我怎么能专注于操作栏中的（当它已展开。）一个可折叠的动作视图的EditText项目和强制软键盘打开？

问题描述

限时删除！！

我使用的杰克沃顿商学院的优秀 ActionBarSherlock 的图书馆，有一个可折叠的搜索动作视图。我想弹出当搜索动作视图扩展了软键盘。

I am using Jake Wharton's excellent ActionBarSherlock library and have a collapsible search action view. I want to popup the soft keyboard when the search action view is expanded.

我们可以阅读使用DialogFragments这样的DialogFragment的推荐的方法由谷歌的博客文章（改变一个位可读性）。

We can read a recommended way of doing this in a DialogFragment in the "Using DialogFragments" blog post by Google (altered a bit for readability).

// Show soft keyboard automatically
mEditText.requestFocus();
int mode = WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE;
getDialog().getWindow().setSoftInputMode(mode);

似乎这不是扩大和要求集中了可折叠的EditText动作视图。我现在有这一点。

This does not seem to work when expanding and requesting focus on a collapsable EditText action view. I currently have this.

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getSupportMenuInflater();
    inflater.inflate(R.menu.my_activity, menu);

    MenuItem menuItem = menu.findItem(R.id.menu_search);
    final EditText searchText = (EditText) menuItem.getActionView();

    menuItem.setOnActionExpandListener(new OnActionExpandListener() {
        @Override
        public boolean onMenuItemActionCollapse(MenuItem item) {
            return true; // Return true to collapse action view
        }

        @Override
        public boolean onMenuItemActionExpand(MenuItem item) {
            searchText.requestFocus();
            int mode = WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE;
            getWindow().setSoftInputMode(mode);
            return true; // Return true to expand action view
        }
    });
}

下面是在my_activity菜单的xml文件我的菜单项的定义：

Here's my menu item definition in the my_activity menu xml file:

<item
    android:id="@+id/menu_search"
    android:icon="@drawable/ic_menu_search"
    android:actionLayout="@layout/collapsible_edittext"
    android:showAsAction="always|collapseActionView"
    android:title="@string/menu_search"/>

...和collapsible_edittext动作布局

... and the collapsible_edittext action layout

<?xml version="1.0" encoding="utf-8"?>
<EditText xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:hint="@string/hint_search"
    android:imeOptions="actionSearch"
    android:inputType="text"
    android:focusable="true"
    android:focusableInTouchMode="true" />

警告：我不想的动力的软键盘。当用户具有一个硬件键盘请求焦点是足够的。

Caveat: I do not want to force the soft keyboard. When the user has a hardware keyboard requesting focus is sufficient.

任何想法的人？

推荐答案

也许不是requestFocus从来没有发生在code的问题，因为searchText没有扩大了吗？我不知道，反正......这个工作对我来说：

Maybe the requestFocus never occurred in the code in the question because the searchText was not expanded yet? I don't know, anyway... this worked for me:

@Override
public boolean onMenuItemActionExpand(MenuItem item) {
    searchText.post(new Runnable() {
        @Override
        public void run() {
            searchText.requestFocus();
            InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.showSoftInput(searchText, InputMethodManager.SHOW_IMPLICIT);
        }
    });
    return true; // Return true to expand action view
}
