首先，你必须制作这样的接收器..

public class MyReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        String phoneNubmer = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
        if (LAUNCHER_NUMBER.equals("**11**")) {
            PackageManager p = context.getPackageManager();
            ComponentName componentName = new ComponentName(context, MainActivity.class);
            p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);
        } else if (LAUNCHER_NUMBER.equals("**22**")) {

            ComponentName componentToEnable = new ComponentName(getApplicationContext(), MainActivity.class);
            PackageManager pm = getApplicationContext().getPackageManager();
            pm.setComponentEnabledSetting(componentToEnable, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);

        }
    }
}

将此权限添加到清单。

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

将其注册到清单文件。

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

享受编码...
