我有一个code snappet用于访问联系人。当用户点击该按钮，然后在联系人列表将是开放的，用户可以从通讯录中选择一个人，这个人的电子邮件地址应写在的EditText。我可以从人哪个用户选择接收电子邮件。但我不能将它设置为EditText上。

 静态字符串email =;

解决方案

现在用低于code从选定的联系人收到的电子邮件地址 -

 公共无效doLaunchContactPicker（查看视图）{
    意图contactPickerIntent =新的意图（Intent.ACTION_PICK，Contacts.CONTENT_URI）;
    startActivityForResult（contactPickerIntent，CONTACT_PICKER_RESULT）;
}

保护无效onActivityResult（INT申请code，INT结果code，意图数据）
{
    如果（结果code == RESULT_OK）{
        开关（要求code）
        {
        案例CONTACT_PICKER_RESULT：
            光标光标= NULL;
            字符串email =，NAME =;
            尝试 {
                开放的结果= data.getData（）;
                Log.v（DEBUG_TAG，有一个接触的结果：+ result.toString（））;

                //从URI获得接触式ID
                字符串ID = result.getLastPathSegment（）;

                //查询所有电子邮件
                光标= getContentResolver（）查询（Email.CONTENT_URI，空，Email.CONTACT_ID +=？，新的String [] {ID}，空）。

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

doLaunchContactPicker 是按钮使用code，无论你想要的一个onclick。

I have a code snappet for accessing to Contacts . When user click the button then the contacts list will be open and user can choose a person from contacts and the person's email adress should be write on a edittext. I can receive the email from the persons which user select. But I cant set it to the edittext.

static String email = "";


imgbtnaddfromcontacts.setOnClickListener(new OnClickListener() {
            @Override

Am using below code for getting email address from selected contact -

public void doLaunchContactPicker(View view) {

    startActivityForResult(contactPickerIntent, CONTACT_PICKER_RESULT);
}

@Override

{
    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);

                    Log.v(DEBUG_TAG, "Got email: " + email);
                } else {

                }
            } catch (Exception e) {

                EditText personEntry = (EditText) findViewById(R.id.person);
                emailEntry.setText(email);

                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 is an onclick of Button Use the code wherever you wants.
