前言
android拨号盘的源码目录在package/app/Dialer
自7.0以后Incallui的源码直接放到了Dialer目录下，虽然在7.0以前incallui有自己独立的目录，但实际编译过程中只是作为链接库最后还是被编译到Dialer的apk里
博主这里只取Dialer相关的源码并导入AS中，并稍作调整兼容至L
源码目录结构如下：
先理一理各个工程的依赖关系
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

1.1拨号盘概览
先来看看几张原图
1.2 DialtactsActivity
主activity为DialtactsActivity
com.android.dialer.DialtactsActivity
public class DialtactsActivity extends TransactionSafeActivity 。。。{ // Fragment containing the dialpad that slides into view
protected 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; ...... ......
...... .....
}
如类图关系所示，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（部分内容省略）
@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ActionBarController
mActionBarController = 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ListsFragment
getFragmentManager().beginTransaction()
.add(R.id.dialtacts_frame, new ListsFragment(), TAG_FAVORITES_FRAGMENT)
.commit(); // 初始化单例对象DialerDatabaseHelper
mDialerDatabaseHelper = DatabaseHelperManager.getDatabaseHelper(this);
SmartDialPrefix.initializeNanpSettings(this); }
1.3 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HorizontalScrollView
private 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fragment
private SpeedDialFragment mSpeedDialFragment;
// 最近通话记录fragment
private CallLogFragment mHistoryFragment;
// 联系人列表fragment
private AllContactsFragment mAllContactsFragment;
// Voicemail列表fragment
private CallLogFragment mVoicemailFragment;
@Override
public 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
SpeedDialFragment显示常用联系人列表
public class SpeedDialFragment extends Fragment ...{
// 显示数据的GridView列表
private PhoneFavoriteListView mListView;
// 源数据BaseAdapter
private PhoneFavoritesTileAdapter mContactTileAdapter;
// 查询源数据的LoaderCallbacks
private class ContactTileLoaderListener implements LoaderManager.LoaderCallbacks<Cursor> {
@Override
public CursorLoader onCreateLoader(int id, Bundle args) {
if (DEBUG) Log.d(TAG, "ContactTileLoaderListener#onCreateLoader.");
return ContactTileLoaderFactory.createStrequentPhoneOnlyLoader(getActivity());
}
@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor data) {
if (DEBUG) Log.d(TAG, "ContactTileLoaderListener#onLoadFinished");
mContactTileAdapter.setContactCursor(data);
setEmptyViewVisibility(mContactTileAdapter.getCount() == 0);
}
@Override
public void onLoaderReset(Loader<Cursor> loader) {
if (DEBUG) Log.d(TAG, "ContactTileLoaderListener#onLoaderReset. ");
}
}
}使用LoadManager方式获取cursor数据，查询ContactsProvider数据库的data表
com.android.contacts.common.ContactTileLoaderFactory
public static CursorLoader createStrequentPhoneOnlyLoader(Context context) {
Uri uri = Contacts.CONTENT_STREQUENT_URI.buildUpon()
.appendQueryParameter(ContactsContract.STREQUENT_PHONE_ONLY, "true").build(); return new CursorLoader(context, uri, COLUMNS_PHONE_ONLY, null, null, null);
}
数据来源包括收藏的联系人以及有通话记录的联系人
1.4 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
@Override
public 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 keypad
View 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();
}
}
}当处于通话状态时显示如下
1.5SmartDialSearchFragment 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{
@Override
protected 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;
}
@Override
public 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{
@Override
protected 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adapter
private 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Loader
public 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
1.6小结
