android - Android，字体未复制到新油漆中

Question

在以下代码中：

Paint tPaint = new Paint(aPaint);
tPaint.setTypeface(typeFace);
aPaint =  new Paint(tPaint);

观察到 typeFace 设置为 tPaint，但是 typeFace 没有被复制到 aPaint 中。

Answer 1

这不完全是一个答案，而是一种解决方法。

我替换了： aPaint = new Paint(tPaint); 与：aPaint = newPaint(tPaint); 并创建了方法：

  public Paint newPaint(Paint fromPaint){
      Typeface tf = fromPaint.getTypeface();
      Paint rPaint = new Paint(fromPaint);
      rPaint.setTypeface(tf);
      return rPaint;
  }

这行得通。

Answer 2

好的，这就是我的代码的样子。看看能不能找到什么。

主视图.java

public class MainView extends View {
Context context;

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

@Override
protected void onDraw(Canvas canvas) {
    super.onDraw(canvas);

    Paint apaint = new Paint();
    apaint.setTextSize(100);
    apaint.setTypeface(Typeface.createFromAsset(context.getAssets(), "fonts/sketchblock.ttf"));

    canvas.drawText("Dusean", canvas.getWidth()/2, canvas.getHeight()/2, apaint);
    Paint tpaint = new Paint(apaint);

    canvas.drawText("Dusean", canvas.getWidth()/3, canvas.getHeight()/3, tpaint);
}
}

MainActivity.java

public class MainActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(new MainView(this));
}
}

和资产文件夹assets/fonts/font.ttf中的字体
