我试图在菜单操作附近显示图标,但出于某种原因,当我使用AppCompatActivity / AppCompat主题时,我无法显示它们。
我只收到文字。
我尝试了以下内容:
@Override
public boolean onMenuOpened(int featureId, Menu menu)
{
if(featureId == Window.FEATURE_ACTION_BAR && menu != null)
{
if(menu.getClass().getSimpleName().equals("MenuBuilder"))
{
try
{
Method m = menu.getClass().getDeclaredMethod("setOptionalIconsVisible", Boolean.TYPE);
m.setAccessible(true);
m.invoke(menu, true);
}
catch(NoSuchMethodException e)
{
Log.e("Menu:", "onMenuOpened", e);
}
catch(Exception e)
{
throw new RuntimeException(e);
}
}
}
return super.onMenuOpened(featureId, menu);
}
仍然相同:(
以下是菜单ITEMS(menu.xml):

工具栏仅在Navigation Drawer.xml中创建
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"

toolbar.xml包含以下内容:

这是我正在使用的Style主题:

这里有什么问题?如何显示图标?

对于AppCompatActivity,您可以将此检查放在onPrepareOptionsPanel()上。
@Override
protected boolean onPrepareOptionsPanel(View view, Menu menu) {
if (menu != null) {
if (menu.getClass().getSimpleName().equals("MenuBuilder")) {
try {
Method m = menu.getClass().getDeclaredMethod(
"setOptionalIconsVisible", Boolean.TYPE);
m.setAccessible(true);
m.invoke(menu, true);
} catch (Exception e) {
Log.e(getClass().getSimpleName(), "onMenuOpened...unable to set icons for overflow menu", e);
}
}
}
return super.onPrepareOptionsPanel(view, menu);
}

谢谢! 另外,将代码放在onPrepareOptionsMenu(菜单菜单)中即可, 像这样
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
if (menu != null) {
if (menu.getClass().getSimpleName().equals("MenuBuilder")) {
try {
Method m = menu.getClass().getDeclaredMethod(
"setOptionalIconsVisible", Boolean.TYPE);
m.setAccessible(true);
m.invoke(menu, true);
} catch (Exception e) {
Log.e(getClass().getSimpleName(), "onMenuOpened...unable to set icons for overflow menu", e);
}
}
}
return super.onPrepareOptionsMenu(menu);
}
