Question

我在android studio中尝试了一些东西，我意识到它不能在Android 5.0或6.0上运行，它只能在7.0上运行。我正在使用compileSdkVersion 26，minSdkVersion 21和targetSdkVersion 26所以它应该没有任何问题。我不明白logcat的错误。有人可以帮帮我吗？

由于

这是代码：

public class Juego extends SurfaceView {

Personaje personaje;
Paint paint;

public Juego(Context context, AttributeSet attrs) {
    super(context, attrs);

    paint = new Paint();

    Drawable image = context.getResources().getDrawable(R.drawable.image);

    Bitmap bitmap = ((BitmapDrawable) image).getBitmap();

    personaje = new Personaje(this, bitmap);

}

public void onDraw(Canvas canvas){

    paint.setColor(Color.BLACK);
    canvas.drawRect(0, 0, canvas.getWidth(), canvas.getHeight(), paint);

    personaje.onDraw(canvas);
    invalidate();
}

}

Personaje：

public class Personaje {

private Juego juego;
private Bitmap personaje;
Paint paint;

int x, y, inicio = 0, ancho, alto, currentFrame = 0,Horizontal = 1, Vertical = 8, frameLengthInMilliseconds = 150, cantFrames = 8;
long fps, timeThisFrame, lastFrameChangeTime = 0;


public Personaje(Juego juego, Bitmap personaje){

    this.juego = juego;
    this.personaje = personaje;
    this.ancho = personaje.getWidth() / Vertical;
    this.alto = personaje.getHeight() / Horizontal;

    paint = new Paint();
}

private void update() {

    long startFrame = System.currentTimeMillis();

    if (startFrame > lastFrameChangeTime + frameLengthInMilliseconds) {
        lastFrameChangeTime = startFrame;
        currentFrame++;
        if (currentFrame >= cantFrames) {

            currentFrame = 0;
        }
    }

    long startFrameTime = System.currentTimeMillis();

    timeThisFrame = System.currentTimeMillis() - startFrameTime;
    if (timeThisFrame >= 1) {
        fps = 1000 / timeThisFrame;
    }
}

public void onDraw(Canvas canvas) {

    update();

    int srcX = currentFrame * ancho;
    int srcY = alto * inicio;

    x = canvas.getWidth()/2;
    y = canvas.getHeight()/2;

    Rect src = new Rect(srcX, srcY, srcX + ancho, srcY + alto);
    Rect dst = new Rect(x, y, x + ancho, y + alto);

    canvas.drawBitmap(personaje, src, dst, null);
}

}

logcat的：

Answer 1

查看堆栈跟踪，这似乎是实际问题：

引起：android.content.res.Resources $ NotFoundException：资源ID＃0x7f060055

可能由以下原因引起：

Drawable image = context.getResources().getDrawable(R.drawable.image);

你应该可以检查我的开场＆＃34; R.java＆＃34;并寻找分配为＃0x7f060055

的资源

api的问题
