我的res/drawable-hdpi/delete.png
中有.png图片我想将其作为图标添加到我的菜单item
。
我用过:
delete.xml
<bitmap
xmlns:android="http://schemas.android.com/apk/res/android"
android:src="@drawable/deletebutton">
</bitmap>
菜单 activity_main.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="@+id/create"
android:showAsAction="always"
android:title="@string/createTask"/>
<item
android:id="@+id/delete"
android:showAsAction="always"
android:icon="@drawable/delete"
android:title="@string/deleteTask" />
</menu>
但它不起作用。
我删除了xml文件并尝试直接加载图像,这里是日志文件。

答案 0 :(得分:12)
首先,你真的不需要delete.xml
。
<item
android:id="@+id/delete"
android:showAsAction="always"
android:icon="@drawable/deletebutton"
android:title="@string
/>
而且我认为你在这里有问题:
android:title="@string
在这里,你缺少右撇号和价值。如果您不想在 MenuItem 中显示标题,只需删除此属性。
java.lang.StackOverflowError
你在loadDrawable()中有 SO
,这意味着 Drawable 太大而无法加载(你的堆栈已完全填满)。尝试使用另一个(较小的)或修剪实际的一个。并确保在所有可绘制文件夹中都有图像。

它已经过期,但我会给出一个答案,仅供其他人参考,你可以像程序化那样做进一步的样式:
public class MyClass {
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
// Do your other stuff here
MenuItem item = menu.getItem(0);
if (item.getItemId() == R.id.action_example) {
ImageView imageView = new ImageView(getActivity());
imageView.setMaxHeight(18);
imageView.setMaxWidth(18);
imageView.setImageResource(R.drawable.barchart32);
item.setActionView(imageView);
}
}
}
答案 2 :(得分:0)
看看这个:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/open" android:icon="@drawable/openicon"
android:title="Open the file" />
<item
android:id="@+id/save"
android:icon="@drawable/saveicon"
android:title="Save the file" />
</menu>
无需设置位图文件,只需单独使用上面的行。希望这会帮助你。
按照本教程Menus in Android

android:background="@drawable/ic_play" />
就是我在做什么,
