意圖畫廊的圖像SD卡路徑

Question

我通過意圖開始畫廊，否則它給網格視圖中顯示畫廊的問題。 但我想從圖庫中選擇圖像的實際SD卡路徑，意圖打開。

這裏是代碼..

Intent photoPickerIntent = new Intent(Intent.ACTION_GET_CONTENT); 
    photoPickerIntent.setType("image/jpg"); 
    photoPickerIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/Pictures/image.jpg")); 
    startActivityForResult(photoPickerIntent, 1); 



protected void onActivityResult(int requestCode, int resultCode, Intent intent)  { 
    super.onActivityResult(requestCode, resultCode, intent); 

      if (resultCode == RESULT_CANCELED) { 
      showToast(this,"Activity cancelled"); 
      return; 
      } 
      else if(resultCode == RESULT_OK) { 


      System.out.println("requestCode--"+requestCode); 
      System.out.println("resultCode--"+resultCode); 
      System.out.println("data--"+intent.getData()); 
      Uri uri = intent.getData(); 
      String data = uri.getPath(); 
      System.out.println("uri.getPath()--"+uri.getPath()); 
      System.out.println("type--"+intent.getType()); 
      System.out.println("path--"+Environment.getExternalStorageState()); 


       return; 

       } 

      switch (requestCode) { 
       case CAMERA_ACTIVITY: 
        Bundle b = intent.getExtras(); 
        Bitmap bm = (Bitmap) b.get("data"); 
       //  mImageView.setImageBitmap(bm); // Display image in the View 

        // large image? 
         if (b.containsKey(MediaStore.EXTRA_OUTPUT)) { // large image? 
         Log.i(TAG, "This is a large image"); 
          showToast(this,"Large image"); 
         // Should have to do nothing for big images -- should already saved in MediaStore ... but 
          MediaStore.Images.Media.insertImage(getContentResolver(), bm, null, null); 
          } 
          else { 
           Log.i(TAG, "This is a small image"); 
           showToast(this,"Small image"); 
           MediaStore.Images.Media.insertImage(getContentResolver(), bm, null, null); 
          } 
          break; 
         } 
        } 
       } 

我從意向對象獲取的所有數據。但我想圖像的SD卡路徑，我選擇上傳圖像在服務器..

我怎麼得到這個？

Answer 1

你可能想是這樣的：

Uri uri = (Uri) intent.getExtras().get("android.intent.extra.STREAM"); 

if (intent.getAction().equals(Intent.ACTION_SEND)) 
{ 
    if (uri.getScheme().equals("content")) 
    { 
     Cursor cursor = getContentResolver().query(uri, null, null, null, null); 
     cursor.moveToFirst(); 
     filePath = cursor.getString(cursor.getColumnIndexOrThrow(Images.Media.DATA)); 
    } 
}

本準則可以幫助你

該代碼會彈出一個對話框用相機和畫廊和設備的SD卡來獲取圖像的路徑。
