有人试图改变浮标的字体吗?我更改了EditText的源代码,但浮动标签的字体没有改变,我非常感谢那些帮助我的人
码:
<android.support.design.widget.TextInputLayout
android:id="@+id/tilTextoDescricao"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="@id/tilValorUnidade"
android:layout_marginTop="10dp">
<EditText
android:id="@+id/etTextoDescricao"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:hint="Descrição"
android:textSize="15dp"
android:inputType="text" />
</android.support.design.widget.TextInputLayout>
-----------------
etTextoDescricao= (EditText) findViewById(R.id.etTextoDescricao);
etTextoDescricao.setTypeface(CustomTypeface.getTypefaceMediumDefault(this));
从Design Library v23
开始,你可以使用TextInputLayout#setTypeface()
。
这将在展开和浮动提示上设置字体。
这是在feature request上讨论的b.android.com。
编辑:错误视图字体没有设置,但现在fixed在v25.1.0
。
我正在寻找这个,我发现这样,使用支持库:
Documentation
并将此字体设置为TextInputLayout。
对我来说就像魅力一样,我希望它能帮助别人=]

使用可以使用如下所示的style.xml:

不幸的是,你必须使用反射来处理这个问题。
浮动标签由CollapsingTextHelper
绘制,TypefaceSpan
是一个内部的包私有类,并不设置为处理跨度。所以,在这种情况下,使用像自定义final Typeface tf = Typeface.createFromAsset(getAssets(), "your_custom_font.ttf");
final TextInputLayout til = (TextInputLayout) findViewById(R.id.yourTextInputLayout);
til.getEditText().setTypeface(tf);
try {
// Retrieve the CollapsingTextHelper Field
final Field cthf = til.getClass().getDeclaredField("mCollapsingTextHelper");
cthf.setAccessible(true);
// Retrieve an instance of CollapsingTextHelper and its TextPaint
final Object cth = cthf.get(til);
final Field tpf = cth.getClass().getDeclaredField("mTextPaint");
tpf.setAccessible(true);
// Apply your Typeface to the CollapsingTextHelper TextPaint
((TextPaint) tpf.get(cth)).setTypeface(tf);
} catch (Exception ignored) {
// Nothing to do
}
这样的东西是行不通的。
因为它使用反射,所以不保证将来可以使用。
履行
TextView
错误视图
如果您需要更改错误的字体,可以执行以下两项操作之一:
Typeface
并像以前一样应用TextInputLayout
TextView
使用的错误视图只是一个final Field errorField = til.getClass().getDeclaredField("mErrorView");
errorField.setAccessible(true);
((TextView) errorField.get(til)).setTypeface(tf);
,因此它能够处理跨度。用反射
final SpannableString ss = new SpannableString("Error");
ss.setSpan(new FontSpan(tf), 0, ss.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
til.setError(ss);
private static final class FontSpan extends MetricAffectingSpan {
private final Typeface mNewFont;
private FontSpan(Typeface newFont) {
mNewFont = newFont;
}
@Override
public void updateDrawState(TextPaint ds) {
ds.setTypeface(mNewFont);
}
@Override
public void updateMeasureState(TextPaint paint) {
paint.setTypeface(mNewFont);
}
}
使用自定义范围

结果
我使用的字体是MaterialComponents
。
我正在使用新的<style name="AppTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
...
<item name="textInputStyle">@style/CustomFontTextInputLayout</item>
</style>
<!-- region TextInputLayout & TextInputEditText styles -->
<style name="TextInputLayout.OutlineBox.CustomFont" parent="Widget.MaterialComponents.TextInputLayout.OutlinedBox">
<item name="android:theme">@style/ThemeOverlay.TextInputEditText.OutlinedBox.CustomFont</item>
</style>
<style name="ThemeOverlay.TextInputEditText.OutlinedBox.CustomFont" parent="ThemeOverlay.MaterialComponents.TextInputEditText.OutlinedBox">
<item name="editTextStyle">@style/TextInputEditText.OutlinedBox.CustomFont</item>
</style>
<style name="TextInputEditText.OutlinedBox.CustomFont" parent="Widget.MaterialComponents.TextInputEditText.OutlinedBox">
<item name="android:fontFamily">@font/my_font</item>
</style>
<style name="CustomFontTextInputLayout" parent="Widget.Design.TextInputLayout">
<item name="hintTextAppearance">@style/TextInputLayoutHintText</item>
<item name="helperTextTextAppearance">@style/TextInputLayoutHelperText</item>

