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。问题在于它没有做它应该做的事情。
这是播音员：
package com.QuickCallBlocking;
import java.lang.reflect.Method;

import android.content.Context;
import android.content.Intent;
import android.os.Bundle;

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 = {"+911234567")};
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
}
}

我认为你不想在telephonyService.endCall()中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来电。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 <---
}
如果您想检查号码并拒绝来自被屏蔽号码的来电，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<blockedNumbers.length; i++) {
if (incommingNumber.equals(blockedNumbers[i])) {
telephonyService.endCall();
break;
}
}
}
或者，如果您只是想拒绝所有来电，那就更简单了：
public void onReceive(Context context, Intent intent) {
telephonyService.endCall();
}

是的，不能只使用
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE"/>
因为它是由系统保留的，所以对于接听电话，我们使用像here这样的蓝牙技巧，为了拒绝来电，我们仍然可以使用TelephonyManager的endCall（）;功能。它实际上没有这样的许可。别忘了添加
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<uses-permission android:name="android.permission.CALL_PHONE"/>
但！干杯...
答案 2 :(得分：0)
将以下代码添加到AndroidManifest.xml
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.CALL_PHONE"/> (add it after READ_PHONE_STATE and before MODIFY_PHONE_STATE")
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE" />
并将其用于EndCall：
private void endCall()
{
Class<TelephonyManager> 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) {
}
}
