界面加载过程
DialtactsActivity.java
protected void onCreate(Bundle icicle) {
this.setTheme(R.style.DialtactsTheme);
super.onCreate(icicle);
final Intent intent = getIntent();
fixIntent(intent);
//解析布局文件
DialpadGlobals globals = DialpadGlobals.getGlobals(this);

}
mViewPager.setOffscreenPageLimit(2);
}
//设置滚动页的tab标签属性

Log.d(TAG,"tabHeight="+tabHeight);
getActionBar().setAlternativeTabStyle(true);
getActionBar().setTabHeight(tabHeight);
getActionBar().setLogo(R.mipmap.ic_launcher_contacts);
// Do same width calculation as ActionBar does
DisplayMetrics dm = getResources().getDisplayMetrics();
int minCellSize = getResources().getDimensionPixelSize(R.dimen.fake_menu_button_min_width);
int cellCount = dm.widthPixels / minCellSize;
int fakeMenuItemWidth = dm.widthPixels / cellCount;
if (DEBUG) Log.d(TAG, "The size of fake menu buttons (in pixel): " + fakeMenuItemWidth);
//设置按钮mMenuButton

if (UI.FILTER_CONTACTS_ACTION.equals(intent.getAction()) && icicle == null) {
setupFilterText(intent);
}
if(UniverseUtils.UNIVERSEUI_SUPPORT){
mViewPager.setVisibility(View.VISIBLE);
}
}
1.布局文件解析
在DialtactsActivity的onCreate函数中通过DialpadGlobals加载布局文件，以单例模式获取DialpadGlobals实例对象：
DialpadGlobals.java
public static DialpadGlobals getGlobals(Context context) {
if (INSTANCE == null) {
INSTANCE = new DialpadGlobals(context);
}
return INSTANCE;
}
DialpadGlobals对象的构造过程：
private DialpadGlobals(Context context) {
mContext = context;
mInflater = LayoutInflater.from(context);
Log.d(TAG, "The Optimization do not support UUI.");
initGlobalsTouchLocal();
initGlobalsNotTouchLocal();
try {
Class.forName("com.android.contacts.activities.DialtactsActivity");
Class.forName("com.android.contacts.dialpad.DialpadFragment");
Class.forName("com.android.contacts.calllog.CallLogFragment");
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
IntentFilter filter = new IntentFilter();
filter.addAction(Intent.ACTION_LOCALE_CHANGED);
mContext.registerReceiver(mBroadcast, filter);
}
函数首先加载各个布局文件，然后加载相应的类。
private void initGlobalsTouchLocal() {
Resources resource = mContext.getResources();
mDialpadActivityView = mInflater.inflate(R.layout.dialtacts_activity, null);
mDialpadFragmentView = mInflater.inflate(R.layout.dialpad_list_fragment, null);
mCaLLLogFragmentView = mInflater.inflate(R.layout.call_log_fragment, null);
// pre load DialpadFragment
mCurrentCountryIso = ContactsUtils.getCurrentCountryIso(mContext);
mProhibitedPhoneNumberRegexp = resource.getString(R.string.config_prohibited_phone_number_regexp);
}
这样电话拨号界面就保存在DialpadGlobals类的成员mDialpadActivityView中，通过View view = globals.getDialpadActivityView()就可以得到拨号视图了。
dialtacts_activity.xml布局
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="?android:attr/actionBarSize"
android:id="@+id/dialtacts_frame">
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<ImageButton
android:id="@+id/searchButton"
android:layout_width="wrap_content"
android:layout_height="?android:attr/actionBarSize"
android:layout_gravity="bottom|left"
android:state_enabled="false"
android:background="?android:attr/selectableItemBackground"
android:contentDescription="@string/description_search_button"
android:src="@drawable/ic_dial_action_search"/>
<ImageButton
android:id="@+id/overflow_menu"
android:layout_width="wrap_content"
android:layout_height="?android:attr/actionBarSize"
android:layout_gravity="bottom|right"
android:src="@drawable/ic_menu_overflow"
android:contentDescription="@string/action_menu_overflow_description"
android:nextFocusLeft="@id/digits"
android:background="?android:attr/selectableItemBackground"/>
</FrameLayout>
2.滑动页监听设置
//设置滚动页ViewPages
mViewPager = (ViewPager) findViewById(R.id.pager);
if (mViewPager != null) {
mViewPager.setAdapter(new ViewPagerAdapter(getFragmentManager()));
if (mPageChangeListener != null) {
mViewPager.setOnPageChangeListener(mPageChangeListener);
}
mViewPager.setOffscreenPageLimit(2);
}
滑动适配器
public class ViewPagerAdapter extends FragmentPagerAdapter {
public ViewPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
switch (position) {
//拨号界面
case TAB_INDEX_DIALER_NEWUI:
return new DialpadFragment();
//联系人界面
case TAB_INDEX_CONTACTS_NEWUI:
mAllFragment = new DefaultContactBrowseListFragment();
mAllFragment.mIsDisplayInDialer = true;
return mAllFragment;
//通话记录界面
case TAB_INDEX_CALL_LOG_NEWUI:
return new CallLogFragment();
//收藏界面
case TAB_INDEX_FAVORITES_NEWUI:
return new PhoneFavoriteFragment();
default:
throw new IllegalStateException("No fragment at position " + position);
}
}
@Override
public void setPrimaryItem(ViewGroup container, int position, Object object) {
if (DEBUG) {
Log.d(TAG, "FragmentPagerAdapter#setPrimaryItem(), position: " + position);
}
super.setPrimaryItem(container, position, object);
}
@Override
public int getCount() {
if(UniverseUtils.UNIVERSEUI_SUPPORT){
return TAB_INDEX_COUNT_NEWUI;
} else {
return TAB_INDEX_COUNT;
}
}
}

