Android Studio自定义字体为标准/默认字体？

Question

I have my own font that I want to use for my app in all layouts, I want to change the default font for my app .

In styles.xml I can use

 <item name="android:fontFamily"></item>

to change the change the font, but how do I use my custom font here?

In App -> src -> main , i made a new directory called Assets , then another directory in that one called Fonts , and this is where i placed my custom font.

Is this possible? If so, how?

EDIT

As mayosk said, I added

compile 'uk.co.chrisjenx:calligraphy:2.2.0'

And made a Java Class that extends Application as shown below

public class CustomResources extends Application {

@Override
public void onCreate() {
    super.onCreate();

    CalligraphyConfig.initDefault(new CalligraphyConfig.Builder()
            .setDefaultFontPath("fonts/din_light.ttf")
            .setFontAttrId(R.attr.fontPath)
            .build()
    );
}
}

But the font is still the same, did I miss something

Answer 1

Use caligraphy : https://github.com/chrisjenx/Calligraphy

Add dependency to your app build.gradle:

compile 'uk.co.chrisjenx:calligraphy:2.2.0'

and extend your application class where you need to add this code to onCreate method

CalligraphyConfig.initDefault(new CalligraphyConfig.Builder()
                        .setDefaultFontPath("Fonts/customFont.ttf")
                        .setFontAttrId(R.attr.fontPath)
                        .build()
        );

and also you need to override attachBaseContext method() in your activity:

@Override
protected void attachBaseContext(Context newBase) {
    super.attachBaseContext(CalligraphyContextWrapper.wrap(newBase));
}

Answer 2

First of all you need to create a base class which extends Textview , here is the baseclass

public class MyTextView extends TextView {
public MyTextView(Context context, AttributeSet attrs, int defStyle) {
    super(context, attrs, defStyle);
    setTypeFace(context);
}

public MyTextView(Context context, AttributeSet attrs) {
    super(context, attrs);
    setTypeFace(context);
}

public MyTextView(Context context) {
    super(context);
    setTypeFace(context);
}

private void setTypeFace(Context context) {
    setTypeface(Typeface.createFromAsset(getContext().getAssets(), "fonts/Lato-Bold.ttf"));
}}

later in xml

   <com.example.MyTextView
            android:id="@+id/text_view"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:text="hi" />

same for edittext also. By doing this all the textviews and edittexts have same font entire the app.

Answer 3

I have a special way to change the default font.I set a whole paint to create custom view and draw font on onDraw method，instead of xml way。 like this:

`private void initPaint(Context context)
{
    mTextPaint = new TextPaint();
    mTextPaint.setTextSize(66.46F);
    mTextPaint.setColor(Color.BLACK);

    Typeface typeface = Typeface.createFromAsset(context.getAssets(), "fonts/MFKeKe_Noncommercial-Regular.ttf");
    mTextPaint.setTypeface(typeface);
    mTextPaint.setTextSkewX(-0.5F);

}

@Override
protected void onDraw(Canvas canvas)
{
    super.onDraw(canvas);
    mStaticLayout = new StaticLayout(TEXT1,mTextPaint,canvas.getWidth(), Layout.Alignment.ALIGN_NORMAL,1.0F,0.0F,false);
    mStaticLayout.draw(canvas);
    canvas.restore();
}`
