如何调用Android联系人列表? [英] How to call Android contacts list?

问题描述

我正在制作一个 Android 应用，需要调用手机的联系人列表.我需要调用联系人列表功能，选择一个联系人，然后使用该联系人的姓名返回我的应用程序.这是我在互联网上得到的代码，但它不起作用.

I'm making an Android app, and need to call the phone's contact list. I need to call the contacts list function, pick a contact, then return to my app with the contact's name. Here's the code I got on the internet, but it doesnt work.

import android.app.ListActivity;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.Contacts.People;
import android.view.View;
import android.widget.ListAdapter;
import android.widget.ListView;
import android.widget.SimpleCursorAdapter;
import android.widget.TextView;

public class Contacts extends ListActivity {

    private ListAdapter mAdapter;
    public TextView pbContact;
    public static String PBCONTACT;
    public static final int ACTIVITY_EDIT=1;
    private static final int ACTIVITY_CREATE=0;

    // Called when the activity is first created. 
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        Cursor C = getContentResolver().query(People.CONTENT_URI, null, null, null, null);
        startManagingCursor(C);

        String[] columns = new String[] {People.NAME};
        int[] names = new int[] {R.id.row_entry};

        mAdapter = new SimpleCursorAdapter(this, R.layout.mycontacts, C, columns, names);
        setListAdapter(mAdapter);
    } // end onCreate()
    // Called when contact is pressed
    @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);

        Cursor C = (Cursor) mAdapter.getItem(position);
        PBCONTACT = C.getString(C.getColumnIndex(People.NAME));

        // RHS 05/06
        //pbContact = (TextView) findViewById(R.id.myContact);
        //pbContact.setText(new StringBuilder().append("b"));

        Intent i = new Intent(this, NoteEdit.class);
        startActivityForResult(i, ACTIVITY_CREATE);
    }
}

推荐答案

我不是 100% 确定您的示例代码应该做什么，但以下代码段应该可以帮助您调用联系人列表功能，选择联系人"，然后使用联系人姓名返回 [您的] 应用.

I'm not 100% sure what your sample code is supposed to do, but the following snippet should help you 'call the contacts list function, pick a contact, then return to [your] app with the contact's name'.

此过程分为三个步骤.

向您的应用程序清单添加读取联系人数据的权限.

Add a permission to read contacts data to your application manifest.

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

2.调用联系人选择器

在您的 Activity 中，创建一个 Intent，要求系统查找可以从 Contacts URI 中的项目执行 PICK 操作的 Activity.

2. Calling the Contact Picker

Within your Activity, create an Intent that asks the system to find an Activity that can perform a PICK action from the items in the Contacts URI.

Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);

调用startActivityForResult，传入这个Intent(在这个例子中是一个请求代码整数，PICK_CONTACT).这将导致 Android 在 People.CONTENT_URI 上启动一个注册为支持 ACTION_PICK 的 Activity，然后在做出(或取消)选择时返回此 Activity.>

Call startActivityForResult, passing in this Intent (and a request code integer, PICK_CONTACT in this example). This will cause Android to launch an Activity that's registered to support ACTION_PICK on the People.CONTENT_URI, then return to this Activity when the selection is made (or canceled).

startActivityForResult(intent, PICK_CONTACT);

3.聆听结果

同样在您的活动中，覆盖 onActivityResult 方法以侦听您在第 2 步中启动的选择联系人"活动的返回.您应该检查返回的请求代码是否与您的值匹配'期待，结果代码是 RESULT_OK.

3. Listening for the Result

Also in your Activity, override the onActivityResult method to listen for the return from the 'select a contact' Activity you launched in step 2. You should check that the returned request code matches the value you're expecting, and that the result code is RESULT_OK.

您可以通过对 data Intent 参数调用 getData() 来获取所选联系人的 URI.要获取所选联系人的姓名，您需要使用该 URI 创建新查询并从返回的游标中提取姓名.

You can get the URI of the selected contact by calling getData() on the data Intent parameter. To get the name of the selected contact you need to use that URI to create a new query and extract the name from the returned cursor.

@Override
public void onActivityResult(int reqCode, int resultCode, Intent data) {
  super.onActivityResult(reqCode, resultCode, data);

  switch (reqCode) {
    case (PICK_CONTACT) :
      if (resultCode == Activity.RESULT_OK) {
        Uri contactData = data.getData();
        Cursor c =  getContentResolver().query(contactData, null, null, null, null);
        if (c.moveToFirst()) {
          String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
          // TODO Whatever you want to do with the selected contact name.
        }
      }
      break;
  }
}
