Replace fragments in FrameLayout layout

Question

I have tried every tutorial on the first google page about android fragments, but I can\'t get anything to work.

So I have one navigation bar activity, MainAct

Answer 1

Accroding to your question,

This is FrameLayout

<FrameLayout
        android:id="@+id/main_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/view"
        android:layout_marginTop="@dimen/medium_margin"></FrameLayout>

Now , call displayview method onCreate() of your activity,

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

    //rest of your code here
    displayView(0); // fragment at 0 position
}

displayView method, which have three fragements

public void displayView(int position) {
        switch (position) {
            case 0:
                tvTitle.setText(getResources().getString(R.string.signin_tile));
                showFragment(new LoginFragment(), position);
                break;
            case 1:
                tvTitle.setText(getResources().getString(R.string.forgot_password_tile));
                showFragment(new ForgotPasswordFragment(), position);
                break;
            case 2:
                tvTitle.setText(getResources().getString(R.string.change_password_tile));
                showFragment(new ChangePasswordFragment(), position);
                break;

        }
    }

---

showFragment method called from displayView method,

public void showFragment(Fragment fragment, int position) {
        FragmentTransaction mTransactiont = getSupportFragmentManager().beginTransaction();

        mTransactiont.replace(R.id.main_container, fragment, fragment.getClass().getName());
        mTransactiont.commit();
    }

Answer 2

I solved it!

Apparently, I had to use android.support.v4.app.Fragment; instead of android.app.Fragment;. This is the code I got it to work with:

protected void setFragment(Fragment fragment) {
    android.support.v4.app.FragmentTransaction t = getSupportFragmentManager().beginTransaction();
    t.replace(R.id.fragment_container, fragment);
    t.commit();
}

And to set it (from the nav bar onNavigationItemSelected(), you do this:

setFragment(new RoosterFragment());

I hope this helps others out with the same frustrating problem.

Try this one. it is my newbie code easier to understand :)

FragmentTransaction transaction;

switch (id){
            case R.id.button_fragment_one:
                    transaction = getSupportFragmentManager().beginTransaction();
                    transaction.replace(R.id.frame_layout, new FragmentOne());
                    transaction.addToBackStack(null);
                    transaction.commit();
                break;
            case R.id.button_fragment_two:
                    transaction = getSupportFragmentManager().beginTransaction();
                    transaction.replace(R.id.frame_layout, new FragmentTwo());
                    transaction.commit();
                break;
            default:
                break;
}
