联系人存储位置相关问题

1.联系人存储位置
ContactEditorFragment.java
onActivityCreated在account为空时进入selectAccountAndCreateContact方法．
<pre>
private void selectAccountAndCreateContact() {
if (mNewLocalProfile) {
createContact(null);
return;
}
　　//跳转到 ContactEditorAccountsChangedActivity出现选择界面
if (mEditorUtils.shouldShowAccountChangedNotification() &&
!mContext.getResources().getBoolean(R.bool.def_storage_behavior_enabled)) {
Intent intent = new Intent(mContext, ContactEditorAccountsChangedActivity.class);
mStatus = Status.SUB_ACTIVITY;
startActivityForResult(intent, REQUEST_CODE_ACCOUNTS_CHANGED);
} else {
AccountWithDataSet defaultAccount = mEditorUtils.getDefaultAccount();
if (defaultAccount == null) {
createContact(null);
} else {
createContact(defaultAccount);
}
}
}
</pre>
ContactEditorAccountsChangedActivity.java
onCreate方法：
<pre>
　if (numAccounts >= 2) {
setContentView(R.layout.contact_editor_accounts_changed_activity_with_picker);

        final TextView textView = (TextView) findViewById(R.id.text);
        textView.setText(getString(R.string.contact_editor_prompt_multiple_accounts));

        final TextView button = (TextView) findViewById(R.id.add_account_button);
        button.setText(getString(R.string.add_new_account));
        button.setOnClickListener(mAddAccountClickListener);

        final ListView accountListView = (ListView) findViewById(R.id.account_list);

//可选择存储位置
mAccountListAdapter = new AccountsListAdapter(this,
AccountListFilter.ACCOUNTS_CONTACT_WRITABLE);
accountListView.setAdapter(mAccountListAdapter);
accountListView.setOnItemClickListener(mAccountListItemClickListener);
}
</pre>
AccountsListAdapter.java
getView方法：
　　　　　text1.setText(accountType.getDisplayLabel(mContext, account.name));
AccountType.java
getDisplayLabel方法：
<pre>
public CharSequence getDisplayLabel(Context context) {
CharSequence label = null;
updateAuthDescriptions(context);
if (mTypeToAuthDescription.containsKey(accountType)) {
try {
AuthenticatorDescription desc = mTypeToAuthDescription.get(accountType);
　　　　　　　　　　　　　　　 //desc为多个type下的type=com.android.localphone
Context authContext = context.createPackageContext(desc.packageName, 0);
　　　　　　　　　　　　　　　//desc.packageName为com.qualcomm.simcontacts
label = authContext.getResources().getText(desc.labelId);
} catch (PackageManager.NameNotFoundException e) {
Log.w(TAG, "No label name for account type " + accountType);
} catch (Resources.NotFoundException e) {
Log.w(TAG, "No label icon for account type " + accountType);
}
}
return label;
}
</pre>
  因此根据context.createPackageContext(要创建的包名，参数)自身方法，在创建另一个包的上下文，然后通过getResources().getText取其资源；
  在高通项目中，com.qualcomm.simcontacts包名文件所在目录为vendor/qcom/proprietary/trlrphony-apps/simContacts;其中上面log打印出来的type在该目录下
<pre>
res/xml/phone_authenticator.
<account-authenticator xmlns:android="http://schemas.android.com/apk/res/android"
android:accountType="com.android.localphone"
android:icon="@drawable/ic_phone"
android:smallIcon="@drawable/ic_phone"
android:label="@string/account_phone"
/>
</pre>
显示ladbel字串目录为vendor/qcom/proprietary/qrdplus/globalization/multi-language/res-overlay/vendor/qcom/proprietary/telephony-apps/SimContacts/res
2.关于AuthenticatorDescription的学习总结
  联系人数据库中包含有rawContacts数据表，其中accountType以及accountName用于存储账号类型及账号名称。上文中获取的com.android.localphone为所存储的accountType
  其中AuthenticatorDescription用于保存账号类型的描述资源，从而实现国际化的描述。(参考文章：http://m.blog.csdn.net/article/details?id=14447143)
