我正在尝试在Android中创建自定义标签,我已将标签创建为FragmentActivity
和FragmentPagerAdapter
这是代码,但我真的不知道在哪里使用
来扩充自定义标签View tabIndicator = LayoutInflater.from(mContext).
inflate(R.layout.tab_item, mTabHost.getTabWidget(), false);
FragmentActivity的onCreate方法中的代码
mTabHost = (TabHost)findViewById(android.R.id.tabhost);
mTabHost.setup();
if(mTabHost!=null) System.out.println("***ITS NOT NULL****");
mViewPager = (ViewPager)findViewById(R.id.pager);
mTabsAdapter = new TabsAdapter(this, mTabHost, mViewPager);
mTabsAdapter.addTab(mTabHost.newTabSpec("simple").setIndicator("Contacts"),
ContactSummaryFragment.class, null);
mTabsAdapter.addTab(mTabHost.newTabSpec("custom").setIndicator("Template"),
TextVoiceTemplate.class, null);
addTab方法
public void addTab(TabHost.TabSpec tabSpec, Class<?> clss, Bundle args) {
tabSpec.setContent(new DummyTabFactory(mContext));
// I got to place this line somewhere here i guess
//View tabIndicator = LayoutInflater.from(mContext).inflate(R.layout.tab_item, mTabHost.getTabWidget(), false);
String tag = tabSpec.getTag();
TabInfo info = new TabInfo(tag, clss, args);
mTabs.add(info);
mTabHost.addTab(tabSpec);
notifyDataSetChanged();
}
答案 0 :(得分:3)
您可以使用tabSpec指定布局:
您的适配器中有addTab
public void addTab(TabHost.TabSpec tabSpec, Class<?> clss, Bundle args)
{
tabSpec.setContent(new DummyTabFactory(mContext));
String tag = tabSpec.getTag();
TabInfo info = new TabInfo(tag, clss, args);
mTabs.add(info);
mTabHost.addTab(tabSpec);
notifyDataSetChanged();
}
在您用内容填充标签之前(通常在onCreate中),您可以编写自己的功能
private static View prepareTabView(Context context, String text, int drawable)
{
View view = LayoutInflater.from(context).inflate(R.layout.tab_layout, null);
((TextView) view.findViewById(R.id.tabTitle)).setText(text);
((ImageView) view.findViewById(R.id.tabImage)).setImageResource(drawable);
return view;
}
public static void addTab(TabsAdapter adapter, TabHost host, String title, String tag, int drawable, Class cl)
{
TabHost.TabSpec spec = host.newTabSpec(tag);
View view = prepareTabView(host.getContext(), title, drawable);
spec.setIndicator(view);
adapter.addTab(spec, cl,null);
}
现在您可以使用自己的addTab填充tabHost,它在适配器中使用addTab:
mTabHost = (TabHost) findViewById(android.R.id.tabhost);
mTabHost.setup();
mViewPager = (ViewPager) findViewById(R.id.pager);
mTabsAdapter = new TabsAdapter(this, mTabHost, mViewPager, getSupportFragmentManager());
addTab(mTabsAdapter, mTabHost, getString(R.string.title1), CONST, R.drawable.tab_drawable1, Fragment1.class);
addTab(mTabsAdapter, mTabHost, getString(R.string.title1), CONST2, R.drawable.tab_formula_image_selector, Fragment2.class);
在这个例子中你有R.layout.tab_layout,有drawable,background,text等......:
R.layout.tab_layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="top" android:background="@drawable/tabbg">
<TextView
android:id="@+id/tabTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginBottom="30dp"
android:text="TextView"
android:textColor="@color/tabtextcolor"
android:textSize="12sp" android:layout_alignParentBottom="true"/>
<ImageView
android:id="@+id/tabImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="5dp" android:layout_above="@id/tabTitle" android:layout_centerHorizontal="true"/>
</RelativeLayout>
通过这个例子,你会得到像这样的东西:
