SearchView在具有自定义适配器的ListView中

伙计们我需要一些帮助。我一直在尝试在我的项目中实现一个SearchView。但是我的项目包含一个列表视图,附带一个自定义适配器..我搜索了很多站点,但都有使用arrayadapter实现的示例。 。假设我有一个Employee类,它包含名称和年龄字段。如何使用他们的名称来过滤员工..

public class MainActivity extends Activity implements SearchView.OnQueryTextListener { SearchView mSearchView; ListView mListView; //String mStrings[]= {"abc","def","efg","ghi","ijk","apple","agxhsdgc","abbbcc"}; ArrayList emp_list=null; EmployeeAdapter emp_adapter=null; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mSearchView=(SearchView) findViewById(R.id.searchView1); mListView=(ListView) findViewById(R.id.listView1); emp_list=new ArrayList(); emp_list.add(new Employee("ABC", 24)); emp_list.add(new Employee("ACB", 24)); emp_list.add(new Employee("BVF", 28)); emp_list.add(new Employee("BRT", 28)); emp_list.add(new Employee("ANM", 23)); emp_adapter=new EmployeeAdapter(MainActivity.this, emp_list); mListView.setAdapter(emp_adapter); // mListView.setAdapter(new ArrayAdapter(this, // android.R.layout.simple_list_item_1, // mStrings)); mListView.setTextFilterEnabled(true); setupSearchView(); } private void setupSearchView() { mSearchView.setIconifiedByDefault(false); mSearchView.setOnQueryTextListener(this); mSearchView.setSubmitButtonEnabled(true); mSearchView.setQueryHint("Search Here"); } @Override public boolean onQueryTextChange(String newText) { if (TextUtils.isEmpty(newText.toString())) { mListView.clearTextFilter(); } else { mListView.setFilterText(newText.toString()); } return true; } @Override public boolean onQueryTextSubmit(String query) { return false; } } 

这是我的扩展BaseAdapter的适配器类..

 public class EmployeeAdapter extends BaseAdapter { Context ctx; ArrayList emp_list; LayoutInflater linf=null; EmployeeHolder holder=null; public EmployeeAdapter(Context ctx, ArrayList emp_list) { super(); this.ctx = ctx; this.emp_list = emp_list; linf=(LayoutInflater) ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE); } public class EmployeeHolder { TextView name; TextView age; } @Override public int getCount() { // TODO Auto-generated method stub return emp_list.size(); } @Override public Object getItem(int position) { // TODO Auto-generated method stub return emp_list.get(position); } @Override public long getItemId(int position) { // TODO Auto-generated method stub return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { // TODO Auto-generated method stub if(convertView==null) { convertView=linf.inflate(R.layout.row, parent, false); holder=new EmployeeHolder(); holder.name=(TextView) convertView.findViewById(R.id.name); holder.age=(TextView) convertView.findViewById(R.id.age); convertView.setTag(holder); } else { holder=(EmployeeHolder) convertView.getTag(); } Employee e=(Employee) getItem(position); holder.name.setText(e.getName()); holder.age.setText(String.valueOf(e.getAge())); return convertView; } } 

提前致谢..

activity_main.xml中

     

row.xml

MainActivity.java

 public class MainActivity extends Activity implements SearchView.OnQueryTextListener { private SearchView mSearchView; private ListView mListView; private ArrayList employeeArrayList; private EmployeeAdapter employeeAdapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mSearchView=(SearchView) findViewById(R.id.searchView1); mListView=(ListView) findViewById(R.id.listView1); employeeArrayList=new ArrayList(); employeeArrayList.add(new Employee("ABC", 24)); employeeArrayList.add(new Employee("ACB", 24)); employeeArrayList.add(new Employee("BVF", 28)); employeeArrayList.add(new Employee("BRT", 28)); employeeArrayList.add(new Employee("ANM", 23)); employeeAdapter=new EmployeeAdapter(MainActivity.this, employeeArrayList); mListView.setAdapter(employeeAdapter); mListView.setTextFilterEnabled(true); setupSearchView(); } private void setupSearchView() { mSearchView.setIconifiedByDefault(false); mSearchView.setOnQueryTextListener(this); mSearchView.setSubmitButtonEnabled(true); mSearchView.setQueryHint("Search Here"); } @Override public boolean onQueryTextChange(String newText) { if (TextUtils.isEmpty(newText)) { mListView.clearTextFilter(); } else { mListView.setFilterText(newText); } return true; } @Override public boolean onQueryTextSubmit(String query) { return false; } } 

