super.onCreate(savedInstanceState);
//setContentView(R.layout.activity_main);
parent=new RelativeLayout(this);
RelativeLayout.LayoutParams helpPopupLayout_params=new RelativeLayout
.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT,ViewGroup.LayoutParams.FILL_PARENT);
parent.setLayoutParams(helpPopupLayout_params);
parent.setPadding(0, 0, 0, 0);
parent.setBackgroundColor(Color.TRANSPARENT);
parent.setBackgroundColor(Color.RED);
child=new RelativeLayout(this);

child_params.rightMargin = rightMargin;
child.setLayoutParams(child_params);
parent.addView(child,child_params);
WebView_params=new RelativeLayout

Hi guys I'm having problem with the jfeistein sliding menu. I have correctly imported it but i have only a problem. When I click on the "test" item it opens the related fragment but it doesn't autoclose the menu as it should.
MAINACTIVITY
Code:
public class MainActivity extends Activity {
private SlidingMenu slidingMenu ;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
slidingMenu = new SlidingMenu(this);
slidingMenu.setMode(SlidingMenu.LEFT);
slidingMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);
slidingMenu.setShadowWidthRes(R.dimen.slidingmenu_shadow_width);
slidingMenu.setShadowDrawable(R.drawable.slidingmenu_shadow);
slidingMenu.setBehindOffsetRes(R.dimen.slidingmenu_offset);
slidingMenu.setFadeDegree(0.35f);
slidingMenu.attachToActivity(this, SlidingMenu.SLIDING_CONTENT);
slidingMenu.setMenu(R.layout.slidingmenu);
getActionBar().setDisplayHomeAsUpEnabled(true);
}
@Override
public void onBackPressed() {
if ( slidingMenu.isMenuShowing()) {
slidingMenu.toggle();
}
else {
super.onBackPressed();
}
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ( keyCode == KeyEvent.KEYCODE_MENU ) {
slidingMenu.toggle();
return true;
}
return super.onKeyDown(keyCode, event);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
this.slidingMenu.toggle();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
SLIDING MENU FRAGMENT
Code:
public class SlidingMenuFragment extends Fragment implements ExpandableListView.OnChildClickListener {
private SlidingMenu slidingMenu ;
private ExpandableListView sectionListView;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
List<Section> sectionList = createMenu();
View view = inflater.inflate(R.layout.slidingmenu_fragment, container, false);
this.sectionListView = (ExpandableListView) view.findViewById(R.id.slidingmenu_view);
this.sectionListView.setGroupIndicator(null);
SectionListAdapter sectionListAdapter = new SectionListAdapter(this.getActivity(), sectionList);
this.sectionListView.setAdapter(sectionListAdapter);
this.sectionListView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
@Override
public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {
return true;
}
});
this.sectionListView.setOnChildClickListener(this);
int count = sectionListAdapter.getGroupCount();
for (int position = 0; position < count; position++) {
this.sectionListView.expandGroup(position);
}
return view;
}
private List<Section> createMenu() {
List<Section> sectionList = new ArrayList<Section>();
Section oDemoSection = new Section("Demos");
oDemoSection.addSectionItem(101,"Test", "lol");
oDemoSection.addSectionItem(102, "Airport (AsyncTask)", "lol");
Section oGeneralSection = new Section("General");
oGeneralSection.addSectionItem(201, "Settings", "lol");
oGeneralSection.addSectionItem(202, "Rate this app", "lol");
oGeneralSection.addSectionItem(203, "Eula", "lol");
oGeneralSection.addSectionItem(204, "Quit", "lol");
sectionList.add(oDemoSection);
sectionList.add(oGeneralSection);
return sectionList;
}
public void toggle() {
slidingMenu.toggle();
}
@Override
public boolean onChildClick(ExpandableListView parent, View v,
int groupPosition, int childPosition, long id) {
Fragment fragment=null;
switch ((int)id) {
case 101:
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.frame_container, new Net()).commit();
break;
case 102:
//TODO

case 201:
//TODO

1. Map Creation
This section describes how to create a simple web-based map using the HUAWEI Map Kit API for JavaScript.
1. Create an HTML file and declare the following content in the file header so that the file is supported in most browsers:
Code:
<!DOCTYPE html>
2. Add the style tag pair in the head tag pair to set the map container dimensions.
Code:
<head>
<meta charset="UTF-8">
<style>
#map {
height: 800px;
width: 80%;
margin: 0 auto;
}
</style>
</head>
3. Provide the HUAWEI Map Kit API file. The key must be transcoded using the URL.
Code:
<script src="https://mapapi.cloud.huawei.com/mapjs/v1/api/js?callback=initMap&key=API KEY"></script>
4. Create map container elements in the body.
Code:
<body>
<div id="map"></div>
</body>
Create a script for initializing the map. The following sample code is to create a map with Paris as the center and a zoom level of 8:
Code:
<script>
function initMap() {
var mapOptions = {};
mapOptions.center = {lat: 48.856613, lng: 2.352222};
mapOptions.zoom = 8;
mapOptions.language='ENG';
var map = new HWMapJsSDK.HWMap(document.getElementById('map'), mapOptions);
}
</script>
5. View the created map.

