ANDROID 經過監聽來電去電，並彈出懸浮窗

要監聽android打電話和接電話，有一種的是經過新建一個Receiver繼承自BroadcastReceiver。

還有一種也可經過PhoneStateListener來實現。今天就說說後面一種，廢話不說了，直接上代碼

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72

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; //系統管理          private TextView tv; //懸浮窗文本          private Boolean isInComing= false ; //標記是否爲來電          public TelListener(Context context){                  this .context = context;          }          @Override          public void onCallStateChanged( int state, String incomingNumber) {                  switch (state)                  {                  case TelephonyManager.CALL_STATE_RINGING: //此時爲響鈴狀態                      {                          isInComing= true ; //若是有響鈴狀態，則表示此時爲來電                         //如下代碼爲懸浮窗顯示來電號碼                         //定義窗口布局                          wm = (WindowManager)context.getApplicationContext().getSystemService(Context.WINDOW_SERVICE);                          WindowManager.LayoutParams params = new WindowManager.LayoutParams();                          //設置窗口布局居於全部之上                         params.type = WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY;                          //使窗口失去焦點                          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( "來電" +comingNum);                          wm.addView(tv, params); //添加到系統窗口中。                      } break ;                  case TelephonyManager.CALL_STATE_OFFHOOK: //若是處於忙時狀態                      {                          if (!isInComing) //若是非來電狀態，則標記爲去電                          {                              if (wm != null )                                  wm.removeView(tv);                             //如下代碼爲懸浮窗顯示去電號碼                              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 );                              //獲取實際去電號碼，此處使用自定義方法，（這邊去電號碼本身想辦法保存）                              String outcomingNum=AppData.getRealNum();                              tv.setText( "去電" + outcomingNum);                              wm.addView(tv, params);                              isInComing= false ; //標記爲非來電                          }                      } break ;                  case TelephonyManager.CALL_STATE_IDLE:                      {                          if (wm != null && tv!= null )                              wm.removeView(tv);                      } break ;                  }                  super .onCallStateChanged(state, incomingNumber);          } }

固然了，雖然代碼是OK了，可是記得配置好權限。

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

雖然如此，既然是彈出懸浮窗，那也該配置下彈出懸浮窗的權限吧。

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

都好了，那最重要的一步可別忘記了，在啓動的時候添加監聽，而且註冊廣播。

1 2 3

TelephonyManager telM = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);        //設置監聽        telM.listen( new TelListener( this .getContext()), PhoneStateListener.LISTEN_CALL_STATE);

還要在AndroidManifest.xml中註冊廣播接收類

1 2 3 4 5

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

若是想要接收開機廣播，而後在接收到廣播後註冊來電監聽。接收開機廣播須要有「RECEIVE_BOOT_COMPLETED」權限，AndroidManifest.xml 中申明以下

 

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

 

其實android API自己是沒法監聽去電的，這只是一種轉彎的方法。。

PS：在轉個彎，你就能夠實現來電歸屬地查詢了。。

目前個人處理方式是接收開機廣播，而後在接收到廣播後註冊來電監聽。接收開機廣播須要有「android.permission.RECEIVE_BOOT_COMPLETED」權限，manifest中申明以下
