Android：当软输入键盘出现时，Recyclerview不会调整大小 [英] Android: Recyclerview not resizing when softinput keyboard appears

问题描述

我有一个包含片段的活动，片段包含自定义视图。 customview包含一个edittext，并在其下方是一个高度为match_parent的recyclerview。当用户专注于edittext时，会出现一个软输入键盘。不幸的是，这个键盘隐藏了它下面的一半回收视图。我希望recyclerview调整大小到屏幕的剩余可见高度（在edittext下），这样列表中的项目不会被键盘隐藏。

I have an activity that contains a fragment and the fragment contains a customview. The customview contains an edittext and directly below it a recyclerview with height of match_parent. When the user gets focus on the edittext a softinput keyboard appears.. unfortunately this keyboard hides half the recyclerview underneath it. I want the recyclerview to resize to the remaining visible height of the screen (under the edittext) so that items in the list aren't hidden by the keyboard.

我已尝试为清单中的活动设置adjustresize，但它没有效果：

I've tried setting adjustresize for the activity in the manifest but it has no effect:

android:windowSoftInputMode="adjustResize"

我试过设置我的应用基本主题的主题（如果我的自定义主题中的某些内容导致问题） - 没有效果：

I've tried setting my app theme to a base theme (in case something in my custom theme was causing a problem) - no effect:

android:theme="@style/Theme.AppCompat.NoActionBar"

我已经检查过以确保没有framelayouts在层次结构的任何地方到必须调整大小的视图（我读了一个SO线程，这可能是一个问题） - 没有。

I've checked to make sure there are no framelayouts anywhere down the hierarchy to the view that has to be resized (I read an SO thread that it could be a problem) - there are none.

我已经检查了活动，片段，自定义视图和连接的每个适配器，以确保我没有在任何地方调用getWindow（我不是）。

I've checked the activity, the fragment, the customview and every adapter connected to make sure that I'm not calling getWindow anywhere (I'm not).

自定义视图在运行时膨胀从viewstub。这有连接吗？

The customview is inflated at runtime from a viewstub. Could this have a connection?

编辑：

父母的内容：

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/parent_root"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >
...


    <ViewStub
        android:id="@+id/viewstub_outername"
        android:layout="@layout/viewstub_thatIneed"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />

</RelativeLayout>

viewstub的内容：

contents of the viewstub:

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/viewstub_root"
    android:layout_height="match_parent"
    android:layout_width="match_parent"
    android:background="@android:color/white"
    >

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerview1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginTop="20dp"
        android:visibility="invisible"
        />

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerview2"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginTop="20dp"
        android:visibility="invisible"
        />

</RelativeLayout>

如此显示键盘：

public static void showSoftKeyboard(Activity activity) {
    View view = activity.getCurrentFocus();
    InputMethodManager inputManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
    inputManager.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT);
}

推荐答案

不要做任何事清单文件。只需使用

Don't do anything in manifest file. Just use

((LinearLayoutManager)recyclerView.getLayoutManager()).setStackFromEnd(true);

这样可以处理Recyclerview的大小调整。

This will take care of recyclerview resizing.
