我是 Android 的新手，我刚刚创建了我的第一个 TabHost。这是 XML 的代码:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:weightSum="1">
<TextView
style="@style/NormalFont"
android:text="@string/stats"
android:layout_weight="0.10"/>
<TabHost
android:id="@+id/TabHostStats"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ScrollView
android:id="@+id/ScrollViewSmileyFilter"
android:scrollbars="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TableLayout
android:id="@+id/TableLayoutSmileyFilter"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:stretchColumns="*">
</TableLayout>
</ScrollView>
<ScrollView
android:id="@+id/ScrollViewADFilter"
android:scrollbars="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TableLayout
android:id="@+id/TableLayoutADFilter"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:stretchColumns="*">
</TableLayout>
</ScrollView>
</FrameLayout>
</LinearLayout>
</TabHost>
</LinearLayout>
这是 Activity 的代码:
public class StatsActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.stats);
TabHost host = (TabHost) findViewById(R.id.TabHostStats);
host.setup();
/** Dieser Code generiert den Tag für die Smileyfilter Stats**/
TabSpec SmileyFilterTab = host.newTabSpec("sftab");
SmileyFilterTab.setIndicator(getResources().getString(R.string.sfstats));
SmileyFilterTab.setContent(R.id.ScrollViewSmileyFilter);
host.addTab(SmileyFilterTab);
/**Dieser Code generiert den Tag für die Auto Delete Filter Stats **/
TabSpec AutoDeleteTab = host.newTabSpec("adtab");
AutoDeleteTab.setIndicator(getResources().getString(R.string.adstats));
AutoDeleteTab.setContent(R.id.ScrollViewADFilter);
host.addTab(AutoDeleteTab);
}
}
所以我的 TabHosts 的 to 寄存器在最上面。但是我想要他们在按钮上，我该怎么做呢？还有我如何以及在哪里可以更改它们的颜色。我希望它们未被点击时为黑色，如果它们被点击则为蓝色。
最佳答案
我见过很多实现。但我最喜欢这些人。
他有一个 tutorial和可下载的 sample project .
编辑 经过这么多年，这种联系似乎已经断开了。所以这是代码。 这是一个 alternate link为了以防万一，这是代码。
