Android TextInputLayout 提示与 EditText 提示重叠

Android TextInputLayout hint overlaps EditText hint

我遇到了一个奇怪的问题,我有一个 InputTextLayout 和一个 EditText,我正在尝试实现类似的东西(如下图所示)(图片来自 material 设计指南:https://material.io/guidelines/components/text-fields.html#text-fields-layout),其中有两个单独的提示。我通过向两种布局添加 android:hint 来做到这一点。这很好用,但是当焦点从这里移开时,"label" 向下移动并与 "placeholder" 文本重叠。 (仅当用户未提供任何输入且编辑文本为空时 - 两个提示重叠)。关于如何解决这个问题的任何指示?

作为一项要求,我需要两个提示都存在,并且 "Label" 不应在焦点更改时下移。两个提示都应该保留在它们的位置

 <android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Label">

        <android.support.v7.widget.AppCompatEditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="Placeholder"
            android:inputType="textCapWords"
            />

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

    <android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Placeholder">

        <android.support.v7.widget.AppCompatEditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
           
            android:inputType="textCapWords"
            />

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

使用下面的代码。它应该可以正常工作。

<android.support.design.widget.TextInputLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="8dp"
            android:layout_marginTop="8dp"
            android:textColorHint="@color/white">

            <EditText

                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="Placeholder"
                android:inputType="text"
                android:textColor="@color/white"
                android:textColorHint="@color/white" />
        </android.support.design.widget.TextInputLayout>

AppcompatEditTextTextInputLayout

中删除提示

仅在 AppcompatEditTextTextInputLayout

中使用 android:hint=""
 <android.support.design.widget.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >

    <android.support.v7.widget.AppCompatEditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Placeholder"
        android:inputType="textCapWords"
        />

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

据我所知,我们不能如您所愿。

因为 TextInputLayout 被设计为在获得焦点后浮动提示因此,一旦它上升,占位符中就没有任何内容。我们可以按照您的要求进行如下略微更改。

<?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"
    android:gravity="center"
    tools:context="com.Whosebug.MainActivity">


    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingLeft="10dp"
        android:text="Label"
        android:textColor="@color/colorPrimary" />

    <android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp"
        android:paddingLeft="10dp"
        app:hintEnabled="false">

        <android.support.v7.widget.AppCompatEditText
            android:layout_width="match_parent"
            android:layout_height="?actionBarSize"
            android:hint="Place Holder"
            />

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

</RelativeLayout>

.

完美一个!!!

xml代码

<android.support.design.widget.TextInputLayout
        android:id="@+id/inputLayoutPhone"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="24dp"
        android:hint="Phone Number">

        <android.support.design.widget.TextInputEditText
            android:id="@+id/edtPhone"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="+91"
            android:inputType="phone" />
</android.support.design.widget.TextInputLayout>

Kotlin 代码

 edtPhone.hint=""
 edtPhone.onFocusChangeListener = View.OnFocusChangeListener { _, hasFocus ->
        inputLayoutPhone.isHintEnabled = hasFocus
        if(hasFocus){
            edtPhone.hint="+91"
        }else{
            edtPhone.hint= "Phone Number"
        }
    }

Java代码

edtPhone.setHint("");
    edtPhone.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View view, boolean hasFocus) {
            if (hasFocus){
                edtPhone.setHint("+91");
            }else{
                edtPhone.setHint("Phone Number");
            }

        }
    });

尝试为 AppCompatEditText 和 TextInputLayout 分别设置提示:

xml代码:

<android.support.design.widget.TextInputLayout
            android:id="@+id/inputLayoutPhone"
        ...>

        <android.support.design.widget.TextInputEditText
            android:id="@+id/edtPhone"
            ... />
</android.support.design.widget.TextInputLayout>

Kotlin 代码:

inputLayoutPhone.setHint("Label")
edtPhone.setHint("Placeholder")

现在 material 组件 (alpha03) 支持占位符文本:

  dependencies {
    // ...
    implementation 'com.google.android.material:material:1.2.0-alpha03'
    // ...
  }

  <com.google.android.material.textfield.TextInputLayout
      ...
      app:placeholderText="Placeholder text">
