文本在android活动中加载延迟

Question

下面给出的是（onCreate）代码，用于在我的Android应用程序的屏幕上显示一些信息。此活动将加载到另一个活动中触发的事件中。问题是加载此屏幕时。它首先加载空白屏幕，然后延迟呈现相关文本。最终用户可以注意到这种延迟，这让他们觉得屏幕加载了两次。对此有什么解决方案吗？

@Override
            protected void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.activity_end);
                CommonUtils.changeActionBarColor(getSupportActionBar());

                //get the respective child object which has to be displayed in the GUI
                String childObjectKey = getIntent().getStringExtra(CHILD_OBJECT_KEY);
                // Single method pop(), for both pushWeak() and pushStrong()
                endObject = (IPEnd) ASFObjectStore.getDefault().pop(childObjectKey);

                this.setTitle(endObject.getPathwayName());

                //endWebView
                WebView endWebView=(WebView)findViewById(R.id.endWebView);
                String tempEndString = HTMLConverter.changeFontSize(endObject.getEndText(), UtilConstants.GLOBAL_FONT_SIZE);
                tempEndString = HTMLConverter.changeFontFamily(tempEndString,UtilConstants.GLOBAL_FONT_FAMILY);
                endWebView.loadData(tempEndString,"text/html;charset=utf-8","UTF-8");

                //overall image button
                ImageButton overviewButton = (ImageButton) findViewById(R.id.endOverviewImageButton);
                overviewButton.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {

                        //showOverviewImage("Bleeding (First Trimester).jpg");
                        LayoutInflater layoutInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                        View view = layoutInflater.inflate(R.layout.image_popup, (ViewGroup) findViewById(R.id.popup_element));
                        Button btnClosePopup = (Button) view.findViewById(R.id.cancel_button);
                        String imageFileName = endObject.getPathwayName()+ UtilConstants.IMAGE_FILE_EXTENSION;

                        CommonUtils utils = new CommonUtils();
                        utils.showOverviewImage(imageFileName, getWindowManager(), getApplicationContext(), layoutInflater, view,End.this);
                    }
                });

            }