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
2. Map Attribute
You can modify the attributes of a map, such as the map center, zoom coefficient, and map heading. The following sample code is to modify the map center:
Code:
<tr>
<td>Latitude:</td>
<td><input id="latInput" type="text" value="48.95"/></td>
</tr>
<tr>
<td>Longitude:</td>
<td><input id="lngInput" type="text" value="2.35"/></td>
</tr>
Code:
var lat = Number(document.getElementById("latInput").value);
var lng = Number(document.getElementById("lngInput").value);
map.setCenter({lat: lat, lng: lng});
The following table describes the map attributes that can be customized.
I want to develop the function of recognizing bank card numbers. The recognition effect of card.io is much better for cards with raised numbers than those without raised numbers. What other open-source projects can be used to recognize bank card numbers? Here I'd like to share with you the bank card recognition service of HUAWEI ML Kit that I once used in one of my projects. It is free of charge. This service can correctly recognize the card numbers and validity periods of popular cards such as JCB, China UnionPay, American Express, Visa, and Mastercard, regardless of whether the card numbers are raised. The size of the SDK is about 3 MB, which is smaller than that of card.io.
The integration procedure is as follows:
Step 1: Set recognition parameters and call the API for recognition.
Code:
private void startCaptureActivity(MLBcrCapture.Callback callback) {
MLBcrCaptureConfig config = new MLBcrCaptureConfig.Factory()
// Specify that only the card number and validity period are recognized and returned.
.setResultType(MLBcrCaptureConfig.RESULT_SIMPLE)
// Set the display orientation of the recognition screen to be self-adaptive.
.setOrientation(MLBcrCaptureConfig.ORIENTATION_AUTO)
.create();
MLBcrCapture bankCapture = MLBcrCaptureFactory.getInstance().getBcrCapture(config);
bankCapture.captureFrame(this, callback);
}
Step 2: Obtain the recognition result.
Code:
@Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.detect:
startCaptureActivity(callback);
break;
default:
break;
}
}
As shown in the following figure, the recognition speed is fast. The card can be quickly recognized as long as it is in the scanning box, even if the card is not placed in a proper position. This service does not require the user to align the card to the boundaries.

Question:
How to use LayaAir IDE to split the package of a quick game and load subpackages?
Guide:
Splitting the package of a Huawei quick game and loading its subpackages help reduce the traffic and time required for app download. By doing so, you can choose to load or download specific subpackages, instead of the whole package at a time.
Procedure:
1. Release a subpackage in LayaAir IDE.
To split a package, select Set the subcontract during project release, as shown in the following figure.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Then, click the plus sign (+) below. The following window is displayed. Set the subpackage name and the corresponding folder.
2. Configure subpackage information in the manifest file.
You also need to set parameters for the subpackages in the manifest.json file. The sample code is as follows:
Note: If you split a resource package manually, the values of resource should end with a slash (/). In addition, a game.js file must exist in the directory. (Skip this step if you let LayaAir IDE split the package for you.)
XML:
subpackages:[
{
"name":"subpackageName1",// Subpackage name.
"resource":"subpackagePath1"// Corresponding subpackage directory.
},
{
"name":"subpackageName2", // Subpackage name.
"resource":"subpackagePath2"// Corresponding subpackage directory.
}
]
3. Apply specific subpackages.
The sample code for using specific subpackages is as follows:
JavaScript:
var task = hbs.loadSubpackage({
subpackage:'subpackageName1',
success : function () {
console.log("loadSubpackage success" );
},
fail:function(){
console.log("loadSubpackage fail");
},
complete:function() {
console.log("loadSubpackage complete");
}
});
task.onprogress(
callback(res) {
console.log("onProgress" + JSON.stringify(res));
}
);
PHP — Signature Verification for HUAWEI IAP
Background
If you integrate the HMS SDK 3.x, and after a successful purchase, you can obtain the purchase data InAppPurchaseData and its signature data from the PurchaseResultInfo object. You need to use the public key allocated by AppGallery Connect to verify the signature.
For details, check this document:
https://developer.huawei.com/consumer/en/doc/development/HMSCore-Guides/dev-guide-0000001050130254#EN-US_TOPIC_0000001050130254__section183174113342
Code Development
I wrote the sample code to verify the obtained purchase data, its signature and the public key for your reference. Hope it can help you with problem locating.
Sample code:
PHP:
<?php
// Actual payment callback result. Copy the original data without any processing.
// Here, I replaced some personal information with xxxx.

Running the Code
Search for an online code runner that supports PHP. For example:
https://tool.lu/en_US/coderunner/
If the value 0 is returned, everything is normal.
