java - 警报对话框的 inflated layout 不起作用

Question

我有以下方法，在允许用户访问“设置”菜单之前，我必须确认用户的密码。为此，我让他再次登录，因为 Parse(我的云存储)不允许我确认密码。到目前为止，一切都很好。问题是当我将 view 膨胀到我的 AlertDialog 以使用自定义 button 和 EditText 时。您可以在下面的代码中看到我对 Button 部分进行了注释，因为当我尝试获取 onClickListener 时它不起作用。它只是什么都不做。所以我目前正在使用 alertDialogPositiveButton 并且没问题。第二个问题也是真正的问题是我无法检索插入到 editText 中的数据。 SUpassword3 始终等于空白，而不是 null。有人可以帮忙吗？

方法:

public void confirmPassword(){

        final LayoutInflater inflateSetup = getLayoutInflater();

        AlertDialog.Builder alertSetup = new AlertDialog.Builder(this);
        alertSetup.setView(inflateSetup.inflate(R.layout.inflate_setup, null));
        alertSetup.setPositiveButton("Confirm", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                System.out.println("User has clicked the [confirm] button");
                View viewInflate_setup = inflateSetup.inflate(R.layout.inflate_setup, null);
                edtPassword3 = (EditText)viewInflate_setup.findViewById(R.id.edtPassword3);
                SUpassword3 = edtPassword3.getText().toString();

                final ParseUser beforeConfirmPassword = ParseUser.getCurrentUser();
                ParseUser.logInInBackground(beforeConfirmPassword.getUsername(), SUpassword3, new LogInCallback() {
                    @Override
                    public void done(ParseUser parseUser, ParseException e) {
                        if(e==null){
                            //password confirmed, logout last user and go to next setup
                            System.out.println("Password [" +SUpassword3+ "] and user [" +beforeConfirmPassword.getUsername()+ "] confirmed, logout last user and go to setup");
                            beforeConfirmPassword.logOut();
                        }else{
                            //passwords don't match
                            System.out.println("Password don't match: [" +SUpassword3 + "] USER [" +beforeConfirmPassword.getUsername()+ "]");
                        }
                    }
                });
            }
        });
        final AlertDialog dialogSetup = alertSetup.create();
        dialogSetup.show();


/**
        btnConfirmPassowod = (Button)viewInflate_setup.findViewById(R.id.btnConfirm);
        btnConfirmPassowod.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(final View v) {
                System.out.println("User has clicked the [confirm] button");
                final ParseUser beforeConfirmPassword = ParseUser.getCurrentUser();
                ParseUser.logInInBackground(beforeConfirmPassword.getUsername(), SUpassword3, new LogInCallback() {
                    @Override
                    public void done(ParseUser parseUser, ParseException e) {
                        if(e==null){
                            //password confirmed, logout last user and go to next setup
                            System.out.println("Password confirmed, logout last user and go to setup");
                            beforeConfirmPassword.logOut();
                        }else{
                            //passwords don't match
                            dialogSetup.dismiss();
                            Snackbar.make(v, "Wrong password, try again.", Snackbar.LENGTH_LONG)
                                    .setAction("Action", null).show();
                        }
                    }
                });
            }
        }); */
    }

inflate_setup.xml(我在alertDialog上膨胀的xml文件)

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="textPassword"
        android:ems="10"
        android:id="@+id/edtPassword3"
        android:layout_gravity="center_horizontal"
        android:hint="@string/EN_txt.confirmPassword"
        />
<Button
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="New Button"
    android:id="@+id/btnConfirm"
    android:layout_gravity="center_horizontal" />

</LinearLayout>

最终版本(工作):

public void confirmPassword(){

        final LayoutInflater inflateSetup = getLayoutInflater();
        final View viewInflate_setup = inflateSetup.inflate(R.layout.inflate_setup, null);

        AlertDialog.Builder alertSetup = new AlertDialog.Builder(this);
        alertSetup.setView(viewInflate_setup);
        alertSetup.setPositiveButton("Confirm", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                System.out.println("User has clicked the [confirm] button");

                edtPassword3 = (EditText)viewInflate_setup.findViewById(R.id.edtPassword3);
                SUpassword3 = edtPassword3.getText().toString();

Answer 1

您在 onClickListener 中膨胀了另一个 View 。这就是为什么您实际上检查另一个 edtPassword3 的文本，而不是用户可见的文本。应该是这样的:

View view = inflateSetup.inflate(R.layout.inflate_setup;
final EditText edtPassword3 = (EditText)viewInflate_setup.findViewById(R.id.edtPassword3);
alertSetup.setView(view, null));
  alertSetup.setPositiveButton("Confirm", new DialogInterface.OnClickListener() {
            @Override 
            public void onClick(DialogInterface dialog, int which) {
                System.out.println("User has clicked the [confirm] button");
                SUpassword3 = edtPassword3.getText().toString();
