对于我的生活，我无法弄清楚，在查看文档和查看其他文章之间。当用户单击屏幕顶部的图像按钮时会发生这种情况

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

        android:textAppearance="?android:attr/textAppearanceLarge"

页面加载到 MainActivity.java 后调用

call = (ImageButton) findViewById(R.id.call);

    Picasso
            .with(this)
            .load(R.drawable.call_page1)
            .fit()
            .into(call);

    call.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            RelativeLayout appBar = (RelativeLayout)MainActivity.this.findViewById(R.id.bar);
            PopupMenu popup = new PopupMenu(MainActivity.this, v);
            MenuInflater inflater = popup.getMenuInflater();
            inflater.inflate(R.menu.contacts_menu, popup.getMenu());

            popup.setOnMenuItemClickListener(MainActivity.this);

            popup.show();
        }
    });

contacts_menu.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
android:icon="@drawable/call_page1">

<item
    android:id="@+id/sales_rep"
    android:title="@string/sales_rep">

</item>

<item
    android:id="@+id/rewards_cons"
    android:title="@string/rewards_cons">

</item>
</menu>

任何帮助将不胜感激。这应该是一件简单的事情，但由于某种原因给我带来了很多麻烦。我尝试将锚视图切换到图像按钮的父级，但这也不起作用。到目前为止，我有一种预感，这是布局的问题。

编辑：cox_background.xml 也是 res 文件夹中的可绘制对象。以防万一。

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">

<gradient
    android:startColor="#003469"
    android:centerColor="#003C72"
    android:endColor="#0585c8"
    android:angle="315"/>
</shape>

Edit2：cox_background.xml 位于 res/drawable 文件夹中。在运行 Marmallow 的 Google Nexus 5X 上进行测试。

Edit3：call_page1.png 位于 drawable-hdpi、drawable-mdpi、drawable-xhdpi、drawable-xxhdpi、drawable-xxxhdpi 文件夹中。 drawable-hdpi/call_page1.png

这些是透明图像。

【问题讨论】：

你有没有试过把android:background="@drawable/cox_background"这行代码去掉，测试一下是否仍然崩溃？
我认为这与drawable call_page1有关
我可以看看drawable吗？
Nolly：是的，我试过删除 android:background="@drawable/cox_background"。以前就是这样，我认为将背景设置为可绘制对象会有所帮助。

标签： java android xml popupmenu

【解决方案1】：

所以我在这里发现了问题。在styles.xml 中，我为整个应用程序定义了一个样式（我主要使用主题编辑器制作样式）。我为背景变量分配了一个drawable。直到现在我想当应用程序尝试使用菜单时，这并没有给我带来问题。

<style name="CoxTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@android:color/transparent</item>
    <!-- This cannot be a drawable. Must be a color-->
    <item name="android:colorBackground">@drawable/cox_background</item>
    <item name="android:textColorPrimary">@color/cox_text_primary</item>
    <item    name="android:textColorSecondary">@color/secondary_text_material_light</item>
    <item name="android:textColorPrimaryInverse">@color/primary_text_material_dark</item>
    <item name="android:screenOrientation">portrait</item>
    <item name="colorAccent">@color/cox_accent</item>
</style>
