Question

我有一个嵌入片段的 activity_edit_profile.xml 布局，但EditText提示会一直显示。当EditText字段处于焦点或插入文本时，如何摆脱提示？

    <?xml version="1.0" encoding="utf-8"?>
        <android.support.design.widget.CoordinatorLayout
            xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:tools="http://schemas.android.com/tools"
            android:id="@+id/DrawerLayout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            tools:context="com.getbase.floatingactionbutton.sample.EditProfileActivity"
            tools:ignore="MergeRootFrame">

            <include layout="@layout/fragment_edit_profile"/>

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

在 fragment_edit_profile.xml

中

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

editText提示与textInput一起显示和重叠。

这里是TextLabel样式：

<style name="TextLabel" parent="@android:style/TextAppearance">
    <item name="android:textColorHint">@color/half_black</item>
    <item name="android:textSize">14dp</item>
    <item name="colorAccent">@color/ColorPrimary</item>
    <item name="colorControlActivated">@color/ColorPrimary</item>
</style>

Answer 1

您可以将focusChangeListener附加到EditText字段。

我们以First Name为例。为其分配ID firstName。现在，当它进入焦点时，将提示文本设置为空字符串。当它失去焦点时，将提示文本更改回First Name：

EditText firstName = (EditText)findViewById(R.id.firstName);
firstName.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    public void onFocusChange(View v, boolean hasFocus) {
        if(hasFocus) {
            firstName.setHint("");
        }
        else {
            firstName.setHint("First Name");
        }
    }
});

Answer 2

可能问题在于您为TextInputLayout所设置的主题设置的主题应该是什么样的 -

    <style name="AppTheme.EditText">
        <item name="colorPrimary">#FF4081</item>
        <item name="colorPrimaryDark">#3F51B5</item>
        <item name="colorAccent">#303F9F</item>
    </style>

Answer 3

删除TextInputLayout小部件。仅添加EditText。

   <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="First Name"
            android:inputType="textCapWords"
            android:nextFocusDown="@+id/register_input_lastname"
            />

EditText提示继续显示
