Question

我按照以下方式创建了弹出菜单：

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.shehabic.droppy_samples.MainActivity">
<group android:enabled="true">
    <item
        android:id="@+id/itemUserProfile"
        android:icon="@drawable/popup_profile"
        android:title="User Name"
        >


    </item>

    <item
        android:id="@+id/itemProfileSetting"
        android:icon="@drawable/popup_setting"
        android:title="Settings"
        />
</group>
<group android:enabled="true">
    <item
        android:id="@+id/itemFAQ"
        android:icon="@drawable/popup_faq"
        android:title="FAQ" />

    <item
        android:id="@+id/itemContactUs"
        android:icon="@drawable/popup_contact_us"
        android:title="Contact Us" />
</group>


<group android:enabled="true">
    <item
        android:id="@+id/itemAboutUs"
        android:icon="@drawable/popup_about_us"
        android:title="About Us" />

</group>

现在，在第一项中，我想显示一个在注册时捕获的图像。我将我的Image转换为base 64并存储在shared pref中。以及我做过的主要活动：

if(SharedPref.getSharedPref().getValue(getApplicationContext(),"name").length() >0){
        user_name =SharedPref.getSharedPref().getValue(getApplicationContext(),"name");
    }

    if(SharedPref.getSharedPref().getValue(getApplicationContext(),"profile_img_encoded").length() > 0){
        String encoded =SharedPref.getSharedPref().getValue(getApplicationContext(),"profile_img_encoded");
        byte[] imageAsBytes = Base64.decode(encoded.getBytes(),Base64.DEFAULT);
        Bitmap bitmap= BitmapFactory.decodeByteArray(imageAsBytes, 0, imageAsBytes.length);
        user_img = new BitmapDrawable(getResources(), bitmap);

    }

但无法将其设置为菜单图标，因为user_img属于android.graphics.drawable.Drawable。有什么方法可以将我的图像显示为菜单图标，或者任何方式，以便我可以生成ListView样式弹出菜单。

Answer 1

Private Menu menu

     @Override
        public boolean onCreateOptionsMenu(Menu menu) {

            // Inflate the menu; this adds items to the action bar if it is present.
            getMenuInflater().inflate(R.menu.main, menu);

            this.menu = menu;
            ImageView imageView = new ImageView(getActivity());
            imageView.setMinimumHeight(128);
            imageView.setMinimumWidth(128);
            imageView.setImageDrawable(yourDrawable);
            MenuItem item = this.menu.getItem(0);
            item.setActionView(imageView);
            return true;
        }

第二个Approch：

   @Override
 public boolean onPrepareOptionsMenu(Menu menu) {

    MenuItem settingsItem = menu.findItem(R.id.action_settings);
    // set your desired icon here based on a flag if you like
    settingsItem.setIcon(getResources().getDrawable(R.drawable.ic_launcher)); 

    return super.onPrepareOptionsMenu(menu);
 }

如果你想要带有图标的弹出菜单：

btnExpand.setOnClickListener(new View.OnClickListener()
{
                @Override
                public void onClick(View v) {
                  PopupMenu popup = new PopupMenu(btnExpand.getContext(), itemView);
                    popup.setOnMenuItemClickListener(newPopupMenu.OnMenuItemClickListener(){

                        @Override
                        public boolean onMenuItemClick(MenuItem item) {
                            switch (item.getItemId()) {
                                case R.id.action_Delete:                                    
                                    return true;
                                case R.id.action_share:                                  
                                    return true;
                                default:
                                    return false;
                            }
                        }
                    });
           // here you can inflate your view
                    popup.inflate(R.menu.second_contect);
                    //popup.setGravity(Gravity.TOP);
// write this if you want menu with icons
                    try {
                        Field mFieldPopup=popup.getClass().getDeclaredField("mPopup");
                        mFieldPopup.setAccessible(true);
                        MenuPopupHelper mPopup = (MenuPopupHelper) mFieldPopup.get(popup);
                        mPopup.setForceShowIcon(true);
                    } catch (Exception e) {

                    }
                    popup.show();
                }
            });
