我面临一个奇怪的问题,我有一个InputTextLayout和一个EditText,我正在努力实现这样的事情(如下图所示)(图片来自材料设计指南:https://material.io/guidelines/components/text-fields.html#text-fields-layout),其中有两个单独的提示。我这样做是通过添加android:hint两个布局。这样可以正常工作,但是当焦点偏离此时,"标签"向下移动并重叠"占位符"文本。 (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,我需要提供两种提示,以及"标签"不应该在焦点变化上下移。两个提示都应该保持在他们的位置
<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>

完美的一个!!!
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");
}
}
});

android:textColorHint="@color/white">
<EditText

android:layout_height="wrap_content"
android:hint="Placeholder"
android:inputType="text"
android:textColor="@color/white"
android:textColorHint="@color/white" />

仅在android:hint=""
或AppcompatEditText
TextInputLayout
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<android.support.v7.widget.AppCompatEditText

据我所知,我们无法按照您的意愿行事。
因为,TextInputLayout被设计为一旦它被聚焦就浮动提示所以,一旦它上升,就会在占位符中没有任何东西。我们可以通过以下略微更改来满足您的要求。
<?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.stackoverflow.MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingLeft="10dp"
android:text="Lable"
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>

尝试分别为AppCompatEditText和TextInputLayout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>
科特琳代码:
inputLayoutPhone.setHint("Label")
edtPhone.setHint("Placeholder")