3.滑动标签设置
setupDialer(); setupCallLog(); setupAllContacts(); setupFavorites();
拨号标签添加
private void setupDialer() {
final Tab tab = getActionBar().newTab();
LayoutInflater inflater = getLayoutInflater();
View view = inflater.inflate(R.layout.dialtacts_tab_new_ui, null);
ImageView dialView = (ImageView)view.findViewById(R.id.tab_icon);
if(dialView != null){
dialView.setImageResource(R.drawable.ic_tab_dialer_newui);
}
TextView dialText = (TextView) view.findViewById(R.id.tab_text);
if(dialText!=null){
dialText.setText(R.string.dialerIconLabel);
}
tab.setCustomView(view);
tab.setTabListener(mTabListener);
getActionBar().addTab(tab);
}
通话记录标签添加
private void setupCallLog() {
final Tab tab = getActionBar().newTab();
LayoutInflater inflater = getLayoutInflater();
View view = inflater.inflate(R.layout.dialtacts_tab_new_ui, null);
ImageView dialView = (ImageView)view.findViewById(R.id.tab_icon);
if(dialView != null){
dialView.setImageResource(R.drawable.ic_tab_recent_newui);
}
TextView dialText = (TextView) view.findViewById(R.id.tab_text);
if(dialText!=null){
dialText.setText(R.string.recentCallsIconLabel);
}
tab.setCustomView(view);
tab.setTabListener(mTabListener);
getActionBar().addTab(tab);
}
收藏标签添加
private void setupFavorites() {
final Tab tab = getActionBar().newTab();
LayoutInflater inflater = getLayoutInflater();
View view = inflater.inflate(R.layout.dialtacts_tab_new_ui, null);
ImageView dialView = (ImageView)view.findViewById(R.id.tab_icon);
if(dialView != null){
dialView.setImageResource(R.drawable.ic_tab_starred_newui);
}
TextView dialText = (TextView) view.findViewById(R.id.tab_text);
if(dialText!=null){
dialText.setText(R.string.contactsFavoritesLabel);
}
tab.setCustomView(view);
tab.setTabListener(mTabListener);
getActionBar().addTab(tab);
}
联系人标签添加
private void setupAllContacts() {
final Tab tab = getActionBar().newTab();
LayoutInflater inflater = getLayoutInflater();
View view = inflater.inflate(R.layout.dialtacts_tab_new_ui, null);
ImageView dialView = (ImageView)view.findViewById(R.id.tab_icon);
if(dialView != null){
dialView.setImageResource(R.drawable.ic_tab_all_newui);
}
TextView dialText = (TextView) view.findViewById(R.id.tab_text);
if(dialText!=null){
dialText.setText(R.string.people);
}
tab.setCustomView(view);
tab.setTabListener(mTabListener);
getActionBar().addTab(tab);
}
拨号界面
拨号视图加载过程：
DialpadFragment.java
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedState) {
//调用父类DialMatchFragment的onCreateView
View fragmentView = super.onCreateView(inflater ,container ,savedState);
// Load up the resources for the text field.
Resources r = getResources();
mAdditionalButtonsRow = fragmentView.findViewById(R.id.dialpadAdditionalButtons);
mDialpad = fragmentView.findViewById(R.id.dialpad_container); // This is null in landscape mode.
mDigitsContainer = fragmentView.findViewById(R.id.digits_container);
mDigits = (EditText) fragmentView.findViewById(R.id.digits);
if(mDigits != null){
mDigits.setSingleLine();
mDigits.setKeyListener(DialerKeyListener.getInstance());
mDigits.setOnClickListener(this);
mDigits.setOnKeyListener(this);
mDigits.setOnLongClickListener(this);
mDigits.addTextChangedListener(this);
}
...
return fragmentView;
}
父类DialMatchFragment的onCreateView函数实现
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
mView = inflateView(inflater, container);
mListView = (ListView) mView.findViewById(android.R.id.list);
if (mListView == null) {
throw new RuntimeException(
"Your content must have a ListView whose id attribute is android.R.id.list'");
}
View emptyView = mView.findViewById(com.android.internal.R.id.empty);
if (emptyView != null) {
mListView.setEmptyView(emptyView);
if (emptyView instanceof ContactListEmptyView) {
mEmptyView = (ContactListEmptyView) emptyView;
}
}
...
return mView;
}
调用该类的inflateView函数来加载布局，该函数在DialMatchFragment的子类中实现
DialpadFragment.java
protected View inflateView(LayoutInflater inflater, ViewGroup container) {
DialpadGlobals globals = DialpadGlobals.getGlobals(getActivity());
View view = globals.getDialpadFragmentView();
if (view != null) {
Log.d(TAG, "get view from application");
return view;
} else {
return inflater.inflate(R.layout.dialpad_list_fragment, null);
}
}
