访问联系人并获取电子邮件地址

Question

我有一个用于访问联系人的代码段.当用户单击该按钮时,联系人列表将打开,用户可以从联系人中选择一个人,并且该人的电子邮件地址应该在edittext上写入.我可以收到用户选择的人的电子邮件.但我无法将其设置为edittext.

static String email = "";


imgbtnaddfromcontacts.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                if (v == imgbtnaddfromcontacts) {
                    try 
                    {
                        Intent intent = new Intent(Intent.ACTION_PICK,
                                ContactsContract.Contacts.CONTENT_URI);
                        startActivityForResult(intent, 1);

                    } catch (Exception e) {
                        e.printStackTrace();
                        Log.e("Error in intent : ", e.toString());
                    }

        });
        kimeTxt.setText(email);

使用以下代码从所选联系人处获取电子邮件地址 -

public void doLaunchContactPicker(View view) {
    Intent contactPickerIntent = new Intent(Intent.ACTION_PICK,Contacts.CONTENT_URI);
    startActivityForResult(contactPickerIntent, CONTACT_PICKER_RESULT);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) 
{
    if (resultCode == RESULT_OK) {
        switch (requestCode) 
        {
        case CONTACT_PICKER_RESULT:
            Cursor cursor = null;
            String email = "", name = "";
            try {
                Uri result = data.getData();
                Log.v(DEBUG_TAG, "Got a contact result: " + result.toString());

                // get the contact id from the Uri
                String id = result.getLastPathSegment();

                // query for everything email
                cursor = getContentResolver().query(Email.CONTENT_URI,  null, Email.CONTACT_ID + "=?", new String[] { id }, null);

                int nameId = cursor.getColumnIndex(Contacts.DISPLAY_NAME);

                int emailIdx = cursor.getColumnIndex(Email.DATA);

                // let's just get the first email
                if (cursor.moveToFirst()) {
                    email = cursor.getString(emailIdx);
                    name = cursor.getString(nameId);
                    Log.v(DEBUG_TAG, "Got email: " + email);
                } else {
                    Log.w(DEBUG_TAG, "No results");
                }
            } catch (Exception e) {
                Log.e(DEBUG_TAG, "Failed to get email data", e);
            } finally {
                if (cursor != null) {
                    cursor.close();
                }
                EditText emailEntry = (EditText) findViewById(R.id.editTextv);
                EditText personEntry = (EditText) findViewById(R.id.person);
                emailEntry.setText(email);
                personEntry.setText(name);
                if (email.length() == 0 && name.length() == 0) 
                {
                    Toast.makeText(this, "No Email for Selected Contact",Toast.LENGTH_LONG).show();
                }
            }
            break;
        }

    } else {
        Log.w(DEBUG_TAG, "Warning: activity result not ok");
    }
}

doLaunchContactPicker是一个Button在任何地方使用代码的onclick .

You can achieve it like this     \n\n   public class Abc extends Activity{\n        EditText kimeTxt;\n            Intent i;                                  \n              Bundle b ;    \n            @Override  \n\n            protected void onCreate(Bundle savedInstanceState) {\n                // TODO Auto-generated method stub\n                super.onCreate(savedInstanceState);\n                setContentView(R.layout.add_course);\n        kimeTxt= (EditText)findViewById(R.id.emailid);\n\n        }\n\n\n        @Override\n            public void onActivityResult(int reqCode, int resultCode, Intent data) {\n                super.onActivityResult(reqCode, resultCode, data);\n\n                try {\n                    if (resultCode == Activity.RESULT_OK) {\n                        // Get data\n                        Uri contactData = data.getData();\n                        // Cursor\n                        Cursor cur = managedQuery(contactData, null, null, null, null);\n                        ContentResolver contect_resolver = getContentResolver();\n\n                        // List\n                        if (cur.moveToFirst()) {\n                            String id = cur\n                                    .getString(cur\n                                            .getColumnIndexOrThrow(ContactsContract.Contacts._ID));\n\n                            Cursor phoneCur = contect_resolver.query(\n                                    ContactsContract.CommonDataKinds.Phone.CONTENT_URI,\n                                    null,\n                                    ContactsContract.CommonDataKinds.Phone.CONTACT_ID\n                                            + " = ?", new String[] { id }, null);\n\n                            Cursor emailCur = contect_resolver.query(\n                                    ContactsContract.CommonDataKinds.Email.CONTENT_URI,\n                                    null,\n                                    ContactsContract.CommonDataKinds.Email.CONTACT_ID\n                                            + " = ?", new String[] { id }, null);\n\n                            if (phoneCur.moveToFirst()) {\n                                name = phoneCur\n                                        .getString(phoneCur\n                                                .getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));\n                                no = phoneCur\n                                        .getString(phoneCur\n                                                .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));\n\n                            }\n\n                            while (emailCur.moveToNext()) {\n                                // This would allow you get several email addresses\n                                // if the email addresses were stored in an array\n                                email = emailCur\n                                        .getString(emailCur\n                                                .getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));\n\n                                if (email != null) \n                                {\n                                    seciliEmail = email;\n                                } else {\n                                    Toast.makeText(EpostaIletActivity.this,\n                                            "Ki\xc5\x9finin eposta hesab\xc4\xb1 bulunmamaktad\xc4\xb1r.",\n                                            Toast.LENGTH_SHORT);\n                                    Log.w("Error: ", "Ki\xc5\x9finin eposta hesab\xc4\xb1 yok.");\n                                }\n                            }\n\n                            Log.e("Phone no & name & email :***: ", name + " : " + no + ":" + email);\n                            // txt.append(name + " : " + no + "\\n");\n\n                            id = null;\n                            name = null;\n                            no = null;\n                            seciliEmail = "xxx";\n                            phoneCur = null;\n                            emailCur.close();\n                        }\n\n\n    // can set email id here \n\n\n\n      kimeTxt.setText(email);\n\n\n                        contect_resolver = null;\n                        cur = null;\n                        // populateContacts();\n\n                    }\n                } catch (IllegalArgumentException e) {\n                    e.printStackTrace();\n                    Log.e("IllegalArgumentException :: ", e.toString());\n                } catch (Exception e) {\n                    e.printStackTrace();\n                    Log.e("Error :: ", e.toString());\n                }\n        }\n
