最近因为项目的原因需要实现一个来电监听，且生成一个悬浮窗口提示相关信息（具体什么信息不方便透露哈）。

现把我的思路及实现方法大致说下哈。

想要监听来电首先需要要manifest中申明"android.permission.READ_PHONE_STATE"权限

Xml代码


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

还需要注册来电监听，目前我的处理方式是接收开机广播，然后在接收到广播后注册来电监听。接收开机广播需要有“android.permission.RECEIVE_BOOT_COMPLETED”权限，manifest中申明如下

Java代码


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

然后注册广播接收类

Xml代码


<receiver android:name=".PhoneBootReceiver">

<intent-filter>

<action android:name="android.intent.action.BOOT_COMPLETED" />

</intent-filter>

</receiver>

PhoneBootReceiver中注册监听来电，首先得获取系统服务“TELEPHONY_SERVICE”

Java代码


TelephonyManager telM = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);

然后添加监听

Java代码


telM.listen(new TelListener(context), PhoneStateListener.LISTEN_CALL_STATE);

TelListener是自己定义的电话状态监听类，继承自PhoneStateListener，监听来电只需要实现onCallStateChanged(int state, String incomingNumber)方法。

咳咳...标题上说了弹出悬浮窗口，其实悬浮窗口就是在WindowManager中添加一个View，这个功能我也是在TelListener实现的。要想实现悬浮窗口，首先得有“android.permission.SYSTEM_ALERT_WINDOW”的权限，在manifest中申明如下：

Xml代码


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

WindowManager需要通过context.getApplicationContext().getSystemService(Context.WINDOW_SERVICE);

来获取。

先把TelListener源码放出来，再详解

Xml代码


public class TelListener extends PhoneStateListener {

private Context context;

private WindowManager wm;

private TextView tv;

public TelListener(Context context){

this.context = context;

}

@Override

public void onCallStateChanged(int state, String incomingNumber) {

// TODO Auto-generated method stub

super.onCallStateChanged(state, incomingNumber);

if(state == TelephonyManager.CALL_STATE_RINGING){

wm = (WindowManager)context.getApplicationContext().getSystemService(Context.WINDOW_SERVICE);

WindowManager.LayoutParams params = new WindowManager.LayoutParams();

params.type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY;

params.flags = WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;

params.width = WindowManager.LayoutParams.WRAP_CONTENT;

params.height = WindowManager.LayoutParams.WRAP_CONTENT;

<span style="white-space: pre;"> </span>params.format = PixelFormat.RGBA_8888;

tv = new TextView(context);

tv.setText("这是悬浮窗口，来电号码：" + incomingNumber);

wm.addView(tv, params);

}else if(state == TelephonyManager.CALL_STATE_IDLE){

if(wm != null){

wm.removeView(tv);

}

}

}

}

state = TelephonyManager.CALL_STATE_RINGING表示有新的来电，state = TelephonyManager.CALL_STATE_IDLE表示电话中断（可能理解不是很准确，电话挂断的时候state会和TelephonyManager.CALL_STATE_IDLE相等）

定义窗口布局

Java代码


WindowManager.LayoutParams params = new WindowManager.LayoutParams();

设置窗口类型在所有窗口之上

Java代码


params.type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY;

别忘了

Java代码


params.flags = WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;

如果没有这句话的话，在生成悬浮窗口后，悬浮窗口后的界面上东西都不能点。这句话的目的是让悬浮窗口失去焦点。

背景透明

Java代码


params.format = PixelFormat.RGBA_8888;

本例中悬浮窗口只是显示一个TextView其内容为“这是悬浮窗口，来电号码：xxxxxx”，最后将TextView添加到窗体中

Java代码


wm.addView(tv, params);

在电话中断后将TextView移除，否则会一直显示的...

Java代码


wm.removeView(tv);

啦..本文就到这儿了...

“啥？要可移动的？”

要想可以拖动的话,那给TextView添加setOnTouchListener，实现OnTouchListener的onTouchListener方法。

对了，别忘了将

Java代码


params.type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY;

修改为

Java代码


params.type = WindowManager.LayoutParams.TYPE_PHONE;

因为TYPE_SYSTEM_OVERLAY的话是TextView获取不到输入焦点，也就没法拖动了哈。

android 呼入电话的监听（来电监听）

需要权限：

Xml代码



<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

Java代码



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

Java代码



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

Java代码



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);

}

}

}

android 呼出电话的监听（去电监听）

权限：

Xml代码



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

通过接收呼出电话的广播来实现

定义广播类

Java代码



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);

//呼出电话

if(action.equals(MyBroadcastReceiver.B_ACTION_NEW_OUTGOING_CALL)){

String outPhoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);

Log.i(TAG, "[Broadcast]ACTION_NEW_OUTGOING_CALL:"+outPhoneNumber);

//this.setResultData(null);

//这里可以更改呼出电话号码。如果设置为null，电话就永远不会播出了.

}

}

}

定义activity类

Java代码



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_ACTION_NEW_OUTGOING_CALL = Intent.ACTION_NEW_OUTGOING_CALL;

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(Intent.ACTION_NEW_OUTGOING_CALL);

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);

}

}

---------------------------------------------------------------------------------------------------------

要监听android打电话和接电话，只需下面2步骤

1.第一步，写一个Receiver继承自BroadcastReceiver

Java代码



public class PhoneStatReceiver extends BroadcastReceiver{

private static final String TAG = "PhoneStatReceiver";

// private static MyPhoneStateListener phoneListener = new MyPhoneStateListener();

private static boolean incomingFlag = false;

private static String incoming_number = null;

@Override

public void onReceive(Context context, Intent intent) {

//如果是拨打电话

if(intent.getAction().equals(Intent.ACTION_NEW_OUTGOING_CALL)){

incomingFlag = false;

String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);

Log.i(TAG, "call OUT:"+phoneNumber);

}else{

//如果是来电

TelephonyManager tm =

(TelephonyManager)context.getSystemService(Service.TELEPHONY_SERVICE);

switch (tm.getCallState()) {

case TelephonyManager.CALL_STATE_RINGING:

incomingFlag = true;//标识当前是来电

incoming_number = intent.getStringExtra("incoming_number");

Log.i(TAG, "RINGING :"+ incoming_number);

break;

case TelephonyManager.CALL_STATE_OFFHOOK:

if(incomingFlag){

Log.i(TAG, "incoming ACCEPT :"+ incoming_number);

}

break;

case TelephonyManager.CALL_STATE_IDLE:

if(incomingFlag){

Log.i(TAG, "incoming IDLE");

}

break;

}

}

}

}

第二步：在AndroidManifest.xml，配置写好的Receiver，并拦截相应的BroadCastAction，

另外注意加上相应的权限。

Xml代码



<receiver android:name=".filter.PhoneStatReceiver">

<intent-filter>

<action android:name="android.intent.action.PHONE_STATE"/>

<action android:name="android.intent.action.NEW_OUTGOING_CALL" />

</intent-filter>

</receiver>

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

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