Ajouter Menu contextuel Icône dans Android

Question

J'ai un Listview avec un ContextMenu, mais quand je setIcon pour ContextMenu ressemble à ça ne fonctionne pas

public void onCreateContextMenu(ContextMenu menu , View v, 
        ContextMenuInfo menuInfo){

    super.onCreateContextMenu(menu, v, menuInfo);
    menu.add(0, DELETE_ID, 0, R.string.context_menu_favorite)
        .setIcon(android.R.drawable.btn_star);      
}

Answer 1

Les menus contextuels ne prennent pas en charge les icônes.

  

Remarque: les éléments du menu contextuel ne pas   icônes de soutien ou des touches de raccourci.

Answer 2

Cette bibliothèque vous permet d'avoir un menu contextuel (mis en oeuvre comme AlertDialog) avec des icônes en utilisant un menu standard XML.

Answer 3

Je l'ai fait de cette façon:

capture d'écran de référence:

Menu:

menu_patient_language.xml

<?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"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context=".activities.PatientSelectionActivity">

    <item
        android:id="@+id/menuEnglish"
        android:icon="@drawable/language_english"
        android:title="@string/english" />

    <item
        android:id="@+id/menuFrench"
        android:icon="@drawable/language_french"
        android:title="@string/french" />

</menu>

Style:

style.xml:

  <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->

        <item name="android:popupMenuStyle">@style/popupMenuStyle</item>

    </style>

  <!--- Language selection popup -->

    <style name="popupMenuStyle" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="android:textColor">@color/colorPrimary</item>
        <item name="android:itemBackground">@android:color/white</item>
    </style>

code Java:

 private void showPopup(View v) {

        Context wrapper = new ContextThemeWrapper(this, R.style.popupMenuStyle);
        PopupMenu mypopupmenu = new PopupMenu(wrapper, v);

        setForceShowIcon(mypopupmenu);
        MenuInflater inflater = mypopupmenu.getMenuInflater();
        inflater.inflate(R.menu.menu_patient_language, mypopupmenu.getMenu());
        mypopupmenu.show();
//        mypopupmenu.getMenu().getItem(0).setIcon(getResources().getDrawable(R.mipmap.ic_launcher));
        mypopupmenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
            @Override
            public boolean onMenuItemClick(MenuItem item) {
                txtPreferredLanguage.setText(item.getTitle().toString());
                switch (item.getItemId()) {
                    case R.id.menuEnglish:
                        // Your code goes here
                        break;

                    case R.id.menuFrench:
                        // Your code goes here
                        break;
                }
                return false;
            }
        });
    }

    private void setForceShowIcon(PopupMenu popupMenu) {
        try {
            Field[] mFields = popupMenu.getClass().getDeclaredFields();
            for (Field field : mFields) {
                if ("mPopup".equals(field.getName())) {
                    field.setAccessible(true);
                    Object menuPopupHelper = field.get(popupMenu);
                    Class<?> popupHelper = Class.forName(menuPopupHelper.getClass().getName());
                    Method mMethods = popupHelper.getMethod("setForceShowIcon", boolean.class);
                    mMethods.invoke(menuPopupHelper, true);
                    break;
                }
            }
        } catch (Throwable e) {
            e.printStackTrace();
        }
    }

Espérons que cela vous aiderait à vous.

Answer 4

Alors que l'API Android ne permet pas pour les icônes dans les menus contextuels vous pouvez voir de nombreux endroits où Android les utilise. Une longue pression de votre écran d'accueil est un bon exemple.

Je pris le temps de creuser à travers la source de lancement et AnyCut et a constaté que Google est en utilisant leur propre classe personnalisée qui étend une BaseAdapter avec leur propre mise en page personnalisée.

Je suis en mesure de copier leur classe et mise en page presque exactement et l'utiliser dans ma propre application pour accomplir. La classe si vous voulez rechercher il est appelé AddAdapter.java.

Amusez-vous!

