【问题描述】:
我在截屏和创建带有裁剪图片的位图时出错
下面是我的代码
View v1 = mKittyBGLayer.getRootView();
v1.setDrawingCacheEnabled(true);
Bitmap source = v1.getDrawingCache();
int width = source.getWidth();
int height = source.getHeight();
System.out.println("vListView : -"+vListView.getWidth());
System.out.println("hListView : -"+hListView.getHeight());
System.out.println("Width : -"+width);
System.out.println("Height : -"+height);
bitmap = Bitmap.createBitmap(source, vListView.getWidth(), 0, width, height - hListView.getHeight());
我的 logcat 是
11-01 11:00:31.419: I/System.out(1658): vListView :- 60
11-01 11:00:31.429: I/System.out(1658): hListView :- 60

这里可以看到 x
虽然我遇到了错误
【问题讨论】:
-
您在哪个语句上得到了错误?
-
bitmap = Bitmap.createBitmap(source, vListView.getWidth(), 0, width, height - hListView.getHeight());
-
如果我做 bitmap = Bitmap.createBitmap(source, 0, 0, width, height - hListView.getHeight());它会工作
-
ok @Siddhpura 你的问题是你的 vListView.getWidth() 给出的宽度大于你的位图的宽度,所以它会抛出错误。明白我的意思。
