Android搜索列表视图，如拨号盘搜索（搜索名称和号码）

Question

我使用网格视图创建了一个拨号盘，我在列表视图中显示了我的通话记录，我启用了搜索功能，用用户输入的号码（来自gridview）调用日志。现在我如何用联系人姓名搜索我的通话记录。假设当用户输入7时，它显示包含7号码的呼叫记录，其未显示包含联系人姓名中的字母p，q，r，s的呼叫记录。我必须同时过滤。

DialerHomeActivity.java

callListAdapter=new CustomAdapter(DialerHomeActivity.this, R.layout.list_row, Common.calloglist);

   /**
     * Enabling Search Filter
     * */
    // Capture Text in EditText
    phone_num_edt.addTextChangedListener(new TextWatcher() {

        @Override
        public void afterTextChanged(Editable arg0) {
            // TODO Auto-generated method stub
            String text = phone_num_edt.getText().toString().toLowerCase(Locale.getDefault());
            callListAdapter.filter(text);
        }

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

        @Override
        public void onTextChanged(CharSequence arg0, int arg1, int arg2,
                int arg3) {
            // TODO Auto-generated method stub
        }
    });

我认为您需要使用模式匹配算法。
