ANDROID 经过监听来电去电，并弹出悬浮窗

要监听android打电话和接电话，有一种的是经过新建一个Receiver继承自BroadcastReceiver。

还有一种也可经过PhoneStateListener来实现。今天就说说后面一种，废话不说了，直接上代码

package com.webphone; import org.apache.http.message.BasicNameValuePair; import android.content.Context; import android.content.Intent; import android.graphics.PixelFormat; import android.telephony.PhoneStateListener; import android.telephony.TelephonyManager; import android.view.WindowManager; import android.widget.TextView;   public class TelListener extends PhoneStateListener {                    private Context context;          private WindowManager wm; //系统管理          private TextView tv; //悬浮窗文本          private Boolean isInComing= false ; //标记是否为来电          public TelListener(Context context){                  this .context = context;          }          @Override          public void onCallStateChanged( int state, String incomingNumber) {                  switch (state)                  {                  case TelephonyManager.CALL_STATE_RINGING: //此时为响铃状态                      {                          isInComing= true ; //若是有响铃状态，则表示此时为来电                         //如下代码为悬浮窗显示来电号码                         //定义窗口布局                          wm = (WindowManager)context.getApplicationContext().getSystemService(Context.WINDOW_SERVICE);                          WindowManager.LayoutParams params = new WindowManager.LayoutParams();                          //设置窗口布局居于全部之上                         params.type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY;                          //使窗口失去焦点                          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;                          //背景透明                          params.format = PixelFormat.RGBA_8888;                          tv = new TextView(context);                          String comingNum=  GetInComingNumber();                          tv.setTextSize( 40 );                          tv.setText( "来电" +comingNum);                          wm.addView(tv, params); //添加到系统窗口中。                      } break ;                  case TelephonyManager.CALL_STATE_OFFHOOK: //若是处于忙时状态                      {                          if (!isInComing) //若是非来电状态，则标记为去电                          {                              if (wm != null )                                  wm.removeView(tv);                             //如下代码为悬浮窗显示去电号码                              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.setTextSize( 40 );                              //获取实际去电号码，此处使用自定义方法，（这边去电号码本身想办法保存）                              String outcomingNum=AppData.getRealNum();                              tv.setText( "去电" + outcomingNum);                              wm.addView(tv, params);                              isInComing= false ; //标记为非来电                          }                      } break ;                  case TelephonyManager.CALL_STATE_IDLE:                      {                          if (wm != null && tv!= null )                              wm.removeView(tv);                      } break ;                  }                  super .onCallStateChanged(state, incomingNumber);          } }

固然了，虽然代码是OK了，可是记得配置好权限。

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

虽然如此，既然是弹出悬浮窗，那也该配置下弹出悬浮窗的权限吧。

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

都好了，那最重要的一步可别忘记了，在启动的时候添加监听，而且注册广播。

1 2 3

TelephonyManager telM = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);        //设置监听        telM.listen( new TelListener( this .getContext()), PhoneStateListener.LISTEN_CALL_STATE);

还要在AndroidManifest.xml中注册广播接收类

1 2 3 4 5

< receiver android:name = ".PhoneBootReceiver" >              < intent-filter >                      < action android:name = "android.intent.action.BOOT_COMPLETED" />              </ intent-filter >      </ receiver >

若是想要接收开机广播，而后在接收到广播后注册来电监听。接收开机广播须要有“RECEIVE_BOOT_COMPLETED”权限，AndroidManifest.xml 中申明以下

 

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

 

其实android API自己是没法监听去电的，这只是一种转弯的方法。。

PS：在转个弯，你就能够实现来电归属地查询了。。

目前个人处理方式是接收开机广播，而后在接收到广播后注册来电监听。接收开机广播须要有“android.permission.RECEIVE_BOOT_COMPLETED”权限，manifest中申明以下
