获取系统联系人三步，外加拨打电话：

1、添加权限：

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

2、开启系统联系人界面

    startActivityForResult(new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI), 0);

3、处理返回结果

 if (resultCode == Activity.RESULT_OK) {ContentResolver reContentResolverol = getContentResolver();Uri contactData = data.getData();@SuppressWarnings("deprecation")Cursor cursor = managedQuery(contactData, null, null, null, null);cursor.moveToFirst();name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));Cursor phone = reContentResolverol.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId,null,null);while (phone.moveToNext()) {num = phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));}et_name.setText(name);et_num.setText(num);
}

Ps：拨打电话：

Intent callIntent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + num));
startActivity(callIntent);

完整代码如下：（需要在清单文件中添加两个权限）
布局：

<LinearLayout 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"android:layout_margin="10dp"tools:context=".MainActivity"android:orientation="vertical"><EditTextandroid:id="@+id/et_name"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_margin="10dp"android:hint="plaease input your name..."/><EditTextandroid:id="@+id/et_phone"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_margin="10dp"android:hint="plaease input your phone num..."/><Buttonandroid:id="@+id/btn_getContacts"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_margin="10dp"android:hint="get num form system..."/><Buttonandroid:id="@+id/btn_call"android:layout_width="fill_parent"android:layout_height="wrap_content"android:layout_margin="10dp"android:hint="call the num..."/></LinearLayout>

代码：

package com.example.ricky.android_system_getcontacts;import android.app.Activity;
import android.content.ContentResolver;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;

}
