由于我还无法发布图片，请耐心等待。我在设备中查看db的存储数据时遇到问题。他们只是不和我打字的东西搭档。
例如，我在下面键入了这个：
fullname > jane doe
gender > female
age > 21
address > usa
contactnumber > 123456789
height(inches) > 53
weight(pounds) > 153
当我已经查看上述内容时，会发生这种情况：
fullname >
gender > 21
age >
address > 123456789
contactnumber > 53
height > 15
weight > 38.
这是我的ViewClient.java代码
public class DatabaseViewClient extends Activity {
private EditText fullname;
private EditText address_client;
private EditText age_client;
private EditText gender;
private EditText contactNum_client;
private EditText height_client;
private EditText weight_client;
private Button btnSaveCustomer;
int current_client_id;
String current_client_fullname;
String current_client_address;
String current_client_contactnum;
String current_client_height;
String current_client_weight;
String current_client_gender;
int current_client_age;
String current_client_bmi, current_client_status;
/**
* Called when the activity is first created.
*/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.addclient);

address_client.setText(current_client_address);
contactNum_client.setText(current_client_contactnum);
