ブラックベリーでサウンドプロファイル変更・音量変更を聞くアプリを作りたいです。ターゲット バージョンは 5、6、7 です。Blackberry のドキュメントを検索しましたが、何も見つかりませんでした。検索中に見つけた2つのこと。

  1. globaleventlistener これにはそのイベントの GUID が必要です。このイベントはイベント GUID リストに記載されていません。

  2. 通知マネージャー Notificationmanager は、レジスターの 1 つに役立つ可能性があります。しかし、システムイベントに登録する方法がわかりません。GUID も必要です。

何か見逃した場合は、リソースを共有してください。ブラックベリーの開発は初めてです。私を助けてください。

ありがとう、パート・シャー

これは、両方が探しているものを処理する必要があります。カスタム keyListner については、次のようになります。

package mypackage;

//All output to the console.
//Yet from testing only KeyUp and KeyDown are ever called and handle all special buttons 
//Volume, Dial, EndCall, etc...
    public boolean keyChar(char key, int status, int time) {
        System.out.println("CHAR PRESSED: <"+key+"/>");
        return false;
    }

    public boolean keyDown(int keycode, int time) {
        System.out.println("KEY PRESSED (DOWN): < BUTTON="+getKey(keycode)+" ID="+keycode+" KEY VALUE= "+Keypad.key(keycode)+"/>");
        return false;
    }



public boolean keyRepeat(int keycode, int time) { 
    System.out.println("KEY REPEAT: < BUTTON="+getKey(keycode)+" ID="+keycode+"/>");
    return false;
}

public boolean keyStatus(int keycode, int time) {
    System.out.println("KEY STATUS: < BUTTON="+getKey(keycode)+" ID="+keycode+"/>");
    return false;
}

public boolean keyUp(int keycode, int time) {
    System.out.println("KEY PRESSED (UP): < BUTTON="+getKey(keycode)+" ID="+keycode+" KEY VALUE= "+Keypad.key(keycode)+"/>");
    return false;
}

public String getKey(int keycode){
    System.out.println("[EVENT ID] = "+ keycode);
    //Converts the provided keycode into a value which can be compared to the keypad 
    //constants
    keycode = Keypad.key(keycode);

    System.out.println("[KEY ID] = "+ keycode);
