Activity not called from intent in onActivityCreated

Question

I have button in my Tab1.java, by clicking the button, it will call another class say Custom.java, But i am facing error:

"Intent cannot be resolved to a type"

I searched a lot but did not find any helpful post regarding this. Please Help me !

Tab1.java

public class Tab1 extends Fragment
{
    ListView lv;
    int FIRST_OPTION = 1;
    int SECOND_OPTION = 2;

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onActivityCreated(savedInstanceState);
    Button b = (Button) getView().findViewById(R.id.button4);
    registerForContextMenu(b);

    Button bi = (Button) getView().findViewById(R.id.button5);
    registerForContextMenu(bi);

    Button setting = (Button) getView().findViewById(R.id.setting);
    setting.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            startActivity(new Intent(getActivity(), Custom.class));             
        }
    });

    b.setOnCreateContextMenuListener(new OnCreateContextMenuListener() {

        @Override
        public void onCreateContextMenu(ContextMenu menu, View v,
                ContextMenuInfo menuInfo) {
            // TODO Auto-generated method stub
            menu.add(0, FIRST_OPTION, 0, "Activate");

                }
    });
bi.setOnCreateContextMenuListener(new OnCreateContextMenuListener() {

        @Override
        public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
            // TODO Auto-generated method stub

            menu.add(0, SECOND_OPTION, 0, "Activate");
        }
    });

}

@Override
public boolean onContextItemSelected(MenuItem item) {

    int itemId = item.getItemId();
    if(itemId == FIRST_OPTION){
        //Normal_Mode nm = new Normal_Mode();
        //nm.activateNormal(getApplicationContext());
    Toast.makeText(this.getActivity(), "Normal Mode Activated", Toast.LENGTH_SHORT).show();

    return true;

    }
    else if(itemId == SECOND_OPTION){
        //Silent_Mode sm = new Silent_Mode();
        //sm.activateSilent(getApplicationContext());
        Toast.makeText(this.getActivity(), "Silent Mode Activated", Toast.LENGTH_SHORT).show();

Hye there, Kindly try this way.

setting.setOnClickListener(new OnClickListener() {

 @Override
 public void onClick(View arg0) {
   /startActivity(new Intent(getActivity(), Custom.class));   
    Intent intent = new Intent((Tab1)getActivity(), Custom.class);
    (Tab1)getActivity().startActivity(intent);    

    }
});

There's some quick tips that may solve the problem:

1) Did you make sure that yourt Custom activity is registered in the android manifest?

2) Don't call the startActivity directly in your fragment, use an interface to communicate with the activity that is holding your fragment and do the startActivity there, this way is more clean.

3) Don't use class names like Custom or Tab1 use CustomActivity and TabFragment, follow the android code style guidelines.

Code guidelines

Communication Fragment-Activity

Keep in mind that if some day, your boss or someone tells you "Well, now we're going to do a version for Tablet devices" this code is going to need a lot of changes, that's why you've to communicate your fragments with your activities, and perform the logic there.

Tell me if you have any problem, or if the issue doesn't get resolved.

Thanks for your time buddy. i have solved my problem. See above. For you, i will give +1 — zeeshan haider, Oct 17 '15 at 16:56
