Easy share action is not working in WebView Android app

I have been trying almost everything to get this share button to work. The button is placed right but it's not getting clicked and the share window is not showing.
Secondly, I want it to share Web URL of the page when clicked and I am also unable to understand how to do that.
Moreover, I do not want the button to be hidden in the Action settings. I want it to be displayed on the top bar, that's what's my main problem is.

First, the button is not clickable.
Second, how to share the current page URL?
These are the two queries which I am unable to solve.

Share Action provider not working

I have created an Android app.
It has a main activity (with fragment) and a detailed activity (with fragment)
In the detailed activity fragment, I want to add a share button which will share some fixed text (say - "Hello").
The share button appears in the app but nothing happens when I click it.
I want to share plain fixed text.
Here is the menu_detail.xml file:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item android:id="#+id/action_share"
android:title="#string/action_share"
app:showAsAction="always"
app:actionProviderClass="android:support.v7.widget.ShareActionProvider" />
</menu>
And here is the DetailActivityFragment.java file:
package com.blogspot.amangoeliitb.amansblog;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.view.MenuItemCompat;
import android.support.v7.widget.ShareActionProvider;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebView;
import android.widget.TextView;
public class DetailActivityFragment extends Fragment {
public static final String LOG_TAG = DetailActivityFragment.class.getSimpleName();
public DetailActivityFragment() {
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.menu_detail, menu);
MenuItem menuItem = menu.findItem(R.id.action_share);
ShareActionProvider mShareActionProvider =
(ShareActionProvider) MenuItemCompat.getActionProvider(menuItem);
if(mShareActionProvider != null) {
mShareActionProvider.setShareIntent(createShareForecastIntent());
}
else
Log.d(LOG_TAG, "Share action provider is null");
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_detail, container, false);
Intent intent = getActivity().getIntent();
Bundle extras = intent.getExtras();
String title = extras.getString("TITLE") ;
String content = extras.getString("CONTENT") ;
((TextView) rootView.findViewById(R.id.post_title)).setText(title);
((WebView) rootView.findViewById(R.id.post_content)).loadData(content, "text/html", "UTF-8");
return rootView;
}
private Intent createShareForecastIntent() {
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
shareIntent.setType("text/plain");
shareIntent.putExtra(Intent.EXTRA_TEXT, "Hello");
return shareIntent;
}
}

I was also working on the same problem.
There is a minute error in your code in menu_detail.xml file. In this line
app:actionProviderClass="android:support.v7.widget.ShareActionProvider"
Remove the ":" after android and replace with a full stop. So it should be
app:actionProviderClass="android.support.v7.widget.ShareActionProvider"
Everything else is good. And it is working for me.

SharedPreference values not available between activities

I have 2 activities. One is the main activity. One is the Preference activity. I'm trying to change the background color of the activity based on the color selected in a RadioGroup in the Preference activity.
This is the class file for the main activity.
package com.example.mycsimodules;
import android.support.v7.app.ActionBarActivity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.ArrayAdapter;
public class ModList extends ActionBarActivity {
SharedPreferences savedData;
private String[] moduleArray = { "COMP 41600", "COMP 41620", "COMP 47330","COMP 30160", "COMP 30500", "COMP 40725", "COMP 41100", "COMP 41110" };
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_mod_list);
savedData=getSharedPreferences("MyPrefs",0);
String colorMine=savedData.getString("color", "deflt");
TextView head=(TextView) findViewById(R.id.mymodlist);
head.setText(colorMine);
ArrayAdapter<String> moduleAdapter = new ArrayAdapter<String>(this, R.layout.activity_list_view, R.id.list1, moduleArray);
final ListView list = (ListView) findViewById(R.id.mod_list);
list.setAdapter(moduleAdapter);
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.mod_list, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
Intent i=new Intent(this, Preferences.class);
startActivity(i);
return true;
}
return super.onOptionsItemSelected(item);
}
This is the class file for the Preference class.
package com.example.mycsimodules;
import android.support.v7.app.ActionBarActivity;
import android.annotation.SuppressLint;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.TextView;
public class Preferences extends ActionBarActivity implements OnClickListener{
RadioGroup colorList;
Button saveButton;
SharedPreferences savedData;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_preferences);
colorList=(RadioGroup) findViewById(R.id.colorRadioGroup);
saveButton=(Button) findViewById(R.id.bSave);
saveButton.setOnClickListener(this);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.preferences, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
#SuppressLint("NewApi") #Override
public void onClick(View v) {
// TODO Auto-generated method stub
if(v==saveButton){
RadioButton myColor=(RadioButton) findViewById(colorList.getCheckedRadioButtonId());
String colorSelected=myColor.getText().toString();
TextView label=(TextView) findViewById(R.id.the_color_is);
label.setText(colorSelected);
savedData=getSharedPreferences("MyPref", 0);
SharedPreferences.Editor editor=savedData.edit();
editor.putString("color", colorSelected);
editor.apply();
editor.commit();
}
}
}
I haven't actually done the background color part. I'm just trying to display the value in a TextView currently. But it shows only the default value all the time. What I'm trying to do is.
Click on Settings.
Click on RadioButton for color desired.
Click on Save button.
Click on back key to return to main activity.
I'm pretty new to this and might be doing something wrong. But I just can't figure out what it is.