Answer 5

vérifier .... un

@Override
    public void onCreateContextMenu(ContextMenu menu, View v,
   ContextMenuInfo menuInfo) {
  super.onCreateContextMenu(menu, v, menuInfo);
  menu.setHeaderTitle("Settings");
  menu.setHeaderIcon(R.drawable.ic_settings);
  menu.add(0, v.getId(), 0, "Action 1");
  menu.add(0, v.getId(), 0, "Action 2");
  menu.add(0, v.getId(), 0, "Action 3");
 }

 @Override
 public boolean onContextItemSelected(MenuItem item) {
  if (item.getTitle() == "Action 1") {
   Toast.makeText(this, "Action 1 invoked", Toast.LENGTH_SHORT).show();
  } else if (item.getTitle() == "Action 2") {
   Toast.makeText(this, "Action 2 invoked", Toast.LENGTH_SHORT).show();
  } else if (item.getTitle() == "Action 3") {
   Toast.makeText(this, "Action 3 invoked", Toast.LENGTH_SHORT).show();
  } else {
   return false;
  }
  return true;
 }

Answer 6

Alors que l'API ne prend pas en charge les icônes dans le menu contextuel, mais nous pouvons toujours truquer en gonflant un dialogue avec notre propre point de vue qui ressemble menu contextuel.

Copier-coller les fichiers suivants exactement faire le travail:

MainActivity.java

public class MainActivity extends Activity {

List<ContextMenuItem> contextMenuItems;
Dialog customDialog;

LayoutInflater inflater;
View child;
ListView listView;
ContextMenuAdapter adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    inflater = (LayoutInflater) this
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    child = inflater.inflate(R.layout.listview_context_menu, null);
    listView = (ListView) child.findViewById(R.id.listView_context_menu);

    contextMenuItems = new ArrayList<ContextMenuItem>();
    contextMenuItems.add(new ContextMenuItem(getResources().getDrawable(
            R.drawable.ic_launcher), "Facebook"));
    contextMenuItems.add(new ContextMenuItem(getResources().getDrawable(
            R.drawable.ic_launcher), "Scanner"));

    adapter = new ContextMenuAdapter(this,
            contextMenuItems);
    listView.setAdapter(adapter);

            listView.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View v,
                int position, long id) {
            customDialog.dismiss();
            if (position == 0)
                Toast.makeText(MainActivity.this, "00", Toast.LENGTH_SHORT)
                        .show();

            if (position == 1)
                Toast.makeText(MainActivity.this, "11", Toast.LENGTH_SHORT)
                        .show();

        }
    });

    customDialog = new Dialog(this);
    customDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    customDialog.setContentView(child);
    customDialog.show();
    }

}

ContextMenuItem.java

public class ContextMenuItem {

Drawable drawable;
String text;

public ContextMenuItem(Drawable drawable, String text) {
    super();
    this.drawable = drawable;
    this.text = text;
}

public Drawable getDrawable() {
    return drawable;
}

public void setDrawable(Drawable drawable) {
    this.drawable = drawable;
}

public String getText() {
    return text;
}

public void setText(String text) {
    this.text = text;
}

}

ContextMenuAdapter.java

public class ContextMenuAdapter extends BaseAdapter {
Context context;
List<ContextMenuItem> listContextMenuItems;
LayoutInflater inflater;

public ContextMenuAdapter(Context context,
        List<ContextMenuItem> listContextMenuItems) {
    super();
    this.context = context;
    this.listContextMenuItems = listContextMenuItems;
}

static class ViewHolder {
    protected ImageView imageView;
    protected TextView textView;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder viewHolder;
    if (convertView == null) {
        inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        viewHolder = new ViewHolder();
        convertView = inflater.inflate(R.layout.context_menu_item, parent,
                false);
        viewHolder.imageView = (ImageView) convertView
                .findViewById(R.id.imageView_menu);
        viewHolder.textView = (TextView) convertView
                .findViewById(R.id.textView_menu);
        convertView.setTag(viewHolder);
    } else {
        viewHolder = (ViewHolder) convertView.getTag();
    }

    viewHolder.imageView.setImageDrawable(listContextMenuItems
            .get(position).getDrawable());
    viewHolder.textView.setText(listContextMenuItems.get(position)
            .getText());
    return convertView;

}

@Override
public int getCount() {
    return listContextMenuItems.size();
}

@Override
public Object getItem(int position) {
    return null;
}

@Override
public long getItemId(int position) {
    return 0;
}

}