主题,没有一个答案帮助了我。
不得不自己玩风格和主题。将发布一大块样式,以防有人面临同样的问题。
<android.support.design.widget.TextInputLayout
style="@style/TextInputLayout.OutlineBox.CustomFont"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.TextInputEditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/first_name"/>
</android.support.design.widget.TextInputLayout>
然后在xml布局中:
这是结果:
<android.support.design.widget.TextInputLayout
android:id="@+id/text_input1"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:id="@+id/edt_user"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/username"/>
</android.support.design.widget.TextInputLayout>
我刚刚找到一个简单的解决方案,它对我有用:
通过这种方式,您可以将字体设置为任何编辑文本的提示:
在layout.xml中:
public class MainActivity extends AppCompatActivity {
EditText editText;
TextInputLayout textInputLayout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Typeface font_yekan= Typeface.createFromAsset(getAssets(), "fonts/byekan.ttf");
textInputLayout= (TextInputLayout) findViewById(R.id.text_input1);
textInputLayout.setTypeface(font_yekan);
}
}
在java类中:
adneal's answer
这是public class CustomTextInputLayout extends TextInputLayout {
public CustomTextInputLayout(Context context) {
super(context);
initFont(context);
}
public CustomTextInputLayout(Context context, AttributeSet attrs) {
super(context, attrs);
initFont(context);
}
private void initFont(Context context) {
final Typeface typeface = Typeface.createFromAsset(
context.getAssets(), "fonts/YOUR_CUSTOM_FONT.ttf");
EditText editText = getEditText();
if (editText != null) {
editText.setTypeface(typeface);
}
try {
// Retrieve the CollapsingTextHelper Field
final Field cthf = TextInputLayout.class.getDeclaredField("mCollapsingTextHelper");
cthf.setAccessible(true);
// Retrieve an instance of CollapsingTextHelper and its TextPaint
final Object cth = cthf.get(this);
final Field tpf = cth.getClass().getDeclaredField("mTextPaint");
tpf.setAccessible(true);
// Apply your Typeface to the CollapsingTextHelper TextPaint
((TextPaint) tpf.get(cth)).setTypeface(typeface);
} catch (Exception ignored) {
// Nothing to do
}
}
}
的自定义类实现。
CustomTextInputLayout
在您的XML文件中,您现在需要使用TextInputLayout
而不是<your.package.CustomTextInputLayout
android:id="@+id/textInputLayout_email"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<AutoCompleteTextView
android:id="@+id/editText_email"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="@string/hint_email"
android:inputType="textEmailAddress" />
,它将开箱即用。
adneal
谢谢final Typeface tf = Typeface.createFromAsset(getAssets(), "your_custom_font.ttf");
final TextInputLayout til = (TextInputLayout) findViewById(R.id.yourTextInputLayout);
til.getEditText().setTypeface(tf);
til.setTypeface(tf);
的答案。
@Override
public void setErrorEnabled(boolean enabled) {
super.setErrorEnabled(enabled);
if (enabled) {
try {
Field cthf = TextInputLayout.class.getDeclaredField("mErrorView");
cthf.setAccessible(true);
TextView error = (TextView) cthf.get(this);
if (error != null)
error.setTypeface(tf);
} catch (Exception e) {
}
}
}
解决@adneal中的问题答案:如果setErrorEnabled未设置为true,则mErrorView将为null,如果在任何时候将其设置为false,则字体将更改回默认值。所以解决它:
在您自定义TextInputLayout覆盖setErrorEnabled
<style name="customfontstyle" parent="@android:style/TextAppearance.Small">
<item name="android:fontFamily">@font/poppins_regular</item>
</style>
有一种更简单的方法,
在名为“font”的“res”文件夹中创建一个新目录,并在其中放置一个字体。然后打开“样式”文件并创建一个新样式:
<android.support.design.widget.TextInputLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:hintTextAppearance="@style/customfontstyle"
>
<android.support.design.widget.TextInputEditText
android:layout_width="220dp"
android:layout_height="wrap_content"
android:id="@+id/edit_phone_number"
android:hint="@string/phone_number_label"
android:inputType="number"
/>
</android.support.design.widget.TextInputLayout>
您还可以添加更多属性,例如textColor,textSize等。
然后在你的XML中:
edit_login_emailOrPhone.setOnFocusChangeListener(new View.OnFocusChangeListener() {
@Override
public void onFocusChange(View v, boolean hasFocus) {
if(hasFocus)
{
textInputLayout_login_emailOrPhone.setTypeface(APSApplication.getInstance().getFonts().getTypefaceSemiBold());
}else
{
textInputLayout_login_emailOrPhone.setTypeface(APSApplication.getInstance().getFonts().getTypefaceRegular());
}
}
});
我检查了它,它的工作原理。
这就是我实现这一目标的方式
Typeface typeface = ResourcesCompat.getFont(context, R.font.myfont);
