Android中擷取系統通訊錄連絡人並顯示在EditText

        好多時候，我們都要使用選擇連絡人的操作，自己寫的話 很麻煩，倒不如直接調用系統的通訊錄，這樣來的直接，來的方便

       下面我們來看需求：

 

需求：
一個EditText 點擊button的時候轉到系統通訊錄，選中其中一個通訊錄item返回當前介面且把
選中的連絡人號碼使用者名稱顯示在EditText 上。

 

 

直接上代碼：

import android.app.Activity;import android.content.ContentResolver;import android.content.Intent;import android.database.Cursor;import android.net.Uri;import android.os.Bundle;import android.provider.ContactsContract;import android.view.View;import android.widget.EditText;public class MainActivity extends Activity {    EditText text;    String username,usernumber;        @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        text = (EditText)findViewById(R.id.number);    }       public void click(View v){       startActivityForResult(new Intent(                Intent.ACTION_PICK,ContactsContract.Contacts.CONTENT_URI), 0);   }    @Override    protected void onActivityResult(int requestCode, int resultCode, Intent data) {        super.onActivityResult(requestCode, resultCode, data);        if (resultCode == Activity.RESULT_OK) {            ContentResolver reContentResolverol = getContentResolver();             Uri contactData = data.getData();             @SuppressWarnings("deprecation")            Cursor cursor = managedQuery(contactData, null, null, null, null);             cursor.moveToFirst();             username = 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()) {                 usernumber = phone.getString(phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));                 text.setText(usernumber+" ("+username+")");             }         }    }}
