Displaying dynamic images based on an Int value (for showing player's score on main menu)
JF
Disclaimer: I’m extremely new to Java/Xml, so please bear with me. I’m using Replica Island source so if there’s an easier/newer way of doing this, please let me know.
Objective: Display a player’s score on the main menu screen using .PNG numbers instead of text. Why? Because my .PNG numbers are much more flashy/stylized than standard text.
Currently: I’m capturing and displaying the player’s score via an int variable that’s saved to and loaded from in SharedPreferences. I’m then displaying it TEXT via the following:
<TextView
android:id="@+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:paddingTop="10dp"
android:textSize="24sp"
android:textColor= "#FF0000"
android:background="#99000000"
/>
int mHighScoreCoin = prefs.getInt(PreferenceConstants.PREFERENCE_COINS_COLLECTED, 0);
TextView text = (TextView) findViewById(R.id.text);
text.setText("Current High Score: " + mHighScoreCoin);
This works fine, but I don’t want basic text on my main menu. During actual gameplay, I’m using the following method to convert my int score, into an array that calls my .PNG numbers (0-9) to display them in game:
public int intToDigitArray(int value, int[] digits) {
int characterCount = 1;
if (value >= 1000) {characterCount = 4;}
else if (value >= 100) {characterCount = 3;}
else if (value >= 10) {characterCount = 2;}
int remainingValue = value;int count = 0;
do {
int index = remainingValue != 0 ? remainingValue % 10 : 0;
remainingValue /= 10;
digits[characterCount - 1 - count] = index;
count++;
} while (remainingValue > 0 && count < digits.length);
if (count < digits.length) {digits[count] = -1;}
return characterCount;
}
Question: How can I display the high score in my XML/MainmenuActivity class, using the .PNG version of the numbers instead of the text I’m currently using?
The start of my feeble Attempt:
…
mdrawScore = findViewById(R.id.drawScore);
…
if(mdrawScore !=null){
HudSystem hud = new HudSystem();
int[] mCoinDigitsForMenu;
mCoinDigitsForMenu = new int[4];
hud.intToDigitArray(mHighScoreCoin, mCoinDigitsForMenu);
}
Note: This question may be unanswerable with the information provided. Again, I’m extremely new to Java and in over my head. For example, do I need to be pulling a ton more stuff from “HudSystem” to finish creating the array of images?
Any details or general thoughts would be much appreciated.
Thanks!

Is it the cleanest, most effective approach? HIGHLY unlikely (again, I have almost no idea wtf i'm doing, lol). Regardless, it works, :).
**XML**
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="70dp"
android:orientation="horizontal"
android:gravity="bottom|center_horizontal"
android:id="@+id/mainSectionMenu"
>
<ImageView
android:id="@+id/drawScore"
android:layout_width="70dp"
android:layout_height="70dp"
android:orientation="horizontal"
android:layout_gravity="center_horizontal"
android:paddingTop="5dp"
android:layout_marginRight="-9dp"
android:clickable="false" />
<ImageView
android:id="@+id/drawScore2"
android:layout_width="70dp"
android:layout_height="70dp"
android:orientation="horizontal"
android:layout_gravity="center_horizontal"
android:paddingTop="5dp"
android:layout_marginLeft="-9dp"
android:layout_marginRight="-9dp"
android:clickable="false" />
<ImageView
android:id="@+id/drawScore3"
android:layout_width="70dp"
android:layout_height="70dp"
android:orientation="horizontal"
android:layout_gravity="center_horizontal"
android:paddingTop="5dp"
android:layout_marginLeft="-9dp"
android:clickable="false" />
</LinearLayout>
**MainMenuActivity**
After pulling the players mHighScoreCoin from SharedPreferences (onCreate AND onResume), I run the following:
if(mHighScoreCoin >99){
int HundsDigit = mHighScoreCoin/100;
ImageView imageviewHunds = (ImageView)findViewById(R.id.drawScore);
int hunds = HundsDigit;
String.valueOf(hunds);
int resIdHunds = getResources().getIdentifier("ui_" + String.valueOf(hunds), "drawable", getPackageName());
imageviewHunds.setImageDrawable(getResources().getDrawable(resIdHunds));
int tensDigit = ((mHighScoreCoin / 10)%10);
ImageView imageviewTens = (ImageView)findViewById(R.id.drawScore2);
int tens = tensDigit;
String.valueOf(tens);
int resIdTens = getResources().getIdentifier("ui_" + String.valueOf(tens), "drawable", getPackageName());
imageviewTens.setImageDrawable(getResources().getDrawable(resIdTens));
int onesDigit = (mHighScoreCoin % 10);
ImageView imageviewOnes = (ImageView)findViewById(R.id.drawScore3);
int ones = onesDigit;
String.valueOf(ones);
int resIdOnes = getResources().getIdentifier("ui_" + String.valueOf(ones), "drawable", getPackageName());
imageviewOnes.setImageDrawable(getResources().getDrawable(resIdOnes));
}
else if(mHighScoreCoin > 9)
{
int tensDigit = mHighScoreCoin/10;
ImageView imageviewTens = (ImageView)findViewById(R.id.drawScore);
int tens = tensDigit;
String.valueOf(tens);
int resIdTens = getResources().getIdentifier("ui_" + String.valueOf(tens), "drawable", getPackageName());
imageviewTens.setImageDrawable(getResources().getDrawable(resIdTens));
int onesDigit = (mHighScoreCoin % 10);
ImageView imageviewOnes = (ImageView)findViewById(R.id.drawScore2);
int ones = onesDigit;
String.valueOf(ones);
int resIdOnes = getResources().getIdentifier("ui_" + String.valueOf(ones), "drawable", getPackageName());
imageviewOnes.setImageDrawable(getResources().getDrawable(resIdOnes));
}
else {
ImageView imageviewOnes = (ImageView)findViewById(R.id.drawScore2);
int ones = mHighScoreCoin;
String.valueOf(ones);
int resIdOnes = getResources().getIdentifier("ui_" + String.valueOf(ones), "drawable", getPackageName());
imageviewOnes.setImageDrawable(getResources().getDrawable(resIdOnes));
}
