Aggiunta di fragments da xml.

Nuovo esercizio sui fragment.
Creare due fragments in xml.

Cliccando direttamente su New -> Fragment ottengo sia il file xml sia quello java.

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#AAFFFF"
    tools:context=".primo">

    <!-- TODO: Update blank fragment layout -->
    <TextView
        android:id="@+id/testo1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="@string/hello_blank_fragment" />


</FrameLayout> 

(ci ho aggiunto uno sfondo celeste per distinguerlo)

public class primo extends Fragment {


    public primo() {
        // Required empty public constructor
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_primo, container, false);
    }

}

Adesso ottengo l'altro frammento:



Ecco, ho creato un frammento lasciando il nome di default, BlankFragment.
Vediamone il file xml e il file java.

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#FFAAAA"
    tools:context=".BlankFragment">

    <!-- TODO: Update blank fragment layout -->
    <TextView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="@string/hello_blank_fragment" />

</FrameLayout> 

Ci ho aggiunto uno sfondo rosso.

Ora devo riportare questi fragment sulla MainActivity: ho creato un altro video:



Ed ecco:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal"
    android:id="@+id/container"
    tools:context=".MainActivity">


    <fragment
        android:id="@+id/fragment"
        android:name="com.example.antonello.studiofragment.primo"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1" />

    <fragment
        android:id="@+id/fragment2"
        android:name="com.example.antonello.studiofragment.BlankFragment"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1" />
</LinearLayout> 

I due fragment hanno l'altezza impostata a wrap_content, per cui appaiono della stessa altezza delle textview compresevi dentro:

Ora vediamo il file java.

public class primo extends Fragment {


    public primo() {
        // Required empty public constructor
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_primo, container, false);
    }

}

Ecco, praticamente viene inflatato il codice xml del fragment all'interno del ViewGroup chiamato container.
Tutto qui.

YouTubePlayerView

E' il momento di fare e disfare Mandala su YouTubePlayerView.

public class MainActivity extends YouTubeBaseActivity {
    //DICHIARAZIONI DDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDDD
    YouTubePlayerView player;
    YouTubePlayer.OnInitializedListener onInitializedListener;
    Button button;
    String videoId = "4DTXAGGPFrw";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //INIZIALIZZAZIONI IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII
        player=(YouTubePlayerView)findViewById(R.id.youtubePlayer);
        button=(Button)findViewById(R.id.button);

        onInitializedListener = new OnInitializedListener() {
            @Override
            public void onInitializationSuccess(Provider provider, YouTubePlayer youTubePlayer, boolean b) {
                youTubePlayer.loadVideo(videoId);
            }

            @Override
            public void onInitializationFailure(Provider provider, YouTubeInitializationResult youTubeInitializationResult) {

            }
        };

        //IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII

        button.setOnClickListener(new View.OnClickListener(){

            @Override
            public void onClick(View view) {
                player.initialize(PlayerConfig.API_KEY,onInitializedListener);
            }
        });
    }
}

Questo codice l'ho scritto quasi di getto, e ha funzionato egregiamente...
