我该如何接听电话并挂断电话？

我有代码应该接听电话并在有人拨打电话时立即挂断电话。 当来自不同的电话的呼叫时，我没有错误并且没有强制关闭。 问题是它没有做它应该做的事情。

这是广播公司：

package com.QuickCallBlocking; import java.lang.reflect.Method; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.os.Bundle; import android.telephony.TelephonyManager; import com.android.internal.telephony.ITelephony; public abstract class CallBlock extends BroadcastReceiver { private Context context; private ITelephony telephonyService; /** Called when the activity is first created. */ public void getTeleService() { TelephonyManager tm = (TelephonyManager) context getSystemService(Context.TELEPHONY_SERVICE); try { // Java reflection to gain access to TelephonyManager's // ITelephony getter Class c = Class.forName(tm.getClass().getName()); Method m = c.getDeclaredMethod("getITelephony"); m.setAccessible(true); com.android.internal.telephony.ITelephony telephonyService = (ITelephony) m.invoke(tm); } catch (Exception e) { e.printStackTrace(); } telephonyService.endCall(); } String[] blockedNumbers = {"[phone]")}; String incommingNumber; @Override public void onReceive(Context context, Intent intent) { Bundle b = intent.getExtras(); incommingNumber = b.getString(TelephonyManager.EXTRA_INCOMING_NUMBER); // Additional Step // Check whether this number matches with your defined Block List // If yes, Reject the Call } }

Answer 1

我不认为你想在getTeleService()做telephonyService.endCall() getTeleService() 。 您可能希望在onReceive方法中调用它。

我不确定您是要拒绝所有来电还是仅拒绝来自某些号码的电话。 如果您尝试仅拒绝某些号码，看起来您没有任何代码可以在此处检索阻止号码后检查来电号码：

 public void onReceive(Context context, Intent intent) { Bundle b = intent.getExtras(); incommingNumber = b.getString(TelephonyManager.EXTRA_INCOMING_NUMBER); --->// Additional Step <--- --->// Check whether this number matches with your defined Block List <--- --->// If yes, Reject the Call <--- } 

如果要检查号码并拒绝来自被阻止号码的呼叫，您可以尝试将其更改为以下内容：

 public void onReceive(Context context, Intent intent) { Bundle b = intent.getExtras(); incommingNumber = b.getString(TelephonyManager.EXTRA_INCOMING_NUMBER); // Additional Step // Check whether this number matches with your defined Block List // If yes, Reject the Call for (int i=0; i 

或者如果你只是想拒绝所有的电话，它甚至更简单：

 public void onReceive(Context context, Intent intent) { telephonyService.endCall(); } 

Answer 2

是的，人们不能只使用

因为它是由系统保留的，所以对于应答呼叫，我们使用像这里的蓝牙技巧，并且为了拒绝呼叫，我们仍然可以使用TelephonyManager的endCall（）; function。 它实际上没有这样的许可。 别忘了添加

虽然！ 干杯…

Answer 3

将以下代码添加到AndroidManifest.xml

    (add it after READ_PHONE_STATE and before MODIFY_PHONE_STATE")  

并将其用于EndCall：

 private void endCall() { Class c = TelephonyManager.class; Method getITelephonyMethod = null; try { getITelephonyMethod = c.getDeclaredMethod("getITelephony",(Class[]) null); getITelephonyMethod.setAccessible(true); ITelephony iTelephony = (ITelephony) getITelephonyMethod.invoke(tm, (Object[]) null); iTelephony.endCall(); } catch (Exception e) { } }
