Android编程实现点击EditText之外的控件隐藏软键盘功能

...public static void hideKeyboard(Context ctx) {    if (ctx != null) {      View view = ((Activity) ctx).getCurrentFocus();      if (view != null) {        InputMethodManager inputManager = (InputMethodManager) ctx            .getSystemService(Context.INPUT_METHOD_SERVICE);        inputManager.hideSoftInputFromWindow(view.getWindowToken(),            InputMethodManager.HIDE_NOT_ALWAYS);      }    }}

public static void setupUI(View view, final Context ctx) {    //Set up touch listener for non-text box views to hide keyboard.    if(!(view instanceof EditText)) {      view.setOnTouchListener(new OnTouchListener() {        public boolean onTouch(View v, MotionEvent event) {          hideKeyboard(ctx);          return false;        }      });    }    //If a layout container, iterate over children and seed recursion.    if (view instanceof ViewGroup) {      for (int i = 0; i < ((ViewGroup) view).getChildCount(); i++) {        View innerView = ((ViewGroup) view).getChildAt(i);        setupUI(innerView, ctx);      }    }  }...}

UtilApp.setupUI((RelativeLayout) findViewById(R.id.login_parent), mContext);
