如何选择照片并从片段中打开图库？

Question

如何在Android Studio中使用Profile Fragment在图库中显示图像？

我使用imageview（ivGallery）转到图库，所选图片将出现在（ivProfilePicture）中。

• 首先你打电话的意图

  Intent i = new Intent(Intent.ACTION_PICK, 
  android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
  startActivityForResult(i, RESULT_LOAD_IMAGE); 
  

• 然后你会得到OnActivityResult

  @Override 
  protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
  super.onActivityResult(requestCode, resultCode, data); 
  if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) { 
      Uri selectedImage = data.getData(); 
      String[] filePathColumn = { MediaStore.Images.Media.DATA }; 
      Cursor cursor = getContentResolver().query(selectedImage,filePathColumn, null, null, null); 
      cursor.moveToFirst(); 
      int columnIndex = cursor.getColumnIndex(filePathColumn[0]); 
      String picturePath = cursor.getString(columnIndex); 
      cursor.close(); 
      ImageView imageView = (ImageView) findViewById(R.id.imgView); 
      imageView.setImageBitmap(BitmapFactory.decodeFile(picturePath)); 
      }  
  }
