选中和取消选中时，Android更改选项卡栏文本颜色
我如何更改android标签中的文字颜色，任何人都可以帮助我：
选择标签时，文字颜色为红色，因为您可以看到图像：
当取消选中标签时，文字将为白色，如图中所示：
这是我的Tab_Car_Shop.java类：

这是我的tab_layout.xml文件：

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"

</RelativeLayout>
这是我的tab_home.xml文件：
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- When selected, use this -->
<item android:drawable="@drawable/img_home_up_new"
android:state_selected="true" >
</item>
<!-- When not selected, use that-->
<item android:drawable="@drawable/img_home_new"
android:state_selected="false" />
</selector>
这是我的tab_indicator.xml文件：
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Pressed -->
<item android:state_selected="true" android:state_pressed="true" android:drawable="@drawable/img_bottombar_new" />

</selector>

public void onTabChanged(String tabId) {
// TODO Auto-generated method stub
for(int i=0;i<mTabHost.getTabWidget().getChildCount();i++)
{
View view = mTabHost.getTabWidget().getChildTabViewAt(i);
if ( view != null ) {
// get title text view
TextView textView = (TextView)view. findViewById(R.id.tab_title);
textView.setTextColor(Color.WHITE);
}
}
title.setTextColor(Color.RED);
}
答案 1 :(得分：3)
试试这个
tabHost.setOnTabChangedListener(new TabHost.OnTabChangeListener(){
@Override
public void onTabChanged(String id) {
int tab = tabHost.getCurrentTab();
View v = tabHost.getTabWidget().getChildAt(tab).setBackgroundColor(Color.RED);
}
});
您还可以查看this帖子是否有帮助。
其他替代方案是Actionbar Style generator。您可以指定您的要求，下载zip并在项目中使用。
要更改文字颜色，您可以尝试一下：
TextView tv = (TextView) tabWidget.getChildAt(i).findViewById(android.R.id.title);
tv.setTextColor(Color.RED);
编辑：
您可以使用此逻辑，以便在取消选择标签栏时将颜色更改为白色。
public void onTabChanged(String tabId) {
// TODO Auto-generated method stub
for(int i=0;i<mTabHost.getTabWidget().getChildCount();i++)
{
View view = mTabHost.getTabWidget().getChildTabViewAt(i);
if ( view != null ) {
// get title text view
TextView textView = (TextView) findViewById(R.id.tab_title);
textView.setTextColor(Color.WHITE);
}
}
title.setTextColor(Color.RED);
}
希望这有帮助。
