呼叫监听 android

 

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  

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

<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  

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

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

 

 然后注册广播接收类

 

Xml代码  

1. <receiver android:name=".PhoneBootReceiver">  
2.     <intent-filter>  
3.         <action android:name="android.intent.action.BOOT_COMPLETED" />  
4.     </intent-filter>  
5. </receiver>  

<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  

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

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

 

 然后添加监听

 

Java代码  

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

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  

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

<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  

1. public class TelListener extends PhoneStateListener {   
2.        
3.        
4.     private Context context;   
5.     private WindowManager wm;   
6.     private TextView tv;   
7.     public TelListener(Context context){   
8.         this.context = context;   
9.     }   
10.   
11.     @Override   
12.     public void onCallStateChanged(int state, String incomingNumber) {   
13.         // TODO Auto-generated method stub   
14.         super.onCallStateChanged(state, incomingNumber);   
15.         if(state == TelephonyManager.CALL_STATE_RINGING){   
16.                
17.             wm = (WindowManager)context.getApplicationContext().getSystemService(Context.WINDOW_SERVICE);     
18.             WindowManager.LayoutParams params = new WindowManager.LayoutParams();     
19.             params.type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY;     
20.             params.flags = WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;    
21.                  
22.             params.width = WindowManager.LayoutParams.WRAP_CONTENT;     
23.             params.height = WindowManager.LayoutParams.WRAP_CONTENT;     
24. <SPAN style="WHITE-SPACE: pre">         </SPAN>params.format = PixelFormat.RGBA_8888;   
25.             tv = new TextView(context);    
26.             tv.setText("这是悬浮窗口，来电号码：" + incomingNumber);   
27.             wm.addView(tv, params);   
28.                        
29.         }else if(state == TelephonyManager.CALL_STATE_IDLE){   
30.             if(wm != null){   
31.                 wm.removeView(tv);   
32.             }   
33.         }   
34.     }   
35. }  

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;  
			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  

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

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

 

设置窗口类型在所有窗口之上

 

Java代码  

1. params.type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY;   

params.type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY; 

 

别忘了

 

Java代码  

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

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  

1. params.format = PixelFormat.RGBA_8888;  

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  

1. wm.addView(tv, params);  

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  

1. wm.removeView(tv);  

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  

1. params.type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY;   

params.type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY; 

修改为

Java代码  

1. params.type = WindowManager.LayoutParams.TYPE_PHONE;   

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  

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

<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  

1. package com.zhouzijing.android.demo;   
2.   
3. import android.content.BroadcastReceiver;   
4. import android.content.Context;   
5. import android.content.Intent;

9. public class BroadcastReceiverMgr extends BroadcastReceiver {   
10.        
11.     private final String TAG = MyBroadcastReceiver.TAG;   
12.   
13.     @Override  
14.     public void onReceive(Context context, Intent intent) {   
15.         String action = intent.getAction();   
16.         Log.i(TAG, "[Broadcast]"+action);   
17.            
18.         //呼入电话   
19.         if(action.equals(MyBroadcastReceiver.B_PHONE_STATE)){   
20.             Log.i(TAG, "[Broadcast]PHONE_STATE");   
21.             doReceivePhone(context,intent);   
22.         }   
23.     }   
24.        
25.     /**  
26.      * 处理电话广播.  
27.      * @param context  
28.      * @param intent  
29.      */  
30.     public void doReceivePhone(Context context, Intent intent) {   
31.         String phoneNumber = intent.getStringExtra(   
32. TelephonyManager.EXTRA_INCOMING_NUMBER);   
33.         TelephonyManager telephony =    
34. (TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);   
35.         int state = telephony.getCallState();   
36.         switch(state){   
37.         case TelephonyManager.CALL_STATE_RINGING:   
38.             Log.i(TAG, "[Broadcast]等待接电话="+phoneNumber);   
39.             break;   
40.         case TelephonyManager.CALL_STATE_IDLE:   
41.             Log.i(TAG, "[Broadcast]电话挂断="+phoneNumber);   
42.             break;   
43.         case TelephonyManager.CALL_STATE_OFFHOOK:   
44.             Log.i(TAG, "[Broadcast]通话中="+phoneNumber);   
45.             break;   
46.         }   
47.     }   
48. }  

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

11. import android.view.View;   
12.   
13. public class MyBroadcastReceiver extends Activity {   
14.     public final static String TAG = "MyBroadcastReceiver";   
15.        
16.     public final static String B_PHONE_STATE =    
17. TelephonyManager.ACTION_PHONE_STATE_CHANGED;   
18.        
19.     private BroadcastReceiverMgr mBroadcastReceiver;   
20.        
21.     @Override  
22.     public void onCreate(Bundle savedInstanceState) {   
23.         super.onCreate(savedInstanceState);   
24.         setContentView(R.layout.my_broadcast_receiver);   
25.     }      
26.   
27.     //按钮1-注册广播   
28.     public void registerIt(View v) {   
29.         Log.i(TAG, "registerIt");   
30.         mBroadcastReceiver = new BroadcastReceiverMgr();   
31.         IntentFilter intentFilter = new IntentFilter();   
32.         intentFilter.addAction(B_PHONE_STATE);   
33.         intentFilter.setPriority(Integer.MAX_VALUE);   
34.         registerReceiver(mBroadcastReceiver, intentFilter);   
35.     }   
36.        
37.     //按钮2-撤销广播   
38.     public void unregisterIt(View v) {   
39.         Log.i(TAG, "unregisterIt");   
40.         unregisterReceiver(mBroadcastReceiver);   
41.     }   
42.        
43. }

方式二：通过监听器来实现

55.     }   
56.        
57.        
58.   
59.        
60. }
