android如何取得本地通訊錄的頭像的原圖

標籤：通訊錄   頭像清晰圖   

上幾篇講contact的時候，取得的頭像都是存在資料庫中，通過:

 cursor = context.getContentResolver().query(                      ContentUris.withAppendedId(ContactsContract.Data.CONTENT_URI, photoId),                      new String[] { Photo.PHOTO }, null, null, null);  

來擷取

其實如果我們在本地通訊錄中，如果替一個連絡人加庫或拍照的圖片，那麼系統會把這個圖片的清晰圖儲存起來,如果要取到這個圖片，需要contactId

getListView().setOnItemClickListener(new OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> parent, View view, int position, long id) {try {Cursor cursor = (Cursor) getListAdapter().getItem(position);if (cursor == null) {return;}int contactId = cursor.getInt(Personal.ID_COLUMN_INDEX);Intent intent = new Intent();intent.setClass(ContactsList.this, ContactDetail.class);intent.putExtra("contactId",contactId);startActivity(intent);}catch(Exception ex) {ex.printStackTrace();}}});

如果我們想圖片帶圓角，可以這樣來實現:

     <LinearLayout        android:layout_width="fill_parent"        android:layout_height="fill_parent"        android:gravity="center" >                <FrameLayout            android:id="@+id/contacts_logo_layout"            android:layout_width="@dimen/incall_photo_view_size"            android:layout_height="@dimen/incall_photo_view_size" >            <ImageView                android:id="@+id/contact_photo"                android:layout_width="@dimen/incall_photo_view_size"                android:layout_height="@dimen/incall_photo_view_size"                />            <ImageView                android:id="@+id/contacts_logoborder"                android:layout_width="@dimen/incall_photo_view_size"                android:layout_height="@dimen/incall_photo_view_size"                android:background="@drawable/images_box" >            </ImageView>        </FrameLayout>            </LinearLayout>

java代碼:

@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);requestWindowFeature(Window.FEATURE_NO_TITLE);setContentView(R.layout.contact_detail);int contactId = getIntent().getIntExtra("contactId", 0);    contact_photo = (ImageView)findViewById(R.id.contact_photo);loadTask task = new loadTask(contactId);task.execute();}private class loadTask extends AsyncTask<Void, Void, Bitmap>{public loadTask(int id) {contactId = id;}private int contactId;@Overrideprotected Bitmap doInBackground(Void... params) {InputStream inputStream = openDisplayPhoto(contactId);BitmapFactory.Options opt = new BitmapFactory.Options();opt.inSampleSize = 1;Bitmap bitmap = BitmapFactory.decodeStream(inputStream, null, opt);return bitmap;}@Overrideprotected void onPostExecute(Bitmap result) {if(result != null) {contact_photo.setImageBitmap(result);}super.onPostExecute(result);}}public InputStream openDisplayPhoto(long contactId) {  <strong>//這個是取到清晰圖的inputStream的代碼</strong>     Uri contactUri = ContentUris.withAppendedId(Contacts.CONTENT_URI, contactId);     Uri displayPhotoUri = Uri.withAppendedPath(contactUri, Contacts.Photo.DISPLAY_PHOTO);     try {         AssetFileDescriptor fd =        this.getContentResolver().openAssetFileDescriptor(displayPhotoUri, "r");         return fd.createInputStream();     } catch (IOException e) {     e.printStackTrace();         return null;     } }
