Question

i want to learn how to create an android app, and i'm confused at :

1.first time launching my app will display viewpagers img_btn ice, img_btn jelly. and when img_buttons clicked will display which image chosen in profil.xml, is there any solution do it in 1 xml or i must create 2 xml for each button?

2.if user have choosed img_button, main_activity will change to profil.xml, so for the second time launch will show profil.xml. how can i do that?

main_activity.xml

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center"
android:background="#000000"
>
<TextView
    android:text="Choose char"
    android:textSize="25dp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textColor="#1e00ff"/>
<android.support.v4.view.ViewPager
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/main_ViewPager"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#000000"/>

page1.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:background="#000000"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Halaman 2"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:id="@+id/textView"
    android:layout_gravity="center_horizontal"
    android:textSize="54dp"
    android:textColor="#0aedff"/>
<ImageButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/imageButton"
    android:background="#00000000"
    android:src="@drawable/btn_info"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_gravity="center_vertical|center"/>

page1.java

import android.support.v4.app.*;
import android.view.*;
import android.os.*;

public class page1 extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,   Bundle savedInstanceState)
{
    View v=inflater.inflate(R.layout.halaman_1, container,false);
    return v;
}
}

page2.xml and page2.java same as page1 English isn’t my first language, so please excuse any mistakes.

can you show your xlm. and code. also what do you want your image on? on the viewpager? or some imageView? — kggoh, Mar 28 '17 at 07:38
You can pass image url to second activity which show your image after click button. `Intent intent = new Intent(this, Activity2.class); String imageUrl = "put your image url here"; intent.putExtra("url", imageUrl); startActivity(intent);` — reza.cse08, Mar 28 '17 at 07:48

I am not sure what Fragment you extended. import android.support.v4.app.Fragment; or import android.app.Fragment; The below example assume you use support.v4

public void replaceFragment(Fragment fragment, String title) {
        getSupportFragmentManager().beginTransaction()
                .replace(R.id.content_frame, fragment)
                .addToBackStack(title)
                .commit();
    }

    public void addFragment(Fragment fragment, String title) {
        getSupportFragmentManager().beginTransaction()
                .add(R.id.content_frame, fragment, title)
                .addToBackStack(title)
                .commit();
    }

you better has 2 xml (eg. page1.xml, page2.xml) and two classes extend Fragment, you may use the above function to first add a fragment, subsequently use replace when you open new fragments. Notice there is a R.id.content_frame in the functions given. That is from your main_activity.xlm, make a linear_layout name it content_frame, which will hold the open fragment. You then put a button on page1.xml, put an ImageView inside page2.xml, when the button on page1 has been clicked. use replaceFragment to open page2.xml

display image choosen in xml and change main_activity on second time launch
