Make an array of the images then add that to your image switcher. You would also need to add some type of current index constant variable so you can index the switching

I am making a simple app in which context view changes and then a toast message is displayed as input given by user. I don't understand why the app keeps on crashing when changing the context view.
Also Android studio gives this warning:
Method "Toaster" is missing in "FirstActivity" or has incorrect signature.
Here is my code:

MainScreen.java:
package com.example.nautatvanavlakha.abcd;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.Toast;
public class MainScreen extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_screen);
}
public void toaster(View view){
EditText toast = (EditText)findViewById(R.id.toastText);
String final_toast = toast.getText().toString();
Toast.makeText(getApplicationContext(), final_toast, Toast.LENGTH_SHORT).show();
}
}
EDIT: As suggested, I moved the toaser function to FirstActivity.Java and deleted the MainScreen.java file as it becomes pointless to keep it. But the major problem is when I press the button (id named) the app keeps stopping.
EDIT2: I found that setContentView(R.layout.activity_main_screen) in FirstActivity.Java needs to be above this code
TextView textView = (TextView) findViewById(R.id.welcome);
textView.setText("Hi " + owner_string + ".");
Log.d(TAG,"owner name is set");
so that Activity has access to all the layout components. Thanks solved :)
You replaced the content view in the first activity with a layout that include the onClick attribute, but you have no public void toaster(View view) method there.
So, either don't use setContentView a second time, or implement that method on both Activities.
The recommended way to replace the view is Fragments, by the way
This is a wrong way to change the contents of your Activity, The main problem here is that you have onClick attribute set to "toaster", And you don't have a function called "toaster" in your FirstActivity.
Beside that, The MainScreen Activity in your code will never be used.
So, Your problem is that you set the FirstActivity contents to "activity_main_screen.xml", And FirstActivity doesn't have "toaster" method in it, When you change the context, the Activity will try to find toaster method and the app will crash because the method doesn't exist in FirstActivity.
You can solve this problem by making a method called "toaster" inside FirstActivity, But
This is a very bad practice, You can use Fragments instead, Or you can use Intent to move to another activity.
Some useful links about Fragments:

Why should I use fragment in Android?
I am trying to make a simple Planner app so I have an XML file with a ListView on it, and another XML file with an EditText and a sumbit button on it, and of course my Java files. I have done a ton of research but I can't find a working method to make it when I press the button, it adds the EditText stuff to the ListView as an item. Here is my code:

Please help, thank you.
Take a look on this google developers project. It's for animations but i think it also have the solution to your question.
https://developer.android.com/training/animation/layout.html
You should append data to the collection of items linked to your ListView via your adapter and notify your adapter that your data has changed. This illustration assumes that you have a List of String objects.
EditText editText = ...
List<String> list = ...
YourAdapter adapter = ...
ListView listView = ...
You must have done something like this to setup your listView.
listView.setAdapter(new YourAdapter(list, this));
Now on button click you should get the String in EditText, add it to your List and finally notify the adapter that your data has changed in order to update your ListView for e.g.
void OnButtonClick(View view){
String strToAdd = editText.getText().toString();
list.add(strToAdd);
adapter.notifyDataSetChanged();
}
So I have an ImageView in my xml file that is an image I created. The id of it is gameplayTop. In my java file for that activity, I try to set a variable to set that imageview, but then when I start up my emulator it says "Error: cannot find symbol variable gameTop".
Here is my xml file:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.ics466.brainscrew.GameplayActivity"
android:background="#color/background">
<Chronometer
android:layout_width="100dp"
android:layout_height="wrap_content"
android:id="#+id/chronometer"
android:layout_centerHorizontal="true" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/gameplay_Area"
android:src="#drawable/playarea"
android:layout_alignParentTop="true"
android:layout_alignParentEnd="true" />
<ImageView
android:layout_width="100dp"
android:layout_height="250dp"
android:id="#+id/gameLeft"
android:src="#drawable/gameplay_left_blue"
android:layout_alignParentStart="true"
android:layout_centerVertical="true" />
<ImageView
android:layout_width="250dp"
android:layout_height="100dp"
android:id="#+id/gameTop"
android:src="#drawable/gameplay_top_blue"
android:maxWidth="250dp"
android:maxHeight="95dp"
android:layout_marginTop="120dp"
android:layout_below="#+id/chronometer"
android:layout_centerHorizontal="true"
android:layout_gravity="right" />
</RelativeLayout>
And here is my javacode (with stuff cut out, but mainly I'm concerned with my imageview)
import android.media.Image;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
public class GameplayActivity extends AppCompatActivity {
ImageView top, bot, left, right;
String message;
private android.widget.RelativeLayout.LayoutParams layoutParams;
/**
* Sets the screen layout and sets this screen to fullscreen-mode.
*
* #param savedInstanceState saved previous state.
*/
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_gameplay);
top = (ImageView) findViewById(R.id.gameTop);
Random rnd = new Random(2);
int colorIndex = rnd.nextInt(8);
makeBorders(rand4());
}
Do I need to do something else to have it recognize the id?
Check your Xml files, and make sure they are properly closed />
I am trying to load a frame on the Onclicklistener of a Button in the main activity. In my view I have written all the code correctly of main activity and fragment that requires to attach a fragment to activity. But something seems off. Appreciate any thoughts or suggestions.

The error is in the main XML file.
You root is
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
But then the first child have the height fill_parent this makes the first child take all the space of the LinearLayout so when you try to put your fragment in the container, it wont appear in the screen.
Instead try this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
....
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent" >
Try to get used to use match_parent instead of fill_parent :)

Here, the common_status_bar.xml is a common layout. I have added this layout to game_activity.xml by <include layout="#layout/common_status_bar"/>.
It displays everything fine, no issue. But the case is I can't make any of it's elements to work. I have attached a OnClickListener to the first element of it, the goToLanguageSelection but it is not responding to the Click. I tested this by adding the click event to all other buttons, images as well (one at a time) and I got the same result. It is not responding to user click, or whatever.
Why this button and images in separate layout do not respond to the user events?
The commonView should not be created again.
If you want keep a reference of the common_status_bar.xml, you can give name it by an id, like the code below:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="10dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:paddingTop="10dp" >
<include
android:id="#+id/common_status_bar"
layout="#layout/common_status_bar" />
</RelativeLayout>
Then, change this code:
commonView = layoutInflater.inflate(R.layout.common_status_bar, null);
to:
commonView = findViewById(R.id.common_status_bar);
