把TextView轉(zhuǎn)換成Bitmap報(bào)空指針異常
TextView?tv?=?(TextView)?mWaitting.findViewById(R.id.id_age_and_gender);
tv.setText(age+"");
Log.d("TAG","here");
if(isMale){
????tv.setCompoundDrawablesWithIntrinsicBounds(getResources().getDrawable(R.drawable.male),null,null,null);
}else?{
????tv.setCompoundDrawablesWithIntrinsicBounds(getResources().getDrawable(R.drawable.female),null,null,null);
}
tv.setDrawingCacheEnabled(true);
Bitmap?bitmap?=?Bitmap.createBitmap(tv.getDrawingCache());
tv.destroyDrawingCache();
return?bitmap;Bitmap bitmap = Bitmap.createBitmap(tv.getDrawingCache());這個(gè)位置報(bào)空指針異常，怎么辦

是自己在解析的時(shí)候沒有用把mWaitting設(shè)置為可見，問題已經(jīng)解決了
