推荐答案

不幸的是，这是Google上的一个错误，我已经提交了一个错误问题 https://code.google.com/p/android/issues/detail ?id = 231576

Sadly, this is a mistake on Google and I have filed a bug issue https://code.google.com/p/android/issues/detail?id=231576

与此同时解决此问题的方法是:

The hack to get around this in the mean time is to:

创建此布局

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="48dp"
    android:layout_marginBottom="48dp"
    android:overScrollMode="ifContentScrolls">

    <LinearLayout
        android:id="@+id/edittext_container"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="20dp"
        android:orientation="vertical">

        <EditText
            android:id="@android:id/edit"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:paddingStart="4dp"
            android:paddingEnd="4dp" />

    </LinearLayout>

</ScrollView>

然后在创建对象(EditTextPreference editTextPreference = new EditTextPreference(context))之后，调用setDialogLayoutResource(R.layout.THE_LAYOUT_ABOVE);

Then after you create your object (EditTextPreference editTextPreference = new EditTextPreference(context)), call setDialogLayoutResource(R.layout.THE_LAYOUT_ABOVE);

这将立即解决问题
