我有这样的一个TabHost:
I've a TabHost like this:
<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@android:id/tabhost"
android:background="@drawable/tabs_bg">
<LinearLayout
android:id="@+id/LinearLayout01"
android:orientation="vertical"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<TabWidget
android:id="@android:id/tabs"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_marginBottom="5dip">
</TabWidget>
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
</FrameLayout>
</LinearLayout>
和我添加标签来此TabHost编程方式是这样的:
And I am adding tabs to this TabHost programmatically like this:
tabHost = (TabHost)findViewById(android.R.id.tabhost);
tabHost.setOnTabChangedListener(this);
/* tid1 is firstTabSpec Id. Its used to access outside. */
TabSpec firstTabSpec = tabHost.newTabSpec("tid1");
TabSpec secondTabSpec = tabHost.newTabSpec("tid2");
TabSpec ThirdTabSpec = tabHost.newTabSpec("tid3");
/* TabSpec setIndicator() is used to set name for the tab. */
/* TabSpec setContent() is used to set content for a particular tab. */
firstTabSpec.setIndicator("Tab1", getResources().getDrawable(R.drawable.tab1));
secondTabSpec.setIndicator("Tab2", getResources().getDrawable(R.drawable.tab2));
ThirdTabSpec.setIndicator("Tab3", getResources().getDrawable(R.drawable.tab3));
firstTabSpec.setContent(new Intent(this,FirstTab.class));
secondTabSpec.setContent(new Intent(this,SecondTab.class));
ThirdTabSpec.setContent(new Intent(this,ThirdTab.class));
/* Add tabSpec to the TabHost to display. */
tabHost.addTab(firstTabSpec);
tabHost.addTab(secondTabSpec);
tabHost.addTab(ThirdTabSpec);
for(int i=0;i<tabHost.getTabWidget().getChildCount();i++)
{
tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#121312"));
}
tabHost.getTabWidget().setCurrentTab(0);
tabHost.getTabWidget().getChildAt(0).setBackgroundColor(Color.parseColor("#f1a026"));
这里是onTabChanged事件:
And here is onTabChanged Event:
public void onTabChanged(String tabId) {
// TODO Auto-generated method stub
for(int i=0;i<tabHost.getTabWidget().getChildCount();i++)
{
tabHost.getTabWidget().getChildAt(i).setBackgroundColor(Color.parseColor("#121312"));
}
tabHost.getTabWidget().getChildAt(tabHost.getCurrentTab()).setBackgroundColor(Color.parseColor("#f1a026"));
}
在onTabChanged情况下,我也想改变这一切标签的文本颜色。请帮助我,我怎么能更改标签的文本颜色事件?
In onTabChanged event, I also want to change the text color of all tabs. Please help me how can I change text color of tabs in the event?
谢谢
要更改标签的文本颜色,你需要得到它设置为标签标题的观点,即TextView的,你可以这样改变它:
To change the text color of tabs, you need to get the view i.e TextView which is set as title of tabs and you can change it like this:
TabHost tabhost = getTabHost();
for(int i=0;i<tabhost.getTabWidget().getChildCount();i++)
{
TextView tv = (TextView) tabhost.getTabWidget().getChildAt(i).findViewById(android.R.id.title);
tv.setTextColor(.....);
}
希望这有助于....
hope this helps....
