android studio 找不到自定义字体文件

Question

I am using a simple TextView in my activity and want to make it appear in a custom font 'Black Chancery'. I have put the blkchcry.ttf file at location app>src>main>assets>fonts>blkchcry.ttf . But, the android studio can't find that font. Here's my AboutusActivity.java code

public class AboutusActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_aboutus);

    TextView tx = (TextView)findViewById(R.id.title);
    Typeface custom_font = Typeface.createFromAsset(getAssets(),  "fonts/blkchcry.ttf");
    tx.setTypeface(custom_font);
    }
}

and following is the activity_aboutus.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".AboutusActivity">

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/title"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="About Rathi Classes"
        android:textSize="20sp"
        android:layout_margin="10dp"
        android:gravity="center_horizontal"/>

    <TextView
        android:layout_below="@+id/title"
        android:id="@+id/description"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:text="@string/about_text"
        android:textSize="20sp"
        android:layout_margin="10dp" />

</RelativeLayout>

and here is the logcat

I have tried cleaning the project but it failed to resolve the problem. Please help.

Answer 1

Change the location your blkchcry.tttf from

app>src>main>assets>fonts>blkchcry.ttf.

to

app>src>main>res>font>blkchry.tff

And here's the fun part, you need to create a custom font file inside the same folder. Name it as my_font.xml

That's called Creating a Font Family

If you're using multiple versions of the same font, then you may want to group them together into a font family. A font family is essentially a dedicated XML file where you define each version of the font, along with its associated style and weight attributes.

Here's a demo font file

[ Update ] which you can simply paste coz I updated the contents.

<?xml version="1.0" encoding="utf-8"?>
<font-family xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools">

    <font
        android:font="@font/blkchry"
        android:fontStyle="normal"
        android:fontWeight="400"
        app:font="@font/blkchry"
        app:fontStyle="normal"
        app:fontWeight="400"
        tools:ignore="UnusedAttribute" />

</font-family>

Because getAssets() will look for an .xml file, not .tff even though you mentioned .tff file in your code.

Answer 2

Paste Font here like this and also make your font name in small case :-

app  > src > main > assets > fonts > blkchry.tff

set Font in java File like this :-

public class AboutusActivity extends Activity {
 Context mContext;
 Typeface fontblkchry;

 @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mContext = this;
    setContentView(R.layout.activity_about_us);

      fontblkchry = Typeface.createFromAsset(mContext.getAssets(), "fonts/blkchry.ttf");
      textview1.setTypeface(fontblkchry);
    }
}

Answer 3

Change your location:

from

app>src>main>assets>fonts>blkchcry.ttf.

to

app>src>main>res>font>blkchry.tff

then change your typeface:

 Typeface typeface = getResources().getFont(R.font.blkchcry); textView.setTypeface(typeface);

Answer 4

In my case, I was adding a font with Capital Letters and some symbols like -(hyphen). Try renaming the fonts. So, just make all letters small, replace hyphen with underscore _
