inputSearch  = (EditText)   rootview.findViewById(R.id.inputSearch);
listView.setOnItemClickListener(this);
getJSON();
inputSearch.addTextChangedListener(new TextWatcher() {
                @Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
UserFragment.this.adapter.getFilter().filter(cs);
}
                @Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
                                              int arg3) {
                }
                @Override
public void afterTextChanged(Editable arg0) {
                }
            });
return rootview;
        }
private void Display(){
JSONObject jsonObject = null;
ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String, String>>();
try {
jsonObject = new JSONObject(JSON_STRING);
JSONArray result = jsonObject.getJSONArray(TAG_JSON_ARRAY);
 for(int i = 0; i<result.length(); i++){
JSONObject jo = result.getJSONObject(i);
String name = jo.getString("Nom");
String email = jo.getString("Email");
String login = jo.getString("Login");
HashMap<String,String> users= new HashMap<>();
users.put("name",name);
users.put("email",email);
users.put("login",login);
list.add(users);
                }
            } catch (JSONException e) {
                e.printStackTrace();
            }
            ListAdapter adapter = new SimpleAdapter(
                    getActivity(), list, R.layout.list_row,
                    new String[]{"name","email"},
                    new int[]{R.id.nom, R.id.email2});
            listView.setAdapter(adapter);
        }

您可以使用

android:drawableEnd="@drawable/view"

在您的编辑文字中添加图标。

您可以通过在edittext上添加TextView.OnEditorActionListener来搜索listview。例： myEditText.setOnEditorActionListener（new OnEditorActionListener（）{
@覆盖 public boolean onEditorAction（TextView v，int actionId，KeyEvent event）{ //做一些事情 } }）;
