我写了一个简单的应用程序，显示联系人和图像。我正在获取联系人姓名和电话号码，但图像未进入imageview。所以任何人都请帮助我。 提前致谢。这是我的代码：
public class MainActivity extends Activity {
// Add a list to keep all the "name: number" strings
private List<String> mNameNumber = new ArrayList<String>();
private static final String TAG = MainActivity.class.getName();
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Cursor c = getContentResolver().query(
ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
String contactName, contactTelNumber = "";
String contactID;
String image_uri = "";
Bitmap bitmap = null;
// You only need to find these indices once
int idIndex = c.getColumnIndex(ContactsContract.Contacts._ID);
int hasNumberIndex = c
.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER);
int nameIndex = c
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
// This is simpler than calling getCount() every iteration
while (c.moveToNext()) {
contactName = c.getString(nameIndex);
contactID = c.getString(idIndex);
image_uri = c.getString(photoIndex);
Log.d(TAG, "Image" + image_uri + "contactName" + contactName);
ImageView profile = (ImageView) findViewById(R.id.imageView1);
try {
Bitmap mybtmp = BitmapFactory.decodeStream((InputStream)new URL(image_uri).getContent());
profile.setImageBitmap(mybtmp);
Log.d(TAG, "bitmap"+mybtmp);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
//setImageBitmap(my_btmp);
// If this is an integer ask for an integer
if (c.getInt(hasNumberIndex) > 0) {
Cursor pCur = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?", new String[] { contactID }, null);
while (pCur.moveToNext()) {
contactTelNumber = pCur
.getString(pCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
// Store the "name: number" string in our list
mNameNumber.add(contactName + ": " + contactTelNumber);
}
}
}
// Find the ListView, create the adapter, and bind them
ListView listView = (ListView) findViewById(R.id.listView1);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, mNameNumber);
listView.setAdapter(adapter);
}
}

实现自定义列表视图的更好方法是使用自定义适配器。以下网址为初学者提供了很好的示例 URL
答案 1 :(得分：0)
这是我的代码，用于显示与我的设备上的图像联系。 第1步：获取照片：
String urlThumbnail = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI));
您可以使用“人物”项目上的格式字符串保存此网址。 第2步：在ImageView上显示图像。
if (!itemContact.getUrlThumbnail().equals("")) {
final String thumbnailUrl = itemContact.getUrlThumbnail();
if (thumbnailUrl != null) {
final Bitmap thumbnail = fetchThumbnail(thumbnailUrl);
if (thumbnail != null) {
holder.avataContact.setImageBitmap(thumbnail);
}
}
} else {
holder.avataContact.setImageDrawable(getContext().getResources().getDrawable(R.drawable.ic_contact_picture));
}
// --------这是代码显示图片。
private Bitmap fetchThumbnail(String image_uri) {
Bitmap bitmap = null;
if (image_uri != null) {
System.out.println(Uri.parse(image_uri));
try {
bitmap = MediaStore.Images.Media.getBitmap(mContext.getContentResolver(), Uri.parse(image_uri));
System.out.println(bitmap);
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
return bitmap;
}
