如何更改TextinputLayout的标签和edittext下划线android的颜色

Question

我正在使用android设计库TextinputLayout.但无法自定义提示颜色,标签颜色和EditText内部的下划线颜色TextinputLayout.请帮忙.

Answer 1

要更改底线颜色,您可以在应用主题中使用此颜色:

<item name="colorControlNormal">#c5c5c5</item>
<item name="colorControlActivated">@color/accent</item>
<item name="colorControlHighlight">@color/accent</item>

有关详细信息,请检查此线程.

更改浮动标签颜色

<style name="TextAppearance.App.TextInputLayout" parent="@android:style/TextAppearance">
<item name="android:textColor">@color/main_color</item>

并使用它像:

 <android.support.design.widget.TextInputLayout
  ...
   app:hintTextAppearance="@style/TextAppearance.App.TextInputLayout" >

更新:
并使用如下所示,如果您想要更改提示颜色,当它不是浮动标签时:

<android.support.design.widget.TextInputLayout
  ...
    app:hintTextAppearance="@style/TextAppearance.App.TextInputLayout"
    android:textColorHint="#c1c2c4">

通过材料组件库，您可以使用com.google.android.material.textfield.TextInputLayout.

您可以应用自定义样式来更改颜色。

要更改提示颜色，您必须使用以下属性：
hintTextColor和android:textColorHint.

<style name="Custom_textinputlayout_filledbox" parent="@style/Widget.MaterialComponents.TextInputLayout.FilledBox">
    <!-- The color of the label when it is collapsed and the text field is active -->
    <item name="hintTextColor">?attr/colorPrimary</item>

    <!-- The color of the label in all other text field states (such as resting and disabled) -->
    <item name="android:textColorHint">@color/selector_hint_text_color</item>
</style>

您应该为android:textColorHint. 就像是：

<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:alpha="0.38" android:color="?attr/colorOnSurface" android:state_enabled="false"/>
  <item android:alpha="0.6" android:color="?attr/colorOnSurface"/>
</selector>

要更改底线颜色，您必须使用属性：boxStrokeColor。

<style name="Custom_textinputlayout_filledbox" parent="@style/Widget.MaterialComponents.TextInputLayout.FilledBox">
    ....
    <item name="boxStrokeColor">@color/selector_stroke_color</item>
</style>

同样在这种情况下，您应该使用选择器。就像是：

<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:color="?attr/colorPrimary" android:state_focused="true"/>
  <item android:alpha="0.87" android:color="?attr/colorOnSurface" android:state_hovered="true"/>
  <item android:alpha="0.12" android:color="?attr/colorOnSurface" android:state_enabled="false"/>
  <item android:alpha="0.38" android:color="?attr/colorOnSurface"/>
</selector>

您还可以在布局中应用这些属性：

<com.google.android.material.textfield.TextInputLayout
    style="@style/Widget.MaterialComponents.TextInputLayout.FilledBox"
    app:boxStrokeColor="@color/selector_stroke_color"
    app:hintTextColor="?attr/colorPrimary"
    android:textColorHint="@color/selector_hint_text_color"
    ...>

基于Fedor Kazakov和其他人的回答,我创建了一个默认配置.

styles.xml

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

    <style name="Widget.Design.TextInputLayout" parent="AppTheme">
        <item name="hintTextAppearance">@style/AppTheme.TextFloatLabelAppearance</item>
        <item name="errorTextAppearance">@style/AppTheme.TextErrorAppearance</item>
        <item name="counterTextAppearance">@style/TextAppearance.Design.Counter</item>
        <item name="counterOverflowTextAppearance">@style/TextAppearance.Design.Counter.Overflow</item>
    </style>

    <style name="AppTheme.TextFloatLabelAppearance" parent="TextAppearance.Design.Hint">
        <!-- Floating label appearance here -->
        <item name="android:textColor">@color/colorAccent</item>
        <item name="android:textSize">20sp</item>
    </style>

    <style name="AppTheme.TextErrorAppearance" parent="TextAppearance.Design.Error">
        <!-- Error message appearance here -->
        <item name="android:textColor">#ff0000</item>
        <item name="android:textSize">20sp</item>
    </style>

</resources>

activity_layout.xml

<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="Text hint here"
        android:text="5,2" />

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

此博客文章描述了各种样式方面EditText和AutoCompleteTextView包装TextInputLayout.

