Ошибка AlertDialog для Android

Question

Я пытаюсь создать AlertDialog, но я получаю некоторые ошибки. Диалог отображается, когда пользователь нажимает ListView вещь.

Здесь AlertDialog функция:

private void showNewNotebookDialog() {
    LayoutInflater inflater = this.getLayoutInflater();
    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);
    dialogBuilder.setView(inflater.inflate(R.layout.notebook_new, null));
    dialogBuilder.setCancelable(true);
    dialogBuilder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {

        }
    });
    dialogBuilder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialog.cancel();
        }
    });
    AlertDialog dialog = dialogBuilder.create();
    dialog.show();
}

А вот и notebook_new.xml файл:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/notebook_new_parent"
    android:layout_width="fill_parent"
    android:layout_height="100dp">        
    <TextView android:text="New notebook"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="10dp"/>      
    <EditText android:id="@+id/notebook_new_edittext"
        android:hint="Enter a title"
        android:layout_width="match_parent"
        android:maxLines="1"/>        
</RelativeLayout>

И ошибки:

Answer 1

Вы скучаете по android:layout_height директива для вашего EditText составная часть. Вам нужно что-то вроде:

<EditText android:id="@+id/notebook_new_edittext"
    android:hint="Enter a title"
    android:layout_height="match_parent"
    android:layout_width="match_parent"
    android:maxLines="1"/>

Answer 2

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/notebook_new_parent"
    android:layout_width="fill_parent"
    android:layout_height="100dp">        
    <TextView android:text="New notebook"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="10dp"/>      
    <EditText android:id="@+id/notebook_new_edittext"
        android:hint="Enter a title"
        android:layout_width="match_parent"
        android:layout_height="match_parent" <!-- you are missing this line -->
        android:maxLines="1"/>        
</RelativeLayout>
