Webview is blank or loading same page for different urls

Webview is blank or loading same page for different urls - java

A search api is returning me some meta data i.e a url "eventURL" and trackbackurl i.e "trackBack". I am placing the data in the listview, each row containing some data and a unique url and trackback url.When user taps on the row in the listview, a alert dialog is displayed presenting user 2 options. Clicking on option 1 should launch trackback url in a webview while clicking on second opion should launch eventURL in a webview.I have created a WebViewActivity for it,Problem is that my webview is always blank.

WebViewActivity
package my.stayactive.plan;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class WebViewActivity extends StayActiveActivity {
private WebView webView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
webView = (WebView) findViewById(R.id.webView);
WebSettings setting = webView.getSettings();
setting.setJavaScriptEnabled(true);
if (url != null && url.length()>0) {
webView.loadUrl(url);
}
}
}

You didn't pass URL to your WebViewActivity. To do that:
Before calling startActivity(), attach your URL to the intent with setData().
In onCreate() of WebViewActivity, retrieve the URL with getData(), then load it.
Or search for putExtra(...). You can transfer a number of data with Intent.
— edited —
Example:
To set data:
import android.net.Uri;
//...
Intent intent = new Intent (StayActiveActivity.this, WebViewActivity.class);
intent.setData(Uri.parse("your-url"));
StayActiveActivity.this.startActivity(intent);
To retrieve data:
//...
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//...
Uri uri = getIntent().getData();
//...
webView.loadUrl(uri.toString());
}

My guess is that your URLs are redirecting and that you aren't handling the redirects so nothing is being shown.
try adding this to your webview activity:
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return false;
}
});
Also it would be a good idea since you have an if statement in your WebView activity to log the url so that you can be certain that it is actually making it in to the activity correctly. If not the web view would never load anything.
EDIT: actually upon closer look it doesn't seem like you're setting the 'url' variable anywhere so it would be null, thus not calling your loadUrl method because of the if statement.

favorite Recycler view updates only on relaunching app

I developed a word app that contains English vocabularies and users can add their favorite word by clicking on a floating button. Every time my favorite list has at list one item it is updated but when it's empty it doesn't show anything but when I run app again list updates.
if you need any code let me know to send it .
UPDATE:

In your FloatingActionButton onClick method after you save the new item in your database, insert your new item into your recyclerview datasource list and call notifyDatasetChanged() on the adapter.

Choice 1: in onResume() stub of MainActivity, call selectList() and selectFavorite() and then load the PageFragment again so that the new list is loaded properly.
This is the shortest wayout but this approach is very much unoptimized and is not recommended.
Choice 2: You will have to insert the new item in database as well as add it to the List and then call notifyDatasetChanged
In MainActivity within methods selectList() and selectFavorite() after you perform list.add(struct) and favourite.add(struct) respectively, you will have to call notifyDatasetChanged() for the Adapter.
But the problem is your RecyclerView is in the PageFragment whereas you're populating the list in MainActivity.
So move your selectList() and selectFavorite() to PageFragment where you first initialize the RecylerView then, set the Adapter and then populate the list and finally call notifyDatasetChanged() on your adapters.

Method OnItemClickListener from JSONParser override OnItemLongClickListener from another activity

I'm trying to create the favorites list from Json Objects which I received by URL.
When I got Json array, I defined methods OnItemLongClickListener and OnItemClickListener that get different things:
The OnItemClickListener method has to open another activity with description of product
The OnItemLongClickListener method has to add product to favorite list
The Problem that method OnItemClickListener which I defined in MainActivity is override method OnItemLongClickListener which I defined in FragmentActivty and the method OnItemLongClickListener doesn't work at all then I tried to define both methods in FragmentActivity but after that both methods don't work at all.
Is there any way to determine this problem?

.getText().toString();
String site = ((TextView) view.findViewById(R.id.site))
.getText().toString();
String logoURL = String.valueOf(((ImageView) view.findViewById(R.id.logoURL)));
// Starting single contact activity
Intent in = new Intent(getApplicationContext(),
SingleContactActivity.class);
in.putExtra(TAG_NAME, name);
in.putExtra(TAG_PHONE, phone);
in.putExtra(TAG_SITE, site);
in.putExtra(TAG_LOGO, logoURL);
startActivity(in);
}
});
listView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view,
int position, long id) {
ImageView button = (ImageView) view.findViewById(R.id.favorite_button);
String tag = button.getTag().toString();
if (tag.equalsIgnoreCase("grey")) {
sharedPreference.addFavorite(MainActivity.this, airlinesList.get(position));
Toast.makeText(MainActivity.this,
MainActivity.this.getResources().getString(R.string.add_favr),
Toast.LENGTH_SHORT).show();
button.setTag("red");
button.setImageResource(R.drawable.heart_red);
} else {

now it works

Android: item list click on JSON generated list view - unable to click

Thanks in advance.
SOLUTION FOUND:
add this into onCreate method
list = (ListView) findViewById(R.id.listView1);
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Log.e("item clicks", "selected: " + position);
String item = list.getItemAtPosition(position).toString();
String contactNum = ((TextView)view.findViewById(R.id.listPhone)).getText().toString();
Log.e("phone number", contactNum);
Intent intent = new Intent(Intent.ACTION_CALL);
intent.setData(Uri.parse("tel:" + contactNum));
startActivity(intent);
}
});
thanks to Kunu for the help

Use this on your onCreate()
list.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View view, int position,
long id) {
Log.e("item clicks", "selected: " + position);
String contactNum = ((TextView)view.findViewById(R.id.listPhone)).getText().toString();
phoneCall(contactNum);
}
});
and don't forget to import import android.widget.AdapterView.OnItemClickListener;
After retrieving the number try this to make a call
public void phoneCall(String number)
{
String phoneCallUri = "tel:"+number;
Intent phoneCallIntent =new Intent(Intent.ACTION_CALL);
phoneCallIntent.setData(Uri.parse(phoneCallUri));
startActivity(phoneCallIntent);
}

to set the itemClickListener use :
listView.setOnItemClickListener(ActivityName.this);
Override the method, and also inside the xml
set the focusableInTouchMode to false, and also focusable to false for the textviews
Hope that helps

in OnCreate list.setOnItemClickListener(new OnItemClickListener() {});and then Add unimplement method
public class MainActivity extends Activity {
ListView lView ;
String[] ara={"a","b","c","d","e","f"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lView=(ListView)findViewById(R.id.listView1);
ListAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1,ara);
lView.setAdapter(adapter);
lView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
}});
}
}

how to use content provider to access shared preferences

i have a registration app in the making where the user registers the data and on the other end the data can be shown and viewed and manipulated , i am using shared preferences method as shown below to write and access data (you can see them in DataEntry.java & DataManipulation.java shown below) but i want to use content provider method to manipulate data like quering or inserting or deleting....is there a way to do this and if yes can you please tell me how?

Android parsing XML with YQL data

I am trying to do a simple APP that parses Currency data from Yahoo finance using their YQL query language. I tried parsing data with Google's finance API and it works fine but when I try it with Yahoo's URL it freezes before I even get to my parsing algorithm which is very strange.
