Question

我有自定义对话框片段，其中包含视图寻呼机，在视图中，寻呼机有一个编辑文本。当显示自定义对话框片段时，编辑文本具有焦点但软键盘未显示输入。

对话框的xml布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:htdu87="http://schemas.android.com/apk/res/com.htdu87.ekaraoke"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:background="@color/background_app" >

    <!-- <com.htdu87.ekaraoke.objects.LikeComment 
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/htdu87_like_comment"/> -->

    <com.htdu87.ekaraoke.classes.MyViewPager 
        android:layout_width="match_parent"
        android:layout_height="300dp"
        android:id="@+id/view_pager"
        htdu87:allow_sweep="true"/>

</LinearLayout>

Answer 1

也许这个答案，ListView而不是ViewPager可以帮到你？

Soft Keyboard Doesnt show when using adapter in DialogFragment

Answer 2

确保您没有使用android:inputType="none"的编辑文字并且没有在清单android:windowSoftInputMode="stateAlwaysHidden"

中使用它

软键盘未显示在自定义对话框片段中
