从 recyclerview 适配器开始新活动

Question

I am reading data from firebase real time database to a recyclerview and on the recyclerview item there a button to start a new activity. I have this onClick method

public void bookBtnOnClick(final int position){
        mBookButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mContext.startActivity(new Intent(this,ReservationForm.class));
                }
        });
    } 

But it cannot resolve intent constructer

Answer 1

而不是这个尝试mContext因为我猜你是在 Adapter 类中尝试它

  mContext.startActivity(new Intent(mContext,ReservationForm.class));

Answer 2

将'this'改为'mContext' ；

mContext.startActivity(new Intent(mContext,ReservationForm.class));

Answer 3

try-->

Intent intent =  new Intent(context, ReservationForm.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
mcontext.startActivity(intent);

Answer 4

Adding more to @S.ambika's answer.

Change this to mContext when creating Intent .

mContext.startActivity(new Intent(mContext,ReservationForm.class));

As when you use this , it will give the current context. In your case this is returning the context of onClick and for starting a new Activity, we need the context of Activity .

Answer 5

try this:

public void bookBtnOnClick(final int position){
     mContext.startActivity(new Intent(context, ReservationForm.class));
} 

Answer 6

How's about this

Intent intent = new Intent (v.getContext(), ReservationForm.class);
v.getContext().startActivity(intent);

Answer 7

Define Context mContext;  on starting of adapter and in constructor use this.mcontext=mcontext;

mContext.startActivity(new Intent(mContext,ReservationForm.class));
