android打开和关闭软件盘工具类

1、进入界面就打开软键盘

 /**
     * 打开软键盘
     *
     * @param mEditText
     * @param mContext
     */
    public static void openKeybord(View mEditText, Context mContext) {
        InputMethodManager imm = (InputMethodManager) mContext
                .getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.showSoftInput(mEditText, InputMethodManager.RESULT_SHOWN);
        imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,
                InputMethodManager.HIDE_IMPLICIT_ONLY);
    }

2、关闭软键盘

 /**
     * 关闭软键盘
     *
     * @param mEditText
     * @param mContext
     */
    public static void closeKeybord(View mEditText, Context mContext) {
        InputMethodManager imm = (InputMethodManager) mContext.getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(mEditText.getWindowToken(), 0);
    }

封装成工具类

public class KeyBoardUtil {

    /**
     * 打开软键盘
     *
     * @param mEditText
     * @param mContext
     */
    public static void openKeybord(View mEditText, Context mContext) {
        InputMethodManager imm = (InputMethodManager) mContext
                .getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.showSoftInput(mEditText, InputMethodManager.RESULT_SHOWN);
        imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,
                InputMethodManager.HIDE_IMPLICIT_ONLY);
    }


    /**
     * 关闭软键盘
     *
     * @param mEditText
     * @param mContext
     */
    public static void closeKeybord(View mEditText, Context mContext) {
        InputMethodManager imm = (InputMethodManager) mContext.getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(mEditText.getWindowToken(), 0);
    }


    public static void hideInputMethod(Activity activity) {
        InputMethodManager imm = (InputMethodManager) activity
                .getSystemService(Context.INPUT_METHOD_SERVICE);
        View currentFocus = activity.getCurrentFocus();
        if (currentFocus != null) {
            imm.hideSoftInputFromWindow(currentFocus.getWindowToken(),
                    InputMethodManager.HIDE_NOT_ALWAYS);
        }
    }

    public static void showInputMethod(Activity activity) {
        InputMethodManager imm = (InputMethodManager) activity
                .getSystemService(Context.INPUT_METHOD_SERVICE);
        View currentFocus = activity.getCurrentFocus();
        if (currentFocus != null) {
            imm.hideSoftInputFromWindow(currentFocus.getWindowToken(),
                    InputMethodManager.HIDE_NOT_ALWAYS);
            imm.showSoftInput(currentFocus, InputMethodManager.SHOW_IMPLICIT);
        }
    }
}
