Question

Quiero usar el ícono de Font Awesome en mi aplicación de Android. Tengo algo de TextView para configurar esos íconos. No quiero usar ninguna imagen png. Mi Textview es así ->

<TextView
android:id="@+id/userLogin"
android:text="Login Now"
android:clickable="true"
android:onClick="login"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

No, quiero poner un icono antes del texto Iniciar sesión ahora. Como hacer eso ?

Answer 1

Puedes usar FontAwesome , solo declara en String.xml

<resources>
<string name="fa_icon_areachart">&#xf1fe;</string>
<string name="fa_icon_piechart">&#xf200;</string>
<string name="fa_icon_linechart">&#xf201;</string>
</resources>

Answer 2

Usando Typeface puedes establecerlo directamente por código

 mTypeFace = FontCache.get("font/GFont.ttf", getActivity());
mButtonQkView.setTypeface(mTypeFace);
mButtonQkView.setText(String.valueOf((char) 0xe907));

Para configurar el ícono de fuente como Leftdrawable, primero genere dibujable desde el ícono de fuente usando la clase TextDrawable

 TextDrawable gIcon = new TextDrawable(this);
gIcon.setTextSize(TypedValue.COMPLEX_UNIT_DIP, size);
gIcon.setTextAlign(Layout.Alignment.ALIGN_CENTER);
gIcon.setTypeface(FontCache.get(getString(R.string.icomoon), this));
gIcon.setText(String.valueOf((char) 0xe907));
gIcon.setTextColor(getResources().getColor(color));

Y establecerlo como izquierda dibujable

mButtonQkView.setCompoundDrawablesWithIntrinsicBounds(gIcon, null, null, null);

Answer 3

Puedes seguir esta respuesta .

Primero descargue el fontawesome.ttf desde aquí . Y ponga el archivo en asset / fontawesome.ttf .

A continuación, FontAwesome una clase FontAwesome que represente de hecho la vista de FontAwesome de FontAwesome .

public class FontAwesome extends TextView {
public FontAwesome(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public FontAwesome(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public FontAwesome(Context context) {
super(context);
init();
}
private void init() {
Typeface tf = Typeface.createFromAsset(getContext().getAssets(),
"/fontawesome.ttf");
setTypeface(tf);
}
}

ahora puede usar la clase Fontawesome como su necesidad y también seguir la hoja de trucos. para obtener el icono Unicode de tu icono.

Entonces, su vista de texto será así.

<PACKAGE_NAME.Fontawesome
android:id="@+id/userLogin"
android:text="&#xf007; Login Now"
android:clickable="true"
android:onClick="login"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

Answer 4

Estos son los pasos a seguir:

1. Primero descarga la fuente impresionante desde aquí: http://fontawesome.io/
2. Crear carpeta de activos y agregar fontawesome-webfont.ttf a esta carpeta
3. Crea una clase de ayuda por el siguiente código:

public class FontManager {
public static final String ROOT = "fonts/",
FONTAWESOME = ROOT + "fontawesome-webfont.ttf";
public static Typeface getTypeface(Context context, String font) {
return Typeface.createFromAsset(context.getAssets(), font);
}
}

4. Ahora usa la fuente impresionante para tu vista de texto usando el código a continuación

Typeface iconFont = FontManager.getTypeface(getApplicationContext(), FontManager.FONTAWESOME);
tvIcon1 = (TextView) findViewById(R.id.tvIcon1);
tvIcon2 = (TextView) findViewById(R.id.tvIcon2);
tvIcon3 = (TextView) findViewById(R.id.tvIcon3);
tvIcon1.setTypeface(iconFont);
tvIcon2.setTypeface(iconFont);
tvIcon3.setTypeface(iconFont);
