How to display bold text in a TextView in android

TextView widget display text on android app. we can render a TextView to display text as bold or italic both programmatically by java file and syntactically by xml layout file. we also can bold TextView text syntactically by using string ressource file. this first android app demonstrate us how can we render TextView text bold, italic, normal and even underlined by declarative syntax.

the android:textStyle attribute allow us to set the text style to normal, bold or italic. we can combine this style by separated them using keyboard pipe | symbol. so if we want to render TextView text as bold and italic then we need to set the android:textStyle attribute value as android:textStyle=»blod|italic». android:textStyle=»normal|italic» value display text as italic, android:textStyle=»bold» value display text only bold and android:textStyle=»normal» value define TextView text appearance as normal.

this is very interesting that we can render a TextView’s part of text as bold, italic or underlined by using string resource file. the string resource file allow us to declare a string resource which value contain html tags. so the final output show the stylish text on android app. strings.xml resource file exist under res/values folder.

in the following example code, we declare a string key value pair name stylish_text and its value. stylish_text key’s value contain html tags those make part of text bold, italic and underlined. in the xml layout file we can assign the string resource as android:text=»@string/stylish_text».

TextView bold text programmatically

the following android example app code demonstrate us how can we bold, italic or underline TextView text programmatically at run time in java file.

setTypeface() method allow us to set the typeface and style in which the text should be displayed in a widget. all Typeface families have not bold and italic variants. geTypeface() method allow us to get the current typeface and style in which the text is being displayed. we can define a TextView widget’s font and font variant by the setTypeface() method as setTypeface(Typeface.MONOSPACE, Typeface.BOLD_ITALIC). the setTypefce() method only render a TextView text to bold, italic and normal. it does not support underline text or any other formatting.

if we want to display bold and underlined text programmatically on an app, we need to take help the setText() method. to do this, we need to provide html tags with text as setText() method parameter. the setText() method render the html tags and display formatted text on application.

another way to render TextView text bold programmatically in java code by using style resource file. we can put a styles.xml file on res/values folder. then assign styles item and value to the style file. finally we can apply any style from this style file to the TextView by using the setTextAppearnce() method.

setTextAppearance() method allow us to set the text color, size, style, hint color etc from the specified TextAppearance resource.

Как изменить текст на жирный в Android?

Как изменить настройки текста / шрифта в Android TextView ?

Например, как вы делаете текст жирным ?

Для этого в layout.xml файле:

Программно метод состоит в следующем:

Устанавливает шрифт и стиль, в котором должен отображаться текст. Обратите внимание, что не во всех Typeface семьях есть варианты, выделенные жирным шрифтом и курсивом, поэтому вам, возможно, придется использовать их, setTypeface(Typeface, int) чтобы получить тот вид, который вам действительно нужен.

Просто вы можете сделать следующее:

Установите атрибут в XML

Программно метод заключается в:

Надеюсь, это поможет вам поблагодарить вас.

Вы можете использовать только определенные шрифты sans , serif и monospace через XML, код Java может использовать пользовательские шрифты

Программно (код Java)

Для случая, когда вы используете пользовательские шрифты, но не имеете жирного шрифта для шрифта, который вы можете использовать:

Это очень просто

Если вы рисуете это, то это сделает это:

В идеальном мире вы бы задали атрибут стиля текста в своем определении XML макета следующим образом:

Существует простой способ динамического достижения того же результата в вашем коде с помощью setTypeface метода. Вам нужно передать и объект класса Typeface , который будет описывать стиль шрифта для этого TextView. Таким образом, чтобы достичь того же результата, что и в приведенном выше определении XML, вы можете сделать следующее:

Первая строка создаст объект в предопределенном стиле (в данном случае Typeface.BOLD , но есть еще много ). Когда у нас есть экземпляр гарнитуры, мы можем установить его в TextView. И это все, что наш контент будет отображаться в стиле, который мы определили.

Я надеюсь, что это вам очень поможет. Для более подробной информации вы можете посетить

Из XML вы можете установить TextStyle к жирному шрифту , как показано ниже

С программной точки зрения, вы можете установить TextView жирным шрифтом, как показано ниже

Определите новый стиль с нужным форматом в файле style.xml в папке значений

Затем примените этот стиль к TextView, написав следующий код со свойствами TextView.

Material Design Buttons in Android with Example

Material Design Components (MDC Android) offers designers and developers a way to implement Material Design in their Android application. Developed by a core team of engineers and UX designers at Google, these components enable a reliable development workflow to build beautiful and functional Android applications. If you like the way how the UI elements from Google Material Design Components for android which are designed by Google are pretty awesome, then here are some steps that need to be followed to get them, and one of them is Google Material Design Components (MDC) Buttons.

1. Contained Button
2. Outlined Button
3. Text Button
4. Toggle Button

Below is a demo for all types of Buttons that we are going to create in this project.

Normal Contained Button behavior under dark theme.

Google MDC button behavior under dark theme.

Approach

Note that while syncing your project you need to be connected to the network and make sure that you are adding the dependency to the app-level Gradle file as shown below.

Step 3: Change the Base application theme

Go to app -> src -> main -> res -> values -> styles.xml and change the base application theme. The MaterialComponents contains various action bar theme styles, one may invoke any of the MaterialComponents action bar theme styles, except AppCompat styles.

Why the theme needs to be changed:
