在DrawerLayout形式从右向左滑动ExpandableListView [英] slide ExpandableListView at DrawerLayout form right to left

问题描述

如何在DrawerLayout表格右侧滑动ExpandableListView至左

我想告诉ExpandableListView在屏幕的右上角，我怎么能做到这一点？

 ＆LT; android.support.v4.widget.DrawerLayout
    的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
    机器人：ID =@ + ID / drawer_layout
    机器人：layout_width =match_parent
    机器人：layout_height =match_parent＆GT;

    ＆LT;的FrameLayout
        机器人：ID =@ + ID / content_frame
        机器人：layout_width =match_parent
        机器人：layout_height =match_parent/＆GT;

    ＆LT; ExpandableListView
        机器人：ID =@ + ID / left_drawer
        机器人：layout_width =240dp
        机器人：layout_height =match_parent
        机器人：layout_gravity =开始
        机器人：choiceMode =singleChoice
        机器人：分隔=@机器人：彩色/白
        机器人：dividerHeight =0dp
      /＆GT;
＆LT; /android.support.v4.widget.DrawerLayout>
 

解决方案

修改安卓layout_gravity =开始为安卓layout_gravity = 结束或安卓layout_gravity =正确的（使用结束将放抽屉屏幕从右到左的配置）

左侧

修改

看来， ActionBarDrawerToggle 正在寻找在同一侧操作栏主页图标抽屉（Gravity.START $ C>），这将是左侧的左到右的布局方向。如果你将永远有在右边的抽屉里，你可以做这样的事情：

  mDrawerToggle =新ActionBarDrawerToggle（这一点，mDrawer，R.drawable.ic_drawer，R.string.open_drawer，R.string.close_drawer）{

    @覆盖
    公共布尔onOptionsItemSelected（菜单项项）{
        如果（项目= NULL和放大器;！＆安培; item.getItemId（）== android.R.id.home）{
            如果（mDrawer.isDrawerOpen（Gravity.RIGHT））{
                mDrawer.closeDrawer（Gravity.RIGHT）;
            } 其他 {
                mDrawer.openDrawer（Gravity.RIGHT）;
            }
        }
        返回false;
    }
};
 

如果抽屉永远是操作栏主页图标相反，你可以使用 Gravity.END 代替。

How to slide ExpandableListView at DrawerLayout form right to left

i want to show ExpandableListView at right corner of screen , how can i do that ??

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <ExpandableListView
        android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice"
        android:divider="@android:color/white"
        android:dividerHeight="0dp"
      />
</android.support.v4.widget.DrawerLayout>

解决方案

Change android:layout_gravity="start" to either android:layout_gravity="end" or android:layout_gravity="right" (using end will put the drawer on the left side of the screen for right-to-left configurations)

EDIT

It appears that the ActionBarDrawerToggle is looking for a drawer on the same side as the action bar Home icon (Gravity.START), which would be the left side for left-to-right layout directions. If you will always have the drawer on the right, you could do something like this:

mDrawerToggle = new ActionBarDrawerToggle(this, mDrawer, R.drawable.ic_drawer, R.string.open_drawer, R.string.close_drawer) {

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item != null && item.getItemId() == android.R.id.home) {
            if (mDrawer.isDrawerOpen(Gravity.RIGHT)) {
                mDrawer.closeDrawer(Gravity.RIGHT);
            } else {
                mDrawer.openDrawer(Gravity.RIGHT);
            }
        }
        return false;
    }
};

If the drawer will always be opposite the action bar Home icon, you could use Gravity.END instead.
