我创建了一个自定义的softKeyboard，我希望在设备上的所有应用程序只能使用此键盘。我添加了一个密码限制访问输入选择设置页面。问题是，当有多个可用softkeyboards通知出现。有没有什么办法可以禁用此输入选择通知或限制用户选择其他键盘。

I have created a custom softKeyboard and I want all application in the devices use this keyboard only. I have added a password restriction to access input Selection setting page. The problem is the notification appears when there are multiple softkeyboards available. Is there any way I can disable this input selection notification or to restrict user to choose the other keyboard.

我想分享我自己的问题的答所以它可以帮助其他人谁正面临着同样的问题。我已经在上面添加上寡妇的自定义视图，以便在状态栏，避免触摸事件。下面是我的code。

I want to share my own question's ans so it can help others who are facing same issue. I have added a custom view on widow at the top so that the status bar to avoid touch event. below is my code.

public class ClearStatusBar extends Service {

    private WindowManager mWindowManager;
    private NotificationManager mNotificationManager;
    private static View statusbar;



 @Override
public void onCreate() {
    super.onCreate();
    mWindowManager = (WindowManager) getSystemService(Context.WINDOW_SERVICE);
    mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

}


 private WindowManager.LayoutParams getWindowManagerParams() {
        WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                WindowManager.LayoutParams.MATCH_PARENT,
                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.TYPE_SYSTEM_ERROR ,
             // Keeps the button presses from going to the background window
                WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE |
                // Enables the notification to recieve touch events
                WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL |
                // Draws over status bar
                WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN,
                PixelFormat.TRANSLUCENT); // must be translucent to support KitKat gradient
        params.gravity = Gravity.TOP;
        params.x=0;
        int statusBarHeight = getStatusBarHeight();
        params.height = (statusBarHeight>25?statusBarHeight:25);
        return params;
    }

 public int getStatusBarHeight() {
      int result = 0;
      int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
      if (resourceId > 0) {
          result = getResources().getDimensionPixelSize(resourceId);
      }
      return result;
}



@Override
public IBinder onBind(Intent intent) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    if(statusbar == null){
        statusbar = new View(this);
        statusbar.setBackgroundColor(Color.parseColor("#20000000"));
        mWindowManager.addView(statusbar, getWindowManagerParams());
        if(statusbar != null){
            statusbar.setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);
        }
    }

    return START_STICKY;
}

@Override
public void onDestroy() {
    if(statusbar != null){
        mWindowManager.removeView(statusbar);
        statusbar = null;
    }
    super.onDestroy();

}

}
