安卓键盘处理

 /**
     * EditText获取焦点并显示软键盘
     */
    public static void showSoftInputFromWindow(Activity activity, EditText editText) {
        editText.setFocusable(true);
        editText.setFocusableInTouchMode(true);
        editText.requestFocus();
        //显示软键盘
        activity.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
        //如果上面的代码没有弹出软键盘 可以使用下面另一种方式
        //InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
        // imm.showSoftInput(editText, 0);

    }
 /**
     * 隐藏软键盘
     *
     * @param activity
     */
    public static void hideKeyBoard(Activity activity) {
        InputMethodManager imm = (InputMethodManager) activity
                .getApplicationContext().getSystemService(
                        Context.INPUT_METHOD_SERVICE);
        View view = activity.getCurrentFocus();
        if (view != null) {
            imm.hideSoftInputFromWindow(view.getWindowToken(),
                    InputMethodManager.HIDE_NOT_ALWAYS);
        }
    }

    public static void showKeyBoard(Activity activity) {
        InputMethodManager imm = (InputMethodManager) activity
                .getApplicationContext().getSystemService(
                        Context.INPUT_METHOD_SERVICE);
        View view = activity.getCurrentFocus();
        if (view != null) {
            imm.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT);
        }
    }

多个文本框可以加入以下代码：

                android:focusable="true"
                android:focusableInTouchMode="true"
