【问题描述】：

我有一个viewpager/滑动标签。我希望能够从手机上已经存在的通讯录中获取 4 个联系人并将它们保存在应用程序中以供以后使用。我有代码来做一个活动的联系人选择器，但我的联系人页面是一个片段，我还没有让它工作。

任何想法或建议将不胜感激！

它连接到的主要活动的代码：

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.app.FragmentTransaction;
import android.support.v4.view.ViewPager;
import android.support.v7.app.ActionBar;
import android.support.v7.app.ActionBarActivity;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;



public class MainActivity2Activity extends ActionBarActivity implements ActionBar.TabListener, ViewPager.OnPageChangeListener 

private ViewPager mViewPager;


@Override
protected void onCreate(Bundle savedInstanceState) 
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main_activity2);


    PagerAdapter adapter = new PagerAdapter(getSupportFragmentManager());
    mViewPager = (ViewPager) findViewById(R.id.pager);
    mViewPager.setAdapter(adapter);

    mViewPager.setOnPageChangeListener(this);

    ActionBar actionBar = getSupportActionBar();
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

    ActionBar.Tab tab = actionBar.newTab().setText("Contacts").setTabListener(this);
    actionBar.addTab(tab);

    tab = actionBar.newTab().setText("GPS").setTabListener(this);
    actionBar.addTab(tab);

    tab = actionBar.newTab().setText("Message").setTabListener(this);
    actionBar.addTab(tab);




public class PagerAdapter extends FragmentPagerAdapter 

    public PagerAdapter(FragmentManager fm) 
        super(fm);
    

    public Fragment getItem(int arg0) 
        switch (arg0) 
            case 0:
                return new MainMenu_Contacts();
            case 1:
                return new MainMenu_GPS();
            case 2:
                return new MainMenu_Message();
            default:
                return null;
        
    
    public int getCount() 
        return 3;
    


//implements on pager selected
@Override
public void onPageScrolled(int i, float v, int i2) 



@Override
public void onPageSelected(int i) 
    getSupportActionBar().setSelectedNavigationItem(i);


@Override
public void onPageScrollStateChanged(int i) 




//implements tab listener
@Override
public void onTabSelected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) 
    mViewPager.setCurrentItem(tab.getPosition());


@Override
public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) 



@Override
public void onTabReselected(ActionBar.Tab tab, FragmentTransaction fragmentTransaction) 

主要活动的 XML：

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.view.ViewPager
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/pager"
android:layout_
android:layout_ />

联系人片段代码：

import android.app.Activity;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.support.v4.app.Fragment;

import android.view.View;

import android.widget.Button;

import android.view.View.OnClickListener;



public class MainMenu_Contacts extends Fragment implements OnClickListener 

private Button mBtnContacts;
private final int PICK = 1;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) 
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main_menu__contacts);
    mBtnContacts = (Button) findViewById(R.id.xBtnContacts);
    mBtnContacts.setOnClickListener(this);


@Override
public void onClick(View v) 
    // TODO Auto-generated method stub
    // Opening Contacts Window as a Window
    Intent intent = new Intent(Intent.ACTION_PICK,
            ContactsContract.Contacts.CONTENT_URI);
    // calling OnActivityResult with intenet And Some conatct for Identifie
    startActivityForResult(intent, PICK);


@Override
public void onActivityResult(int reqCode, int resultCode, Intent data) 
    super.onActivityResult(reqCode, resultCode, data);
    switch (reqCode) 
        case (PICK):
            if (resultCode == Activity.RESULT_OK) 
                Uri contactData = data.getData();
                Cursor c = managedQuery(contactData, null, null, null,     null);
                if (c.moveToFirst()) 
                    String name = c.getString(c
                            .getColumnIndexOrThrow(Contacts.People.NAME));
                    // TODO Whatever you want to do with the selected     contact
                    // name.
                
            
            break;
    

联系人的 XML：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_
android:layout_>
<Button android:layout_
    android:layout_ android:id="@+id/xBtnContacts"
    android:text="Pick Contacts" />
</LinearLayout>

【问题讨论】：

如果您需要进一步的帮助，请提供联系方式的代码

【参考方案1】：

通过ContentProvider 读取手机中的联系人，该ContentProvider 需要您的应用程序中的权限。也许这是你的问题，因为你没有提到它们。

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

【参考方案2】：

我通过以下步骤使用了联系人选择器。你可以用你的视图类改变ImageButton

ImageButton pick_contact = (ImageButton) findViewById(R.id.pick_contact);
pick_contact.setOnClickListener(new View.OnClickListener() 
    @Override
    public void onClick(View view) 
        Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.CommonDataKinds.Phone.CONTENT_URI);
        startActivityForResult(intent, PICK_CONTACT);
    
);

活动后期：

@Override
protected void onActivityResult(final int requestCode, int resultCode, Intent data) 

    if (data != null) 
        Uri result = data.getData();

        Cursor c = getContentResolver().query(
                ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                ContactsContract.CommonDataKinds.Phone._ID + "=?",
                new String[]result.getLastPathSegment(), null);

        if (c.getCount() >= 1 && c.moveToFirst()) 

            final String number = c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
            final String name = c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
        
    

重要提示：在AndroidManifest.xml中，添加

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