Question

我正在运行以下代码，正在编译，但我没有得到任何结果或烤面包显示请帮助......

CustomBroadcastReceiver.java 此类将接收操作电话状态更改并将实例化customephonestatelistener

public class CustomBroadcastReceiver extends BroadcastReceiver {

TelephonyManager telephony = 
(TelephonyManager)context.getSystemService(Context.TELEPHONY_SERVICE);

CustomPhoneStateListener customPhoneListener = new CustomPhoneStateListener(context);

telephony.listen(customPhoneListener, PhoneStateListener.LISTEN_CALL_STATE);


Bundle bundle = intent.getExtras();
String phoneNr= bundle.getString("incoming_number");
    Log.v(TAG, "phoneNr: "+phoneNr);
    Toast toast = Toast.makeText(context, "phoneNr: "+phoneNr, Toast.LENGTH_LONG);
    toast.show();
}
}

CustomPhonestateListener.java

这个类是主要的操作类

public class CustomPhoneStateListener extends PhoneStateListener {

private static final String TAG = "CustomPhoneStateListener";

private Context mContext;

public CustomPhoneStateListener(Context context) {


// TODO Auto-generated constructor stub
mContext = context;
}

public void onCallStateChanged(int state, String incomingNumber){

    Log.v(TAG, "WE ARE INSIDE!!!!!!!!!!!");

     Log.v(TAG, incomingNumber);
    Toast toast = Toast.makeText(mContext, "WE ARE INSIDE!!!!!!!!!!!", Toast.LENGTH_LONG);
    toast.show();

    switch(state){
            case TelephonyManager.CALL_STATE_RINGING:
                    Log.d(TAG, "RINGING");
                    break;
    }

的AndroidManifest.xml

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

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <receiver android:name=".MyBroadcastReceiver">
            <intent-filter>
                    <action android:name="android.intent.action.PHONE_STATE" />

            </intent-filter>
    </receiver>
</application>

Thnx的答案...我尝试了另一种方法，以下代码似乎工作..加入接收器和phonestatelistener .. 但现在问题是我必须重新启动设备才能启动此服务< /strong> ......现在我错了哪个建议？

public class IncomingCallReciever extends BroadcastReceiver { private Context mContext; private Intent mIntent; @Override public void onReceive(Context context, Intent intent) { mContext = context; mIntent = intent; TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE); int events = PhoneStateListener.LISTEN_CALL_STATE; tm.listen(phoneStateListener, events); } private final PhoneStateListener phoneStateListener = new PhoneStateListener() { @Override public void onCallStateChanged(int state, String incomingNumber) { String callState = "UNKNOWN"; switch (state) { case TelephonyManager.CALL_STATE_IDLE: callState = "IDLE"; break; case TelephonyManager.CALL_STATE_RINGING: // -- check international call or not. if (incomingNumber.startsWith("00")) { Toast.makeText(mContext,"International Call- " + incomingNumber,Toast.LENGTH_LONG).show(); callState = "International - Ringing (" + incomingNumber+ ")"; } else { Toast.makeText(mContext, "Local Call - " + incomingNumber, Toast.LENGTH_LONG).show(); callState = "Local - Ringing (" + incomingNumber + ")"; } break; case TelephonyManager.CALL_STATE_OFFHOOK: String dialingNumber = mIntent.getStringExtra(Intent.EXTRA_PHONE_NUMBER); if (dialingNumber.startsWith("00")) { Toast.makeText(mContext,"International - " + dialingNumber,Toast.LENGTH_LONG).show(); callState = "International - Dialing (" + dialingNumber+ ")"; } else { Toast.makeText(mContext, "Local Call - " + dialingNumber,Toast.LENGTH_LONG).show(); callState = "Local - Dialing (" + dialingNumber + ")"; } break; } Log.i(">>>Broadcast", "onCallStateChanged " + callState); super.onCallStateChanged(state, incomingNumber); } }; }

问题出在您的清单文件中，您必须拥有：

<receiver android:name=".MyReceiver" >
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />                
</intent-filter>
</receiver>

而不是：

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

“但现在问题是我必须重新启动设备才能启动此服务。现在我错了哪个建议？”

您必须重新启动手机的原因是，在您的AndroidManifest.xml文件中，您只允许执行一次操作...

<!-- Your Problem is here -->
<action android:name="android.intent.action.BOOT_COMPLETED" />

您已将BroadcastReceiver设置为仅在手机启动时启动要解决此问题，您需要使用DR VOLT提供的答案。

只需将动作PHONE_STATE和NEW_OUTGOING_CALL添加到您的接收器中例如：

<receiver android:name=".MyReceiver" >
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
<action android:name="android.intent.action.NEW_OUTGOING_CALL" />
<action android:name="android.intent.action.BOOT_COMPLETED" />           
</intent-filter>
</receiver>

这将在发生这些操作时启动广播接收器。

在android中调用时的传入号码？
