拨号盘概览

先来看看几张原图

工程依赖关系

com.android.dialer是主工程依赖于

com.android.contacts.common工程和com.android.phone.common工程

com.android.contacts.common又依赖于

com.android.phone.common工程和com.android.common工程

另外一些support包也作为链接工程被引入，以上代码均取自google源码

关键类

DialtactsActivity

com.android.dialer.DialtactsActivity
public class DialtactsActivity extends TransactionSafeActivity 。。。{// Fragment containing the dialpad that slides into viewprotected DialpadFragment mDialpadFragment;// Fragment for searching phone numbers using the alphanumeric keyboard.private RegularSearchFragment mRegularSearchFragment;// Fragment for searching phone numbers using the dialpad.private SmartDialSearchFragment mSmartDialSearchFragment;// Fragment containing the speed dial list, call history list, and all contacts list.    private ListsFragment mListsFragment;private DialerDatabaseHelper mDialerDatabaseHelper;private FloatingActionButtonController mFloatingActionButtonController;...... ............ .....}

主要有以下几个关键的成员变量

com.android.dialer.dialpad .DialpadFragment // 拨号盘fragment

com.android.dialer.list.RegularSearchFragment // 联系人搜索fragment

com.android.dialer.list.SmartDialSearchFragment // 拨号搜索fragment

com.android.dialer.list.ListsFragment // TAB页fragment，包含快速联系人，最近通话记录，联系人列表三个子fragment

com.android.dialer.database.DialerDatabaseHelper // 拨号搜索数据库SQLiteOpenHelper对象

com.android.contacts.common.widget.FloatingActionButtonController // 悬浮按钮控制器

再看看onCreate里的主要实现

@Override
protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.dialtacts_activity);final ActionBar actionBar = getSupportActionBar();actionBar.setCustomView(R.layout.search_edittext);// 给actionbar设置自定义view （SearchEditTextLayout）SearchEditTextLayout searchEditTextLayout = (SearchEditTextLayout) actionBar.getCustomView().findViewById(R.id.search_view_container);// 给SearchEditTextLayout添加管理器ActionBarControllermActionBarController = new ActionBarController(this, searchEditTextLayout);final View floatingActionButtonContainer = findViewById(R.id.floating_action_button_container);ImageButton floatingActionButton = (ImageButton) findViewById(R.id.floating_action_button);floatingActionButton.setOnClickListener(this);// 用FloatingActionButtonController管理悬浮按钮mFloatingActionButtonController = new FloatingActionButtonController(this,floatingActionButtonContainer, floatingActionButton);// 添加ListsFragmentgetFragmentManager().beginTransaction().add(R.id.dialtacts_frame, new ListsFragment(), TAG_FAVORITES_FRAGMENT).commit();// 初始化单例对象DialerDatabaseHelpermDialerDatabaseHelper = DatabaseHelperManager.getDatabaseHelper(this);SmartDialPrefix.initializeNanpSettings(this);}

ListsFragment

ListsFragment是主fragment，结构如下：

public class ListsFragment extends Fragment{private ViewPager mViewPager;private ViewPagerTabs mViewPagerTabs;  // 自定义TAB标签，继承自HorizontalScrollViewprivate ViewPagerAdapter mViewPagerAdapter;// 拖拽常用联系人时悬浮视图private RemoveView mRemoveView;private View mRemoveViewContent;// 常用联系人fragmentprivate SpeedDialFragment mSpeedDialFragment;// 最近通话记录fragmentprivate CallLogFragment mHistoryFragment;// 联系人列表fragmentprivate AllContactsFragment mAllContactsFragment;// Voicemail列表fragmentprivate CallLogFragment mVoicemailFragment;@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {final View parentView = inflater.inflate(R.layout.lists_fragment, container, false);mViewPager = (ViewPager) parentView.findViewById(R.id.lists_pager);mViewPagerAdapter = new ViewPagerAdapter(getChildFragmentManager());mViewPager.setAdapter(mViewPagerAdapter);mViewPager.setOffscreenPageLimit(TAB_COUNT_WITH_VOICEMAIL - 1);mViewPager.setOnPageChangeListener(this);showTab(TAB_INDEX_SPEED_DIAL);...... ......  ...... ......mViewPagerTabs = (ViewPagerTabs) parentView.findViewById(R.id.lists_pager_header);mViewPagerTabs.configureTabIcons(mTabIcons);mViewPagerTabs.setViewPager(mViewPager);addOnPageChangeListener(mViewPagerTabs);mRemoveView = (RemoveView) parentView.findViewById(R.id.remove_view);mRemoveViewContent = parentView.findViewById(R.id.remove_view_content);return parentView;}
}

