I labeled in my code where I want to intent to start, yet I keep getting the error: "Cannot resolve constructor Intetn(.....)"
The code I tried was this:
Intent i = new Intent(this, WhichGameActivity.class);
Thanks for any help :)
Cheers.
Use this:
new Intent(GFX.this,WhichGameActivity.class);
You can't just use this because you're inside a inner class, thus this belongs to the inner class context.
Pay attention to what Docs say about Intent constructor:
public Intent (Context packageContext, Class cls)
Create an intent for a specific component. ...
Parameters
packageContext A Context of the application package implementing this
class. cls The component class that is to be used for the
intent.
Your class MyBringBack is not a Context,so you can not use this code:
Intent i = new Intent(this, WhichGameActivity.class);
You have to store context that is received in constructor of MyBringBack as a field for example "myContext" and then use it in new Intent() like this:
Intent i = new Intent(myContext, WhichGameActivity.class);

With help of some question i managed to add volume and brightness control to my video player with onTouchEvent method. But when i swipe up or down my app close(it Restarts). Any help on my code why am not able to control volume and brightness using onTouchEvent.

FYI: i can't make Log since i don't have emulator. your help would be more helpful thanks in advance.
Edit: when i swipe down on volume it move to zero, it doesn't reduce slowly and only the volume down works.

to control brightness and volume by touch i managed to find https://github.com/moneytoo/Player which let me to do the function with more feature and uses the exoplayer library
and easy to build as same as exoplayer.
I have a piece of code that compares to images and places a marker on the difference. So far it works well, except the latest marker layer that is added always shows underneath all the older markers. I have the latest one as a yellow color and the older ones as red. When the difference is close to one of the red markers, the yellow marker shows behind those ones.
Is there anyone that can help me get the yellow (Latest marker) to appear on top?

You can give the z-order of the child view with addView() function.
void addView (View child, int index)
ex)
private void addImageToImageview(){
if (ViewcontrollerActivity.workSession.workScreenShot != null) {
imageViewtest.setImageBitmap(ViewcontrollerActivity.workSession.workScreenShot);
Log.d("width", String.valueOf(imageViewtest.getWidth()));
}
Resources r = getResources();
float px = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 20, r.getDisplayMetrics());
int currChildrenCount = relativeLayout_work.getChildCount();
for (int i = 0; i < ViewcontrollerActivity.workSession.getShotCount(); i++) {
PointF p = ViewcontrollerActivity.workSession.getPoint(i);
TextView t = new TextView(this);
t.setText("" + (i + 1));
RelativeLayout.LayoutParams param = new RelativeLayout.LayoutParams((int)px, (int)px);
relativeLayout_work.addView(t, currChildrenCount+i); // You can control the order like this
t.setLayoutParams(param);
t.setGravity(Gravity.CENTER);
t.setBackgroundResource(R.drawable.circle);
p = Session.convertPointBitmap2View(p, relativeLayout_work, ViewcontrollerActivity.workSession.workScreenShot);
t.setX(p.x);
t.setY(p.y);
t.setTag(10000 + i);

