我实际上想覆盖默认呼叫屏幕并处理我的活动中的所有内容。我面临的问题是如何获取来电者号码，如果它是来自 Telecom.Call 对象的存储在我手机中的联系人，因为这是 InCallService onCallAdded 方法中唯一可用的对象。

提前感谢您的帮助。

public MyConnectionService() {
}

@Override
public void onCallAdded(Call call) {
    super.onCallAdded(call);
    Log.d("Call","new call Added");
    CallActivity.call=call;
    startActivity(new Intent(this,CallActivity.class));
}

@Override
public void onCallRemoved(Call call) {
    super.onCallRemoved(call);
    Log.d("Call","Call Removed");
}

这是接受和拒绝呼叫的活动。现在屏幕上只显示 2 个按钮来接听和拒绝来电，它工作正常，我还需要在屏幕上显示联系方式。

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_call);

    name=findViewById(R.id.name);

    screenLock = ((PowerManager)getSystemService(POWER_SERVICE)).newWakeLock(
            PowerManager.SCREEN_BRIGHT_WAKE_LOCK | PowerManager.ACQUIRE_CAUSES_WAKEUP, "TAG");
    screenLock.acquire();

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON|
            WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD|
            WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED|
            WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);

    name.setText(call.getRemainingPostDialSequence());  //call.getDetails().getCallerDisplayName()

    call.registerCallback(new Call.Callback() {
        @Override
        public void onCallDestroyed(Call call) {
            super.onCallDestroyed(call);
            CallActivity.this.finish();
        }

        @Override
        public void onDetailsChanged(Call call, Call.Details details) {
            super.onDetailsChanged(call, details);
            Log.d("details",call.getRemainingPostDialSequence()+":"+details.getCallerDisplayName());
        }
    });

}

你有两个选择。

  1. 要求用户将您的应用设置为默认电话应用（基本上您的应用将是您需要实现的新InCallService/ ），请参阅： https ://developer.android.com/reference/android/telecom/InCallServiceInCallUI

  2. 实现一个PhoneStateListener以检测电话状态变化（空闲/响铃/摘机）并在适当时在默认 InCallUI 上方显示您的 UI，请参阅：https ://developer.android.com/reference/android/telephony/PhoneStateListener和Add PhoneStateListener
