Android 由data 獲取聯系人信息。
//跳轉到聯系人界面
private void pickContact() {
// Create an intent to "pick" a contact, as defined by the content provider URI
Intent intent = new Intent(Intent.ACTION_PICK, Contacts.CONTENT_URI);
startActivityForResult(intent, PICK_CONTACT_REQUEST);
}
//返回來的Intent中的data數據是用戶選擇的聯系人的Uri ，表示資源的位置，以便ContentProvider去查找（query）資源(The URI, using the content:// scheme, for the content to retrieve)
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == Activity.RESULT_OK && requestCode == PICK_CONTACT_REQUEST) {
System.out.println("data.getData() " + data.getData());
// 輸出為： content://com.android.contacts/contacts/lookup/0r5-385C3A525C/5
Cursor cursor = getContentResolver().query(data.getData(), new String[] {Contacts.DISPLAY_NAME}, null, null, null);
if (cursor.moveToFirst()) {
int columnIndex = cursor.getColumnIndex(Contacts.DISPLAY_NAME);
String name = cursor.getString(columnIndex);
System.out.println(name);
}
}
}
