使用自定义字体是Android应用开发中常见的需求之一。通过将自定义字体设置为应用的默认字体，可以为应用增加独特的视觉效果，提升用户体验。本文将介绍如何在Android应用中将自定义字体设置为油漆，并提供相应的案例代码。

java
import android.content.Context;
import android.graphics.Typeface;
import android.widget.TextView;
public class FontUtil {
    private static Typeface paintTypeface;
    public static void setPaintTypeface(Context context, TextView textView) {
        if (paintTypeface == null) {
            paintTypeface = Typeface.createFromAsset(context.getAssets(), "font/paint.ttf");
        }
        textView.setTypeface(paintTypeface);
    }
}

xml
    android:id="@+id/customTextView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Hello Custom Font!"
    android:textSize="24sp"
    app:fontFamily="@font/paint" />

java
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
    private TextView customTextView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        customTextView = findViewById(R.id.customTextView);
        FontUtil.setPaintTypeface(this, customTextView);
    }
}
