[英]How to add tabs at bottom
I have a tabhost which contains three tabs, connected with three activities. 我有一个tabhost,其中包含三个选项卡,与三个活动相关联。 All three tabs are in the upper side.
所有三个选项卡都在上侧。 How can I make these three tabs at the bottom?
如何在底部显示这三个选项卡?
I found this, but there are still some problems. 我找到了,但是仍然存在一些问题。
This is my tabhost XML file: 这是我的tabhost XML文件:
<?xml version="1.0" encoding="UTF-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1" />
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0"/>
</LinearLayout>
</TabHost>
In my TabActivity class, I have following code: 在我的TabActivity类中,我有以下代码:
setContentView(R.layout.tabs);
TabHost mTabHost = (TabHost)findViewById(android.R.id.tabhost);
mTabHost.addTab(mTabHost.newTabSpec("tab_test1").setIndicator("TAB 1").setContent(new Intent(AndroisTabViewActivity.this,TabActivity1.class)));
mTabHost.addTab(mTabHost.newTabSpec("tab_test2").setIndicator("TAB 2").setContent(new Intent(AndroisTabViewActivity.this,TabActivity1.class)));
mTabHost.addTab(mTabHost.newTabSpec("tab_test3").setIndicator("TAB 3").setContent(new Intent(AndroisTabViewActivity.this,TabActivity1.class)));
mTabHost.setCurrentTab(0);
There is one activity named TabActivity1 which I have also included in Manifest file. 清单文件中也包含一个名为TabActivity1的活动。 But it is showing the error:
但是它显示了错误:
Can't get the activity TabActivity1.
无法获得活动TabActivity1。
I assume you want to show "Tab" at bottom of the window, just try this: 我假设您想在窗口底部显示“制表符”,只需尝试以下操作:
<RelativeLayout
android:layout_width="match_parent"
android:id="@+id/linearLayout1"
android:layout_height="match_parent">
<TabWidget
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@android:id/tabs"
android:layout_alignParentBottom="true">
</TabWidget>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@android:id/tabcontent">
</FrameLayout>
</RelativeLayout>
If you want to use the LinearLayout
: 如果要使用
LinearLayout
:
<?xml version="1.0" encoding="UTF-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</TabHost>
With this solution, the tab content
will take no space firstly, the TabWidget
will take its own space, then the remaining space will be given to the tab content
. 使用此解决方案,
tab content
将首先不占用空间, TabWidget
将占用其自己的空间,然后将剩余空间分配给tab content
。
