Question

我正在尝试使“弹出对话框注释”部分。在此“评论”部分中，我几乎做了所有事情，但面临新问题。

在这里，我使用“显示”对话框并添加新评论，但是当用户单击“输入评论”（Edittext）时。它隐藏在键盘下。因此，用户发布新评论会很麻烦。

这里是我的Xml文件：

Popup.xml：

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

    <android.support.v7.widget.RecyclerView
        android:id="@+id/popup_rcv"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="horizontal"
            android:layout_gravity="bottom">
            <EditText
                android:id="@+id/new_comment_et"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_weight="1"
                android:hint="Please enter Comment" />

            <Button
                android:id="@+id/comment_btn"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Submit" />
        </LinearLayout>
    </LinearLayout>
</LinearLayout>

先谢谢您

尝试一下

<?xml version="1.0" encoding="utf-8"?>

        android:layout_height="0dp"
        android:layout_weight="1" />

    <LinearLayout
        android:layout_width="match_parent"
