Android TextInputLayout编辑文本计数器在LinearLayout中脱离屏幕运行

Android TextInputLayout编辑文本计数器在LinearLayout中脱离屏幕运行,android,Android,我试图让我的EditText占据屏幕顶部工具栏和底部宽提交按钮之间剩余的空白 但是,当我使用match\u parent处理该EditText时,计数器会从屏幕上消失(最后出现在按钮后面)。我似乎不知道该如何表现出来 <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http:

我试图让我的

但是,当我使用
match\u parent

下面是我想要它的样子(右下角有
0/300
计数器):


请尝试以下针对您的布局更新的xml代码:

我希望它能对您有所帮助。

试着改用RelativeLayout,认为问题在于您的布局:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout     
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.myapp.app.PostActivity">

<android.support.design.widget.AppBarLayout
    android:id="@+id/appBarLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        android:overScrollMode="never"
        app:popupTheme="@style/AppTheme.PopupOverlay" />

</android.support.design.widget.AppBarLayout>


<LinearLayout
    android:id="@+id/textLinearLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@id/appBarLayout"
    android:layout_above="@id/submitArea"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    >

    <android.support.design.widget.TextInputLayout
        android:id="@+id/textContainer"
        android:layout_width="match_parent"
        android:layout_height="match_parent"

        android:scrollbars="vertical"
        app:counterEnabled="true"
        app:counterMaxLength="300">

        <EditText
            android:id="@+id/EditText"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="#00000000"
            android:gravity="top|left"
            android:inputType="textMultiLine|textCapSentences"
            android:maxLength="300"
            android:scrollbars="vertical"/>

    </android.support.design.widget.TextInputLayout>

</LinearLayout>


<LinearLayout
    android:id="@+id/submitArea"
    android:layout_width="match_parent"
    android:layout_height="60dp"
    android:layout_alignParentBottom="true"
    android:orientation="horizontal">

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

</RelativeLayout>

技巧是使用下面的
android:layout\u
和上面的
android:layout\u
作为中间布局,使用
android:layout\u alignParentBottom=“true”
作为提交按钮


希望这有帮助;)

你能上传你想要的截图或图片吗?@Kae10 Done。看到右下角的计数器了吗?那么
tvCounter
TextView我就必须用Java代码更新自己了?是的。我明白了,你需要根据你的要求改变。我希望不必这样做,计数器只会自动更新字符计数=)
