如何在Android中的TextView上使用自定义字体

Question

For implementing custom font i seen few examples here issue is different,I am taking custom font in one abstract class which is used in all over the application.i am unable to change the fonts. thanks in advance.

Answer 1

Create the custom class like below.

public class CustomTextView extends TextView {

    public CustomTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        init(attrs);
    }

    public CustomTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init(attrs);

    }

    public CustomTextView(Context context) {
        super(context);
        init(null);
    }

    private void init(AttributeSet attrs) {
        if (attrs!=null) {
             TypedArray a = getContext().obtainStyledAttributes(attrs, R.styleable.CustomTextView);
             String fontName = a.getString(R.styleable.CustomTextView_fontName);
             if (fontName!=null) {
                 Typeface myTypeface = Typeface.createFromAsset(getContext().getAssets(), "fonts/"+fontName);
                 setTypeface(myTypeface);
             }
             a.recycle();
        }
    }

}

and add your font in assets>fonts folder.

add following in attrs.xml

<declare-styleable name="CustomTextView">
        <attr name="fontName" format="string" />
    </declare-styleable>

to use.

<com.abc.cusomclass.CustomTextView 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    app:fontName="/*name of your font from assets/font folder*/"/>

Answer 2

You can do like this. You have to add your .tff file on the assets folder

ArialMTBoldRegularTextView.java:

public final class ArialMTBoldRegularTextView extends CustomTextView {

    public static final String FONT_PATH = "arial-rounded-mt-bold.ttf";

    public ArialMTBoldRegularTextView(Context context) {
        super(context);
        setFont(FONT_PATH);
    }

    public ArialMTBoldRegularTextView(Context context, AttributeSet attributeSet) {
        super(context, attributeSet);
        setFont(FONT_PATH);
    }

    public ArialMTBoldRegularTextView(Context context, AttributeSet attributeSet, int defStyleAttr) {
        super(context, attributeSet, defStyleAttr);
        setFont(FONT_PATH);
    }

    public void setFont(String fontPath) {
        changeFont(this, fontPath);
    }



public static void changeFont(final CompoundButton button, final String fontPath) {
    Typeface typeface = Typeface.createFromAsset(button.getContext().getAssets(), fontPath);
    button.setTypeface(typeface);
}
}

CustomTextView.java

public class CustomTextView extends TextView {

    public CustomTextView(Context context) {
        super(context);
    }

    public CustomTextView(Context context, AttributeSet attributeSet) {
        super(context, attributeSet);
    }

    public CustomTextView(Context context, AttributeSet attributeSet, int defStyleAttr) {
        super(context, attributeSet, defStyleAttr);
    }

    public Typeface getFont(final Context context, final String fontPath) {
        return Typeface.createFromAsset(context.getAssets(), fontPath);
    }

    public void changeFont(final TextView textView, final String fontPath) {
        Typeface typeface = Typeface.createFromAsset(textView.getContext().getAssets(), fontPath);
        textView.setTypeface(typeface);
    }

    public void changeFont(final CompoundButton button, final String fontPath) {
        Typeface typeface = Typeface.createFromAsset(button.getContext().getAssets(), fontPath);
        button.setTypeface(typeface);
    }
}

and fater in xml:

<packagename.views.ArialMTBoldRegularTextView
            android:layout_width="wrap_content"
            android:layout_height="35dp"
            android:gravity="center"
            android:text="Pseudo"/>

Answer 3

try this for custom font fron Assets

// Font path
        String fontPath = "fonts/Face Your Fears.ttf";

        // text view label
        TextView txtGhost = (TextView) findViewById(R.id.ghost);

        // Loading Font Face
        Typeface tf = Typeface.createFromAsset(getAssets(), fontPath);

        // Applying font
        txtGhost.setTypeface(tf);

现在android支持库26支持直接从XML使用字体。有关更多详细信息，请参阅文档 。

Answer 5

The better way of doing this is to make custom TextView with custom font like this:

Java

import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.widget.TextView;


public class RegularProximaTextView extends TextView {
   public static Typeface FONT_NAME;


   public RegularProximaTextView(Context context) {
    super(context);
    if(FONT_NAME == null) FONT_NAME = 
  Typeface.createFromAsset(context.getAssets(), "fonts/Mark Simonson - 
  Proxima Nova Regular.otf");
    this.setTypeface(FONT_NAME);
  }
  public RegularProximaTextView(Context context, AttributeSet attrs) {
    super(context, attrs);
     if(FONT_NAME == null) FONT_NAME = 
    Typeface.createFromAsset(context.getAssets(), "fonts/Mark Simonson - 
      Proxima 
      Nova Regular.otf");
      this.setTypeface(FONT_NAME);
   }
  public RegularProximaTextView(Context context, AttributeSet attrs, int 
  defStyle) {
    super(context, attrs, defStyle);
    if(FONT_NAME == null) FONT_NAME = 
       Typeface.createFromAsset(context.getAssets(), "fonts/Mark Simonson - 
       Proxima Nova Regular.otf");
       this.setTypeface(FONT_NAME);
    }
 }

XML

  <?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"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  android:id="@+id/activity_login"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:fitsSystemWindows="true"
  android:descendantFocusability="beforeDescendants"
  android:focusableInTouchMode="true"
  android:background="@color/colorGreyBar"
 >


   <com.tracer.joblogic.v2.helpers.custom_ui.RegularProximaTextView
            android:id="@+id/tvTextView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:visibility="gone"
            android:textColor="@color/colorButtonRed"
            android:text="Some text"
            android:textSize="8sp"
            />
 </android.support.design.widget.CoordinatorLayout>