ListsFragment最多可以显示四个fragment，有个VisualVoicemailCallLogFragment显示一种特定的通话记录（提供视频语音邮件服务）

类型为Calls.VOICEMAIL_TYPE，需要运营商支持，只有存在该类通话记录才会显示该TAB页，国内运营商暂不支持

OldSpeedDialFragment显示常用联系人列表

// 查询源数据的LoaderCallbacks
private static final class ContactTileLoaderListenerimplements LoaderManager.LoaderCallbacks<Cursor> {private final OldSpeedDialFragment fragment;// 源数据BaseAdapterprivate final PhoneFavoritesTileAdapter adapter;ContactTileLoaderListener(OldSpeedDialFragment fragment, PhoneFavoritesTileAdapter adapter) {this.fragment = fragment;this.adapter = adapter;}@Overridepublic CursorLoader onCreateLoader(int id, Bundle args) {return ContactTileLoaderFactory.createStrequentPhoneOnlyLoader(fragment.getContext());}@Overridepublic void onLoadFinished(Loader<Cursor> loader, Cursor data) {adapter.setContactCursor(data);fragment.setEmptyViewVisibility(adapter.getCount() == 0);FragmentUtils.getParentUnsafe(fragment, HostInterface.class).setHasFrequents(adapter.getNumFrequents() > 0);}@Overridepublic void onLoaderReset(Loader<Cursor> loader) {}}

DialpadFragment

DialpadFragment显示拨号盘fragment

在DialtactsActivity中添加如下

private void showDialpadFragment(boolean animate) {if (mDialpadFragment == null) {mDialpadFragment = new DialpadFragment();ft.add(R.id.dialtacts_container, mDialpadFragment, TAG_DIALPAD_FRAGMENT);} else {ft.show(mDialpadFragment);}}

第一次显示时动态添加进去，后续动态控制显示隐藏

public class DialpadFragment extends Fragment{private DialpadView mDialpadView; // 拨号数字面板（包括输入号码框）private EditText mDigits;          // 输入号码框private ToneGenerator mToneGenerator; // DTMF音播放器private ListView mDialpadChooser;     // 通话状态时显示的视图private DialpadChooserAdapter mDialpadChooserAdapter;// 通话状态时显示的视图adapter@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedState) {// 横竖屏加载不同的布局final View fragmentView = inflater.inflate(R.layout.dialpad_fragment, container,false);fragmentView.buildLayer();mDialpadView = (DialpadView) fragmentView.findViewById(R.id.dialpad_view);mDialpadView.setCanDigitsBeEdited(true);mDigits = mDialpadView.getDigits();...... ........... ......PhoneNumberFormatter.setPhoneNumberFormattingTextWatcher(getActivity(), mDigits);  // 格式化输入框中的号码// Check for the presence of the keypadView oneButton = fragmentView.findViewById(R.id.one);if (oneButton != null) {  // 绑定各个数字按键onPress事件configureKeypadListeners(fragmentView);}...... ............ ......mDialpadChooser = (ListView) fragmentView.findViewById(R.id.dialpadChooser);mDialpadChooser.setOnItemClickListener(this);...... ..... ...... ......return fragmentView;}}

横屏和竖屏所加载的拨号面板布局是不一样的

DialpadView是个自定义视图，主要用于显示数字按键和输入号码框

public class DialpadView extends LinearLayout {private EditText mDigits;     // 输入号码框private ImageButton mDelete; // 删除按钮private void setupKeypad() {...... ............ ......DialpadKeyButton dialpadKey;TextView numberView;TextView lettersView;...... ............ ......for (int i = 0; i < mButtonIds.length; i++) {dialpadKey = (DialpadKeyButton) findViewById(mButtonIds[i]);numberView = (TextView) dialpadKey.findViewById(R.id.dialpad_key_number);lettersView = (TextView) dialpadKey.findViewById(R.id.dialpad_key_letters);...... ............ ......final RippleDrawable rippleBackground = (RippleDrawable)getDrawableCompat(getContext(), R.drawable.btn_dialpad_key);if (mRippleColor != null) {rippleBackground.setColor(mRippleColor);            }numberView.setText(numberString);numberView.setElegantTextHeight(false);dialpadKey.setContentDescription(numberContentDescription);dialpadKey.setBackground(rippleBackground); // 设置数字按键水波纹背景色if (lettersView != null) {lettersView.setText(resources.getString(letterIds[i]));}}...... ............ ......}

public void animateShow() {  // 显示拨号面板时各个数字按键的动画效果...... ............ ......for (int i = 0; i < mButtonIds.length; i++) {...... ............ ......ViewPropertyAnimator animator = dialpadKey.animate();if (mIsLandscape) {// Landscape orientation requires translation along the X axis.// For RTL locales, ensure we translate negative on the X axis.dialpadKey.setTranslationX((mIsRtl ? -1 : 1) * mTranslateDistance);animator.translationX(0);} else {// Portrait orientation requires translation along the Y axis.dialpadKey.setTranslationY(mTranslateDistance);animator.translationY(0);}animator.setInterpolator(AnimUtils.EASE_OUT_EASE_IN).setStartDelay(delay).setDuration(duration).setListener(showListener).start();}}
}

