Creating a simple search functionality

I was trying to understand how to make a search functions in an app. I go through the Creating a Search Interface documentation, but its quite hard and yea i need help. However, i do succeed to just create a search interface, displaying results based from a string arrray. It does work, but it doesnt had any activity behind it or any intent. It more like a simple text-search. I just wondering can i put int that can simultaneously work with string ?
Or any solution and ideas, really appreciate it.
for now here is my homefragment class
package com.example.testtt;
import androidx.cardview.widget.CardView;
import androidx.fragment.app.Fragment;;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;

import android.widget.SearchView;
import androidx.annotation.Nullable;
import java.util.ArrayList;
public class HomeFragment extends Fragment implements View.OnClickListener {
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_home, container, false);
//define
RelativeLayout drawerlayouthome;
ListView list;
ListViewAdapter adapter;
SearchView editsearch;
ArrayList<DoaSearchIndex> arrayList = new ArrayList<DoaSearchIndex>();
String[] doasearchindex = getActivity().getResources().getStringArray(R.array.doasearchindex);
//locatelistview
list = v.findViewById(R.id.searchlistview);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
list.setVisibility(View.INVISIBLE);
}
});
for (int i = 0; i < doasearchindex.length; i++) {
DoaSearchIndex doaSearchIndex = new DoaSearchIndex(doasearchindex[i]);
arrayList.add(doaSearchIndex);
}
//pass result to listviewadapter.class
adapter = new ListViewAdapter(this.getActivity(), arrayList);
//binds adapter to listview
list.setAdapter(adapter);
list.setVisibility(View.INVISIBLE);
//locatesearchview
editsearch = v.findViewById(R.id.searchview);
editsearch.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
if(TextUtils.isEmpty(newText)){
list.clearTextFilter();
adapter.filter("");
list.setVisibility(View.INVISIBLE);
} else {
adapter.filter(newText);
list.setVisibility(View.VISIBLE);
}
return true;
}
});
drawerlayouthome = v.findViewById(R.id.drawer_layouthome);
drawerlayouthome.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
list.setVisibility(View.INVISIBLE);
editsearch.clearFocus();
}
});
//definingcardview
CardView doacard = v.findViewById(R.id.doacard);
CardView ziarahcard = v.findViewById(R.id.ziarahcard);
//setcardviewlistener
doacard.setOnClickListener(this);
ziarahcard.setOnClickListener(this);
return v;
}
#Override
public void onClick(View view) {
Intent i ;
switch (view.getId()) {
case R.id.doacard:
i = new Intent(getActivity(), listdoa.class);
startActivity(i);
break;
case R.id.ziarahcard:
i = new Intent(getActivity(), listziarah.class);
startActivity(i);
break;
}
}
}
and my listviewadapter
package com.example.testtt;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;

public class ListViewAdapter extends BaseAdapter {
//Declare variables first
Context mContext;
LayoutInflater inflater;
private List<DoaSearchIndex> doaSearchIndexList = null;
private ArrayList<DoaSearchIndex> arrayList;
public ListViewAdapter(Context context, List<DoaSearchIndex> doaSearchIndexList) {
mContext = context;
this.doaSearchIndexList = doaSearchIndexList;
inflater = LayoutInflater.from(mContext);
this.arrayList = new ArrayList<DoaSearchIndex>();
this.arrayList.addAll(doaSearchIndexList);
}
public class ViewHolder {
TextView name;
}
#Override
public int getCount() {
return doaSearchIndexList.size();
}
#Override
public DoaSearchIndex getItem(int position) {
return doaSearchIndexList.get(position);
}
#Override
public long getItemId(int position) {
return position;
}
public View getView(final int position, View view, ViewGroup parent) {
final ViewHolder holder;
if (view == null) {
holder = new ViewHolder();
view = inflater.inflate(R.layout.listview_item, null);
// Locate the TextViews in listview_item.xml
holder.name = (TextView) view.findViewById(R.id.name);
view.setTag(holder);
} else {
holder = (ViewHolder) view.getTag();
}
// Set the results into TextViews
holder.name.setText(doaSearchIndexList.get(position).getDoaSearchIndex());
return view;
}
// Filter Class
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
doaSearchIndexList.clear();
if (charText.length() == 0) {
doaSearchIndexList.addAll(arrayList);
} else {
for (DoaSearchIndex wp : arrayList) {
if (wp.getDoaSearchIndex().toLowerCase(Locale.getDefault()).contains(charText)) {
doaSearchIndexList.add(wp);
}
}
}
notifyDataSetChanged();
}
}
and my doasearchindex class
package com.example.testtt;
public class DoaSearchIndex {
private String doaSearchIndex;
public DoaSearchIndex(String doaSearchIndex) {
this.doaSearchIndex = doaSearchIndex;
}
public String getDoaSearchIndex() {
return this.doaSearchIndex;
}
}

