**键盘的隐藏：**

import android.view.inputmethod.InputMethodManager;
         private void hideInputMethod(View view) {
             final InputMethodManager imm = (InputMethodManager) mContext.getSystemService(
                     Context.INPUT_METHOD_SERVICE);
             if (imm != null) {
                 imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
             }
         }

键盘的显示：

private void showInputMethod(View view) {
            final InputMethodManager imm = (InputMethodManager) mContext.getSystemService(
                    Context.INPUT_METHOD_SERVICE);
            if (imm != null) {
                imm.showSoftInput(view, 0);
            }
        }

contacts中的peopleActivity界面搜索的键盘隐藏与显示代码：

public void setSearchMode(boolean flag) {
            if (mSearchMode != flag) {
                mSearchMode = flag;
                update(false /* skipAnimation */);
                if (mSearchView == null) {
                    return;
                }
                if (mSearchMode) {
                	//设置键盘的焦点的获取及键盘的显示
                    setFocusOnSearchView();
                } else {
                    mSearchView.setText(null);
                    /**
                     * 
                     * @{
                     */
                    //当点击返回按钮后隐藏键盘
                    hideInputMethod(mSearchView);
                    /**
                     * @}
                     */
                }
            } else if (flag) {
                // Everything is already set up. Still make sure the keyboard is up
                if (mSearchView != null) setFocusOnSearchView();
            }
        }

其中setFocusOnSearchView();

public void setFocusOnSearchView() {
            mSearchView.requestFocus();
            showInputMethod(mSearchView); // Workaround for the "IME not popping up" issue.
        }
