Android的扩展菜单（隐藏/取消隐藏菜单） [英] android expandable menu (hiding/unhiding menu)

问题描述

在我的应用程序的布局，我有一个设置按钮....我们按下时，它会显示一些子菜单....当我们再次推它，它会隐藏所有的子菜单....样子扩展列表视图，但不完全一样....只是躲在/为了得到另一个观点一定的空间，取消隐藏菜单....我怎么能做到这一点？

in my application layout, i have a setting button....when we push it, it will show some sub menus....when we push it again, it will hide all sub menus....look like expandable listview, but not exactly like that....just hiding/unhiding menu in order to get some space for another views....how can i do that?

这里要说的是正是我想要做的截图

here is the screenshots that exactly what i want to do

隐藏菜单

取消隐藏菜单

这里的我的xml文件：

<RelativeLayout
android:layout_height="fill_parent"
android:layout_width="fill_parent">
    <EditText
        android:id="@+id/Editsearch"
        android:hint="Enter keyword..."
        android:layout_alignParentLeft="true"
        android:singleLine="true"
        android:layout_width="fill_parent"
        android:layout_toLeftOf="@+id/search"
        android:layout_height="wrap_content" />
    <ImageButton
        android:id="@+id/search"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/button_search"
        android:layout_alignParentRight="true" />
    <Spinner
        android:id="@+id/province"
        android:layout_width="135dp"
        android:layout_height="45dp"
        android:layout_below="@+id/Editsearch"
        android:layout_toLeftOf="@+id/setting"
        android:textSize="12dip"
        android:textStyle="bold"
        android:background="@android:drawable/btn_default"
    />
    <ImageButton
        android:id="@+id/setting"
        android:layout_width="wrap_content"
        android:layout_height="45dip"
        android:layout_below="@+id/Editsearch"
        android:src="@drawable/button_setting"
        android:layout_alignParentRight="true" />
    <Spinner
        android:id="@+id/Category"
        android:layout_width="135dp"
        android:layout_height="45dp"
        android:text="Category"
        android:layout_below="@+id/Editsearch"
        android:layout_alignParentLeft="true"
        android:background="@android:drawable/btn_default" />
        <!-- Job Category title-->
    <TextView
        android:id="@+id/Title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="#000000"
        android:typeface="serif"
        android:textSize="13dip"
        android:layout_below="@+id/province"
        android:layout_gravity="center"

        android:text="Total Job : 1982"
        android:textStyle="bold" />
    <ListView
        android:id="@+id/list"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/Title"
        android:listSelector="@drawable/list_selector" />
</RelativeLayout>

推荐答案

这是非常简单的。
只要将这些3个按钮的布局和设置隐藏/取消隐藏按钮，点击该布局走了/可见光的知名度。

It is very simple. Just place those 3 buttons in a layout and set the visibility of that layout to gone/visible on click of hide/unhide button.

编辑：

它会像把你的纺纱厂，你想隐藏/取消隐藏在布局，并为它提供一个ID。

It will be like put your spinners which you like to hide/unhide in a layout and provide an ID for it.

<ImageButton
        android:id="@+id/setting"
        android:layout_width="wrap_content"
        android:layout_height="45dip"
        android:layout_alignParentRight="true"
        android:layout_below="@+id/Editsearch"
        android:src="@drawable/button_setting" />

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" 
    **android:id="@+id/submenu_layout"**
    android:layout_below="@+id/Editsearch"
    >
    <Spinner
        android:id="@+id/category1"
        android:layout_width="135dp"
        android:layout_height="45dp"
        android:layout_alignParentLeft="true"
        android:background="@android:drawable/btn_default"
        android:text="Category" />
    <Spinner
        android:id="@+id/category2"
        android:layout_width="135dp"
        android:layout_height="45dp"
        android:layout_alignParentLeft="true"
        android:layout_below="@id/category1"
        android:background="@android:drawable/btn_default"
        android:text="Category" />
    <Spinner
        android:id="@+id/category3"
        android:layout_width="135dp"
        android:layout_height="45dp"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/category2"
        android:background="@android:drawable/btn_default"
        android:text="Category" />
    </RelativeLayout>

然后用这个ID来拿在code此布局的参考。

Then use this id to take the reference of this layout in your code.

RelativeLayout submenuLayout = (RelativeLayout) findViewById(R.id.submenu_layout);

编辑2：

在设定的ImageButton那的OnClick：

After that OnClick of setting imageButton :

 if(submenuLayout .getVisibility() == View.VISIBLE)
    submenuLayout .setVisibility(View.GONE);
    else
        submenuLayout .setVisibility(View.VISIBLE);
