Question

我尝试了很多解决方案，我需要检测何时接听或拒绝接听电话，任何建议都会对我有所帮助。我试图使用布尔值检测。请帮我解决一下。

我的代码：

public class CallerToActivity extends BroadcastReceiver {
    // static boolean wasRinging;
    static boolean finish = false;
    static Context mcontext;

    public void onReceive(Context context, Intent intent) {

        PhoneStateChangeListener pscl = new PhoneStateChangeListener();
        TelephonyManager tm = (TelephonyManager) context
                .getSystemService(Context.TELEPHONY_SERVICE);
        tm.listen(pscl, PhoneStateListener.LISTEN_CALL_STATE);
        mcontext=context;
    }

    private static class PhoneStateChangeListener extends PhoneStateListener {
        static boolean wasRinging;

        @Override
        public void onCallStateChanged(int state, String incomingNumber) {
            switch (state) {
            case TelephonyManager.CALL_STATE_RINGING:
                Log.i("Status", "RINGING");
                wasRinging = true;
                break;
            case TelephonyManager.CALL_STATE_OFFHOOK:
                Log.i("Status", "OFFHOOK");

                if (wasRinging == false) {
                    // Start your new activity

                } else {
                    // Cancel your old activity
                }

                // this should be the last piece of code before the break
                wasRinging = true;
                break;
            case TelephonyManager.CALL_STATE_IDLE:
                Log.i("Status", "IDLE");
                // this should be the last piece of code before the break
                wasRinging = false;
                break;
            }
        }
    }
}

以下是我用来做这件事的事情：

我的电话呼叫检测器

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

<!--This part is inside the application-->
    <receiver android:name=".CallReceiver" >
        <intent-filter>
            <action android:name="android.intent.action.PHONE_STATE" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        </intent-filter>
    </receiver>

然后使用它，只需从中派生一个类并实现一些简单的函数，无论你关心哪种调用类型：

package com.xyz.android.reusable.receivers;

import java.util.Date;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.TelephonyManager;

public abstract class PhonecallReceiver extends BroadcastReceiver {

    //The receiver will be recreated whenever android feels like it.  We need a static variable to remember data between instantiations

    private static int lastState = TelephonyManager.CALL_STATE_IDLE;
    private static Date callStartTime;
    private static boolean isIncoming;
    private static String savedNumber;  //because the passed incoming is only valid in ringing


    @Override
    public void onReceive(Context context, Intent intent) {

        //We listen to two intents.  The new outgoing call only tells us of an outgoing call.  We use it to get the number.
        if (intent.getAction().equals("android.intent.action.NEW_OUTGOING_CALL")) {
            savedNumber = intent.getExtras().getString("android.intent.extra.PHONE_NUMBER");
        }
        else{
            String stateStr = intent.getExtras().getString(TelephonyManager.EXTRA_STATE);
            String number = intent.getExtras().getString(TelephonyManager.EXTRA_INCOMING_NUMBER);
            int state = 0;
            if(stateStr.equals(TelephonyManager.EXTRA_STATE_IDLE)){
                state = TelephonyManager.CALL_STATE_IDLE;
            }
