Calling a local variable in a class from another class

Calling a local variable in a class from another class - java

im having a trouble while i call acce variable of this class
public class Slider extends AppCompatActivity {
...
public double[] acce={3.00,2.00,1.00};
public double[] gyro={3.00,2.00,1.00};
#Override
protected void onCreate(Bundle savedInstanceState) {
...
accelerometer = new Accelerometer(this);
gyroscope = new Gyroscope(this);
accelerometer.setListner(new Accelerometer.Listner() {
#Override
public double[] onTranslation(float ax, float ay, float az) {
acce = setAccValue(ax,ay,az);
return acce;
}
...
}
from this class
public void AntremanSayfasi(Context context){
...
Slider slider = new Slider();
AntremanaBasla.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
aa = (float) slider.acce[0];
bb = (float) slider.acce[1];
cc = (float) slider.acce[2];
accx.setText(String.valueOf(aa));
accy.setText(String.valueOf(bb));
accz.setText(String.valueOf(cc));
}
});
}
the problem is... i can get the determined values but cannot get the updated values of sensor change ?
sorry for rooky question, any help will be appritiated

this is the main Class

}
}

you can use the concept of common class in this case and I believe it will solve your problem quite easily. Follow to steps below.
Make a public class and declare an array of double inside it which you need to access in another class
Public class Common{
public static List<double> acce;
}
and in your activity where the sensors give updated value use a temp list
and assign it to Common.acce;
Common.acce = tempList;
Now, when you need to access acce just use Common.acce, and the reference of tempList is in the Common.acce and when the data in tempList will be updated by your sensor the list in common will be also updated, so ultimately you will get the updated value.
Feel free to ask if something is unclear. And Kindly mark it as the correct answer if it helps you so that in future this answer can help other needy. Happy Coding 😀.

#Override

falseRow44 = findViewById(R.id.falseRow44);
falseRow45 = findViewById(R.id.falseRow45);
falseRow43 = findViewById(R.id.falseRow43);

falseRow56 =findViewById(R.id.falseRow56);
animImage = findViewById(R.id.animImage);
animImage.setBackgroundResource(R.drawable.question_mark);
animationDrawable = (AnimationDrawable) animImage.getBackground();
context = ExerciseWithExplain1.this;
ad = new AlertDialog.Builder(context);
ad.setTitle(R.string.explainLogic);
ad.setMessage(R.string.logicForAnd);
final int ir = 0;
falseRow56.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
animImage.setVisibility(View.VISIBLE);
animationDrawable.start();
ad.show();
}
});
trueRow56.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
animImage.setVisibility(View.VISIBLE);
animationDrawable.start();
}
});
falseRow55.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
animImage.setVisibility(View.VISIBLE);
animationDrawable.start();
}
});

You can Try it by using Custom AnimationDrwable
import android.graphics.drawable.AnimationDrawable;
import android.os.Handler;
public abstract class CustomAnimationDrawableNew extends AnimationDrawable {
/** Handles the animation callback. */
Handler mAnimationHandler;
public CustomAnimationDrawableNew(AnimationDrawable aniDrawable) {
/* Add each frame to our animation drawable */
for (int i = 0; i < aniDrawable.getNumberOfFrames(); i++) {
this.addFrame(aniDrawable.getFrame(i), aniDrawable.getDuration(i));
}
}
#Override
public void start() {
super.start();
/*
* Call super.start() to call the base class start animation method.
* Then add a handler to call onAnimationFinish() when the total
* duration for the animation has passed
*/
mAnimationHandler = new Handler();
mAnimationHandler.post(new Runnable() {
#Override
public void run() {
onAnimationStart();
}
});
mAnimationHandler.postDelayed(new Runnable() {
#Override
public void run() {
onAnimationFinish();
}
}, getTotalDuration());
}
/**
* Gets the total duration of all frames.
*
* #return The total duration.
*/
public int getTotalDuration() {
int iDuration = 0;
for (int i = 0; i < this.getNumberOfFrames(); i++) {
iDuration += this.getDuration(i);
}
return iDuration;
}
/**
* Called when the animation finishes.
*/
public abstract void onAnimationFinish();
/**
* Called when the animation starts.
*/
public abstract void onAnimationStart();
}
Now Use it like this code.
TextView tv = (TextView) findViewById(R.id.iv_testing_testani);
tv.setOnClickListener(new OnClickListener() {
public void onClick(final View v) {
// Pass our animation drawable to our custom drawable class
CustomAnimationDrawableNew cad = new CustomAnimationDrawableNew(
(AnimationDrawable) getResources().getDrawable(
R.drawable.anim_test)) {
#Override
void onAnimationStart() {
// Animation has started...
}
#Override
void onAnimationFinish() {
// Animation has finished...
}
};
// Set the views drawable to our custom drawable
v.setBackgroundDrawable(cad);
// Start the animation
cad.start();
}
});

