OnItemClickListener Navigation Drawer

Question

I am making an app from the example of Android Developers with the Navigation Drawer. I made the items but I don\'t know how I can open new Activity from each of items enlis

Answer 1

switch(position) {
    case 1:
        Intent a = new Intent(Book.this, SecondActivity.class);
        startActivity(a);
        break;
    case 2:
        Intent b = new Intent(Book.this, ThirdActivity.class);
        startActivity(b);
        break;
    default:
}

Answer 2

 private class DrawerItemClickListener implements ListView.OnItemClickListener
 {
 @Override
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) 
     {
         SelectItem(position);
     }
  }

Answer 3

Instead of using Activities just use a fragment and A fragment Manager to transition between them

Answer 4

Instead of your code:

private void selectItem(int position) {

    Fragment fragment = new GalaxyFragment();
    Bundle args = new Bundle();
    args.putInt(GalaxyFragment.ARG_Galaxy_NUMBER, position);
    fragment.setArguments(args);

    FragmentManager fragmentManager = getFragmentManager();
    fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();


    mDrawerList.setItemChecked(position, true);
    setTitle(mGalaxyTitles[position]);
    mDrawerLayout.closeDrawer(mDrawerList);
}

Use this code:

private void selectItem(int position) {
    switch(position) {
    case 1:
            Intent a = new Intent(MainActivity.this, Activity1.class);
            startActivity(a);
    break;
    case 2:
            Intent b = new Intent(MainActivity.this, Activity2.class);
           startActivity(b);
           break;
    default:
    }
}

And remove this part: (It is not necessary)

public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

switch(position) {
case 1:
        Intent a = new Intent(MainActivity.this, Page1.class);
        startActivity(a);
break;
case 2:
        Intent b = new Intent(MainActivity.this, Page2.class);
       startActivity(b);
       break;
default:
}
}

Answer 5

In manifest you write this code:

<activity
    android:name=".firstactivity"
    android:parentActivityName=".MainActivity">
    <meta-data
        android:name="android.support.PARENT_ACTIVITY"
        android:value=".MainActivity"/>
</activity>

In Main activity:

Intent i=new Intent(MainActivity.this,firstactivity.class);
startActivity(i);

Answer 6

Use Like that

 switch (position) {

            case 0:
                fragment = new Free();

                break;
            case 1:
               fragment  = new Manage();

                break;
            case 2:
              fragment = new Paid();

                break;
            case 3:
                fragment = new Categories();

                break;
            case 4:
             logout();

                break;
            default:
                break;
        }