savedData=getSharedPreferences("MyPrefs",0);
it's diferent from
savedData=getSharedPreferences("MyPref", 0);
Use the same file when you open your SharedPreferences

Search view widget and Icon not showing up in the action bar

I am a beginner to Android. Trying to add a search a widget in the action bar.
Here is my menu file code ("main_acitivity.xml"):
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- Search, should appear as action button -->
<item android:id="#+id/action_search"
android:icon="#drawable/ic_search"
android:title="#string/action_search"
android:showAsAction="always"
android:actionViewClass="android.support.v7.widget.SearchView" />
<!-- Settings, should always be in the overflow -->
<item android:id="#+id/action_settings"
android:title="#string/action_settings"
android:showAsAction="never" />
</menu>
My MainActivity class code is:
package com.example.fragment;
import android.app.ActionBar;
import android.app.Activity;
import android.content.Intent;
import android.os.Build;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.widget.EditText;
public class MainActivity extends ActionBarActivity {
public final static String EXTRA_MESSAGE = "com.example.fragment.MESSAGE";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
MenuInflater inflater= getMenuInflater();
inflater.inflate(R.menu.main_activity,menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle presses on the action bar items
switch (item.getItemId()) {
case R.id.action_search:
return true;
case R.id.action_settings:
return true;
default:
return super.onOptionsItemSelected(item);
}
}
public void sendMessage(View view){
Intent intent= new Intent(this,DisplayMessageActivity.class);
EditText editText= (EditText) findViewById(R.id.edit_message);
String message = editText.getText().toString();
intent.putExtra(EXTRA_MESSAGE, message);
startActivity(intent);
}
}
I have tried "android.widget.SearchView" as well but it is not even showing the icon. Could you please advise what I am doing wrong ?

you missed these:
xmlns:yourappname="http://schemas.android.com/apk/res-auto"
and
yourappname:showAsAction="always"
yourappname:actionViewClass="android.support.v7.widget.SearchView"/>

Menu items won't show up in the actiobar

UPDATE:
It works on the tab, but on the phone it's overlayed for some reason
I have a question regarding the menu items android uses for the ActionBar, I have a custom background for my actiobar (a picture) and set it in the code here. That piece of code works fine. But when I try to add a menu item, it fails.
What I want is fairly simple, I want a button that says "save product as favorite" at the bottom of the screen, like the bottom-actionbar. But when I try to add the button as menu item it won't show up, nothing changes.
The log tells me the onCreateOptionsMenu() method is in fact executed. Any ideas?
This is the activity I want the menu for:

// Handle item selection
switch (item.getItemId()) {
case R.id.save:
Log.i("menu", "werkt");
return true;
default:

}
}
}
This is the menu XML:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="#+id/save"
android:title="Opslaan in favorieten" >
</item>
</menu>

I think you need to fix this:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
Log.i("hallo", "hoi");
inflater.inflate(R.layout.product_menu, menu); // <- this is wrong
return true;
}
Instead of R.layout.product_menu, it should refer to R.menu.your_desired_menu

If you want to show your menu item in the action bar, set the android:showAsAction property of your item in product_menu.xml;
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/item1"
android:title="Save"
android:showAsAction="always" />
</menu>
You can set this property to:
ifRoom
never
withText
always
collapseActionView
I hope this helps you!
