my two fragments under the same activity are shown one above the other

Question

I have an activity:

public class MainActivity_with_Fragment extends RoboFragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main_activity2);
        if (savedInstanceState == null) {
            getSupportFragmentManager().beginTransaction()
                    .add(R.id.container, new SettingsFragment())
                    .add(R.id.container, new AddReminderFragment())
                    //.add(R.id.container, new ReadRemindersFragment())
                    .commit();
        }
    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main_activity2, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

with this layout:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
             xmlns:tools="http://schemas.android.com/tools"
             android:id="@+id/container"
             android:layout_width="match_parent"
             android:layout_height="match_parent"
             tools:context="com.example.stopcall.app.activities.dele_MainActivity2_with_Fragment"
             tools:ignore="MergeRootFrame"/>

I want it to host 3 fragments separately (showing only one every time):

Add Item to DB fragment

Read Items from the DB

Setting fragment

How would you suggest to design and implement this? what is the proper way?

You are adding both the fragments in same container. If you need to show only one at a time then user `replace` method not `add`. But if you need to show both at same time then add them in different containers. Please see my answer — Rohit5k2, Jan 31 '15 at 21:42

You are adding both the fragments in same container. If you need to show only one at a time do this.

getSupportFragmentManager().beginTransaction()
   .add(R.id.container, new SettingsFragment()).commit();

getSupportFragmentManager().beginTransaction(
   .replace(R.id.container, new AddReminderFragment()).commit();

But if you need to show both together then create a new container (say R.id.container_two) and do this

getSupportFragmentManager().beginTransaction()
     .add(R.id.container, new SettingsFragment()).commit();
getSupportFragmentManager().beginTransaction()
    .add(R.id.container_two, new AddReminderFragment()).commit();

and how will i move from one fragment to the second? with one container? – Elad Benda Jan 31 '15 at 21:47
ahh I see the replace. and other dynamic way to set all fragment and move between them? – Elad Benda Jan 31 '15 at 21:48
This depends what are you trying to do. Try this code and see if your problem is solved. – Rohit5k2 Jan 31 '15 at 21:50
I want to slide right and left between the fragments – Elad Benda Jan 31 '15 at 21:51

You need to use Fragment pager then. See this http://developer.android.com/reference/android/support/v4/app/FragmentPagerAdapter.html – Rohit5k2 Jan 31 '15 at 21:55
with your solution I can only alter to the first fragment again if I use "replace" one more time? – Elad Benda Jan 31 '15 at 22:13

If you need to slide your fragments to left/right then this is not the approach to do it (see my previous comment). My code gave you the solution of what you originally asked. – Rohit5k2 Jan 31 '15 at 22:14

my two fragments under the same activity are shown one above the other
