I have roulette (ImageView) with count of scrolls. When I tap on the button once roulette starts to round on 270 degree. When I tap on the button again, roulette must speeds up and round more. How to realise speed up of scrolling after start first animation and decrement count of scrolling after full end of animation?
I am having trouble understanding exactly what you want to do as you did not provide any code to reference that shows an error, but this should do what you are asking in terms of allowing your image to rotate faster as you continually click a "rotate" button.
I have used ObjectAnimator
activity_main.xml:
<ImageView
android:id="#+id/imageView_roulette"
android:layout_width="300dp"
android:layout_height="300dp"
android:src="#mipmap/ic_launcher"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent" />
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Start Rotation"
app:layout_constraintTop_toBottomOf="#+id/imageView_roulette"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toLeftOf="#+id/buttonStop"
app:layout_constraintRight_toRightOf="parent"
/>
<Button
android:id="#+id/buttonStop"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Stop"
app:layout_constraintTop_toBottomOf="#+id/imageView_roulette"
app:layout_constraintLeft_toRightOf="#+id/button"
app:layout_constraintRight_toRightOf="parent"
/>
</android.support.constraint.ConstraintLayout>
MainActivity.java:
public class MainActivity extends AppCompatActivity {
Boolean rotating = false;
Integer durationOfSpin = 3000; //default 3000
ImageView image;
ObjectAnimator animation;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button buttonStart = (Button) findViewById(R.id.button);
Button buttonStop = (Button) findViewById(R.id.buttonStop);
image = (ImageView) findViewById(R.id.imageView_roulette);
buttonStart.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
if(!rotating) {
rotating = true;
animation = ObjectAnimator.ofFloat(
image, "rotation", 0, 360);
animation.setDuration(durationOfSpin);
animation.setInterpolator(new LinearInterpolator());
animation.setRepeatCount(Animation.INFINITE);
animation.start();
}else{
if(durationOfSpin - 300 > 0) {
durationOfSpin -= 300; //make slightly faster each subsequent click
}
animation.setDuration(durationOfSpin);
}
}
});
buttonStop.setOnClickListener(new Button.OnClickListener() {
//just here so you can cancel your rotation
public void onClick(View v) {
if(rotating) {
rotating = false;
durationOfSpin = 3000; //set back to default
animation.cancel();
}
}
});
}
}

i am developing a roulette game for learning while my friend ask me to make spinning wheel shape from circle to oval. after changing shape of ImageView to an oval and trying to rotate ,it's height and width are swapping according to each 90-degree rotation. while height and width should not change as i need, following are codes i am using and screenshot attached
thanks for your time .

UI i want even when rotation
I am using a progress bar sample from Github however I noticed that the progress bar fill is set to a fixed value. For example, if the step count goal is 10 (.java class) the man should be "10" in the .XML
My goal: when the user inputs their goal step count, the "10" should be variable and change depending on user input.
java snippet:
ProgressBar progressBar = (ProgressBar) this.findViewById(R.id.progressBar);
ObjectAnimator animation = ObjectAnimator.ofInt(progressBar, "progress", lastStep, stepCounter); //animate only from last known step to current step count
animation.setDuration(5000); // in milliseconds
animation.setInterpolator(new DecelerateInterpolator());
animation.start();
lastStep = stepCounter;
XML snippet
<ProgressBar
android:id="#+id/progressBar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="376dp"
android:layout_height="392dp"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:max="10"
android:progress="0"
android:progressDrawable="#drawable/circular" />
EDIT********************EDIT
Sorry maybe my question wasn't clear. To provide an example...if the users step goal is 500. I need the progress bar to fill respectively. Therefore, IF step_count = 250 then progress bar should be half full, IF step_count = 750 then should be 3/4 full. I need the progression to be respective to a variable value.

I have a problem with creating 2 activities for 1 button. I created a button and I managed to connect that button with one activity but I dont know how to add another activity to the same button.. What am I trying to do is that when we press on that button it will start playing animation (I managed to do that) but I also want it to send SMS to a specific number. I have code for that, but I dont know how to include / connect everything together.
Code from a button:
<Button
android:id="#+id/button"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/transparent" />
Code from a imageview (animation):
<ImageView
android:id="#+id/imageView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:layout_gravity="center"
android:scaleType="centerInside"
android:src="#drawable/keers" />
Code from main activity, for animation:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
imageView = (ImageView) findViewById(R.id.imageView);
button = (Button) findViewById(R.id.button);
running = false;
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
if(!running){
((AnimationDrawable) imageView.getDrawable()).start();
running = true;}
}
}
);
}
}
Now what I want to add for the same button is this :
public void sendText(View paramView)
{
Toast.makeText(this, "SENT",Toast.LENGTH_SHORT).show();
SmsManager.getDefault().sendTextMessage("+3564245237",null,"1", null, null);
I'm not that experienced in programming, so it might be pretty easy for you guys.
Both actions seen to be fired by the same Button, so you may add both to the onClickListener
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
if(!running){
((AnimationDrawable) imageView.getDrawable()).start();
running = true;}
Toast.makeText(view.getContext(), "SENT",Toast.LENGTH_SHORT).show(); //Or YourActivity.this
SmsManager.getDefault().sendTextMessage("+3564245237",null,"1", null, null);
}
}
I'm making a simple "novelty" app that counts how many sneezes are done, it's more of a fun app that builds up experience until I do my huge project during the summer. I have two buttons, one adds a sneeze and the other clears how many sneezes there currently are. It holds the highest number of sneezes that there were previously. The problem is, the TextViews never update, they only initialize to zero. I used a Toast.makeText() to make sure that the buttons are working (they are). Any help is appreciated. Thanks

