2 截取scrollview

// 测试输出

press(pressFormat.PNG, 100, out);
out.flush();
out.close();
}
} catch (IOException e) {
// TODO: handle exception
}
return bitmap;
}
3 截取ListView的屏幕方法
/**
* 截图listview
* **/
public static Bitmap getbBitmap(ListView listView) {
int h = 0;
Bitmap bitmap = null;
// 获取listView实际高度
for (int i = 0; i < listView.getChildCount(); i++) {

press(pressFormat.PNG, 100, out);
out.flush();
out.close();
}
} catch (IOException e) {
// TODO: handle exception
}
return bitmap;
}
4 截取线性布局或相对布局屏幕的方法
/**
* 截取RelativeLayout
**/
public static Bitmap getRelativeLayoutBitmap(RelativeLayout relativeLayout) {
int h = 0;
Bitmap bitmap;
for (int i = 0; i < relativeLayout.getChildCount(); i++) {
h += relativeLayout.getChildAt(i).getHeight();
}
// 创建对应大小的bitmap
bitmap = Bitmap.createBitmap(relativeLayout.getWidth(), h,
Bitmap.Config.ARGB_8888);
final Canvas canvas = new Canvas(bitmap);
relativeLayout.draw(canvas);
return bitmap;
}
/**
* 截取LinearLayout
**/
public static Bitmap getLinearLayoutBitmap(LinearLayout linearLayout) {
int h = 0;
Bitmap bitmap;
for (int i = 0; i < linearLayout.getChildCount(); i++) {
h += linearLayout.getChildAt(i).getHeight();
}
// 创建对应大小的bitmap
bitmap = Bitmap.createBitmap(linearLayout.getWidth(), h,
Bitmap.Config.ARGB_8888);
final Canvas canvas = new Canvas(bitmap);
linearLayout.draw(canvas);
return bitmap;
}
5 截取除了导航栏之外的整个屏幕
/**
* 截取除了导航栏之外的整个屏幕
*/
public static Bitmap screenShotWholeScreen(Activity activity) {
View dView = activity.getWindow().getDecorView();
dView.setDrawingCacheEnabled(true);
dView.buildDrawingCache();
Bitmap bitmap = Bitmap.createBitmap(dView.getDrawingCache());
return bitmap;
}
