问题描述

java.lang.IllegalArgumentException: x 一定要小于 bitmap.width()

获取屏幕截图，用裁剪图片创建位图的时候出现了错误，

先看看我的代码吧：

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());

日志也看一下：

11-01 11:00:31.419: I/System.out(1658): vListView :- 60        11-01 11:00:31.429: I/System.out(1658): hListView :- 60        11-01 11:00:31.429: I/System.out(1658): Width :- 480        11-01 11:00:31.429: I/System.out(1658): Height :- 320        11-01 11:00:31.429: D/AndroidRuntime(1658): Shutting down VM        11-01 11:00:31.429: W/dalvikvm(1658): threadid=1: thread exiting with uncaught exception  (group=0x40018560)        11-01 11:00:31.429: E/AndroidRuntime(1658): FATAL EXCEPTION: main        11-01 11:00:31.429: E/AndroidRuntime(1658): java.lang.IllegalArgumentException: x + width  must be <= bitmap.width()        11-01 11:00:31.429: E/AndroidRuntime(1658):     at android.graphics.Bitmap.createBitmap(Bitmap.java:410)        11-01 11:00:31.429: E/AndroidRuntime(1658):     at android.graphics.Bitmap.createBitmap(Bitmap.java:383)        11-01 11:00:31.429: E/AndroidRuntime(1658):     at com.appsehs.android.CUTECRAZYKITTENDRESSUPGAME.PhotoSortrActivity.takeScreenShot(PhotoSortrActivity.java:247)        11-01 11:00:31.429: E/AndroidRuntime(1658):     at com.appsehs.android.CUTECRAZYKITTENDRESSUPGAME.PhotoSortrActivity.onOptionsItemSelected(PhotoSortrActivity.java:274)        11-01 11:00:31.429: E/AndroidRuntime(1658):     at android.app.Activity.onMenuItemSelected(Activity.java:2205)

程序里面x < bitmap.getWidth也就是60 < 480

但是报错了

解决方案

Bitmap createBitmap (Bitmap source int x int y int width int height)
x + width must equal or less than source.getWidth() in your case 60 + 480 > 480 so error occur.
