The pendintent can be obtained in two ways. One is pendingintent. getactivity (); that is, jump to the corresponding activity to process your affair.
Pendingintent = pendingintent. getactivity (context,
0/* No requestcode */, intent, 0/* no flags */);
Views. setonclickpendingintent (R. Id. ivcover, pendingintent );
