直接上代码
截取整个activity
/**
* The activity passed in is the activity to be screenshot
*/
public static Bitmap getViewBitmap(Activity activity) {
View view = activity.getWindow().getDecorView();
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();
Bitmap b1 = view.getDrawingCache();
Rect frame = new Rect();
activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);
int statusBarHeight = frame.top;
int width = activity.getResources().getDisplayMetrics().widthPixels;
int height = activity.getResources().getDisplayMetrics().heightPixels;
Bitmap b = Bitmap.createBitmap(b1, 0, statusBarHeight, width, height - statusBarHeight);
view.destroyDrawingCache();
return b;
}
截取ViewGroup
public static Bitmap getViewBitmap(ViewGroup viewGroup) {
if(viewGroup.getBackground()==null){
viewGroup.setBackgroundColor(Color.WHITE);
}
//Total height of ViewGroup
int h = 0;
Bitmap bitmap;
// Apply to ListView or RecyclerView
for (int i = 0; i < viewGroup.getChildCount(); i++) {
h += viewGroup.getChildAt(i).getHeight();
}
bitmap = Bitmap.createBitmap(viewGroup.getWidth(), h, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
viewGroup.draw(canvas);
return bitmap;
}
注意：
截取的viewgroup 要设置背景色，截取ScrollView时子Linearlayout也要设置背景色
