得到一个图片从联系 [英] Getting a Photo from a Contact

问题描述

好吧，我只是想了解如何使用联系人的信息，但我有点卡住了。我想是能够显示联系人的图片。使用下面的code，我有，我将如何能够把照片在contact_entry接触的ImageView的？

 的ListView contacts_list =（ListView控件）findViewById（R.id.contacts_list）;

//获取数据库的URI
开放的我们的uri = ContactsContract.Contacts.CONTENT_URI;
//什么，从数据库抓取
的String []投影=新的String [] {
        ContactsContract.Contacts._ID，
        ContactsContract.Contacts.DISPLAY_NAME，
        ContactsContract.Contacts.PHOTO_ID
};

字符串排序顺序= ContactsContract.Contacts.DISPLAY_NAME +分页中局部ASC;

光标光标= managedQuery（URI，投影，NULL，NULL，排序顺序）;

的String []字段=新的String [] {
        ContactsContract.Data.DISPLAY_NAME
};

INT []值= {
        R.id.contactEntryText
};

SimpleCursorAdapter适配器=新SimpleCursorAdapter（这一点，R.layout.contact_entry，光标，
        字段值）;
contacts_list.setAdapter（适配器）;
 

contact_entry.xml

 ＆LT; XML版本=1.0编码=UTF-8＆GT？;

解决方案

也许这将帮助你（接触是通过的getId标识（））：

  / **
 返回：照片URI
 * /
公共乌里getPhotoUri（）{
    尝试 {
        光标CUR = this.ctx.getContentResolver（）查询（
                ContactsContract.Data.CONTENT_URI，
                空值，
                ContactsContract.Data.CONTACT_ID +=+ this.getId（）+和
                        + ContactsContract.Data.MIMETYPE +=
                        + ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE +'，空，
                空值）;
        如果（CUR！= NULL）{
            如果（！cur.moveToFirst（））{
                返回null; //没有照片
            }
        } 其他 {
            返回null; //在光标过程中的错误
        }
    }赶上（例外五）{
        e.printStackTrace（）;
        返回null;
    }
    乌里人= ContentUris.withAppendedId（ContactsContract.Contacts.CONTENT_URI，龙
            .parseLong（的getId（）））;
    返回Uri.withAppendedPath（人，ContactsContract.Contacts.Photo.CONTENT_DIRECTORY）;
}
 

用法是：

 开放的U = objItem.getPhotoUri（）;
如果（U！= NULL）{
        mPhotoView.setImageURI（U）;
} 其他 {
        mPhotoView.setImageResource（R.drawable.ic_contact_picture_2）;
}
 

Alright, I'm just trying to learn about using Contact information, but I'm a bit stuck. I would like to be able to display a picture for the contact. Using the following code that I have, how would I be able to put the photo for the contact in the ImageView in contact_entry?

ListView contacts_list = (ListView) findViewById(R.id.contacts_list);

// Gets the URI of the db
Uri uri = ContactsContract.Contacts.CONTENT_URI;
// What to grab from the db
String[] projection = new String[] {
        ContactsContract.Contacts._ID,
        ContactsContract.Contacts.DISPLAY_NAME,
        ContactsContract.Contacts.PHOTO_ID
};

String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";

Cursor cursor = managedQuery(uri, projection, null, null, sortOrder);

String[] fields = new String[] {
        ContactsContract.Data.DISPLAY_NAME
};

int[] values = { 
        R.id.contactEntryText
};

SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, R.layout.contact_entry, cursor,
        fields, values);
contacts_list.setAdapter(adapter);

contact_entry.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="54px">
    <ImageView
        android:id="@+id/contactPhoto"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" 
        android:src="@drawable/ic_contact_picture_3"/>
    <TextView 
        android:text="@+id/contactEntryText"
        android:id="@+id/contactEntryText"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"/>
</LinearLayout>

解决方案

Probably this will help you(contact is identified by getId()):

/**
 * @return the photo URI
 */
public Uri getPhotoUri() {
    try {
        Cursor cur = this.ctx.getContentResolver().query(
                ContactsContract.Data.CONTENT_URI,
                null,
                ContactsContract.Data.CONTACT_ID + "=" + this.getId() + " AND "
                        + ContactsContract.Data.MIMETYPE + "='"
                        + ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE + "'", null,
                null);
        if (cur != null) {
            if (!cur.moveToFirst()) {
                return null; // no photo
            }
        } else {
            return null; // error in cursor process
        }
    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }
    Uri person = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, Long
            .parseLong(getId()));
    return Uri.withAppendedPath(person, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
}

Usage is:

Uri u = objItem.getPhotoUri();
if (u != null) {
        mPhotoView.setImageURI(u);
} else {
        mPhotoView.setImageResource(R.drawable.ic_contact_picture_2);
}
