上傳圖像到文件夾和圖像路徑到MS SQL Server數據庫的Android代碼

Question

我需要從android項目上傳圖像到服務器文件夾和URL到MS SQL數據庫表。

我有一些代碼來捕捉圖像或從圖庫中選擇，現在我需要上傳圖像到服務器文件夾及其URL表

Answer 1

下面的代碼登錄MS SQL，把它作爲一個參考在表格中，你想使用應該是你進入 即「DB」默認數據庫用戶數據庫更新URL應該是「取消」

public class MainActivity extends ActionBarActivity 
{ 
// Declaring layout button, edit texts 
Button login; 
EditText username,password; 
ProgressBar progressBar; 
// End Declaring layout button, edit texts 

// Declaring connection variables 
Connection con; 
String un,pass,db,ip; 
//End Declaring connectaaion variables 
protected void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    // Getting values from button, texts and progress bar 
    login = (Button) findViewById(R.id.button); 
    username = (EditText) findViewById(R.id.editText); 
    password = (EditText) findViewById(R.id.editText2); 
    //progressBar = (ProgressBar) findViewById(R.id.progressBar); 
    // End Getting values from button, texts and progress bar 

    // Declaring Server ip, username, database name and password 
    ip = "yourIP"; 
    db = "DatabaseName"; 
    un = "userName"; 
    pass = "password"; 
    // Declaring Server ip, username, database name and password 

    // Setting up the function when button login is clicked 
    login.setOnClickListener(new View.OnClickListener() 
    { 
     @Override 
     public void onClick(View v) 
     { 
      CheckLogin checkLogin = new CheckLogin();// this is the Asynctask, which is used to process in background to reduce load on app process 
      checkLogin.execute(username.getText().toString(),password.getText().toString()); 
     } 
    }); 
    //End Setting up the function when button login is clicked 
} 

public class CheckLogin extends AsyncTask<String,String,String> 
{ 
    String z = ""; 
    Boolean isSuccess = false; 

    @Override 
    protected void onPreExecute() 
    { 
     //progressBar.setVisibility(View.VISIBLE); 
    } 

    @Override 
    protected void onPostExecute(String r) 
    { 
     //progressBar.setVisibility(View.GONE); 
     Toast.makeText(MainActivity.this, r, Toast.LENGTH_SHORT).show(); 
     if(isSuccess) 
     { 
      Toast.makeText(MainActivity.this , "Login Successfull" , Toast.LENGTH_LONG).show(); 
      //finish(); 
      Intent intent = new Intent(MainActivity.this, HomePage.class); 

      startActivity(intent); 
      finish(); 
     } 
    } 
    @Override 
    protected String doInBackground(String... params) 
    { 
     String usernam = params[0]; 
     String passwordd = params[1]; 
     if(usernam.trim().equals("")|| passwordd.trim().equals("")) 
      z = "Please enter Username and Password"; 
     else 
     { 
      try 
      { 
       con = connectionclass(un, pass, db, ip);  // Connect to database 
       if (con == null) 
       { 
        z = "Check Your Internet Access!"; 
       } 
       else 
       { 
        // Change below query according to your own database. 
        //String query ="select * from dbo.AA_UserMaster where UserName= 'test' and Password = 'admin1*'"; 
        String query = "select UserId from [AA_UserMaster] where UserName= '" + usernam.toString() + "' and Password = '"+ passwordd.toString() +"' "; 
        Statement stmt = con.createStatement(); 
        ResultSet rs = stmt.executeQuery(query); 
        if(rs.next()) 
        { 
         z = "Login successful"; 
         isSuccess=true; 
         con.close(); 
        } 
        else 
        { 
         z = "Invalid Credentials!"; 
         isSuccess = false; 
        } 
       } 
      } 
      catch (Exception ex) 
      { 
       isSuccess = false; 
       z = ex.getMessage(); 
      } 
     } 
     return z; 
    } 
} 


@SuppressLint("NewApi") 
public Connection connectionclass(String user, String password, String database, String server) 
{ 
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); 
    StrictMode.setThreadPolicy(policy); 
    Connection connection = null; 
    String ConnectionURL = null; 
    try 
    { 
     Class.forName("net.sourceforge.jtds.jdbc.Driver"); 
     ConnectionURL = "jdbc:jtds:sqlserver://" + server + ";" + database + ";user=" + user+ ";password=" + password + ";"; 
     connection = DriverManager.getConnection(ConnectionURL); 
    } 
    catch (SQLException se) 
    { 
     Log.e("error here 1 : ", se.getMessage()); 
    } 
    catch (ClassNotFoundException e) 
    { 
     Log.e("error here 2 : ", e.getMessage()); 
    } 
    catch (Exception e) 
    { 
     Log.e("error here 3 : ", e.getMessage()); 
    } 
    return connection; 
} 

}

使用此功能的默認數據庫：

private void setImage(String path, CircleImageView img) { 

    options = new DisplayImageOptions.Builder() 
      .cacheInMemory(true) 
      .cacheOnDisk(true) 
      .considerExifParams(true) 
      .bitmapConfig(Bitmap.Config.RGB_565) 
      .showImageOnLoading(R.drawable.user) 
      .showImageForEmptyUri(R.drawable.user) 
      .showImageOnFail(R.drawable.user) 
      .build(); 

    ImageLoader.getInstance().displayImage(path, img, options, new SimpleImageLoadingListener() { 
     @Override 
     public void onLoadingStarted(String imageUri, View view) { 
      super.onLoadingStarted(imageUri, view); 
     } 

     @Override 
     public void onLoadingFailed(String imageUri, View view, FailReason failReason) { 
      super.onLoadingFailed(imageUri, view, failReason); 
     } 

     @Override 
     public void onLoadingCancelled(String imageUri, View view) { 
      super.onLoadingCancelled(imageUri, view); 
     } 

     @Override 
     public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) { 
      super.onLoadingComplete(imageUri, view, loadedImage); 
     } 
    }, new ImageLoadingProgressListener() { 
     @Override 
     public void onProgressUpdate(String s, View view, int i, int i1) { 
     } 
    });

我有這個問題前面，實際上做的最好的事情就是使用第三方庫，我建議Retrofti，你可以找到一個tutlorial使用REtorfit通過這個link
