I will make this as specific as possible. I've created a Page Which uses RecyclerAdapter to show card items in grid.And I have set a Default Activity for each card using OnclickListner ,So when you click any card item it will take you to that Default Activity Like this Image.And mine one Look Like this click here.My question is how can I open a perticular card in recyler Adapter from a different activity.In my app I want that when I press Go button on popup It will it toggle lvl2 or the next card to open the game activity.

What I understand is you want to open different activities on each card click.If it's correct then,
use switch inside your onClick and open your activity on a particular item click
#Override
public void onClick(View v) {
final Intent intent;
switch (getAdapterPostion()){
case 0:
intent = new Intent(context, FirstActivity.class);
break;
case 1:
intent = new Intent(context, SecondActivity.class);
break;
...
default:
intent = new Intent(context, DefaultActivity.class);
break;
}
context.startActivity(intent);
}
Or Use:-
#Override
public void onClick(View v) {
final Intent intent;
if (getAdapterPosition() == sth){
intent = new Intent(context, OneActivity.class);
} else if (getPosition() == sth2){
intent = new Intent(context, SecondActivity.class);
} else {
intent = new Intent(context, DifferentActivity.class);
}
context.startActivity(intent);
}

Your fragment is loaded from MainActivity and not EditorActivity, hence the class cast exception. If you want to pre-fill some data in the editor activity, you can pass that in the intent ( the code you commented on your onclick listener) and retrieve in the EditorActivity and set your UI elements.
Edited
buttonExpense.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(fa2, EditorActivity.class);
intent.putExtra("result", result);
startActivity(intent);
}});
In your EditorActivity class, in on create
String result=getIntent().getStringExtra("result")
updateGoldTextView(result)
I have a button that goes from one activity to another activity and its supposed to save the value int Counter, but every time it never saves. What am I doing wrong? I have seen other solutions, but i check and im doing the exact same thing as them.

public class MainActivity extends AppCompatActivity {
private Button myButton;
private int Counter;
private Button myButton2;
private TextView myTextView;
Handler handler = new Handler();
private int add;
#Override
protected void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.activity_main);
super.onCreate(savedInstanceState);
if (savedInstanceState != null) {
add = savedInstanceState.getInt("Count");
Counter = savedInstanceState.getInt("Add");
}
myButton = (Button) findViewById(R.id.button);
myButton2 = (Button) findViewById(R.id.button2);
myTextView = (TextView) findViewById(R.id.textView);
myButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Counter = ButtonCounter(Counter);
}
});
myButton2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent(getApplicationContext(), SecondActivity.class);
intent.putExtra("Count", Counter);
startActivity(intent);
}
});
handler.postDelayed(new Runnable() {
#Override
public void run() {
Counter = AutoCounter(Counter, add);
Display(Counter, myTextView);
handler.postDelayed(this, 100);
}
}, 10);
}
protected void onSaveInstanceState(Bundle savedInstanceState) {
super.onSaveInstanceState(savedInstanceState);
savedInstanceState.putInt("Count", Counter);
savedInstanceState.putInt("Add", add);
}
public int ButtonCounter(int Counter) {
Counter += 1;
return Counter;
}
public int AutoCounter(int Counter, int add) {
Counter += add;
return Counter;
}
public void Display(int Counter, TextView myTextView) {
String man = String.valueOf(Counter);
myTextView.setText("$" + man);
}
}
you're not implementing the right method
from the docs:
#Override
public void onSaveInstanceState(Bundle savedInstanceState) {
savedInstanceState.putInt("Count", Counter);
savedInstanceState.putInt("Add", add);
// call superclass to save any view hierarchy
super.onSaveInstanceState(outState);
}

I am working on this small game where each 500 ms an image is set to the image view
so what i want to check is when i click one of the arrow images(left,right,up,down) to check if it is equal to the random image ...if so then the score increases by 1.
here is my layout
https://i.stack.imgur.com/wPxZB.png

import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;

import android.widget.TextView;
import android.widget.Toast;
import java.util.Timer;
import java.util.TimerTask;
public class GameActivity extends AppCompatActivity {

#Override

mTimer.schedule(new TimerTask() {
#Override

runOnUiThread(new Runnable() {
#Override

}
});
}

img_up.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(pos==2){
SCORE++;
score.setText(SCORE+"");
}
}
});
img_down.setOnClickListener(new View.OnClickListener() {
#Override

You are checking the data in the index and you need the position so use this instead:
pos = Array.asList(arrayBuckets).indexOf((int) (Math.random() * arrBuckets.length));
img_up.setOnClickListener(new View.OnClickListener() {
#Override public void onClick(View view) {
if(pos==2)
{
SCORE++;
score.setText(SCORE+"");
}
});
I have an app where I would like to be able to click on a button, A, and show a certain set of information. Then click the back button and click on button B and show a different set of information. I have coded a test TextView into the Drinks.java file in order to begin the process by confirming what is being passed along. Currently whatever button I push first is getting stuck in the variable. So for example if I push button A, then push the back arrow and push button B, button A is still showing up in the textView. I tried making the Strings empty within the on click listener, to "clear them out" as it were, but that isn't working. Is there a way to wipe out what is in the variable and reassign something else? Or does my problem lie elsewhere?

Please, use instead for instance the intent sent to the launching Activity:
How do I get extra data from intent on Android?
I have created a soundboard and everytime i click on a button to play a certain sound nothing happens. Here is the sound manager code:
package com.androidbook.ufgsoundboard;
import java.util.HashMap;
import android.app.Activity;
import android.content.Context;
import android.media.AudioManager;
import android.media.SoundPool;
public class SoundManager extends Activity {
private SoundPool mSoundPool;
private HashMap<Integer, Integer> mSoundPoolMap;
private AudioManager mAudioManager;
private Context mContext;
public SoundManager()
{
}
public void initSounds(Context theContext) {
mContext = theContext;
mSoundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 0);
mSoundPoolMap = new HashMap<Integer, Integer>();
mAudioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);
}
public void addSound(int Index,int SoundID)
{
mSoundPoolMap.put(Index, mSoundPool.load(mContext, SoundID, 1));
}
public void playSound(int index) {
int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, 0, 1f);
}
}
And here is the soundboard code:

}};
I cant work out why it wont load. The button highlights when pressed but no sound. Am I missing something obvious?
Thanks
Your code is so complicated ,Use this instead it worked for me !!
This is an example for a single button that plays sound
package com.example.soundtest;
import android.app.Activity;
import android.media.SoundPool;
import android.media.AudioManager;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class MainActivity extends Activity {
/** Called when the activity is first created. */
Button white;
SoundPool spool;
int soundID;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.setVolumeControlStream(AudioManager.STREAM_MUSIC);
spool = new SoundPool(1, AudioManager.STREAM_MUSIC, 0);
soundID = spool.load(this, R.raw.anysoundfile, 1);
white = (Button)findViewById(R.id.button1);
white.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Sound();
}
});
}
public void Sound(){
AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
float volume = (float) audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
spool.play(soundID, volume, volume, 1, 0, 1f);
};
}
