java - 自定义字体不起作用

Question

我目前正在制作一个基本动画教程。在我尝试在代码中包含自定义字体之前，该代码可以正常工作。我想知道是否有人能帮助我。下面我已经包含了 LogCat 和我的字体代码。

Typeface font;

public MyBringBack(Context context) {
    super(context);

    gPlus = BitmapFactory.decodeResource(getResources(), R.drawable.plusselected);
    changingY = 0;
    font = Typeface.createFromAsset(context.getAssets(), "G-Unit");

}


@Override
protected void onDraw(Canvas canvas) {
    // TODO Auto-generated method stub
    super.onDraw(canvas);
    canvas.drawColor(Color.WHITE);

    Paint textPaint = new Paint();
    textPaint.setARGB(50,254,10,500);
    textPaint.setTextAlign(Align.CENTER);
    textPaint.setTextSize(50);
    textPaint.setTypeface(font);
    canvas.drawText("mybringback",canvas.getWidth()/2, 200, textPaint);

LogCat:-

使用

font = Typeface.createFromAsset(context.getAssets(), "G-Unit.ttf");

相反

font = Typeface.createFromAsset(context.getAssets(), "G-Unit");

您需要将带有扩展名的字体文件名(如 ttf、otf...)作为第二个参数传递给 Typeface.createFromAsset 方法
