Android 如何将我们自己的背景图像设置为xml格式的facebook登录按钮？

是否可以为Facebook登录按钮设置我们自己的xml背景图像

我的项目中的xmlc（即FBDemo）

我将自己的背景信息传递到xml中的Facebbok loginbutton的xml中

但这给了我如下的运行时错误

08-07 06:41:59.492: E/AndroidRuntime(1731): Caused by: java.lang.NumberFormatException: Invalid int: "res/drawable-hdpi/login_with_fb.png"

我认为发生此错误的原因是，带有_fb.png图像的登录_位于FBDemo中，FacebookSDK项目无法找到带有_fb.png图像的可绘制图像登录_

我知道另一种方法，只是在活动中设置背景图像，但我想在xml中设置

有什么解决方案吗？？？

您只想更改FB登录按钮的背景图像或文本吗

用于更改其背景图像（非运行时）

1.将图像复制到FB SDK的drawable mdpi文件夹中

2.在else模式下写入此行（非编辑模式）

3.在代码行下方添加注释和注释

    this.setCompoundDrawablesWithIntrinsicBounds(R.drawable.com_facebook_inverse_icon, 0, 0, 0);

4.1在xml中

<com.facebook.widget.LoginButton
android:id="@+id/authButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@+id/btn_login"
android:layout_centerHorizontal="true"
android:layout_marginTop="15dp"
facebook:background_image="@drawable/login_with_fb"
facebook:confirm_logout="false"
facebook:fetch_user_info="true"
android:textStyle="bold"
/>

您应该将其更改为默认按钮并在onButtonClick中调用facebook。

请在您的facebook SDK中更改以下代码：转到com.facebook.widget.LoginButton.java