对于EditText和AppCompat lib 22.1.0+,您可以使用一些与主题相关的设置来设置主题属性:

<style name="StyledTilEditTextTheme">
   <item name="android:imeOptions">actionNext</item>
   <item name="android:singleLine">true</item>
   <item name="colorControlNormal">@color/greyLight</item>
   <item name="colorControlActivated">@color/blue</item>
   <item name="android:textColorPrimary">@color/blue</item>
   <item name="android:textSize">@dimen/styledtil_edit_text_size</item>
</style>

<style name="StyledTilEditText">
    <item name="android:theme">@style/StyledTilEditTextTheme</item>
    <item name="android:paddingTop">4dp</item>
</style>

并应用于EditText:

<EditText
    android:id="@+id/etEditText"
    style="@style/StyledTilEditText"

因为AutoCompleteTextView事情更复杂,因为将其包装TextInputLayout并应用此主题会破坏浮动标签行为.您需要在代码中修复此问题:

private void setStyleForTextForAutoComplete(int color) {
    Drawable wrappedDrawable =     DrawableCompat.wrap(autoCompleteTextView.getBackground());
    DrawableCompat.setTint(wrappedDrawable, color);
    autoCompleteTextView.setBackgroundDrawable(wrappedDrawable);
}

并在Activity.onCreate:

setStyleForTextForAutoComplete(getResources().getColor(R.color.greyLight));
autoCompleteTextView.setOnFocusChangeListener((v, hasFocus) -> {
    if(hasFocus) {
        setStyleForTextForAutoComplete(getResources().getColor(R.color.blue));
    } else {
        if(autoCompleteTextView.getText().length() == 0) {  
              setStyleForTextForAutoComplete(getResources().getColor(R.color.greyLight));
        }
    }
});

Answer 5

在Edittext标签中添加此属性并享受:

 android:backgroundTint="@color/colorWhite"

Answer 6

ATextinputLayout不是一个视图，而是一个Layout，正如Dimitrios Tsigouris在他的博客文章中很好地描述的那样。因此，你不需要Style，这是Views唯一的，但使用Theme。在博客文章之后，我最终得到了以下解决方案：

开始在styles.xml与

<style name="TextInputLayoutAppearance" parent="Widget.Design.TextInputLayout">
        <!-- reference our hint & error styles -->
        <item name="android:textColor">@color/your_colour_here</item>
        <item name="android:textColorHint">@color/your_colour_here</item>
        <item name="colorControlNormal">@color/your_colour_here</item>
        <item name="colorControlActivated">@color/your_colour_here</item>
        <item name="colorControlHighlight">@color/your_colour_here</item>
</style>

并在您的布局中添加

<com.google.android.material.textfield.TextInputLayout
                android:theme="@style/TextInputLayoutAppearance"
...

Answer 7

<style name="Widget.Design.TextInputLayout" parent="android:Widget">
    <item name="hintTextAppearance">@style/TextAppearance.Design.Hint</item>
    <item name="errorTextAppearance">@style/TextAppearance.Design.Error</item>
</style>

您可以覆盖此样式以进行布局

您也可以更改内部 EditText-item 样式。

Answer 8

<style name="EditScreenTextInputLayoutStyle" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorControlNormal">@color/actionBar_background</item>
    <item name="colorControlActivated">@color/actionBar_background</item>
    <item name="colorControlHighlight">@color/actionBar_background</item>
    <item name="colorAccent">@color/actionBar_background</item>
    <item name="android:textColorHint">@color/actionBar_background</item>
</style>

将此样式应用于 TextInputLayout

Answer 9

如果你想改变酒吧/线条颜色提示文本颜色的TextInputLayout（什么口音的颜色通常是），然后就创建这个风格：

<style name="MyStyle">
    <item name="colorAccent">@color/your_color</item>
</style>

然后将其TextInputLayout作为主题应用：

<android.support.design.widget.TextInputLayout
    ...
    app:theme="@style/MyStyle" />

这基本上将一个主题（不是样式）设置为一个视图（而不是整个活动）。
