Android Search Activity in Single Activity

THANKS, This has worked for me.

Manifest:

        <activity
        android:name=".Buscar"
        android:configChanges="orientation|screenSize"
        android:label="@string/title_activity_buscar"
        android:launchMode="singleTop">

        <intent-filter>
            <action android:name="android.intent.action.SEARCH" />
        </intent-filter>
        <meta-data
            android:name="android.app.searchable"
            android:resource="@xml/searchable" />
    </activity>

Activity:

    @Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    // getIntent() should always return the most recent
    setIntent(intent);

    query = intent.getStringExtra(SearchManager.QUERY);
    mysearch(query);

}

Please try to add the following attribute to your <activity> in your manifest file:

android:launchMode="singleTop"

This will make the same activity to receive the search intent.

More info here: http://developer.android.com/guide/topics/manifest/activity-element.html

Also, you have <intent-filter> declared twice, you should merge it into one element.

From Setting Up the Search Interface in the Android Documentation:

In your searchable activity, handle the ACTION_SEARCH intent by checking for it in your onCreate() method.

Note: If your searchable activity launches in single top mode (android:launchMode="singleTop"), also handle the ACTION_SEARCH intent in the onNewIntent() method. In single top mode, only one instance of your activity is created and subsequent calls to start your activity do not create a new activity on the stack. This launch mode is useful so users can perform searches from the same activity without creating a new activity instance every time.

Okay, the problem had to do with calling onSearchRequested() in onOptionsItemSelected(MenuItem item). That is redundant when I have a SearchView and should only be called on older platforms.

So, I created a separate menu item for devices under Honeycomb. It is removed at runtime for newer devices. The SearchView is removed at runtime for older devices.

See updated code below:

@SuppressLint("NewApi")
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    mMenu = menu;
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);



    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
        //remove old
        menu.removeItem(R.id.search_old);
        SearchManager searchManager =
                (SearchManager) getSystemService(Context.SEARCH_SERVICE);
        SearchView searchView =
                (SearchView) menu.findItem(R.id.search).getActionView();
        searchView.setSearchableInfo(
                searchManager.getSearchableInfo(getComponentName()));
        searchView.setIconifiedByDefault(false);
    } else{
        //remove new
        menu.removeItem(R.id.search);
    }


    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.search_old:
            onSearchRequested();
            return true;
        default:
            return false;
    }
}

@SuppressLint("NewApi")
@Override
public boolean onSearchRequested() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
        MenuItem mi = mMenu.findItem(R.id.search);
        if(mi.isActionViewExpanded()){
            mi.collapseActionView();
        } else{
            mi.expandActionView();
        }
    } else{
        //onOptionsItemSelected(mMenu.findItem(R.id.search));
    }
    return super.onSearchRequested();
}
