Open a actvity when a if statement comes true

Open a actvity when a if statement comes true - android

Hi I want to open a activity when a if statement comes true. like "if gameStatus are equal to 12, then open scoreActivity". The Code:
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.GridLayout;
import java.util.Random;
import android.os.Build;
import android.os.Handler;
public class Game6x4Activity extends AppCompatActivity implements View.OnClickListener {
private int numberOfElements;
private int[] buttonGraphicLocations;
private MemoryButton selectedButton1;
private MemoryButton selectedButton2;
private boolean isBusy = false;
public int gameStatus;
public int gameScore;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.first_mode);
gameScore = 0;
gameStatus = 0;
GridLayout gridLayout = (GridLayout)findViewById(R.id.grid_layout_6x4);
int numColumns = gridLayout.getColumnCount();
int numRow = gridLayout.getRowCount();
numberOfElements = numColumns * numRow;
MemoryButton[] buttons = new MemoryButton[numberOfElements];
int[] buttonGraphics = new int[numberOfElements / 2];
buttonGraphics[0] = R.drawable.card1;
buttonGraphics[1] = R.drawable.card2;
buttonGraphics[2] = R.drawable.card3;
buttonGraphics[3] = R.drawable.card4;
buttonGraphics[4] = R.drawable.card5;
buttonGraphics[5] = R.drawable.card6;
buttonGraphics[6] = R.drawable.card7;
buttonGraphics[7] = R.drawable.card8;
buttonGraphics[8] = R.drawable.card9;
buttonGraphics[9] = R.drawable.card10;
buttonGraphics[10] = R.drawable.card11;
buttonGraphics[11] = R.drawable.card12;
buttonGraphicLocations = new int[numberOfElements];
shuffleButtonGraphics();
for(int r=0; r < numRow; r++)
{
for(int c=0; c <numColumns; c++)
{
MemoryButton tempButton = new MemoryButton(this, r, c, buttonGraphics[buttonGraphicLocations[r * numColumns + c]]);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
tempButton.setId(View.generateViewId());
}
tempButton.setOnClickListener(this);
buttons[r * numColumns + c] = tempButton;
gridLayout.addView(tempButton);
}
}
}
protected void shuffleButtonGraphics(){
Random rand = new Random();
for (int i=0; i < numberOfElements; i++)
{
buttonGraphicLocations[i] = i % (numberOfElements / 2);
}
for (int i=0; i < numberOfElements; i++)
{
int temp = buttonGraphicLocations[i];
int swapIndex = rand.nextInt(16);
buttonGraphicLocations[i] = buttonGraphicLocations[swapIndex];
buttonGraphicLocations[swapIndex] = temp;
}
}
private int buttonGraphicLocations(int i) {
return 0;
}
#Override
public void onClick(View view) {
if(isBusy) {
return;
}
MemoryButton button = (MemoryButton) view;
if(button.isMatched) {
return;
}
if(selectedButton1 == null)
{
selectedButton1 = button;
selectedButton1.flip();
return;
}
if(selectedButton1.getId()== button.getId())
{
return;
}
if (selectedButton1.getFrontDrawableId()== button.getFrontDrawableId())
{
button.flip();
button.setMatched(true);
if (selectedButton1 != null) {
selectedButton1.setEnabled(false);
System.out.println("not null");
}
else{
System.out.println("null");
}
if (selectedButton2 != null) {
selectedButton2.setEnabled(false);
System.out.println("not null");
}
else{
System.out.println("null");
}
gameStatus = gameStatus + 1;
gameScore = gameScore + 10;
if (gameStatus == 12){
Intent it = new Intent(Game6x4Activity.this, ActivityScore.class);
startActivity(it);
}
selectedButton1 = null;
return;
}
else
{
selectedButton2 = button;
selectedButton2.flip();
isBusy = true;
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run(){
selectedButton2.flip();
selectedButton1.flip();
selectedButton1 = null;
selectedButton2 = null;
isBusy = false;
}
},500);
return;
}
}
}
The activity that i want to open will show to the player his score. the activity is equal to all game modes, there will be some test to the app understant what path should go on. test like this one:
"
if (gameStatus == 12) {
gameScore = gameScore*55;
TextView scoreText = (TextView) findViewById(R.id.textView8);
scoreText.setText(gameScore);
}
else if (gameStatus == 15){
"
There are 4 game modes: This is the 6x4 game, where we can find 24 cards (12 images).

else if (gameStatus == 15){
Intent intent = new Intent(Game6x4Activity.this, NextActivity.class);
startActivity(intent);
}
I think, you are asking for this. You can pass value to another activity with
intent.putExtra("key",desired value);

ATTEMPT #3
This is the code that i've tried but I keep getting the same result (read comment below what I have done:
FrameLayout view = (FrameLayout)findViewById(R.id.contentLayout);
view.setDrawingCacheEnabled(true);
view.buildDrawingCache();
Bitmap bitmap = view.getDrawingCache();

