在廣播接收器中接收呼叫意圖

Question

我想在android中獲取被叫號碼，但是當我開始撥出電話失敗時，我正在使用廣播接收器並將其注冊在服務中，以便在活動不集中時繼續收聽，這是我的代碼。

Menifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.vampirepc.androidservice" >

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme" >
    <activity android:name=".MainActivity" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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


            </action>
        </intent-filter>
    </activity>

    <service android:name=".MyService" />


    <receiver
        android:name="com.example.vampirepc.androidservice.OutgoingReceiver"
        android:enabled="true"
        android:exported="true" >
        <intent-filter>
            <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        </intent-filter>
    </receiver>

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

BroadcastReceiver類

  @Override
public void onReceive(Context context, Intent intent) {

    Toast.makeText(ctx,
            "Inside broadcast",
            Toast.LENGTH_LONG).show();


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

    Toast.makeText(context, "Outgoing call catched: " + phoneNumber, Toast.LENGTH_LONG).show();


}

服務

  @Override
public void onCreate() {
    Toast.makeText(getApplicationContext(),"Service created",Toast.LENGTH_SHORT).show();

    try {


        IntentFilter filter = new IntentFilter("android.intent.action.NEW_OUTGOING_CALL");

        OutgoingReceiver myReceiver = new OutgoingReceiver();
        registerReceiver(myReceiver, filter);


    } catch (Exception e) {

        Toast.makeText(getApplicationContext(),"Exception is "+String.valueOf(e),Toast.LENGTH_SHORT).show();

    }



}

Answer 3

您是否意識到這一點：

Toast.makeText(ctx,
        "Inside broadcast",
        Toast.LENGTH_LONG).show();

您使用ctx而不是上下文。

Answer 4

感謝所有我已經解決的問題，我自己在烤面包機中使用了錯誤的上下文，正確的onReceive是。 我正在使用初始化的ctx。

Context ctx;


   public void onReceive(Context context, Intent intent) {

    Toast.makeText(context, "this is not shown"     , Toast.LENGTH_LONG).show();



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

    Toast.makeText(context, "Outgoing call catched: " + phoneNumber, Toast.LENGTH_LONG).show();


 }
