如何在 Android 中的 EditText 上設置自定義字體？

Question

我正在嘗試在EditText上實現自定義字體。 有沒有人有比我目前正在做的更好的方法？

Typeface myFont = Typeface.createFromAsset(getAssets(), "fonts/myfont.ttf");
edittext.setTypeface(myFont);

因為我有很多EditText ......

public class CEditText extends EditText {


    private Context context;
    private AttributeSet attrs;
    private int defStyle;

    public CEditText(Context context) {
        super(context);
        this.context=context;
        init();
    } 

     public CEditText(Context context, AttributeSet attrs) {
          super(context, attrs);
          this.context=context;
          this.attrs=attrs;
          init();
     }

    public CEditText(Context context, AttributeSet attrs, int defStyle) {
          super(context, attrs, defStyle);
          this.context=context;
          this.attrs=attrs;
          this.defStyle=defStyle;
          init();
    }

    private void init() {
          Typeface font=Typeface.createFromAsset(getContext().getAssets(), "fonts/myfont.ttf");
          this.setTypeface(font);
    }
    @Override
    public void setTypeface(Typeface tf, int style) {
        tf=Typeface.createFromAsset(getContext().getAssets(), "fonts/myfont.ttf");
        super.setTypeface(tf, style);
    }

    @Override
    public void setTypeface(Typeface tf) {
        tf=Typeface.createFromAsset(getContext().getAssets(), "fonts/myfont.ttf");
        super.setTypeface(tf);
    }

在 XML 中調用這個類如下

<yourpackagename.CEditText  android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="20dp">
</yourpackagename.CEditText>

Answer 2

創建一個擴展EditText的新類，例如

public class CustomEditTextNormal extends EditText
{

  public CustomEditTextNormal(Context context)
  {
      super(context);
      init(context);
  }

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

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

  protected void onDraw(Canvas canvas)
  {
    super.onDraw(canvas);
  }

  public void init(Context context)
  {
    try
    {
        Typeface myFont = Typeface.createFromAsset(context.getAssets(), "fonts/myfont.ttf");

        setTypeface(mSearchAndSend.HelveticaLight);
    }
    catch (Exception e)
    {
        Logger.LogError(e);
    }
  }
}

並將其包含在您的 XML 中，例如

<com.package.name.CustomEditText/>

如何創建一個繼承 EditText 的新類並設置您想要的字體，然后在 xml 中實例化新類？

Answer 4

創建一個繼承自EditText的新類，然后覆蓋public void setTypeface(Typeface tf, int style)方法並添加您自己的字體。

Answer 5

您需要在 Common 類中創建一個方法，例如，

public void setExternalFonts(EdiText tv) {
  Typeface tf = Typeface.createFromAsset(context.getAssets(),
            "fonts/myfont.ttf");
  tv.setTypeface(tf);
}

現在將此方法稱為

yourClassName.setExternalFonts(yourEditText);

Answer 6

創建一個繼承自 EditText 的新類，然后覆蓋 public void setTypeface(Typeface tf, int style) 方法並添加您自己的字體。

並在您的活動中像這樣 FontLoader.setQuickSandTypeface(YourEditText) 在您的活動中使用

Answer 7

試試這個

public void overrideFonts(final Context context, final View v) {
    try {
        if (v instanceof ViewGroup) {
            ViewGroup vg = (ViewGroup) v;
            for (int i = 0; i < vg.getChildCount(); i++) {
                View child = vg.getChildAt(i);
                overrideFonts(context, child);
            }
        } else if (v instanceof EditText) {
            ((EditText) v).setTypeface(Typeface.createFromAsset(context.getAssets(), "roboto_thin.ttf"));
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Answer 8

嘗試這個。 對按鈕、TextViews 也很有用。無論如何！

<your.namespace.app.FontEditText
     app:font="montserrat"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"/>

