小编jen*_*fer的帖子

我的代码是

ContentValues values; 
values = new ContentValues();
        values.put(SQLHelper.EMPLOYEE_LPN, jsObj.getString("lpn"));
db.update(SQLHelper.EMPLOYEE_TABLE, values,
                "EMPLOYEE_LPN ='" + jsObj.getString("lpn") + "'",
                null);

Log Cat中显示警告

怎么解决？

我有一个JSON结构,如下所示.如何以编程方式创建此Array结构？

JSON结构:

{ 
"Employee": 
    [ 
      { 
        "EmP325235": 
          { 
             "Name":"Rekha_S", 
             "firstName":"Rekha", 
             "phoneWork":"788908909", 
             "lastName":"S", 
             "namePrefix":"Miss", 
             "phoneMobile":"3347687878", 
             "phoneHome":"5768900909", 
             "Email":"" 
          }, 
        "Em252555": 
          { 
             "Name":"Roopa_N", 
             "firstName":"Roopa", 
             "phoneWork":"0471245367", 
             "lastName":"N", 
             "namePrefix":"", 
             "phoneMobile":"", 
             "phoneHome":"", 
             "Email":"" 
      } 
      } 
    ], 
"User_Details": 
   { 
       "USER_ID":"7890", 
        "Number":"8585858585", 
        "Password":"Passwordsgs" 
   } 
}

我正在尝试加载手机通讯录并尝试按升序显示联系人姓名.我的代码如下:

    Cursor cursor = getContentResolver().query(
    ContactsContract.Contacts.CONTENT_URI, null,
    ContactsContract.Contacts.HAS_PHONE_NUMBER + " = 1", null,
    ContactsContract.Contacts.DISPLAY_NAME + " ASC");

我得到了所需的输出.但是问题出在那里,用小写字母盯着的名字显示为最后一个.首先,大写字母被排序,只有在显示用小写字母盯着的联系人姓名之后.PLS帮助

输出是:

Alfin A
Bipin B
Calvin C
Jobin
Shine
anurag U
shine H

我的代码是:

EditText edt

    edt.addTextChangedListener(new TextWatcher() {

            @Override
            public void afterTextChanged(Editable arg0) {

            final String number = edt.getText().toString();

            int count = arg0.length();
            edt.setSelection(count);

        }

                    }

            @Override
            public void beforeTextChanged(CharSequence s, int start, int count,
                int after) {
            // TODO Auto-generated method stub

            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before,
                int count) {

            final String number = edt.getText().toString();

                    }

我也有一个拨号盘.当我点击拨号盘中的特定号码时,我需要将该号码添加到当前光标位置.此外,当我按删除时,我需要删除当前光标位置的数字.
