推荐答案

您需要创建一个 BroadCastReceiver 将在操作中调用： NEW_OUTGOING_CALL

You need to create a BroadCastReceiver that will be called on the action : NEW_OUTGOING_CALL

Java类：

public class CallReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(final Context context, final Intent intent) {
        if (intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){
            setResultData(null);
            abortBroadcast(); // cancel the call
        }
    }
}

清单声明

不要忘记添加运行许可

<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" /> 

<receiver android:name=".CallReceiver" >
    <intent-filter android:priority="2147483647" >
        <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
    </intent-filter>
</receiver>
