Android的标签式布局setContent [英] Android Tabbed Layout setContent
问题描述
我开发一个Android应用程序与标签布局。我有它的地方它不象产卵谷歌的教程一个新的活动提示，但是我只能这样做是为了让我的内容在每个选项卡上，单击时显示。目前，它只是显示黑色不管是什么标签被激活。
I'm developing an Android application with a tabbed layout. I've got it to where it doesn't spawn a new activity like Google's tutorial suggested, however I only did this in an effort to get my content to show when clicking on each tab. Currently it just shows black regardless of what tab is active.
以下是我的code在其最新的迭代：
The following is my code in its latest iteration:
Main.java
public class Main extends TabActivity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Resources res = getResources();
TabHost tabHost = getTabHost();
TabHost.TabSpec spec;
// add orders tab
spec = tabHost.newTabSpec("orders").setIndicator("Orders",
res.getDrawable(R.drawable.flash_36))
.setContent(R.id.ordersLayout);
tabHost.addTab(spec);
// add positions tab
spec = tabHost.newTabSpec("positions").setIndicator("Positions",
res.getDrawable(R.drawable.small_tiles_36))
.setContent(R.id.positionsLayout);
tabHost.addTab(spec);
// add strategies tab
spec = tabHost.newTabSpec("strategies").setIndicator("Strategies",
res.getDrawable(R.drawable.cards_36))
.setContent(R.id.strategiesLayout);
tabHost.addTab(spec);
// add account tab
spec = tabHost.newTabSpec("account").setIndicator("Account",
res.getDrawable(R.drawable.seal_36))
.setContent(R.id.accountLayout);
tabHost.addTab(spec);
tabHost.setCurrentTab(1);
}
}
的main.xml
<?xml version="1.0" encoding="utf-8"?>
<TabHost android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout android:id="@+id/mainLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp">
<TabWidget android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</TabWidget>
<FrameLayout android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#fff"
android:padding="5dp">
<include layout="@layout/orders"/>
<include layout="@layout/positions"/>
<include layout="@layout/strategies"/>
<include layout="@layout/account"/>
</FrameLayout>
</LinearLayout>
</TabHost>
Account.xml在
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:id="@+id/accountLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#fff"
xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:text="Account Information"
android:id="@+id/accountLabel"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</TextView>
</LinearLayout>
Orders.xml
我只包括这两种，它们都是完全一样的适当IDS的LinearLayout中的android：id参数的
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:id="@+id/ordersLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#fff"
xmlns:android="http://schemas.android.com/apk/res/android">
<TextView
android:text="Working Orders"
android:id="@+id/ordersLabel"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</TextView>
</LinearLayout>
这是一个什么样的选项卡之间切换时，我得到一个截图：
And here's a screenshot of what I get when switching between tabs:
订单标签
位置标签
这是真正为仿真器和三星Galaxy我刚刚和我的方式非常reccommend，任何想法？
This is true for both the emulator and a Samsung Galaxy I just got, and I highly reccommend by the way, any ideas?
推荐答案
我想它了，它的一个简单的参数除了main.xml中的文件：
I figured it out, and it's one simple parameter addition to the main.xml file:
的main.xml（修订）
<?xml version="1.0" encoding="utf-8"?>
<TabHost android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout android:id="@+id/mainLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:padding="5dp">
<TabWidget android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</TabWidget>
<FrameLayout android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#fff"
android:padding="5dp">
<include layout="@layout/orders"/>
<include layout="@layout/positions"/>
<include layout="@layout/strategies"/>
<include layout="@layout/account"/>
</FrameLayout>
</LinearLayout>
</TabHost>
注意在的LinearLayout ，现在包括参数的安卓方向的。这是什么做之前，是推动一切关闭屏幕右侧。现在，它的作品，因为它应该。
Notice the LinearLayout, it now includes the parameter android:orientation. What it was doing before was pushing everything else off screen to the right. Now it works as it should.
注意：在办公室明天我可以测试是否这仍然让我转电话，有它在横向方向正确显示。如果没有，那么我可能会创造一个横向单独的XML文件，除非有人洞察到这门课程。
Note: At the office tomorrow I can test whether this still allows me to rotate the phone and have it display correctly in landscape orientation. If not, then I'll probably have to create a separate xml file for horizontal, unless someone has insights into this of course.
