Question

我试图添加一个Canvas,把图像带入我的碎裂。

DrawMap.java extends View and includes my onDraw(Canvas c). First I m trying to call this method every time the onLocationChanged is called. This means that the Canvas needs to be recalled/updated. How do I do that?

这里是另一回事。我试图把Canvas与红pic混为一谈。下面图是:

c.drawBitmap(resizedBitmap, newX, newY, paint);

在这里,我 app倒了我的 app,应该把信 add添加到支架中:

DrawMap d = new DrawMap(this);

FrameLayout frame_map = (FrameLayout) findViewById(R.id.frame_map);
frame_map.addView(d);
setContentView(frame_map);

Im利用两种微粒分解屏幕。左边(图)应显示地图,右边(图形)显示相关信息(可操作)。

What am I doing wrong? Thanks.

Answer 1

我认为,问题在于:<条码>、定型号(范围_map);。如果frame_map is the child of a parent view,则必须通过框架_map s parent view as the para amount for setContentView(View view);。

这只是对你的法典进行模拟的推论。因此,我要求从你错误报告中获得一些补充资料,以提供明确的解决办法。
