Android：如何從ImageView上傳照片？

Question

嗨，大家好，我點擊按鈕rent時，如何將圖片上傳到我的網絡主機上的文件管理器？截至目前，我不會從任何事情開始，因爲我試圖以我從圖庫上傳的方式上傳它，但它沒有奏效。你能幫助我嗎？截至目前我打掃我的代碼，這是它

@Override 
public void onClick(View v) { 



    HashMap postData = new HashMap(); 

    postData.put("txtCarModel", tvCarModel.getText().toString()); 
    postData.put("txtCarType", tvCarType.getText().toString()); 
    postData.put("txtCapacity", tvCapacity.getText().toString()); 
    postData.put("txtPlateNumber", tvPlateNumber.getText().toString()); 
    postData.put("image", toString()); 
    postData.put("txtFuelType", tvFuelType.getText().toString()); 
    postData.put("txtOwner", tvPoster.getText().toString()); 


    if (TextUtils.isEmpty(etResDate.getText().toString())) { 
     Toast.makeText(this, "Insert reservation date.", Toast.LENGTH_SHORT).show(); 
     return; 
    } 
    postData.put("txtResDate", etResDate.getText().toString()); 

    if (TextUtils.isEmpty(etResTime.getText().toString())) { 
     Toast.makeText(this, "Insert reservation time.", Toast.LENGTH_SHORT).show(); 
     return; 
    } 
    postData.put("txtResTime", etResTime.getText().toString()); 

    if (TextUtils.isEmpty(etResLocation.getText().toString())) { 
     Toast.makeText(this, "Insert pickup location.", Toast.LENGTH_SHORT).show(); 
     return; 
    } 
    postData.put("txtResLocation", etResLocation.getText().toString()); 


    postData.put("txtRenter", pref.getString("username","").toString()); 


    PostResponseAsyncTask taskPost = new PostResponseAsyncTask(DetailActivity.this, postData, new AsyncResponse() { 
     @Override 
     public void processFinish(String s) { 
      if (s.contains("New records created successfully")) { 
       Log.d(TAG, s); 
       Toast.makeText(DetailActivity.this, "Wait for owners approval", Toast.LENGTH_SHORT).show(); 
       Intent in = new Intent(DetailActivity.this, RenterTabs.class); 
       startActivity(in); 
       finish(); 
      } else { 
       Toast.makeText(getApplicationContext(), "Error", Toast.LENGTH_SHORT).show(); 
      } 

     } 
    }); 

    taskPost.execute("http://carkila.esy.es/rent.php"); 
}

私人無效selectImage（）{
