另外一种方法：：：：

<code class = "hljs" java= "" > // 点击空白区域 自动隐藏软键盘

     public boolean onTouchEvent(MotionEvent event) {

         if ( null != this .getCurrentFocus()){

             /**

              * 点击空白位置 隐藏软键盘

              */

             InputMethodManager mInputMethodManager = (InputMethodManager) getSystemService(INPUT_METHOD_SERVICE);

             return mInputMethodManager.hideSoftInputFromWindow( this .getCurrentFocus().getWindowToken(), 0 );

         }

         return super .onTouchEvent(event);

     }</code>

在须要时手动弹出软键盘

 inputContentView.requestFocus();

                            InputMethodManager m = (InputMethodManager) inputContentView.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);

                            m.toggleSoftInput(0, InputMethodManager.HIDE_NOT_ALWAYS);
