This app is supposed to display images in which the students can count up what the money is worth in total, and then input the value in a editText text box, which is then compared against a stored value. Unfortunately, when I try to switch activities past a certain point (there are 11 active activities, with three of them displaying images fine), the images start blurring and the coins are hard to distinguish from each other. I do not know whether this is a Java or XML error, however I have pasted the code below. The following is XML code.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

That's just one of the 7 screens that look blurry when they display the images. The following is the Java code for the same activity.
package com.example.ldsm3;
import android.os.Bundle;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import com.example.ldsm3.Problem5;
public class Problem4 extends Activity
{
private final int COIN3_SCREEN_ANSWER = 95;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_problem4);
Button submitButton = (Button)findViewById(R.id.submitButton);
submitButton.setOnClickListener(submitButtonListener);
}
public boolean onCreateOptionsMenu(Menu menu)
{
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
private OnClickListener submitButtonListener = new OnClickListener()
{
public void onClick(View arg0)
{
EditText editText = (EditText)findViewById(R.id.userAnswer);
int userAnswerValue = Integer.parseInt(editText.getText().toString());
// Build the Alert Dialog
android.app.AlertDialog.Builder alert = new AlertDialog.Builder(Problem4.this);
alert.setTitle("Answer");
alert.setCancelable(false);
if(userAnswerValue == COIN3_SCREEN_ANSWER)
{
alert.setMessage("Congratulations!!!");
}
else
{
alert.setMessage("Sorry, that's not right.");
}
alert.setPositiveButton("OK",new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog,int id)
{
Intent nextCoinScreenIntent = new Intent(Problem4.this, Problem5.class);
startActivity(nextCoinScreenIntent);
}
});
alert.show();
}
};
}
And this a screenshot when it is running on a Nexus 10:
Please let me know if any more information is needed.
