I want to fetch the photo of the contact while a user enters number.By using phone number i am getting users name but for image it shows null.
我的code为以下内容：
my code is following :
public class NewtempActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final ImageView img = (ImageView) findViewById(R.id.imageView1);
final EditText edit = (EditText) findViewById(R.id.editText1);
TextView txt = (TextView) findViewById(R.id.textView1);
Button btn = (Button) findViewById(R.id.button1);
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Log.d("Girish", "Clicked");
String name = getContactNameFromNumber(edit.getText()
.toString(), getApplicationContext());
img.setImageBitmap(BitmapFactory
.decodeFile(ContactsContract.PhoneLookup._ID));
Log.d("Girish",
""
+ (BitmapFactory
.decodeFile(ContactsContract.PhoneLookup._ID)));
Toast.makeText(getApplicationContext(), name, name.length())
.show();
}
});
}
public String getContactNameFromNumber(String number, Context ctx) {
/*
* // define the columns I want the query to return String[] projection
* = new String[] { ContactsContract.PhoneLookup.DISPLAY_NAME,
* ContactsContract.PhoneLookup.NUMBER, };
*/
// encode the phone number and build the filter URI
Uri contactUri = Uri.withAppendedPath(
ContactsContract.PhoneLookup.CONTENT_FILTER_URI,
Uri.encode(number));
// query time
// Cursor c = ctx.getContentResolver().query( contactUri, projection,
// null,
Cursor c = ctx.getContentResolver().query(contactUri, null, null, null,
null);
// if the query returns 1 or more results
// return the first result
if (c.moveToFirst()) {
String name = c.getString(c
.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
return name;
}
// return the original number if no match was found
return number;
}
public static Bitmap loadContactPhoto(ContentResolver cr, long id) {
Uri uri = ContentUris.withAppendedId(
ContactsContract.Contacts.CONTENT_URI, id);
InputStream input = ContactsContract.Contacts
.openContactPhotoInputStream(cr, uri);
// InputStream input = ContactsContract.Contacts.Photo
if (input == null) {
return null;
}
return BitmapFactory.decodeStream(input);
}
public InputStream openPhoto(long contactId) {
Uri contactUri = ContentUris.withAppendedId(Contacts.CONTENT_URI,
contactId);
Uri photoUri = Uri.withAppendedPath(contactUri,
Contacts.Photo.CONTENT_DIRECTORY);
Cursor cursor = getContentResolver().query(photoUri, null, null, null,
null);
if (cursor == null) {
return null;
}
try {
if (cursor.moveToFirst()) {
byte[] data = cursor.getBlob(0);
if (data != null) {
return new ByteArrayInputStream(data);
}
}
} finally {
cursor.close();
}
return null;
}
}
请建议我在哪里，我在做wrong.I增加了读取联系人权限也
please suggest me where i am doing wrong.I have added read contact permission also
推荐答案
由通过你的codeI才知道像你试图从数量联系人姓名。并使用所需的接触式图像..但你永远不叫你做的联系人PIC的功能.. :) ..所以你可以做的是采取 ID 从联系电话和拍照上 ID 。所以你会得到的照片数量。
by going through your code i came to know like You are trying to get the contact name from the number. and using that you want the contact image.. but you never called the functions which you made for the contact pic..:).. so what you can do is take id from the contact number and take photo on that id. so you will get the photo for the number..
