隐藏软键盘

 /**
     * 根据传入控件的坐标和用户的焦点坐标，判断是否隐藏键盘，如果点击的位置在控件内，则不隐藏键盘
     *
     * @param view  控件view
     * @param event 焦点位置
     */
    public static void hideKeyboard(MotionEvent event, View view, Activity activity) {
        try {
            if (view != null && view instanceof EditText) {
                int[] location = {0, 0};
                view.getLocationInWindow(location);
                int left = location[0], top = location[1], right = left
                        + view.getWidth(), bootom = top + view.getHeight();
                // 判断焦点位置坐标是否在空间内，如果位置在控件外，则隐藏键盘
                if (event.getRawX() < left || event.getRawX() > right
                        || event.getY() < top || event.getRawY() > bootom) {
                    // 隐藏键盘
                    IBinder token = view.getWindowToken();
                    InputMethodManager inputMethodManager = (InputMethodManager) activity
                            .getSystemService(Context.INPUT_METHOD_SERVICE);
                    inputMethodManager.hideSoftInputFromWindow(token,
                            InputMethodManager.HIDE_NOT_ALWAYS);
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

父类重写dispatchTouchEvent


    @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        switch (ev.getAction()) {
            case MotionEvent.ACTION_DOWN:
                View view = getCurrentFocus();
                UtilHelper.hideKeyboard(ev, view, BaseActivity.this);//调用方法判断是否需要隐藏键盘
                break;
            default:
                break;
        }
        return super.dispatchTouchEvent(ev);
    }

2、在Activity里调用

    /**
     * 隐藏软键盘(只适用于Activity，不适用于Fragment)
     */
    public static void hideSoftKeyboard(Activity activity) {
        View view = activity.getCurrentFocus();
        if (view != null) {
            InputMethodManager inputMethodManager = (InputMethodManager) activity.getSystemService(Activity.INPUT_METHOD_SERVICE);
            inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
        }
    }
