Answer 1

type cast it with activity.

((Activity)context).finish();

You cannot always assume that the context is Activity. It can also be ContextThemeWrapper. See https://mcmap.net/q/302768/-contextthemewrapper-cannot-be-cast-to-activity – Emphasize

Answer 2

Try with the following code:

public YourAdapterName(......,Context context){

...

this.myContext=context;
}

And in your adapter getView()

btn.setOnClickListener(new Button.OnClickListener() {

    @Override
    public void onClick(View v) {
        ((YourActivityName)myContext).yourDesiredMethod();

    }
});

For Kotlin code:

(context as Activity).finish()

Try passing your Activity as an activity parameter, then you'll be able to call finish() on it. Hope this helps.

Code for this is ((Activity)context).finish();and complete code is

holder.cardUsers.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Intent intent1=new Intent(mcontext,AstroChatPanel.class);
        intent1.putExtra("mobile",userslist.get(position).getMobile());
        intent1.putExtra("name",userslist.get(position).getName());
        intent1.putExtra("type","admin");
        mcontext.startActivity(intent1);

i have not used it but i hope it will work. use: "this.recreate()" if you are want to reload it from within the activity.

if you want to reload it from Adapter then use: "((Activity)context).recreate()"

Andry

Answer 9

Typecast your activity name with context and finish activity

Sanious

Answer 10

You shouldn't pass context object in your adapter classes.

You can use Kotlin Higher Order Function (https://kotlinlang.org/docs/lambdas.html#instantiating-a-function-type) in a variable in your adapter, then you can use it where you use the adapter in fragment or activity.

Than you can use your activity context where it called.

Example:

Adapter Class:

var onClick = () -> Unit

Fragment:

adapterInstance.onClick = {this.activity?.finish()}

Answer 12

close Activity form Class Custom Adapter just in method

 @Override
  public void onClick(View v) {
    MyApplication.value=mCompany.getCompanyId();
    Intent intent = new Intent(MyApplication.context, VaasetActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
   intent.putExtra("ID_COMPANY",mCompany.getCompanyId());
    MyApplication.context.startActivity(intent);
    ((Activity)context).finish();
  }
});
