【问题描述】:
我正在将数据存储到存储在 SD 卡中的 SQLiteDatabase,现在我必须将所有 SQLite 数据发送到服务器。 注意:我也为服务器数据库创建了相同的字段(类似于到 SQLite DB)例如:PersonName
在我用来检查的代码下面,我是否能够将数据存储到服务器(出于测试目的 - 我将用户接受的数据放入edittext)然后 发送到服务器,我成功。
String url = "http://localhost/ChurchData.php";
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("sPersonName", editPersonName.getText().toString()));
String resultServer = getHttpPost(url,params);
Log.d("Entire string::", " " + resultServer);
/*** Default Value ***/
strStatusID = "0";
strError = "";
JSONObject c;
try {
c = new JSONObject(resultServer);
strStatusID = c.getString("StatusID");
strError = c.getString("Message");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// prepare save data
if(strStatusID.equals("0"))
{
Toast.makeText(getApplicationContext(), "Already Exist !", Toast.LENGTH_LONG).show();
}
else
{
Toast.makeText(getApplicationContext(), "Data Uploaded Successfully!", Toast.LENGTH_SHORT).show();
}
return true;
}
private String getHttpPost(String url,
List<NameValuePair> params) {
StringBuilder str = new StringBuilder();
HttpClient client = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
try {
httpPost.setEntity(new UrlEncodedFormEntity(params));
HttpResponse response = client.execute(httpPost);
StatusLine statusLine = response.getStatusLine();
int statusCode = statusLine.getStatusCode();
if (statusCode == 200) { // Status OK
HttpEntity entity = response.getEntity();
InputStream content = entity.getContent();
BufferedReader reader = new BufferedReader(new InputStreamReader(content));
String line;
while ((line = reader.readLine()) != null) {
str.append(line);
}
} else {
Log.e("Log", "Failed to download result..");
}
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return str.toString();
}
所以我想知道,如何将 SQLite 数据库记录发送到服务器?我的数据库类如下所示:
public class myDBClasss extends SQLiteOpenHelper {
// Database Version
private static final int DATABASE_VERSION = 2;
// Database Name
private static final String DATABASE_NAME = "ChurchDB";
// Table Name
private static final String TABLE_MEMBER = "DataTable";
public myDBClasss(Context context) {
// to store data into SD Card
super(context, Environment.getExternalStorageDirectory()
+ File.separator + "ChurchData"
+ File.separator + DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db) {
// TODO Auto-generated method stub
// Create Table Name
db.execSQL("CREATE TABLE " + TABLE_MEMBER +
"(PersonName VARCHAR(100)," +
" PersonEmail VARCHAR(100)," +
" PersonTelephone VARCHAR(100)," +
" Newsletter VARCHAR(100));"); // checkbox
Log.d("CREATE TABLE","Create Table Successfully - classs");
}
// Insert Data
public long insertData(String strPersonName, String strPersonEmail, String strPersonTelephone, String strNewsletter) {
// TODO Auto-generated method stub
try {
SQLiteDatabase db;
db = this.getWritableDatabase(); // Write Data
ContentValues Val = new ContentValues();
Val.put("PersonName", strPersonName);
Val.put("PersonEmail", strPersonEmail);
Val.put("PersonTelephone", strPersonTelephone);
Val.put("Newsletter", strNewsletter); // checkbox
long rows = db.insert(TABLE_MEMBER, null, Val);
db.close();
return rows; // return rows inserted.
} catch (Exception e) {
return -1;
}
}
// Update Data
public long updateData(String strPersonName, String strPersonEmail, String strPersonTelephone, String strNewsletter){
// TODO Auto-generated method stub
try {
SQLiteDatabase db;
db = this.getWritableDatabase(); // Write Data
ContentValues Val = new ContentValues();
Val.put("PersonName", strPersonName);
Val.put("PersonEmail", strPersonEmail);
Val.put("PersonTelephone", strPersonTelephone);
Val.put("Newsletter", strNewsletter); // checkbox
long rows = db.update(TABLE_MEMBER, Val, "PersonName=?",
new String[] { String.valueOf(strPersonName) });
db.close();
return rows; // return rows updated.
} catch (Exception e) {
return -1;
}
}
// Fetch data
public String[] selectData(String strPersonName) {
// TODO Auto-generated method stub
try {
String arrData[] = null;
SQLiteDatabase db;
db = this.getReadableDatabase(); // Read Data
Cursor cursor = db.query(TABLE_MEMBER, new String[] { "*" },
"PersonName=?",
new String[] { String.valueOf(strPersonName) }, null, null, null, null);
if(cursor != null)
{
if (cursor.moveToFirst()) {
arrData = new String[cursor.getColumnCount()];
arrData[0] = cursor.getString(0);
arrData[1] = cursor.getString(1);
arrData[2] = cursor.getString(2);
arrData[3] = cursor.getString(3); // checkbox
}
}
cursor.close();
db.close();
return arrData;
} catch (Exception e) {
return null;
}
}
// Check for data(s) using PersonName field
public boolean exists(String strImageName) {
SQLiteDatabase db;
db = this.getReadableDatabase(); // Read Data
Cursor cursor = db.rawQuery("select 1 from DataTable where PersonName= ?",
new String[] { strImageName });
boolean exists = (cursor.getCount() > 0);
cursor.close();
return exists;
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
// TODO Auto-generated method stub
db.execSQL("DROP TABLE IF EXISTS " + TABLE_MEMBER);
// Re Create on method onCreate
onCreate(db);
}
}
