Android 全屏文本输入文本不显示计数器

我正在努力使屏幕与整个屏幕相适应，但也不是没有问题：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    android:orientation="vertical"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="16dp"
    tools:context=".MainActivity">

    <com.google.android.material.textfield.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:counterEnabled="true"
        app:counterMaxLength="1000"
        app:passwordToggleEnabled="false"
        app:endIconMode="none">

        <com.google.android.material.textfield.TextInputEditText
            android:id="@+id/edit_text"
            android:hint="Type here..."
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:maxLength="1000"
            android:gravity="top"/>

    </com.google.android.material.textfield.TextInputLayout>

</LinearLayout>

<>结果是计数器消失，提示出现在中间。如果我更改为包装内容，它将恢复正常行为。例如：

---

因此，基本上我只需显示计数器即可，将提示与顶部对齐是次要的。

我做了测试，但在我的设备上无法正常工作：

<?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="match_parent"
    android:padding="16dp"
    xmlns:app="http://schemas.android.com/apk/res-auto">


    <com.google.android.material.textfield.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:counterEnabled="true"
        app:counterMaxLength="1000"
        app:passwordToggleEnabled="false"
        >

        <com.google.android.material.textfield.TextInputEditText
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:id="@+id/edit_text"
            android:hint="Type here..."
            android:maxLength="1000"
            android:gravity="top|left"/>

    </com.google.android.material.textfield.TextInputLayout>


</LinearLayout>

---

只需尝试重量，而不是匹配父母<代码>android:layout_weight=“1” 计数器将可见

点击EditText或EditText处于焦点时，提示对齐是正常的。由于EditText处于全屏状态，请求焦点将解决提示对齐问题

 TextInputEditText tv = findViewById( R.id.edit_text );
 tv.setInputType( InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_MULTI_LINE );
 tv.requestFocus();

您的布局如下所示`

<LinearLayout
    android:orientation="vertical"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="16dp"
    >

    <com.google.android.material.textfield.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:counterEnabled="true"
        app:counterMaxLength="1000"
        app:counterTextColor="@color/black"
        app:passwordToggleEnabled="false"
        app:endIconMode="none">

        <com.google.android.material.textfield.TextInputEditText
            android:id="@+id/edit_text"
            android:hint="Type here..."
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:maxLength="1000"
            android:gravity="top"/>

    </com.google.android.material.textfield.TextInputLayout>

</LinearLayout>`

`

我会切换到

EditText

，而不是

textinputtext

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
    android:orientation="vertical"
    android:padding="16dp"
    tools:context=".MainActivity">

    <com.google.android.material.textfield.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:counterEnabled="true"
        app:counterMaxLength="1000"
        app:endIconMode="none"
        app:passwordToggleEnabled="false">

        <EditText
            android:id="@+id/edit_text"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:ems="10"
            android:hint="Type here..."
            android:inputType="textPersonName"
            android:maxLength="1000" />

    </com.google.android.material.textfield.TextInputLayout>

</LinearLayout>

只需将android:layout_weight=“1”交给您的文本输入文本即可。这个把戏对我有用

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    android:orientation="vertical"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="16dp"
    >

    <com.google.android.material.textfield.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:counterEnabled="true"
        app:counterMaxLength="1000"
        app:counterOverflowTextAppearance="@dimen/_20sdp"
       >

        <com.google.android.material.textfield.TextInputEditText
            android:id="@+id/edit_text"
            android:hint="Type here..."
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:maxLength="1000"
            android:gravity="top"/>

    </com.google.android.material.textfield.TextInputLayout>

</LinearLayout>

希望这对你有帮助

布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    android:orientation="vertical"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="16dp">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    <com.google.android.material.textfield.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:passwordToggleEnabled="false"
        app:endIconMode="none">

        <com.google.android.material.textfield.TextInputEditText
            android:id="@+id/edit_text"
            android:hint="Type here..."
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:maxLength="1000"
            android:gravity="top"/>

    </com.google.android.material.textfield.TextInputLayout>
        <TextView
            android:id="@+id/txtcount"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentTop="true"
            android:layout_alignParentEnd="true"
            android:textColor="@color/colorAccent"
            android:textSize="10sp"
            android:visibility="gone"
            android:text="24"/>
    </RelativeLayout>
</LinearLayout>

计数器也在edittext中？@Umair尝试过，但sameI问了一个问题，但没有告诉你做什么；）你说的“柜台”是什么意思？你能分享你认为“正常行为”的截图吗？“StaCu没有显示我的设备上的计数器（OnPrand 6 Android 10），而不是仿真器（Android 7.1）<代码> Android：LayOutoSuth=“1”< /Cord> Work，但是你不需要设置<代码> Android：LayOutoHealth=“MatkHyPrime'”的

文本输入文本
