActionBar(toolbar);
ActionBar actionbar = getSupportActionBar();
if(actionbar != null) {
actionbar.setDisplayHomeAsUpEnabled(true);
actionbar.setHomeAsUpIndicator(R.drawable.ic_menu);
}
setUpRecyclerView();
mDrawerLayout = findViewById(R.id.drawer_layout);
final DatabaseReference accountRef = FirebaseDatabase.getInstance().getReference().child("users");
final ImageView drawerAccountImageView = findViewById(R.id.drawer_image);
drawerAccountImageView.setImageResource(R.drawable.user);
final DatabaseReference friendsRef = FirebaseDatabase.getInstance().getReference().child("users").child(FirebaseAuth.getInstance().getCurrentUser().getUid()).child("Following");
uidListener = new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
users_uid = new ArrayList<>();
member_names = new ArrayList<>();
for (DataSnapshot snapshot : dataSnapshot.getChildren()){
if(!users_uid.contains(snapshot.getKey()))
users_uid.add(snapshot.getKey());
friendsRef.removeEventListener(this);
}
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
};
namesListener = new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
TextView nameView = mDrawerLayout.findViewById(R.id.drawer_name);
for (DataSnapshot snapshot : dataSnapshot.getChildren()) {
User user = snapshot.getValue(User.class);
/*check if the user wasn't added before*/
if ((user != null) && user.email.equals(FirebaseAuth.getInstance().getCurrentUser().getEmail())) {
String fullName = user.firstName + " " + user.lastName;
nameView.setText(fullName);
}
String fullName;
if(user != null) {
fullName = user.firstName + " " + user.lastName;
for(int i=0; i<users_uid.size(); i++){
for(int j=i+1; j<users_uid.size(); j++){
if(users_uid.get(i).equals(users_uid.get(j)))
users_uid.remove(j);
}
}
for (int i = 0; i < users_uid.size(); i++) {
if (users_uid.get(i).equals(snapshot.getKey())) {
member_names.add(fullName);
}
}
}
}
rowItems = new ArrayList<>();
for (int i = 0; i < users_uid.size(); i++) {
RowItem item = new RowItem(users_uid.get(i), member_names.get(i));
rowItems.add(item);
}
RelativeLayout mRelativeLayout = findViewById(R.id.zero_following_text);
if(users_uid.size() == 0){
mRelativeLayout.setVisibility(View.VISIBLE);
}
else{
mRelativeLayout.setVisibility(View.GONE);
}
FollowingCustomAdapter adapter = new FollowingCustomAdapter(FollowingActivity.this, rowItems);
recyclerView.setAdapter(adapter);
accountRef.removeEventListener(this);
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
};
friendsRef.addValueEventListener(uidListener);
accountRef.addValueEventListener(namesListener);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
mDrawerLayout.openDrawer(GravityCompat.START);
return true;
}
return super.onOptionsItemSelected(item);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.options_menu, menu);
SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
final SearchView searchView = (SearchView) menu.findItem(R.id.action_search).getActionView();
searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(true);
HelperMethods.changeSearchViewTextColor(searchView);
return true;
}
@Override
protected void onRestart() {
final DatabaseReference accountRef = FirebaseDatabase.getInstance().getReference().child("users");
final DatabaseReference friendsRef = FirebaseDatabase.getInstance().getReference().child("users").child(FirebaseAuth.getInstance().getCurrentUser().getUid()).child("Following");
friendsRef.addValueEventListener(uidListener);
accountRef.addValueEventListener(namesListener);
NavigationView navigationView = findViewById(R.id.nav_view);
navigationView.getMenu().findItem(R.id.nav_search_for_friends).setChecked(true);
super.onRestart();
}
private void setUpRecyclerView() {
recyclerView = findViewById(R.id.following_recycler_view);
recyclerView.setHasFixedSize(true);
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(linearLayoutManager);
}
}
options_menu.xml：
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:title="@string/search_title"
android:id="@+id/action_search"
android:icon="@drawable/ic_search_final"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="ifRoom|collapseActionView" />
</menu>
有人可以帮助我让动画继续吗？
编辑：当我隐藏循环视图时，它可以正常工作。我不知道问题是什么