Hi I am having a problem accessing variables/methods in my view class from my main activity. I just need to return the turns int from GameView.java and be able to access it in MainActivity and then insert it into my database. I try to use GameView mGameView = new GameView(getApplicationContext()); but this doesn't work and I can't access any methods from GameView with this.
My GameView class:
public class GameView extends View {
int mcolumns = 5;
int mrows = 5;
private NetwalkGrid mGame = new NetwalkGrid(mcolumns, mrows);
private GestureDetector mGestureDetector;
Random rand = new Random();
int sizeSqX;
int sizeSqY;
int sizeSq;
int turns = 0;
Paint bgPaint;
public GameView(Context context) {
super(context);
init();
}
private void init() {
bgPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
bgPaint.setStyle(Paint.Style.FILL);
bgPaint.setColor(0xff0000ff);
mGame.gridCopy();
for (int col = 0; col < mGame.getColumns(); col++) {
for (int row = 0; row < mGame.getRows(); row++) {
int num = rand.nextInt(3) + 1;
for (int turns = 1; turns < num; turns++) {
mGame.rotateRight(col, row);
}
}
}
}
#Override
protected void onDraw(Canvas canvas) {
canvas.drawColor(Color.BLACK);
sizeSqX = getWidth() / mcolumns;
sizeSqY = getHeight() / mrows;
if (sizeSqX < sizeSqY) {
sizeSq = sizeSqX;
}
else {
sizeSq = sizeSqY;
}
Bitmap b = BitmapFactory.decodeResource(getResources(), R.drawable.placeholder);
int cellContent;
int square = 140;
for (int col = 0; col < mGame.getColumns(); col++) {
for (int row = 0; row < mGame.getRows(); row++) {
cellContent = mGame.getGridElem(col,row);
if (cellContent == 1) {
b = BitmapFactory.decodeResource(getResources(), R.drawable.up_down); // Image for down position
if (cellContent == 65 && mGame.checkWin()) {
b = BitmapFactory.decodeResource(getResources(), R.drawable.up_down_connected);
}
}
else if (cellContent == 2) {
b = BitmapFactory.decodeResource(getResources(), R.drawable.left_right); // Right position
if (mGame.checkWin()) {
b = BitmapFactory.decodeResource(getResources(), R.drawable.left_right_connected);
}
}
else if (cellContent == 3) {
b = BitmapFactory.decodeResource(getResources(), R.drawable.right_down); // Down right position WORKS
if (mGame.checkWin()) {
b = BitmapFactory.decodeResource(getResources(), R.drawable.right_down_connected);
}
}
else {
b = BitmapFactory.decodeResource(getResources(), R.drawable.placeholder2); //
}
canvas.drawBitmap(b, null,new Rect(col * sizeSq, row * sizeSq,col*sizeSq+sizeSq, row*sizeSq+sizeSq), null);
TextPaint tp = new TextPaint();
tp.setColor(Color.GREEN);
tp.setTextSize(70);
tp.setTypeface(Typeface.create("Courier", Typeface.BOLD));
canvas.drawText("Moves: " + String.valueOf(turns), 10, 1180, tp);
}
}
}
#Override
public boolean onTouchEvent(MotionEvent event) {
int x = (int) event.getX();
int y = (int) event.getY();
int column = getColTouched(event.getX());
int row = getRowTouched(event.getY());
try {
mGame.rotateRight(column, row);
System.out.println(mcolumns);
mGame.checkWin();
if (mGame.checkWin()) {
System.out.println("check win works");
invalidate();
}
invalidate();
}
catch (ArrayIndexOutOfBoundsException err) {
System.out.println("User has pressed outside game grid - exception caught");
}

return super.onTouchEvent(event);

public int getColTouched(float x) {
return (int) (x / sizeSq);
}
public int getRowTouched(float y) {
return (int) (y / sizeSq);
}
public int getTurns() {
return turns;
}
}
MainActivity:
public class MainActivity extends AppCompatActivity {
private int mcolumns;
private int mrows;
DatabaseHelper myDb;
String test = "test data";
int turns;
static Context appcon;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
appcon = this;
myDb = new DatabaseHelper(this);
}
public void runGame(View view){
Intent intent = new Intent(this, GameViewActivity.class);
startActivity(intent);
}
public void runInstructions(View view) {
Intent intent = new Intent(this, InstructionsActivity.class);
startActivity(intent);
}
public void setTurns() {
GameView mGameView = new GameView(getApplicationContext());
this.turns = mGameView.turns;
System.out.println("Turns: " + Integer.toString(turns));
}
public void AddData() {
boolean isInserted = myDb.insertData(Integer.toString(turns));
if(isInserted == true) {
System.out.println("Data inserted");
}
else {
System.out.println("Data NOT inserted");
}
}
}
In MainAcivity, inside setTurns()
Replace this
this.turns = mGameView.turns; //you can't access this variable directly
with
this.turns = mGameView.getTurns(); // Calling the public method getTurns()
please see this answer for explanation about Access modifiers in Java
There are two ways to fix this.
1. Preferred way:
Add a new Method in GameView class
public int getTurns() {
return turns;
}
And use this method where you want to access turns like:
this.turns = mGameView.getTurns();
2. Bad way:
Make turns variable public.
i have downloaded a android game program from internet and i tried to run it gives error on Method and goto statement.
i know goto statement is not support in java..
i dont know they are any other tool or language .
i want to know which technology or tool or language they are used.

What you have here is not real Java, and you should not be using it as an example to learn Java programming from.
So what actually is this stuff?
It looks to me like someone has attempted to decompile an Android app, and the decompiler was unable to turn some of the code back into real Java. Instead, the decompiler has inserted goto "statements" in an attempt to convey the meaning of the code to the (human) reader.
This is obviously the output of a decompilation. While this is a good way to gain specific insight into programs, it's not beginner-level material just like #Jägermeister said, because jads lack the clarity and brevity of standard Java source code.
For example, the goto keyword is not supported on the source code side of the JDK, but it is used inside the byte code in the form of jump instructions. Breaks, continues, loops, ifs etc. may be turned into jumps in surjective ways. The decompiler cannot restore the original construct and resorts to just putting the gotos and labels in the jad. It's up to the programmer to restore reasonable, compilable flow constructs.
That said, the comprehensive answer to your question would be: it's java, but rather an image of the byte code stuff, not a strict restoration of the source code, and requires a manual touch-up to be compilable again.
How to animate Cards in android Card Game Like "Spades Free". My game is quite the same as crazy 8.i used android game development for dummies as a reference.but, i want to animate cards how can i do that.
