首先在清单文件和java文件中添加读取通讯录的权限
<!--允许应用程序写出到联系人--> <uses-permission android:name="android.permission.WRITE_CONTACTS"/> <!--允许应用程序读取到联系人--> <uses-permission android:name="android.permission.READ_CONTACTS"/>
运行时权限
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_CONTACTS) != PackageManager.PERMISSION_GRANTED || ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) { ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_CONTACTS, Manifest.permission.READ_CONTACTS}, 1); } }
之后activity_contact_resover.xml布局文件
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".ContactResoverActivity" android:orientation="vertical" > <TextView android:id="@+id/et_contact" android:layout_width="match_parent" android:layout_height="wrap_content"/> <EditText android:id="@+id/et_username" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="用户名" /> <EditText android:id="@+id/et_phone" android:layout_width="match_parent" android:layout_height="wrap_content" android:hint="电话" /> <Button android:id="@+id/btn_search" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="搜索" /> <Button android:id="@+id/btn_insert" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="插入" /> <Button android:id="@+id/btn_delete" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="删除" /> <Button android:id="@+id/btn_update" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="更新" /> <Button android:id="@+id/btn_search_all" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="查询所有" /> </LinearLayout>
接下里ContactResoverActivity文件，主要注释都已经给出了。
public class ContactResoverActivity extends AppCompatActivity implements View.OnClickListener { private TextView et_contact; //显示查询的信息 private EditText et_username; //用户名 private EditText et_phone; //电话 private Button btn_search; //搜索 private Button btn_insert;//插入 private Button btn_delete; //删除 private Button btn_update; //更新 private Button btn_search_all; //查询所有 private String selections; //查询条件 private String[] selection_args; //查询参数 //要查询的字段 String[] query_all = new String[]{ ContactsContract.CommonDataKinds.Identity.RAW_CONTACT_ID, //用户id ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, //联系人姓名 ContactsContract.CommonDataKinds.Phone.NUMBER //联系人电话 }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_contact_resover); et_contact = findViewById(R.id.et_contact); et_username = findViewById(R.id.et_username); et_phone = findViewById(R.id.et_phone); btn_search = findViewById(R.id.btn_search); btn_insert = findViewById(R.id.btn_insert); btn_delete = findViewById(R.id.btn_delete); btn_update = findViewById(R.id.btn_update); btn_search_all = findViewById(R.id.btn_search_all); btn_search_all.setOnClickListener(this); btn_insert.setOnClickListener(this); btn_delete.setOnClickListener(this); btn_search.setOnClickListener(this); btn_update.setOnClickListener(this); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_CONTACTS) != PackageManager.PERMISSION_GRANTED || ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) { ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_CONTACTS, Manifest.permission.READ_CONTACTS}, 1); } } } @Override public void onClick(View v) { switch (v.getId()) { case R.id.btn_insert: String name = et_username.getText().toString(); String phone = et_phone.getText().toString(); ContentValues values = new ContentValues(); Uri uri = getContentResolver().insert(ContactsContract.RawContacts.CONTENT_URI, values); long rawContentID = ContentUris.parseId(uri); if (!name.equals("")) { values.clear(); values.put(ContactsContract.Data.RAW_CONTACT_ID, rawContentID); values.put(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE); values.put(ContactsContract.CommonDataKinds.StructuredName.GIVEN_NAME, name); getContentResolver().insert(ContactsContract.Data.CONTENT_URI, values); } if (!phone.equals("")) { values.clear(); values.put(ContactsContract.Data.RAW_CONTACT_ID, rawContentID); values.put(ContactsContract.Data.MIMETYPE, ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE); values.put(ContactsContract.CommonDataKinds.Phone.TYPE, ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE); values.put(ContactsContract.CommonDataKinds.Phone.NUMBER, phone); getContentResolver().insert(ContactsContract.Data.CONTENT_URI, values); } Toast.makeText(this, "插入成功", Toast.LENGTH_SHORT).show(); break; case R.id.btn_search_all: //参数二：表示要查询的字段，如果为null，表示查询所有的字段 Cursor cursor1 = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, query_all, null, null, null); printQueryResult(cursor1); break; case R.id.btn_delete: String name1 = et_username.getText().toString(); if (!name1.equals("")) { getContentResolver().delete(ContactsContract.RawContacts.CONTENT_URI, ContactsContract.Contacts.DISPLAY_NAME + "=?", new String[]{name1}); Toast.makeText(this, "删除成功！", Toast.LENGTH_SHORT).show(); } break; case R.id.btn_search: String name_search = et_username.getText().toString(); Cursor cursor = getContentName(name_search); printQueryResult(cursor); break; case R.id.btn_update: String name_update = et_username.getText().toString(); String phone_update = et_phone.getText().toString(); Long rawContactId = 0L; ContentResolver resolver = getContentResolver(); ContentValues values1 = new ContentValues(); values1.put(ContactsContract.CommonDataKinds.Phone.NUMBER, phone_update); if (!name_update.equals("")) { Cursor cursor2 = getContentName(name_update); if (cursor2.moveToFirst()) { rawContactId = cursor2.getLong(0); } resolver.update(ContactsContract.Data.CONTENT_URI, values1, "mimetype=? and raw_contact_id=?" , new String[]{ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE, rawContactId + ""}); cursor2.close(); } break; } } private Cursor getContentName(String name_search) { selections = ContactsContract.Contacts.DISPLAY_NAME + "=?"; selection_args = new String[]{name_search}; Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, query_all, selections, selection_args, null); return cursor; } private void printQueryResult(Cursor cursor) { if (cursor != null) { et_contact.setText(""); while (cursor.moveToNext()) { String ID = cursor.getString(0); String stringName = cursor.getString(1); String phone = cursor.getString(2); et_contact.append("\n联系人ID:" + ID + "\n联系人姓名：" + stringName + "\n联系人电话:" + phone); } } cursor.close(); } }
效果如图所示：
