我想在点击 tabhost 时更改图标
下面是源码
private void setTabs() {
addTab("Home", TabHome.class, R.drawable.home);
addTab("Performers", TabPerformers.class, R.drawable.performers);
addTab("Tickets", TabTickets.class, R.drawable.tickets);
addTab("Info", TabInfo.class, R.drawable.info);
}
private void addTab(String labelId, Class<?> c, int drawableId) {
tabHost = getTabHost();
Intent intent = new Intent(this, c);
TabHost.TabSpec spec = tabHost.newTabSpec("tab" + labelId);
tabIndicator = LayoutInflater.from(this).inflate(R.layout.tab_indicator, getTabWidget(), false);
icon = (ImageView) tabIndicator.findViewById(R.id.icon);
icon.setImageResource(drawableId);
spec.setIndicator(tabIndicator);
spec.setContent(intent);
tabHost.addTab(spec);
}
当用户按下我在 tabhost 事件下面使用的选项卡时,我想更改选项卡的图标
tabHost.setOnTabChangedListener(new OnTabChangeListener() {
@Override
public void onTabChanged(String tabId) {
if (tabId.equals("tabHome")) {
但未能成功
还有一个 tab_indicater.xml 文件,但只有背景会发生变化,而不是图标
下面是xml代码
<?xml version="1.0" encoding="utf-8"?>
<!-- Non focused states -->
<item android:drawable="@drawable/tab_unselected" android:state_focused="false" android:state_pressed="false" android:state_selected="false"/>
<item android:drawable="@drawable/tab_bg_selector" android:state_focused="false" android:state_pressed="false" android:state_selected="true"/>
<!-- Focused states -->
<item android:drawable="@drawable/tab_bg_selector" android:state_focused="true" android:state_pressed="false" android:state_selected="false"/>
<item android:drawable="@drawable/tab_bg_selector" android:state_focused="true" android:state_pressed="false" android:state_selected="true"/>
<!-- Pressed -->
<item android:drawable="@drawable/tab_bg_selector" android:state_pressed="true" android:state_selected="true"/>
<item android:drawable="@drawable/tab_press" android:state_pressed="true"/>
下面是屏幕截图
当我们点击任何一个选项卡时,它的图标应该发生变化,就像这里它必须变成橙色..
任何人都可以帮助我吗...
最佳答案
没有直接的方法来更改 TabSpec 图标。您必须将图标放入选择器可绘制对象中。
