Hoy獲取imageview圖像的完整大小？

Question

我已經在ImageView控件中顯示圖像，但是當我嘗試將圖像發送到遠程服務器，PHP服務器時，存儲在服務器中的圖像是最小化版本，沒有在imageview控件中捕獲的全尺寸圖像。

public void onClick(View v) { 
      // CALL THIS METHOD TO GET THE URI FROM THE BITMAP 
      Uri tempUri = getImageUri(getApplicationContext(), imagen); 
      imagepath = getRealPathFromURI(tempUri); 
      Log.i("uploadFile", "File Path : " 
        + imagepath); 
      // CALL THIS METHOD TO GET THE ACTUAL PATH 
      //File finalFile = new File(getRealPathFromURI(tempUri)); 

      dialog = ProgressDialog.show(DisplayImgCamActivity.this, "", "Subiendo imagen...", true); 
      //messageText.setText("uploading started....."); 
      new Thread(new Runnable() { 
       public void run() { 
         uploadFile(imagepath);   
       } 
       }).start();    
     } 

public int uploadFile(String sourceFileUri) {   
    String fileName = sourceFileUri; 

    //Log.i("uploadFile", "File Uri : " 
     //  + fileName); 


    HttpURLConnection conn = null; 
    DataOutputStream dos = null; 
    String lineEnd = "\r\n"; 
    String twoHyphens = "--"; 
    String boundary = "*****"; 
    int bytesRead, bytesAvailable, bufferSize; 
    byte[] buffer; 
    int maxBufferSize = 1 * 1024 * 1024; 
    File sourceFile = new File(sourceFileUri); 

    if (!sourceFile.isFile()) { 

     dialog.dismiss(); 

     Log.e("SubirImagen", "No existe la imagen :" + imagepath); 

     runOnUiThread(new Runnable() { 
      public void run() { 
       //messageText.setText("Source File not exist :"+ imagepath); 
       Toast.makeText(DisplayImgCamActivity.this, "No existe imagen a subir", Toast.LENGTH_LONG).show(); 
      } 
     }); 

     return 0; 

    } 
    else

      conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary); 
      conn.setRequestProperty("uploaded_file", fileName); 

      dos = new DataOutputStream(conn.getOutputStream()); 

      dos.writeBytes(twoHyphens + boundary + lineEnd); 
      dos.writeBytes("Content-Disposition: form-data; name=\"uploaded_file\";filename=\"" 
             + fileName + "\"" + lineEnd); 

      dos.writeBytes(lineEnd);

       }

      dos.writeBytes(lineEnd); 
      dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd); 

      // Responses from the server (code and message) 
      serverResponseCode = conn.getResponseCode(); 
      String serverResponseMessage = conn.getResponseMessage();

Answer 1

不知道我理解的問題，但發生的事情是你送的是在ImageView的加載，並且是收到
這恰好是比什麼在ImageView的顯示尺寸更小的PHP的圖像，如果所以相同的是你在應用程序中的圖像很小，會發生什麼是相同的縮放imageview不，如果你可以幫助解決方案，對不起我的英語

編輯：我的意思是，圖像字節如果相同但沒有任何修改，在

Answer 2

那麼，最後我可以結束腳本。最後，我選擇了將圖像存儲在智能手機中的完整路徑，而不是圖像視圖中顯示的圖像。在這種情況下，我可以得到我想要的完整圖像。在圖像視圖中顯示的圖像是存儲在手機中的圖像的最小化版本。
