android - ProGuard broke my Android code

Question

I added ProGuard to my Android project using default settings, and it broke my code.

On the first screen, I have a Button like this:

  <Button
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:onClick="onSaveButtonClick" />

And I have a method in the Class:

public void onSaveButtonClick(View view){
 // some code 
}

When ProGuard disabled, everything works just fine. When enabled, on clicking the button I get this error:

05-17 16:04:54.099: E/AndroidRuntime(1181): java.lang.IllegalStateException: Could not find a method onSaveButtonClick(View) in the activity class xxxx for onClick handler on view class android.widget.Button with id 'xxxxx'

Any ideas why this happened?

Proguard 正在将您的方法“onSaveButtonClick”更改为“a”。它不会更新您的 XML 文件，因此 Android 无法再找到它。您应该以编程方式设置您的点击处理程序（在视图上使用 setOnClickListener）或遵循 Keyser 发布的 SO 问题中链接的建议。
