C'è un modo semplice per creare un frammento di pulsante di azione?

Question

pulsante Azione è questo:

penso che il quadro dovrebbe fornire Frammento facile da usare in cui lo sviluppatore fornisce solo titolo, icona, immagine di sfondo e ascoltatore. Non l'ho trovato nei documenti, lo sai?

Answer 1

ho finito per scrivere io stesso in base alle design guidelines:

ActionFragment.java

public class ActionFragment extends Fragment implements View.OnClickListener { 

    private static Listener mListener; 
    private CircledImageView vIcon; 
    private TextView vLabel; 

    public static ActionFragment create(int iconResId, int labelResId, Listener listener) { 
     mListener = listener; 
     ActionFragment fragment = new ActionFragment(); 
     Bundle args = new Bundle(); 
     args.putInt("ICON", iconResId); 
     args.putInt("LABEL", labelResId); 
     fragment.setArguments(args); 
     return fragment; 
    } 

    @Override 
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
     return inflater.inflate(R.layout.fragment_action, container, false); 
    } 

    @Override 
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) { 
     super.onViewCreated(view, savedInstanceState); 
     vIcon = (CircledImageView) view.findViewById(R.id.icon); 
     vLabel = (TextView) view.findViewById(R.id.label); 
     vIcon.setImageResource(getArguments().getInt("ICON")); 
     vLabel.setText(getArguments().getInt("LABEL")); 
     view.setOnClickListener(this); 
    } 

    @Override 
    public void onClick(View v) { 
     mListener.onActionPerformed(); 
    } 

    public interface Listener { 
     public void onActionPerformed(); 
    } 
} 

layout/fragment_action.xml

<?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:orientation="vertical" 
       android:paddingLeft="16dp" 
       android:paddingRight="16dp" 
       android:paddingTop="24dp" 
       android:paddingBottom="12dp" 
       android:layout_width="match_parent" 
       android:layout_height="match_parent"> 

    <android.support.wearable.view.CircledImageView 
     android:id="@+id/icon" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_gravity="center" 
     tools:src="@drawable/ic_full_cancel" 
     app:circle_color="@color/action_button" 
     app:circle_radius="52dp" 
     app:circle_border_width="0dp"/> 

    <TextView 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:gravity="center" 
     tools:text="Cancel" 
     android:id="@+id/label" 
     android:fontFamily="sans-serif-condensed-light" 
     android:textSize="20sp" 
     android:textColor="@color/white"/> 

</LinearLayout> 

colore/action_button.xml

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item android:color="#2878ff" android:state_pressed="false" /> 
    <item android:color="#2955C5" android:state_pressed="true" /> 
</selector> 

Esempio di utilizzo (ad es. in FragmentGridPagerAdapter)

ActionFragment.create(R.drawable.ic_full_open_on_phone, R.string.open_on_phone, new ActionFragment.Listener() { 
        @Override 
        public void onActionPerformed() { 

        } 
       });
