android - Android 上带图标的弹出菜单

Question

我的菜单 xml 代码menu.xml:

<?xml version="1.0" encoding="utf-8"?><menu xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Single menu item 
     Set id, icon and Title for each menu item
-->

 <item android:id="@+id/back"
      android:icon="@drawable/back1"
        android:showAsAction="never"
      android:title="Back" />

<item android:id="@+id/My_Profile"
      android:icon="@drawable/myprofile"
       android:showAsAction="never"
      android:title="My Profile" />

<item android:id="@+id/Job_Alert"
      android:icon="@drawable/jobalert4"
       android:showAsAction="never"
      android:title="Job Alert !" />

<item android:id="@+id/saved_job"
      android:icon="@drawable/jobapplied"
      android:title="Saved Jobs"
       />


<item android:id="@+id/Logout"
      android:icon="@drawable/logout"
      android:title="Logout" /> 
</menu>

我这样调用菜单xml

     PopupMenu popup = new PopupMenu(getBaseContext(), v);
 popup.getMenuInflater().inflate(R.menu.menu,  popup.getMenu());
     popup.show();

但它不显示图标。

如何在弹出菜单上设置图标？

Answer 1

您可以使用 MenuBuilder 和 MenuPopupHelper 创建带图标的弹出菜单。

MenuBuilder menuBuilder =new MenuBuilder(this);
MenuInflater inflater = new MenuInflater(this);
inflater.inflate(R.menu.menu, menuBuilder);
MenuPopupHelper optionsMenu = new MenuPopupHelper(this, menuBuilder, view);
optionsMenu.setForceShowIcon(true);

// Set Item Click Listener
menuBuilder.setCallback(new MenuBuilder.Callback() {
    @Override
    public boolean onMenuItemSelected(MenuBuilder menu, MenuItem item) {
        switch (item.getItemId()) {
            case R.id.opt1: // Handle option1 Click
                return true;
            case R.id.opt2: // Handle option2 Click
                return true;
            default:
                return false;
        }
    }

    @Override
    public void onMenuModeChange(MenuBuilder menu) {}
});

optionsMenu.show();

菜单.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/opt1"
        android:icon="@mipmap/ic_launcher"
        android:title="option 1" />
    <item
        android:id="@+id/opt2"
        android:icon="@mipmap/ic_launcher"
        android:title="option 2" />
</menu>
