android 呼入电话的监听（来电监听）

android 呼入电话的监听（来电监听）

 

 

需要权限：

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

 

方式一：通过广播接收来电

 

定义来电广播接收类

 

package com.zhouzijing.android.demo;

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

public class BroadcastReceiverMgr extends BroadcastReceiver {
	
	private final String TAG = MyBroadcastReceiver.TAG;

	@Override
	public void onReceive(Context context, Intent intent) {
		String action = intent.getAction();
		Log.i(TAG, "[Broadcast]"+action);
		
		//呼入电话
		if(action.equals(MyBroadcastReceiver.B_PHONE_STATE)){
			Log.i(TAG, "[Broadcast]PHONE_STATE");
			doReceivePhone(context,intent);
		}
	}
	
	/**
	 * 处理电话广播.
	 * @param context
	 * @param intent
	 */
	public void doReceivePhone(Context context, Intent intent) {
		String phoneNumber = intent.getStringExtra(
TelephonyManager.EXTRA_INCOMING_NUMBER);
		TelephonyManager telephony = 
(TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);
		int state = telephony.getCallState();
		switch(state){
		case TelephonyManager.CALL_STATE_RINGING:
			Log.i(TAG, "[Broadcast]等待接电话="+phoneNumber);
			break;
		case TelephonyManager.CALL_STATE_IDLE:
			Log.i(TAG, "[Broadcast]电话挂断="+phoneNumber);
			break;
		case TelephonyManager.CALL_STATE_OFFHOOK:
			Log.i(TAG, "[Broadcast]通话中="+phoneNumber);
			break;
		}
	}
}

定义Actitvity类

package com.zhouzijing.android.demo;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.view.View;

public class MyBroadcastReceiver extends Activity {
	public final static String TAG = "MyBroadcastReceiver";
	
	public final static String B_PHONE_STATE = 
TelephonyManager.ACTION_PHONE_STATE_CHANGED;
	
	private BroadcastReceiverMgr mBroadcastReceiver;
	
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.my_broadcast_receiver);
	}	

	//按钮1-注册广播
	public void registerIt(View v) {
		Log.i(TAG, "registerIt");
		mBroadcastReceiver = new BroadcastReceiverMgr();
		IntentFilter intentFilter = new IntentFilter();
		intentFilter.addAction(B_PHONE_STATE);
		intentFilter.setPriority(Integer.MAX_VALUE);
		registerReceiver(mBroadcastReceiver, intentFilter);
	}
	
	//按钮2-撤销广播
	public void unregisterIt(View v) {
		Log.i(TAG, "unregisterIt");
		unregisterReceiver(mBroadcastReceiver);
	}
	
}

 

 

方式二：通过监听器来实现

 

package com.zhouzijing.android.demo;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.view.View;

public class MyBroadcastReceiver extends Activity {
	public final static String TAG = "MyBroadcastReceiver";
	
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.my_broadcast_receiver);
	}
	
	/**
	 * 按钮-监听电话
	 * @param v
	 */
	public void createPhoneListener(View v) {
		TelephonyManager telephony = (TelephonyManager)getSystemService(
Context.TELEPHONY_SERVICE);
		telephony.listen(new OnePhoneStateListener(),
PhoneStateListener.LISTEN_CALL_STATE);
	}
	
	/**
	 * 电话状态监听.
	 * @author stephen
	 *
	 */
	class OnePhoneStateListener extends PhoneStateListener{
		@Override
		public void onCallStateChanged(int state, String incomingNumber) {
			Log.i(TAG, "[Listener]电话号码:"+incomingNumber);
			switch(state){
			case TelephonyManager.CALL_STATE_RINGING:
				Log.i(TAG, "[Listener]等待接电话:"+incomingNumber);
				break;
			case TelephonyManager.CALL_STATE_IDLE:
				Log.i(TAG, "[Listener]电话挂断:"+incomingNumber);
				break;
			case TelephonyManager.CALL_STATE_OFFHOOK:
				Log.i(TAG, "[Listener]通话中:"+incomingNumber);
				break;
			}
			super.onCallStateChanged(state, incomingNumber);
		}
	}
