android - 使用 EditText Android 过滤 Json Listview

Question

试图用 edittext 过滤我的 ListView ，每次我输入一些文本时 ListView 变成空白，谁能告诉我我做错了什么以及我该如何解决这个问题

search.addTextChangedListener(new TextWatcher (){
    public void afterTextChanged(Editable arg0) {
        // TODO Auto-generated method stub

    }

    public void beforeTextChanged(CharSequence arg0, int arg1,
    int arg2, int arg3) {
        // TODO Auto-generated method stub

    }

    public void onTextChanged(CharSequence cs, int arg1, int arg2,
    int arg3) {
        // TODO Auto-generated method stub



        String searchString = cs.toString();//wsSearch.getText().toString();
       /* if(searchString.length() != 2) {
            adapter2 = new Adapter(MainActivity.this, array);
            listView.setAdapter(adapter2);
            return;
        }*/
        for (int i = 0; i < array.size(); i++)
        {
            String currentString = array.get(i).getTitulo();
            if (searchString.equalsIgnoreCase(currentString))
            {
                mTemp.add(array.get(i));
            }
        }
        adapter2 = new Adapter(MainActivity.this, mTemp);
        listView.setAdapter(adapter2);

    }



});
}

试试这个:

    search.addTextChangedListener(new TextWatcher(){
        public void afterTextChanged(Editable arg0) {
            // TODO Auto-generated method stub
            String searchString = arg0.toString();//wsSearch.getText().toString();
   /* if(searchString.length() != 2) {
        adapter2 = new Adapter(MainActivity.this, array);
        listView.setAdapter(adapter2);
        return;
    }*/     
            mTemp.clear()
            for (int i = 0; i < array.size(); i++)
            {
                String currentString = array.get(i).getTitulo();
                if (currentString.contains(searchString))
                {
                    mTemp.add(array.get(i));
                }
            }
            adapter2 = new Adapter(MainActivity.this, mTemp);
            listView.setAdapter(adapter2);

        }

        public void beforeTextChanged(CharSequence arg0, int arg1,
                                      int arg2, int arg3) {
            // TODO Auto-generated method stub

        }

        public void onTextChanged(CharSequence cs, int arg1, int arg2,
                                  int arg3) {
            // TODO Auto-generated method stub
            //BAPTISMAL_SONG.this.adapter2.getFilter().filter(cs);




        }



    });