EmployeeAdapter.java

 public class EmployeeAdapter extends BaseAdapter implements Filterable { public Context context; public ArrayList employeeArrayList; public ArrayList orig; public EmployeeAdapter(Context context, ArrayList employeeArrayList) { super(); this.context = context; this.employeeArrayList = employeeArrayList; } public class EmployeeHolder { TextView name; TextView age; } public Filter getFilter() { return new Filter() { @Override protected FilterResults performFiltering(CharSequence constraint) { final FilterResults oReturn = new FilterResults(); final ArrayList results = new ArrayList(); if (orig == null) orig = employeeArrayList; if (constraint != null) { if (orig != null && orig.size() > 0) { for (final Employee g : orig) { if (g.getName().toLowerCase() .contains(constraint.toString())) results.add(g); } } oReturn.values = results; } return oReturn; } @SuppressWarnings("unchecked") @Override protected void publishResults(CharSequence constraint, FilterResults results) { employeeArrayList = (ArrayList) results.values; notifyDataSetChanged(); } }; } public void notifyDataSetChanged() { super.notifyDataSetChanged(); } @Override public int getCount() { return employeeArrayList.size(); } @Override public Object getItem(int position) { return employeeArrayList.get(position); } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { EmployeeHolder holder; if(convertView==null) { convertView=LayoutInflater.from(context).inflate(R.layout.row, parent, false); holder=new EmployeeHolder(); holder.name=(TextView) convertView.findViewById(R.id.txtName); holder.age=(TextView) convertView.findViewById(R.id.txtAge); convertView.setTag(holder); } else { holder=(EmployeeHolder) convertView.getTag(); } holder.name.setText(employeeArrayList.get(position).getName()); holder.age.setText(String.valueOf(employeeArrayList.get(position).getAge())); return convertView; } } 

Employee.java

 public class Employee { private String name; private int age; public Employee(String name,int age){ this.name = name; this.age = age; } public String getName(){ return name; } public int getAge(){ return age; } } 

答案很好,但仍有一些问题(onclick错误的位置,serchview文本叠加),如评论部分所述,所以你也可以通过以下方式做到这一点

参考更多信息: searchview listview android

我已经测试了它,到目前为止没有find任何问题,如果您发现任何问题,请在评论部分提及。

模型类:MovieNames.java

 public class MovieNames { private String movieName; public MovieNames(String movieName) { this.movieName = movieName; } public String getAnimalName() { return this.movieName; } }

快乐的编码

菜单:menu_doctor_list.xml

 < ?xml version="1.0" encoding="utf-8"?>    

活动:

 public class ListActivity extends AppActivity implements SearchView.OnQueryTextListener { public boolean onCreateOptionsMenu(Menu menu) { MenuInflater menuInflater = getMenuInflater(); menuInflater.inflate(R.menu.menu_doctor_list, menu); MenuItem searchItem = menu.findItem(R.id.action_search); SearchView searchView = (SearchView) searchItem.getActionView(); searchView.setQueryHint("Search Doctor by Name or Specialization"); searchView.setOnQueryTextListener(this); searchView.setOnCloseListener(this); searchView.setIconified(false); return true; } @Override public boolean onQueryTextSubmit(String query) { System.out.println("query = " + query); doctorListAdapter.getFilter().filter(query); return true; } @Override public boolean onQueryTextChange(String newText) { System.out.println("query = " + newText); doctorListAdapter.getFilter().filter(newText); return true; } } 

适配器:

 public class ListAdapter extends RecyclerView.Adapter implements Filterable { private List mOriginalValues; // Original Values private List mDisplayedValues; // Values to be displayed use this in onBindViewHolder() public DoctorListAdapter(Context context, List appointmentList) { this.mOriginalValues = appointmentList; this.mDisplayedValues = appointmentList; } @Override public Filter getFilter() { Filter filter = new Filter() { @SuppressWarnings("unchecked") @Override protected void publishResults(CharSequence constraint, FilterResults results) { mDisplayedValues = (ArrayList) results.values; // has the filtered values notifyDataSetChanged(); // notifies the data with new filtered values } @Override protected FilterResults performFiltering(CharSequence constraint) { FilterResults results = new FilterResults(); // Holds the results of a filtering operation in values ArrayList FilteredArrList = new ArrayList(); if (mOriginalValues == null) { mOriginalValues = new ArrayList(mDisplayedValues); // saves the original data in mOriginalValues } /******** * * If constraint(CharSequence that is received) is null returns the mOriginalValues(Original) values * else does the Filtering and returns FilteredArrList(Filtered) * ********/ if (constraint == null || constraint.length() == 0) { // set the Original result to return results.count = mOriginalValues.size(); results.values = mOriginalValues; } else { constraint = constraint.toString().toLowerCase(); for (int i = 0; i < mOriginalValues.size(); i++) { String data = mOriginalValues.get(i).getFirstname() + " " + mOriginalValues.get(i).getLastname(); if (data.toLowerCase().startsWith(constraint.toString())) { FilteredArrList.add(mOriginalValues.get(i)); } } // set the Filtered result to return results.count = FilteredArrList.size(); results.values = FilteredArrList; } return results; } }; return filter; } }
