如何以编程方式链接联系人号码

Question

我想使用Contacts开发具有基本CRUD操作的联系人应用程序，并使用Android主要链接联系人号码。

Answer 1

试试这个，它对我有效：

public class MyActivity extends Activity {
private static final String TAG = MyActivity.class.getSimpleName();
private static final int REQUEST_CODE_PICK_CONTACTS = 1;
private Uri uriContact;
private String contactID;     // contacts unique ID

/**
* Called when the activity is first created.
*/
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public void onClickSelectContact(View btnSelectContact) {
// using native contacts selection
// Intent.ACTION_PICK = Pick an item from the data, returning what was selected.
startActivityForResult(new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI), REQUEST_CODE_PICK_CONTACTS);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_CODE_PICK_CONTACTS && resultCode == RESULT_OK) {
Log.d(TAG, "Response: " + data.toString());
uriContact = data.getData();
retrieveContactName();
retrieveContactNumber();
retrieveContactPhoto();
}
}
private void retrieveContactPhoto() {
Bitmap photo = null;
try {
InputStream inputStream = ContactsContract.Contacts.openContactPhotoInputStream(getContentResolver(),
ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, new Long(contactID)));
if (inputStream != null) {
photo = BitmapFactory.decodeStream(inputStream);
ImageView imageView = (ImageView) findViewById(R.id.img_contact);
imageView.setImageBitmap(photo);
}
assert inputStream != null;
inputStream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
private void retrieveContactNumber() {
String contactNumber = null;
// getting contacts ID
Cursor cursorID = getContentResolver().query(uriContact,
new String[]{ContactsContract.Contacts._ID},
null, null, null);
if (cursorID.moveToFirst()) {
contactID = cursorID.getString(cursorID.getColumnIndex(ContactsContract.Contacts._ID));
}
cursorID.close();
Log.d(TAG, "Contact ID: " + contactID);
// Using the contact ID now we will get contact phone number
Cursor cursorPhone = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER},
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ? AND " +
ContactsContract.CommonDataKinds.Phone.TYPE + " = " +
ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE,
new String[]{contactID},
null);
if (cursorPhone.moveToFirst()) {
contactNumber = cursorPhone.getString(cursorPhone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
cursorPhone.close();
Log.d(TAG, "Contact Phone Number: " + contactNumber);
}
private void retrieveContactName() {
String contactName = null;
// querying contact data store
Cursor cursor = getContentResolver().query(uriContact, null, null, null, null);
if (cursor.moveToFirst()) {
// DISPLAY_NAME = The display name for the contact.
// HAS_PHONE_NUMBER =   An indicator of whether this contact has at least one phone number.
contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
}
cursor.close();
Log.d(TAG, "Contact Name: " + contactName);
}
}

main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<Button android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Select a Contact"
android:onClick="onClickSelectContact" />
<ImageView android:id="@+id/img_contact"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:adjustViewBounds="true"
android:contentDescription="Contacts Image"
/>

并将其添加到menifest文件：

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