Get value of dice

I want make a Dice game, i have use a github project (https://github.com/dylanmtaylor/Simple-Dice).
The MainActivity is available here : https://github.com/dylanmtaylor/Simple-Dice/blob/master/src/com/dylantaylor/simpledice/RollDice.java
I want to get the value of the dice
Exemple :
If the first dice is 1 and the second is 6 we have a total of 7 i want make an action.
I have make a button who change a textview, this button try to get the number of the dices.
TextView hwTextView = (TextView)findViewById(R.id.textView8);
hwTextView.setText(String.valueOf(diceSum));
I have try to get the value "diceSum", "diceImages", "dice", "dice[roll[0]", "dice[roll[1]" but that didn't show a number.

I didn't understand why your code didn't work. I myself making a very small games based on "Scarne's dice game(pig)" and myself facing the challenge of retrieving the value of dice rolled. Mind, I am just using one die. This is what I did:
int userScore;
private int[] diceArray = {R.drawable.d1, R.drawable.d2, R.drawable.d3,
R.drawable.d4,R.drawable.d5,R.drawable.d6};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void onRollBtnClicked() {
ImageView diceFace = (ImageView) findViewById(R.id.diceFaceImageView);
userScore = randomIntegerGenerator(1,6); // this is what you need
diceFace.setImageResource(diceArray[userScore]);
}
// function to return random integer from min to max
public int randomIntegerGenerator(int min, int max) {
return random.nextInt((max - min) + 1) + min;
}
I am storing my rolled die value in userScore. You can use the similar approach.

My Calculations are off when Creating a BMI Calculator

Problem: My Calculations are off when I compared the results on my app to the bmi website. THank you so much in advance, also my math is really bad so I apologize in advance.
Here are the results that my app is giving me:

You don't use the same formula. Try this:
float bmi = weight * 703f / (float)Math.pow(heightIN+12f*v,2);
The formula above can be found here.
I hope it helps.

How can I create an animation class to use in other activities in android?

I have this animation activity for falling images. It works perfectly. What I would like to is change this, so I can call something like, startImageFallAnimation(), in another activity, and have it show over the current activity. I'd hate to have to add all this code to every activity I want to use it in. I experimented for a few hours, with no luck.
How can I accomplish this?
import com.tmp.animation.R;
public class FallAnimationActivity extends Activity {
// 100 = lots falling / 1000 = less falling
public int imageInterval = 100;
private int[] LEAVES = {
R.drawable.coin,
R.drawable.starsm,
//R.drawable.leaf_yellow,
//R.drawable.leaf_other,
};
private Rect mDisplaySize = new Rect();
private RelativeLayout mRootLayout;
private ArrayList<View> mAllImageViews = new ArrayList<View>();
private float mScale;
#Override

EDIT- After lots of work, this is the best I've got, but I cant solve passing context into the handler, or passing the layout into the first method.

Create a Java class with static method startImageFallAnimation(),where you will write all your animation code and just call the method wherever it is required

The quickest solution I can think of would be to make the target Activities extend this class and change the access level of the member variables in FallAnimationActivity to 'protected'. Depending on whether you need this in all/most Activities, I'd put the logic in a base class.

have context as a parameter in your util class
example:
public animation(Imageview imageview, Context mContext)
{
Animation slideLeft = AnimationUtils.loadAnimation(mContext, R.anim.slide_out_left);
imageview.startAnimation(slideLeft);
}
then in the activity you want to call it in do
// for activity
Utils.animation(Your image view, this)
//for fragment
Utils.animation(Your image view, getContext)
my utility class is called Utils, so you type whatever you named the class and call the method accordingly
