如何在动态壁纸的设置屏幕中放置 admob 广告视图? [英] How do I put an admob adview in the settings screen for a live wallpaper?

问题描述

我已经在设置屏幕中看到马里奥动态壁纸使用了 admob 广告，但我自己一直无法做到.如果我像使用普通布局一样将 adview 放入 settings.xml 中，则会出现类转换异常.

I've seen the Mario live wallpaper uses admob ads in the settings screen, but I haven't been able to do it myself. If I put the adview into the settings.xml like you would with a normal layout I get a class cast exception.

这是 mario 动态壁纸的屏幕截图，用于说明我正在尝试做什么.

Here's a screenshot of the mario live wallpaper to illustrate what I'm trying to do.

推荐答案

这里有一个更简单的解决方案:创建一个新的首选项类型来显示单个广告.然后，您可以在 xml 定义中包含该首选项类型，以便您的首选项显示一个或多个广告.

Here's a simpler solution: Create a new preference type that displays a single ad. You can then include that preference type in the xml definition for your preferences to display one or more ads.

自定义偏好类:

public class AdmobPreference extends Preference
{

    public AdmobPreference(Context context) {
        super(context, null);
    }

    public AdmobPreference(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    protected View onCreateView(ViewGroup parent) {
            //override here to return the admob ad instead of a regular preference display
        LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        return inflater.inflate(R.layout.admob_preference, null);
    }

}

AdmobPreference 的 XML 布局:

XML Layout for AdmobPreference:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:myapp="http://schemas.android.com/apk/res/<YOUR PACKAGE>"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
>

    <com.google.ads.AdView android:id="@+id/ad" android:layout_width="fill_parent"
        android:layout_height="wrap_content" myapp:backgroundColor="#000000" myapp:primaryTextColor="#FFFFFF"
        myapp:secondaryTextColor="#CCCCCC" />
</LinearLayout>

然后您只需在首选项 xml 定义中添加类似的内容:

And then you just add something like this into your preferences xml definition:

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

    <YOUR PACKAGE NAME.AdmobPreference android:key="ad" />

    ... other preferences ...
</PreferenceScreen>
