几天前我也有同样的问题。但是现在有了将其更改为图像的解决方案。默认情况下,选择了第一个选项卡,当“获取”更改时,所有选项卡会根据选项卡选择自动更改。
请参见下面的代码:
public class MainTabActivity extends TabActivity {
TabHost mTabHost;
TabWidget mTabWidget;
private TextView title;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_tab_layout);
//Resources res = getResources();
mTabHost = getTabHost();
TabHost.TabSpec spec;
mTabWidget = mTabHost.getTabWidget();
Intent intent;
intent = new Intent().setClass(MainTabActivity.this, TodaysDealsGroupActivity.class);
spec = mTabHost.newTabSpec(getResources().getString(R.string.tab_todays_deal)).setIndicator(getResources().getString(R.string.tab_todays_deal), getResources().getDrawable(R.drawable.tab_loyalshop_selector)).setContent(intent);
mTabHost.addTab(spec);
intent = new Intent().setClass(MainTabActivity.this, BuddiesGroupActivity.class);
spec = mTabHost.newTabSpec(getResources().getString(R.string.tab_buddies)).setIndicator(getResources().getString(R.string.tab_buddies), getResources().getDrawable(R.drawable.tab_buddies_selector)).setContent(intent);
mTabHost.addTab(spec);
intent = new Intent().setClass(MainTabActivity.this, SearchGroupActivity.class);
spec = mTabHost.newTabSpec(getResources().getString(R.string.tab_search)).setIndicator(getResources().getString(R.string.tab_search), getResources().getDrawable(R.drawable.tab_search_selector)).setContent(intent);
mTabHost.addTab(spec);
intent = new Intent().setClass(MainTabActivity.this, ProfileGroupActivity.class);
spec = mTabHost.newTabSpec(getResources().getString(R.string.tab_profile)).setIndicator(getResources().getString(R.string.tab_profile), getResources().getDrawable(R.drawable.tab_profile_selector)).setContent(intent);
mTabHost.addTab(spec);
intent = new Intent().setClass(MainTabActivity.this, NotificationsGroupActivity.class);
spec = mTabHost.newTabSpec(getResources().getString(R.string.tab_notifications)).setIndicator(getResources().getString(R.string.tab_notifications), getResources().getDrawable(R.drawable.tab_notification_selector)).setContent(intent);
mTabHost.addTab(spec);
for (int i = 0; i < mTabHost.getTabWidget().getChildCount(); i++) {
mTabHost.getTabWidget().getChildAt(i).setBackgroundDrawable(getResources().getDrawable(R.drawable.tab_black_bg));
title = (TextView) mTabWidget.getChildAt(i).findViewById(android.R.id.title);
title.setTextColor(Color.WHITE);
title.setTextSize(10);
}
// check if App starts from the Notification click or not
if(getIntent().hasExtra("notification")){
// for the current tab selection
mTabHost.getTabWidget().getChildAt(4).setBackgroundDrawable(getResources().getDrawable(R.drawable.tab_blue_bg));
mTabHost.setCurrentTab(4);
title = (TextView) mTabWidget.getChildAt(4).findViewById(android.R.id.title);
}else{
// for the current tab selection
mTabHost.getTabWidget().getChildAt(0).setBackgroundDrawable(getResources().getDrawable(R.drawable.tab_blue_bg));
mTabHost.setCurrentTab(0);
title = (TextView) mTabWidget.getChildAt(0).findViewById(android.R.id.title);
}
title.setTextColor(Color.BLACK);
title.setTextSize(10);
// listener for the tab changed
mTabHost.setOnTabChangedListener(new OnTabChangeListener() {
@Override
public void onTabChanged(String tabId) {
for (int i = 0; i < mTabHost.getTabWidget().getChildCount(); i++) {
mTabHost.getTabWidget().getChildAt(i).setBackgroundDrawable(getResources().getDrawable(R.drawable.tab_black_bg));
title = (TextView) mTabWidget.getChildAt(i).findViewById(android.R.id.title);
title.setTextColor(Color.WHITE);
title.setTextSize(10);
}
int tab = mTabHost.getCurrentTab();
mTabHost.getTabWidget().getChildAt(tab).setBackgroundDrawable(getResources().getDrawable(R.drawable.tab_blue_bg));
title = (TextView) mTabWidget.getChildAt(tab).findViewById(android.R.id.title);
title.setTextColor(Color.BLACK);
title.setTextSize(10);
}
});
}
}
这是 XML 文件main_tab_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TabHost
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/tabhost"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:orientation="vertical" >
<FrameLayout
android:id="@android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1" />
<TabWidget
android:id="@android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="bottom|center_horizontal"
android:tabStripEnabled="false" >
</TabWidget>
</LinearLayout>
</TabHost>
</LinearLayout>
只需替换为您的图像并查看结果。
希望这会对你有很大帮助,因为它对我有帮助。
享受编码...
我有三个选项卡和一个自定义分隔线,但是自定义 xml (customtabview.xml) 用于所有五个选项卡。
标签.java
tabHost = getTabHost();
TabHost.TabSpec spec;
LinearLayout v = (LinearLayout)(getLayoutInflater().inflate(R.layout.customtabview, null));
//FIRST TAB
((TextView)v.findViewById(R.id.title)).setText("FIRST");
((TextView)v.findViewById(R.id.title)).setCompoundDrawablesWithIntrinsicBounds(0,R.drawable .tab_back,0,0 );
spec = tabHost.newTabSpec("first").setIndicator(v).setContent(R.id.tab_first_info);
tabHost.addTab(spec);
//SECOND TAB
((TextView)v.findViewById(R.id.title)).setText("SECOND");
((TextView)v.findViewById(R.id.title)).setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.tab_back,0,0 );
spec = tabHost.newTabSpec("second").setIndicator(v).setContent(R.id.tab_second_info);
tabHost.addTab(spec);
//THIRD TAB
((TextView)v.findViewById(R.id.title)).setText("THIRD");
((TextView)v.findViewById(R.id.title)).setCompoundDrawablesWithIntrinsicBounds(0,R.drawable.tab_back,0,0 );
spec = tabHost.newTabSpec("third").setIndicator(v).setContent(R.id.tab_third_info);
tabHost.addTab(spec);
customtabview.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center" >
<TextView
android:id="@+id/title"
android:drawablePadding="4dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>
