I understood that it is impossible to customize or to change the exiting income screen, Is it right? if the answer is no than how? if the answer is yes than I want to know how to add screen above the income call screen?

也许，如果你的应用程序句柄的的ACTION_ANSWER意图，则可以显示任何画面你喜欢。我不认为这将可以自定义现有的屏幕，只是用自己的替换它。

Perhaps if your app handles the ACTION_ANSWER intent, you could display whatever screen you like. I don't think this will enable you to customize the existing screen, just replace it with your own.

有关您的应用程序来处理，你必须意图过滤器添加到应用程序清单文件的意图。这在 Intent类文档。这里是你如何能处理ACTION_ANSWER意图快速出样：

For your app to handle intents you have to add intent filters to the app manifest file. This is fully described in the Intent class documentation. Here is a quick sample on how you could handle the ACTION_ANSWER intent:

     <activity class=".MyCustomCallActivity"
               android:label="@string/mycustomcall_title">
         <intent-filter>
             <action android:name="android.intent.action.ANSWER" />
         </intent-filter>

         ...
     </activity>