怎么可能？ 這邊走！

public class FontEditText extends EditText {

public FontEditText(Context context) {
    this( context, null );
}

public FontEditText(Context context, AttributeSet attrs) {
    this( context, attrs, 0 );
    init( context, attrs );
}

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

public FontEditText(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
    super( context, attrs, defStyleAttr, defStyleRes );
    init( context, attrs );
}

private void init(Context context, AttributeSet attrs) {
    TypedArray ta = context.obtainStyledAttributes( attrs, R.styleable.Fonts );

    if ( ta != null ) {
        String fontAsset = ta.getString( R.styleable.Fonts_font );
        if ( !StringUtils.isEmpty( fontAsset ) ) {
            int type = Integer.parseInt( fontAsset );

            Typeface typeFace = FontManager.getInstance( context ).getByType( type );
            ta.recycle();
            super.setTypeface( typeFace );
        }
    }
}

}

public class FontManager {

private static FontManager Instance;

private Context context;

private Typeface robotoCondensedBold;
private Typeface robotoCondensed;
private Typeface robotoLight;
private Typeface kronica;
private Typeface montserrat;
private Typeface montserratLight;
private Typeface keepCalmMedium;

private FontManager(Context context) {
    this.context = context;
    this.robotoCondensedBold = Typeface.createFromAsset( context.getAssets(), "fonts/RobotoCondensed-Bold.ttf" );
    this.robotoCondensed = Typeface.createFromAsset( context.getAssets(), "fonts/RobotoCondensed-Regular.ttf" );
    this.robotoLight = Typeface.createFromAsset( context.getAssets(), "fonts/Roboto-Light.ttf" );
    this.kronica = Typeface.createFromAsset( context.getAssets(), "fonts/kronika.ttf" );
    this.montserrat = Typeface.createFromAsset( context.getAssets(), "fonts/Montserrat-Regular.ttf" );
    this.montserratLight = Typeface.createFromAsset( context.getAssets(), "fonts/Montserrat-Light.ttf" );
    this.keepCalmMedium = Typeface.createFromAsset( context.getAssets(), "fonts/KeepCalmMedium.ttf" );
}

public synchronized static FontManager getInstance(Context context) {
    if ( Instance == null )
        Instance = new FontManager( context );

    return Instance;
}

public Typeface getByType(int type) {
    switch ( type ) {
        case 0:
            return FontManager.getInstance( context ).getRobotoCondensedBold();
        case 1:
            return FontManager.getInstance( context ).getRobotoLight();
        case 2:
            return FontManager.getInstance( context ).getKronica();
        case 3:
            return FontManager.getInstance( context ).getRobotoCondensed();
        case 4:
            return FontManager.getInstance( context ).getMontserrat();
        case 5:
            return FontManager.getInstance( context ).getMontserratLight();
        case 6:
            return FontManager.getInstance( context ).getKeepCalmMedium();
        default:
            return Typeface.DEFAULT;
    }
}

public Typeface getRobotoCondensedBold() {
    return robotoCondensedBold;
}

public Typeface getKronica() {
    return kronica;
}

public Typeface getRobotoCondensed() {
    return robotoCondensed;
}

public Typeface getRobotoLight() {
    return robotoLight;
}

public Typeface getMontserrat() {
    return montserrat;
}

public Typeface getMontserratLight() {
    return montserratLight;
}

public Typeface getKeepCalmMedium() {
    return keepCalmMedium;
}

此外，您的res文件夾中有一個font_attrs.xml ：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <declare-styleable name="Fonts">
        <attr name="font" format="enum">
            <enum name="robotoCondensedBold" value="0"/>
            <enum name="robotoLight" value="1"/>
            <enum name="kronica" value="2"/>
            <enum name="robotoCondensed" value="3"/>
            <enum name="montserrat" value="4"/>
            <enum name="montserratLight" value="5"/>
            <enum name="keepCalmMedium" value="6"/>
        </attr>
    </declare-styleable>
</resources> 

請注意，您只需要修改FontManager和font_attrs.xml即可自定義您的字體！
