我在我的应用程序中使用com.github.mancj:MaterialSearchBar:+
依赖项来搜索SQLite数据库中的数据。它确实基于我在数据库中的数据加载建议,但是当用户单击建议之一并通过单击键盘中的搜索图标确认建议时,什么都不会显示,则不会调用适配器来显示结果。以下是我的搜索活动
recyclerView = findViewById(R.id.hyme_list);
layoutManager = new LinearLayoutManager(this);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setHasFixedSize(true);
materialSearchBar = findViewById(R.id.searchBar);
database = new Database(this);
materialSearchBar.setHint("Search here");
materialSearchBar.setCardViewElevation(10);
loadSuggestList();
materialSearchBar.addTextChangeListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
@Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
List<String> sugest = new ArrayList<>();
for (String search: suggestList) {
if (search.toUpperCase().contains(materialSearchBar.getText().toUpperCase()))
sugest.add(search);
}
materialSearchBar.setLastSuggestions(sugest);
}
@Override
public void afterTextChanged(Editable editable) {
}
});
materialSearchBar.setOnSearchActionListener(new MaterialSearchBar.OnSearchActionListener() {
@Override
public void onSearchStateChanged(boolean enabled) {
if (!enabled){
searchAdapter = new SearchAdapter(getBaseContext(),database.getSongs());
recyclerView.setAdapter(searchAdapter);
}
}
@Override
public void onSearchConfirmed(CharSequence text) {
startSearch(text.toString());
}
@Override
public void onButtonClicked(int buttonCode) {
}
});
searchAdapter = new SearchAdapter(this,database.getSongs());
recyclerView.setAdapter(searchAdapter);
}
private void startSearch(String text) {
searchAdapter = new SearchAdapter(this,database.getSongByName(text));
recyclerView.setAdapter(searchAdapter);
}
private void loadSuggestList() {
suggestList = database.getTitle();
materialSearchBar.setLastSuggestions(suggestList);
}
