将联系人从手机导入到我在 android 的应用程序中的列表 [重复]

Question

在我的应用中，我想让用户显示他们手机中的联系人。我用这个example 从应用程序中打开我的手机通讯录。但是现在我想通过复制手机中的所有联系人来在我的应用程序中列出联系人列表。最好的方法是什么？

编辑：

我已经知道如何显示联系人，但我不知道如何将它们保存到 sqlite db。我是一个初学者，所以任何帮助表示赞赏。

Answer 1

试试这个对我有用的例子。

首先，您需要在 mainifest 文件中设置权限。您的 Mainifest 文件应如下所示。

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="in.wptrafficanalzer.listviewcontacts"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="5"
    android:targetSdkVersion="15" />

<uses-permission 
    android:name="android.permission.READ_CONTACTS" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/title_activity_main" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

完成此操作后，您需要在布局文件夹中创建两个 XML 文件。

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<ListView
    android:id="@+id/lst_contacts"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
     />

</RelativeLayout>

lv_layout.xml

<?xml version="1.0" encoding="utf-8"?>

<TextView 
    android:id="@+id/tv_name"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"        
    android:textSize="20dp"   
    android:textStyle="bold" />

<ImageView 
    android:id="@+id/iv_photo"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@id/tv_name"
    android:layout_centerHorizontal="true"
    android:padding="5dp" />

<TextView 
    android:id="@+id/tv_details"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@id/iv_photo"        
      />

</RelativeLayout>

创建布局文件后，您的 MainActivity 类将如下所示。

MainActivity.Java

public class MainActivity extends Activity {

SimpleCursorAdapter mAdapter;
MatrixCursor mMatrixCursor;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // The contacts from the contacts content provider is stored in this
    // cursor
    mMatrixCursor = new MatrixCursor(new String[] { "_id", "name", "photo",
            "details" });

    // Adapter to set data in the listview
    mAdapter = new SimpleCursorAdapter(getBaseContext(),
            R.layout.lv_layout, null, new String[] { "name", "photo",
                    "details" }, new int[] { R.id.tv_name, R.id.iv_photo,
                    R.id.tv_details }, 0);

    // Getting reference to listview
    ListView lstContacts = (ListView) findViewById(R.id.lst_contacts);

    // Setting the adapter to listview
    lstContacts.setAdapter(mAdapter);

    // Creating an AsyncTask object to retrieve and load listview with
    // contacts
    ListViewContactsLoader listViewContactsLoader = new ListViewContactsLoader();

    // Starting the AsyncTask process to retrieve and load listview with
    // contacts
    listViewContactsLoader.execute();

}

/** An AsyncTask class to retrieve and load listview with contacts */
private class ListViewContactsLoader extends AsyncTask<Void, Void, Cursor> {

    @Override
    protected Cursor doInBackground(Void... params) {
        Uri contactsUri = ContactsContract.Contacts.CONTENT_URI;

        // Querying the table ContactsContract.Contacts to retrieve all the
        // contacts
        Cursor contactsCursor = getContentResolver().query(contactsUri,
                null, null, null,
                ContactsContract.Contacts.DISPLAY_NAME + " ASC ");

        if (contactsCursor.moveToFirst()) {
            do {
                long contactId = contactsCursor.getLong(contactsCursor
                        .getColumnIndex("_ID"));

                Uri dataUri = ContactsContract.Data.CONTENT_URI;

                // Querying the table ContactsContract.Data to retrieve
                // individual items like
                // home phone, mobile phone, work email etc corresponding to
                // each contact
                Cursor dataCursor = getContentResolver().query(dataUri,
                        null,
                        ContactsContract.Data.CONTACT_ID + "=" + contactId,
                        null, null);

                String displayName = "";
                String nickName = "";
                String homePhone = "";
                String mobilePhone = "";
                String workPhone = "";

                String homeEmail = "";
                String workEmail = "";

                if (dataCursor.moveToFirst()) {

Answer 2

你可以这样做：

添加功能：

private List<Person> getContactList(){
        ArrayList<Person> contactList = new ArrayList<Person>();

        Uri contactUri = ContactsContract.Contacts.CONTENT_URI;
        String[] PROJECTION = new String[] {
                ContactsContract.Contacts._ID,
                ContactsContract.Contacts.DISPLAY_NAME,
                ContactsContract.Contacts.HAS_PHONE_NUMBER,
        };
        String SELECTION = ContactsContract.Contacts.HAS_PHONE_NUMBER + "='1'";
        Cursor contacts = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, PROJECTION, SELECTION, null, null);


        if (contacts.getCount() > 0)
        {
            while(contacts.moveToNext()) {
                Person aContact = new Person();
                int idFieldColumnIndex = 0;
                int nameFieldColumnIndex = 0;
                int numberFieldColumnIndex = 0;

                String contactId = contacts.getString(contacts.getColumnIndex(ContactsContract.Contacts._ID));

                nameFieldColumnIndex = contacts.getColumnIndex(PhoneLookup.DISPLAY_NAME);
                if (nameFieldColumnIndex > -1)
                {
                    aContact.setName(contacts.getString(nameFieldColumnIndex));
                }

                PROJECTION = new String[] {Phone.NUMBER};
                final Cursor phone = managedQuery(Phone.CONTENT_URI, PROJECTION, Data.CONTACT_ID + "=?", new String[]{String.valueOf(contactId)}, null);
                if(phone.moveToFirst()) {
                    while(!phone.isAfterLast())
                    {
                        numberFieldColumnIndex = phone.getColumnIndex(Phone.NUMBER);
                        if (numberFieldColumnIndex > -1)
                        {
                            aContact.setPhoneNum(phone.getString(numberFieldColumnIndex));