public void onClick(View v)
{
current_number += 1;
Toast.makeText(MainActivity.this, "Button Clicked " + current_number, Toast.LENGTH_SHORT).show();
}
});
clear_1.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
current_number = 0;
Toast.makeText(MainActivity.this, "Button Clicked", Toast.LENGTH_SHORT).show();
}
});

You need to update the text of the TextViews inside the onClickListeners. In fact, all your logic for counting, clearing, and recording the record needs to be done in your onClickListeners (or methods called by them). Right now you only do it once in onCreate, then never again. You can do this in onCreate:
final TextView cur_text = (TextView) findViewById(R.id.current_num);
add_one.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
current_number += 1;
cur_text.setText(Integer.toString(current_number);
}
});
And similar for the other TextView & onClickListener.
You only set the contents of your TextViews once. You should update them every time you get a click event. Specifically:
add_one.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
current_number += 1;
if (current_number >= record_number)
{
record_number = current_number;
rec_text.setText(String.valueOf(record_number));
}
cur_text.setText(String.valueOf(current_number));
}
});
clear_1.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
current_number = 0;
cur_text.setText(String.valueOf(current_number));
}
});
NOTE: if your variables current_number, record_number, cur_text, and rec_text aren't already declared as class member variables, you'll want to do that do that so that they're accessible once you leave the scope of the method you're doing all this in (I assume it's onCreate(...).
What you are going to need to do here is update the labels during the on click events of the button. You currently only update them on activity create. This doesn't execute every time there is a click. Can I answer any questions about the fixed up version below?
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_main);
final TextView rec_text = (TextView) findViewById(R.id.record_num);
final TextView cur_text = (TextView) findViewById(R.id.current_num);
Button add_one = (Button) findViewById(R.id.addone);
Button clear_1 = (Button) findViewById(R.id.clear);
add_one.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
current_number += 1;
if (current_number >= record_number)
record_number = current_number;
cur_text.setText(String.valueOf(current_number));
rec_text.setText(String.valueOf(record_number));
}
});
clear_1.setOnClickListener(new OnClickListener() {
public void onClick(View v)
{
current_number = 0;
cur_text.setText(String.valueOf(current_number));
rec_text.setText(String.valueOf(record_number));
}
});
cur_text.setText(String.valueOf(current_number));
rec_text.setText(String.valueOf(record_number));
}
I am developing a game in Android in which the launcher screen has 2 AnimationDrawables on it.
The animations run fine together, however when I navigate away from the screen and then hit back to return to it, one of the animations stops, and the other continues.
My code is below:
static AnimationDrawable animation;
static AnimationDrawable animation2;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.menu);
animation = new AnimationDrawable();
animation.addFrame(getResources().getDrawable(R.drawable.j0), 200);
animation.addFrame(getResources().getDrawable(R.drawable.j1), 200);
animation.addFrame(getResources().getDrawable(R.drawable.j2), 200);
animation.addFrame(getResources().getDrawable(R.drawable.j3), 200);
animation.setOneShot(false);
animation2 = new AnimationDrawable();
animation2.addFrame(getResources().getDrawable(R.drawable.logo), 250);
animation2.addFrame(getResources().getDrawable(R.drawable.logo1), 250);
animation2.setOneShot(false);
ImageView imageAnim = (ImageView) findViewById(R.id.imageView1);
imageAnim.setBackgroundDrawable(animation);
imageAnim.post(new MenuAnimate());
ImageView imageAnima = (ImageView) findViewById(R.id.imageView2);
imageAnima.setBackgroundDrawable(animation2);
imageAnima.post(new MenuAnimate2());
class MenuAnimate implements Runnable {
public void run() {
Menu.animation.start();
}
}
class MenuAnimate2 implements Runnable {
public void run() {
Menu.animation2.start();
}
}
Xml 'menu':
<LinearLayout android:orientation="horizontal" android:layout_height="fill_parent" android:layout_width="wrap_content" android:weightSum="1" android:layout_weight="0.93">
<ImageView android:id="#+id/imageView1" android:layout_height="match_parent" android:layout_width="wrap_content"></ImageView>
<ImageView android:id="#+id/imageView2" android:layout_height="wrap_content" android:layout_width="wrap_content" android:layout_gravity="bottom"></ImageView>
</LinearLayout>
If anyone has any idea it would be amazing.
