Android menu crashs application

I have the following in my code and I want to switch to this new activity when I select it from the menu, but the app just keeps closing:
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.mi_baas:
startActivity(new Intent("com.my.project.BAAS"));
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
Please help, 2 days so far.....

You have to pass context and class which is to be opened.
Your code should be like this.
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.mi_baas:
startActivity(new Intent(getContext(),BAAS.class));
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}
Hope it helps:)

How to handle back arrow event in a SearchView

How can I handle the click event on the back arrow in the searchview widget:
I tried this code but it doesn't work:
searchtollbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.d(TAG, "back arrow clicked");
}
});
also I tried this one:
MenuItemCompat.setOnActionExpandListener(item_search, new
MenuItemCompat.OnActionExpandListener() {
#Override
public boolean onMenuItemActionCollapse(MenuItem item) {
// Do something when collapsed
return true;
}
#Override
public boolean onMenuItemActionExpand(MenuItem item) {
// Do something when expanded
return true;
}
});
The problem with the above code is that calling onMenuItemActionCollapse() method also executes onQueryTextChange() which is undesirable.
So some help please.

To handle that you have to override onOptionsItemSelected method.
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case android.R.id.home:
// handle back event.
return true;
default:
return super.onOptionsItemSelected(item);
}
}

Try with
MenuItem item = menu.findItem(R.id.action_search);
SearchView searchView = new SearchView(((MainActivity) mContext).getSupportActionBar().getThemedContext());
item.setOnActionExpandListener(new MenuItem.OnActionExpandListener() {
#Override
public boolean onMenuItemActionExpand(MenuItem menuItem) {
Log.d( TAG, "expand" );
return true;
}
#Override
public boolean onMenuItemActionCollapse(MenuItem menuItem) {
Log.d( TAG, "collapse" );
return true;
}
});

Hide or Show a Menu Item if Webview Class Activated?

I am trying to disable programmatically a menu item if WebView class is not activated.
I tried this code:
#Override
public boolean onPrepareOptionsMenu(Menu menu)
{
super.onPrepareOptionsMenu(menu);
MenuItem item = menu.findItem(R.id.itemRefresh);
if (WebViewFragment.viewContentWebView.isActivated()){
item.setVisible(true);
item.setEnabled(true);
} else
{
item.setVisible(true);
item.setEnabled(false);
}
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
switch (item.getItemId()) {
case R.id.itemRefresh:
WebViewFragment.viewContentWebView.reload();
return true;
case R.id.itemAdd:
//oke im gonna write here
return true;
case R.id.itemHelp:
// ok ok i will
return true;
default:
return true;
}
}
In Eclipse I don't get any error msg but on real device App blocks itself.
I think I'm doing something wrong in IF-ELSE statement part.
Thank you.

Searchview closing issue

I want to handle collapsing state but I can not handle onActionExpandListener. I use actionbarsherlock and here are my codes. Where do I make mistake?
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getSupportMenuInflater().inflate(R.menu.main, menu);
menu.getItem(0).setVisible(aramaOnOff);
menu.getItem(1).setVisible(filterOnOff);
SearchView searchView = (SearchView)menu.findItem(R.id.imgBuyutec).getActionView();
searchView.setOnQueryTextListener(this);
searchViewItem = menu.findItem(R.id.imgBuyutec);
searchViewItem.setOnActionExpandListener(new MenuItem.OnActionExpandListener() {
#Override
public boolean onMenuItemActionExpand(MenuItem item) {
// TODO Auto-generated method stub
return true;
}
#Override
public boolean onMenuItemActionCollapse(MenuItem item) {
return true;
}
});
return true;
}

Use appcompat-v7 , http://developer.android.com/guide/topics/ui/actionbar.html
and then use the following code,
MenuItemCompat.setOnActionExpandListener(searchViewItem,new MenuItemCompat.OnActionExpandListener() {
#Override
public boolean onMenuItemActionExpand(MenuItem item) {
//whatever
return true;
}
#Override
public boolean onMenuItemActionCollapse(MenuItem item) {
//whatever
return true;
}
});

Menu doesn't appear after linking to another page with phonegap

I use phonegap,
When linking to another page with simple href my menu stop working.
In my Java class I override onKeyDown() and return false for menu button
#Override
public boolean onKeyDown(int i,KeyEvent e){
if (i==KeyEvent.KEYCODE_MENU){
return false;
}else{
return true;
}
}
When I loadUrl from the java class I can open the menu (in about.html)
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.exit:
this.finish();
return true;
case R.id.about:
super.loadUrl("file:///android_asset/www/about.html");
return true;
default:
return super.onOptionsItemSelected(item);
}
}