my paystack payment gateway popup is not showing/poping up

This code is not working and my paystack payment gateway is not showing, though it displays the spinner but will not show the form for card input.
Please I need a complete code that will help me get my job done:
webView.setWebChromeClient(new WebChromeClient() {
#Override
public boolean onCreateWindow(WebView view, boolean isDialog,
boolean isUserGesture, Message resultMsg) {
WebView newWebView = new WebView(WebpageActivity.this);
newWebView.getSettings().setJavaScriptEnabled(true);
newWebView.getSettings().setSupportZoom(true);
newWebView.getSettings().setBuiltInZoomControls(true);
newWebView.getSettings().setPluginState(PluginState.ON);
newWebView.getSettings().setSupportMultipleWindows(true);
view.addView(newWebView);
WebView.WebViewTransport transport = (WebView.WebViewTransport) resultMsg.obj;
transport.setWebView(newWebView);
resultMsg.sendToTarget();
newWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
});
return true;
}
}
});

Well, this code should work when pasted on your MainActivity file of your android webview project.
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.net.Uri;
import android.webkit.WebViewClient;
import android.webkit.WebSettings.PluginState;
public class MainActivity extends Activity {
private WebView webView = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.webView = (WebView) findViewById(R.id.webView);
WebSettings webSettings = webView.getSettings();
webView.setInitialScale(1);
webSettings.setJavaScriptEnabled(true);
webSettings.setLoadWithOverviewMode(true);
webSettings.setUseWideViewPort(true);
webSettings.setAllowFileAccess(true);
webSettings.setAllowContentAccess(true);
webSettings.setSupportZoom(true);
webSettings.setBuiltInZoomControls(true);
webSettings.setPluginState(PluginState.ON);
webSettings.setSupportMultipleWindows(true);
webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
WebViewClientImpl webViewClient = new WebViewClientImpl(this);
webView.setWebViewClient(webViewClient);
webView.loadUrl("https://www.your_url.com/");
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && this.webView.canGoBack()) {
this.webView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
public class WebViewClientImpl extends WebViewClient {
private Activity activity = null;
public WebViewClientImpl(Activity activity) {
this.activity = activity;
}
#Override
public boolean shouldOverrideUrlLoading(WebView webView, String url) {
if(url.indexOf("your_url") > -1 ) return false;
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
activity.startActivity(intent);
return true;
}
}
}
Now, after pasting the above code you need to use the PHP paystack integration this time and not the javascript paystack integration initialization and callback functions.
At this point you only need to worry about your sessions.
Tested And Confirmed.

Can you help me to fix this problem, please?

In the doc at step 4, you also have to make your MainActivity extend FragmentActivity:
public class MainActivity extends FragmentActivity implements DefaultHardwareBackBtnHandler { // ! extends from FragmentActivity
(yours only extend Activity)

Want to pass the cookies to the webview to load a webpage

I had Successful login to a website using jsoup and I obtained cookies from Jsoup cookies function in Map but I am struck at something.After successful login I Want to open a webpage of the website in the webview but the webpage redirects to the login page because cookies are not successfully passed to the webview and I don't know why. The page wants cookies of successful login to load that page
Here is the login page url.

I have passed the saved cookie to the activity that load the webpage in webivew.. Here is the other activity;
Wee.java

import android.webkit.WebView;
import android.webkit.WebViewClient;

/**

public class wee extends Activity {
String url= "http://111.68.99.8/StudentProfile/PersonalInfo.aspx";
HashMap<String ,String> hashMap;
Map<String,String> map;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout);
Intent intent = getIntent();
hashMap = (HashMap<String,String>) intent.getSerializableExtra("hashMap");
WebView webView = (WebView) findViewById(R.id.webviewe);
webView.setWebViewClient(new WebViewClient());
webView.loadUrl(url,hashMap);
}
}
Is there any way that I can view that webpage without logging in again to the webview?

Haven't tested it, but using CookieManager ahould work.
Usage should be something like this:
CookieSyncManager.createInstance(this);
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.removeAllCookie(); //optional
cookieManager.setAcceptCookie(true);
Then loop over your cookies using the setCookie method.
Note: If useing lollipop and up you should also use setAcceptThirdPartyCookies.
Good luck.