I believe the image you are trying to save is getting removed during the onSwipe due to the library code. I think you need to move your code to before the onLike is called.
You're also attempting to get a bitmap from the cache of the entire layout, rather than the wanted ImageView here:
bm=contentLayout.getDrawingCache();
You'll want to get your current card view as a View, then, from my understanding of your code, the ID of your actual ImageView containing the expected bitmap is R.id.imgMeals, so I the suggest replacing the line:
bm=contentLayout.getDrawingCache();
with the following:
ImageView imageView = (ImageView) cardView.findViewById(R.id.imgMeals);
BitmapDrawable drawable = (BitmapDrawable) imageView.getDrawable();
Bitmap bm = drawable.getBitmap();
Move all of the below code from where you have it, to where I have marked //HERE!! in the following part of your code (or better, move it to a new method and call the method here).
// If the imageview of like is clicked
case R.id.imgLike: {
// HERE!!
// The imageview in the contentlayout will be swiped to the right
mSwipeView.likeCard();
break;
}
This is the code to me moved including the change I mention above:
View cardView = mSwipeView.getChildAt(mSwipeView.getChildCount() - 1);
ImageView imageView = (ImageView) cardView.findViewById(R.id.imgMeals);
BitmapDrawable drawable = (BitmapDrawable) imageView.getDrawable();
Bitmap bm = drawable.getBitmap();
OutputStream fOut = null;
try {
// Save on my sd card
File root = new File(Environment.getExternalStorageDirectory()
// Making a folder name Food Inspiration
+ File.separator + "Food Inspiration" + File.separator);
root.mkdirs();
File sdImageMainDirectory = null;
// Loop for having a different name for every image
int i = 0;
do {
sdImageMainDirectory = new File(root, "pic-" + i + ".png");
i++;
} while (sdImageMainDirectory.exists());
fOut = new FileOutputStream(sdImageMainDirectory);
// Updates the gallery of your phone with the folder and the "liked" images in it
MediaScannerConnection.scanFile(this, new String[] { sdImageMainDirectory.getAbsolutePath() }, null, null);
// If something goes wrong
} catch (Exception e) {
Toast.makeText(this, "Error occured. Please try again later.",
Toast.LENGTH_SHORT).show();
}
// Compresses the actual bitmap image
try {
bm.compress(Bitmap.CompressFormat.PNG, 100, fOut);
fOut.flush();
fOut.close();
} catch (Exception e){}

How to randomize images in the buttons in android

I am developing a game program where I want to store images in the buttons. I want to randomize the images shown in the buttons when the users play the game again, but I don't know how to randomize the images.
public class MainActivity extends Activity {
public static final String COME_FROM = "come_from";
private int[] id_mc = new int[16];

You had the Collections.shuffle() part right, you just need to get the randomized list back into your array:
private Integer[][] img_mc = new Integer [16][2];
...
List<Integer[]> img_mc_list = new ArrayList<Integer[]>();
for (Integer[] img : img_mc) {
img_mc_list.add(img);
}
Collections.shuffle(img_mc_list);
img_mc_list.toArray(img_mc);
Or use this:
private void randomize(Integer[][] array) {
int index;
Integer[] temp;
Random random = new Random();
for (int i = array.length - 1; i > 0; i--) {
index = random.nextInt(i + 1);
temp = array[index];
array[index] = array[i];
array[i] = temp;
}
}

Android - Imageviews make them visible again, dont work

I have a problem with my ImageViews.
At a certain time I disable it and make it invisible. Later in the program, but they should be re-enabled and visible. Unfortunately it does not work. I have often tried to find the bug with the debugger, but the corresponding code is not skipped. Nevertheless, the buttons in the app are not visible or enabled. Even the animated drawable does not start, even though it should. This should happen when calling from playanimation().
As this is my first app or program, the code is a bit unreadable.
Maybe can help me?
Here's the code:
I mean that part of the code:
case 1:
imageViewsleepbutton.setVisibility(View.VISIBLE);
imageViewfeedbutton.setVisibility(View.VISIBLE);

Unable to receive values more than 255 on Android device from Arduino

I am developing an application to receive data on an Android device from an Arduino. It displays values only up to 255 when I convert it to integer, but I want those values which are sent by the Arduino board. I have tried converting them to strings but that didn't work either.
How can I solve this problem?

It looks like the problem is in the Arduino sketch. The msg array contains (unsigned) bytes which have a maximum value of 255.
The line:
msg[1] = value/10
implicitly truncates value/10 (which is an integer between 0 and 1023 - see http://arduino.cc/en/Reference/analogRead) to a maximum of 255.
To send value/10 you'll need to split it over 2 bytes. For example:
msg[1] = (uint8_t) (i & 0xFF);
msg[2] = (uint8_t) ((i >> 8) & 0xFF);
And msg will have to be one byte longer to accomodate.
On the Android (Java) side you'll need to do something like:
int value = (int) buffer[0];
// ...
int tds = buffer[1] + (buffer[2] << 8);
m.obj = new ValueMsg('f', value, ret, tds,
buffer[3], buffer[4], buffer[5], buffer[6]);
which will require a change to the definition of ValueMsg to accomodate.
Also, there may be a problem with the calls to SndData (assuming the library being used here is the USB_Host_Shield_2.0) as they always send 6 bytes even though in the first time through loop all 6 bytes of msg won't have been initialized.

See this link this will help you to solve your problem.
I am using this code in my project for playing audio files. I am not using mediaPlayer.prepair();
see if this help's you...
bGSound = MediaPlayer.create(MusicPlay.this,R.drawable.music_ground);
float bGLeftVol = (float) (bGSoundVolume.getProgress()/100.0);
float bGRightVol = (float) (bGSoundVolume.getProgress()/100.0);
bGSound.setLooping(true);
bGSound.setVolume(bGLeftVol, bGRightVol);
bGSound.start();

The Android operating system is a mobile operating system that was developed by Google (GOOGL?) to be primarily used for touchscreen devices, cell phones, and tablets.

Open a actvity when a if statement comes true - android

else if (gameStatus == 15){ Intent intent = new Intent(Game6x4Activity.this, NextActivity.class); startActivity(intent); } I think, you are asking for this. You can pass value to another activity with intent.putExtra("key",desired value);
