我认为您已经回答了自己的问题.为什么不呢?

I think you answered your question yourself. Why not:

public class DrawListenerView extends View{
    private Callback callback;
    public DrawListenerView(Callback callback){
        this.callback = callback;
    }

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

        //add your method here you want to call
        //Or use a Callback-pattern 
        callback.finish();
    } 
}

public interface Callback(){
    public void finish();
}

如果您查看来源:

上面的评论说

使整个视图无效.如果该视图可见，则将来会在某个时候调用onDraw(android.graphics.Canvas).必须从UI线程调用此方法.要从非UI线程进行调用，请调用postInvalidate().

Invalidate the whole view. If the view is visible, onDraw(android.graphics.Canvas) will >be called at some point in the future. This must be called from a UI thread. To call from >a non-UI thread, call postInvalidate().

尝试一下:)

可能您想使用回调来处理此问题.

probably you want to use a Callback to handle this.