SmartDialSearchFragment RegularSearchFragment

SmartDialSearchFragment显示拨号搜索结果fragment（在拨号面板输入数字时显示）

RegularSearchFragment显示联系人搜索结果fragment（在actionbar输入框输入字符时显示）

在DialtactsActivity中进入或退出搜索模式时动态添加移除

private void enterSearchUi(boolean smartDialSearch, String query, boolean animate) {...... ............ ......if (fragment == null) {if (smartDialSearch) {fragment = new SmartDialSearchFragment();} else {fragment = ObjectFactory.newRegularSearchFragment();...... ............ ......}transaction.add(R.id.dialtacts_frame, fragment, tag);} else {transaction.show(fragment);}...... ............ ......}private void exitSearchUi() {...... ............ ......final FragmentTransaction transaction = getFragmentManager().beginTransaction();if (mSmartDialSearchFragment != null) {transaction.remove(mSmartDialSearchFragment);}if (mRegularSearchFragment != null) {transaction.remove(mRegularSearchFragment);}transaction.commit();mListsFragment.getView().animate().alpha(1).withLayer();...... ............ ......mActionBarController.onSearchUiExited();}

拨号搜素只能通过拨号面板的输入数字，支持T9搜索，但是原生不支持拼音检索

public class SmartDialSearchFragment extends SearchFragment{@Overrideprotected ContactEntryListAdapter createListAdapter() {SmartDialNumberListAdapter adapter = new SmartDialNumberListAdapter(getActivity());adapter.setUseCallableUri(super.usesCallableUri());adapter.setQuickContactEnabled(true);// Set adapter's query string to restore previous instance state.adapter.setQueryString(getQueryString());adapter.setListener(this);return adapter;}@Overridepublic Loader<Cursor> onCreateLoader(int id, Bundle args) {// Smart dialing does not support Directory Load, falls back to normal search instead.if (id == getDirectoryLoaderId()) {return super.onCreateLoader(id, args);} else {final SmartDialNumberListAdapter adapter = (SmartDialNumberListAdapter) getAdapter();SmartDialCursorLoader loader = new SmartDialCursorLoader(super.getContext());adapter.configureLoader(loader);return loader;}}
}

联系人搜索则通过软键盘输入，不过不支持T9搜索

public class RegularSearchFragment extends SearchFragment{@Overrideprotected ContactEntryListAdapter createListAdapter() {RegularSearchListAdapter adapter = new RegularSearchListAdapter(getActivity());adapter.setDisplayPhotos(true);adapter.setUseCallableUri(usesCallableUri());adapter.setListener(this);return adapter;}
}

从类关系图上可以得知两个fragment和对应的adapter都继承于同一个父类，最终都派生自ContactsCommon工程里的模板类ContactEntryListFragment

public abstract class ContactEntryListFragment<T extends ContactEntryListAdapter>extends Fragment{private T mAdapter;          // 模板adapterprivate View mView;private ListView mListView;private ContactPhotoManager mPhotoManager;  // 头像管理protected abstract View inflateView(LayoutInflater inflater, ViewGroup container);protected abstract T createListAdapter();        // 子类中实现具体adapter@Override   // 子类可重写获取数据的Loaderpublic Loader<Cursor> onCreateLoader(int id, Bundle args) { if (id == DIRECTORY_LOADER_ID) {DirectoryListLoader loader = new DirectoryListLoader(mContext);loader.setDirectorySearchMode(mAdapter.getDirectorySearchMode());loader.setLocalInvisibleDirectoryEnabled(ContactEntryListAdapter.LOCAL_INVISIBLE_DIRECTORY_ENABLED);return loader;} else {CursorLoader loader = createCursorLoader(mContext);long directoryId = args != null && args.containsKey(DIRECTORY_ID_ARG_KEY)? args.getLong(DIRECTORY_ID_ARG_KEY): Directory.DEFAULT;mAdapter.configureLoader(loader, directoryId);return loader;}}}

ContactEntryListFragment内部封装了很多操作，绑定了ContactEntryListAdapter，具体细节就不在这里详述了。
最后附上Dialer主要类图：
