android读取通讯录和使用系统通讯录
第一步：注册权限
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
第二步：接收的model类
public class ContactModel {
private String name;
private ArrayList<String > list;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public ArrayList<String> getList() {
return list;
}
public void setList(ArrayList<String> list) {
this.list = list;
}
}
第三步：mian——activity
public class MainActivity extends AppCompatActivity {
private Button button;
private ListView listView;
static final String TAG = "MainActivity";
ArrayList<ContactModel>dataList = new ArrayList<ContactModel>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
listView = (ListView)findViewById(R.id.contrcts_view);
readContacts();
MainAdapter adapter = new MainAdapter(this,dataList);
listView.setAdapter(adapter);
}
private void readContacts(){
Cursor cursor = null;
try {
cursor = this.getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
int contactIdIndex = 0;
int nameIndex = 0;
if(cursor.getCount() > 0) {
contactIdIndex = cursor.getColumnIndex(ContactsContract.Contacts._ID);
nameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
}
ContactModel model = null;
while(cursor.moveToNext()) {
model = new ContactModel();
String contactId = cursor.getString(contactIdIndex);
String name = cursor.getString(nameIndex);
// Log.i(TAG, contactId);
Log.i(TAG, "==============:" + name);
model.setName(name);
/*
* 查找该联系人的phone信息
*/
Cursor phones = this.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + contactId,
null, null);
int phoneIndex = 0;
if (phones.getCount() > 0) {
phoneIndex = phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
}
ArrayList <String>list = new ArrayList<String>();
while (phones.moveToNext()) {
String phoneNumber = phones.getString(phoneIndex);
Log.i(TAG, "==============:" + phoneNumber);
list.add(phoneNumber);
}
model.setList(list);
dataList.add(model);
}
}catch (Exception e){
Log.e(TAG,e.toString());
}finally {
if(cursor != null){
cursor.close();
}
}
}
}
第四步：adapter
public class MainAdapter extends BaseAdapter {
private Context context;
private List<ContactModel> list;
public MainAdapter(Context context, List<ContactModel>list){
this.context = context;
this.list = list;
}
@Override
public int getCount() {
return this.list.size();
}
@Override
public Object getItem(int i) {
return this.list.get(i);
}
@Override
public long getItemId(int i) {
return i;
}
@Override
public View getView(int i, View view, ViewGroup viewGroup) {
ViewHolder holder;
if(view == null){
view = LayoutInflater.from(this.context).inflate(R.layout.item_main,null);
holder = new ViewHolder();
holder.nameTV = (TextView)view.findViewById(R.id.name);
holder.phoneTV = (TextView)view.findViewById(R.id.phone);
view.setTag(holder);
}else{
holder = (ViewHolder)view.getTag();
}
ContactModel model = this.list.get(i);
holder.nameTV.setText(model.getName());
StringBuffer buffer = new StringBuffer();
for (int j=0;j<model.getList().size();j++){
if(j==0){
buffer.append(model.getList().get(j));
}else {
buffer.append("\n"+model.getList().get(j));
}
}
holder.phoneTV.setText(buffer.toString());
return view;
}
class ViewHolder{
TextView nameTV;
TextView phoneTV;
}
}
第五步：item 布局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="tom"
android:layout_margin="5dp"
android:id="@+id/name"/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="18580633453"
android:layout_margin="5dp"
android:id="@+id/phone"/>
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#d6d6d6"
/>
</LinearLayout>
main的布局就一个listview，如果不会的话我需要静静了
2.系统通讯录这里是使用fragement做的，要用startActivityForResult
textView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI); startActivityForResult(intent, 1); } }); @Override public void onActivityResult(int requestCode, int resultCode, Intent data) { super.onActivityResult(requestCode, resultCode, data); if (resultCode == Activity.RESULT_OK) { // ContentProvider展示数据类似一个单个数据库表 // ContentResolver实例带的方法可实现找到指定的ContentProvider并获取到ContentProvider的数据 ContentResolver reContentResolverol = getActivity(). getContentResolver(); // URI,每个ContentProvider定义一个唯一的公开的URI,用于指定到它的数据集 Uri contactData = data.getData(); // 查询就是输入URI等参数,其中URI是必须的,其他是可选的,如果系统能找到URI对应的ContentProvider将返回一个Cursor对象. Cursor cursor = getActivity().managedQuery(contactData, null, null, null, null); cursor.moveToFirst(); // 获得DATA表中的名字 username = cursor.getString(cursor .getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); // 条件为联系人ID String contactId = cursor.getString(cursor .getColumnIndex(ContactsContract.Contacts._ID)); // 获得DATA表中的电话号码，条件为联系人ID,因为手机号码可能会有多个 Cursor phone = reContentResolverol.query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId, null, null); while (phone.moveToNext()) { usernumber = phone .getString(phone .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); // et_mobile.setText(usernumber + " (" + username + ")"); toastShowShort(usernumber + " (" + username + ")"); } } }
