android – 访问联系人并获取电子邮件地址

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);
    }

    }

解决方法

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,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,Email.CONTACT_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是按钮的onclick使用任何你想要的代码.
