Question

我想在android中获取被叫号码但是当我开始拨出呼叫时它失败了我正在使用广播接收器并在服务中注册它以保持监听，如果这里没有关注的活动是我的代码。

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 Class

  @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();


}

服务

  @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

你是否意识到这一点：

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

您使用的是ctx而不是上下文。

Answer 4

感谢所有我已经解决了问题我自己在烤箱中使用了错误的上下文正确的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();


 }
