如何设置图片的大小？

I have 飞溅.png并希望该图像全部出现在屏幕上，就像fitXY for ImageView. 飞溅.png尺寸为 480x767。

我必须在代码中更改什么？

public class BitmapConfigView extends LinearLayout {
private Bitmap mImage;
private Paint mPaint = new Paint();

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

    BitmapFactory.Options opts = new BitmapFactory.Options();
    opts.inPreferredConfig = Bitmap.Config.ARGB_8888;
    opts.inScaled = false;
    mImage = BitmapFactory.decodeResource( getResources(), R.drawable.splash, opts);

    mPaint.setDither(true);
    setWillNotDraw(false);
    setOrientation(VERTICAL);
    setGravity(Gravity.BOTTOM);
}

@Override
protected void onDraw(Canvas canvas) {
    canvas.drawBitmap(mImage, 0.0f, 0.0f, mPaint);
}
}

缩放位图。这就是您正在寻找的：
