I want to load last chapter when pull down and load next chapter when pull up,but get some problems, when I inited the first page ,then I pull up to load last chapter, the recyclerview not call onScrolled. But if I pull down small distance then pull down ,I can get the result ,here is my code:
recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
#Override
public void onScrolled (RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
if(dy < 0 && mLayoutManager.findFirstCompletelyVisibleItemPosition() == 0) {
getNextChapter();
}
if(dy > 0 &&
mLayoutManager.findLastCompletelyVisibleItemPosition() ==
mAdapter.getItemCount() - 1) {
getNextChapter();
}
Logger.i("onScrolled:" + dy);
}
});

I were trying to make a camera application, I'm unable to find a way to change camera brightness, contrast using Camera.Parameters
So my question is how to add Brightness and contrast feature to increase/decrease brightness/contrast. For example if I increase the seekbarit increase the brightness. if I decrease the seekbar it decrease the brightness.
Please edit my code or put your seprate answer to help me.

I am working on RecyclerView swipe to show an action button behind list items and my RecyclerView is in a fragment with Bottom Navigation and everything is going well but sometimes swipe stops and gets stuck so I can't completely swipe the item. I need your help with this. My codes:
The code in main activity:
ItemTouchHelper itemTouchhelper = new ItemTouchHelper(swipeController);
itemTouchhelper.attachToRecyclerView(movelistview);
movelistview.addItemDecoration(new RecyclerView.ItemDecoration() {
#Override
public void onDraw(Canvas c, RecyclerView parent, RecyclerView.State state) {

I have had the same problem. swipe button stuck in UI, Behind recyclerview. So here is the easy and best solution ever i found.
create new Function in SwipeViewController as below
public void setSwipeBack()
{
swipeBack = false;
buttonShowedState = ButtonsStates.GONE;
}
and use this function in your fragment where your are filling data in the same recycler view.
as below
setSwipeBack();
I had the same problem, but the solution turned out to be easy.
This will happen when parent container will intercept your touch event. Any ViewGroup that overrides ViewGroup.onInterceptTouchEvent(MotionEvent) can do that (RecyclerView or ScrollView for instance).
And this will result in returning ACTION_CANCEL from your motionEvent when the Y value slightly changes, and sending touch events to parent view.
Proper way to deal with this is to call ViewParent.requestDisallowInterceptTouchEvent(boolean) method on your parent view once you think you need to keep the motion event.
Here's a quick example (attemptClaimDrag() method is taken from android source code):
/**
* Tries to claim the user's drag motion, and requests disallowing any
* ancestors from stealing events in the drag.
*/
private void attemptClaimDrag() {
// parent = yourView.getParent();
if (parent != null) {
parent.requestDisallowInterceptTouchEvent(true);
}
}
And in your onTouchEvent() or onTouch():
#Override
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
if (iWantToKeepThisEventForMyself(event)) {
attemptClaimDrag();
}
//your logic here
} else {
//your logic here
}
}
I modified a little bit the Real Time Line Chart example to show two LineChart like the code below.
Problem: the ViewPort is moving incorrectly does not work properly. It is moving much faster than real points (Entry) are added. In other words, the Entry get added in the wrong place and the ViewPort keeps moving right uncontrollably. It should move right only gradually as each Entry is added. Please help me to fix this one.

if (set == null) {

data.addDataSet(set);
}
String xValue = sdf.format(new Date());
// add a new x-value first
data.addXValue(xValue);
set.addEntry(new Entry(value, set.getEntryCount(), 0));
// let the chart know it's data has changed
mChart.notifyDataSetChanged();
// limit the number of visible entries
mChart.setVisibleXRangeMaximum(30);
// mChart.setVisibleYRange(30, AxisDependency.LEFT);
// move to the latest entry
mChart.moveViewToX(data.getXValCount() - 31);

Resolved in the comments by #Tony with the following change:
//set.addEntry(new Entry(value, set.getEntryCount(), 0)); //incorrect
set.addEntry(new Entry(value, data.getXValCount(), 0)); //correct
Explanation:
A LineData is composed of multiple ILineDataSet:
set.getEntryCount() returns the number of y-values in one DataSet and is effectively equivalent to yvals.size().
data.getXValCount() returns the total number of x-values the ChartData object represents.
Since we wish to add an entry at the last x-index, we should use data.getXValCount()
NOTE:
In MPAndroidCharts 3.0.1 data.getXValCount() is no longer present. You can instead use data.getXMax() + 1 instead.
I want to implement in my 2d jump and run game that my player can shoot but I always get a null pointer exception.
Does anyone know why?
In this class I check for input:
public class InputIngame implements InputProcessor {
Player player;
public void handleInput(){
//control our player using immediate impulses
if (Gdx.input.isKeyJustPressed(Input.Keys.W) && PlayScreen.player.b2body.getLinearVelocity().y == 0)
PlayScreen.player.b2body.applyLinearImpulse(new Vector2(0, 6f), PlayScreen.player.b2body.getWorldCenter(), true);
if (Gdx.input.isKeyPressed(Input.Keys.D) && PlayScreen.player.b2body.getLinearVelocity().x <= 2)
PlayScreen.player.b2body.applyLinearImpulse(new Vector2(0.2f, 0), PlayScreen.player.b2body.getWorldCenter(), true);
if (Gdx.input.isKeyPressed(Input.Keys.A) && PlayScreen.player.b2body.getLinearVelocity().x >= -2)
PlayScreen.player.b2body.applyLinearImpulse(new Vector2(-0.2f, 0), PlayScreen.player.b2body.getWorldCenter(), true);
if (Gdx.input.isKeyPressed(Input.Keys.D) && Gdx.input.isKeyPressed(Input.Keys.SHIFT_LEFT) && PlayScreen.player.b2body.getLinearVelocity().x > 1)
PlayScreen.player.b2body.setLinearVelocity(1, PlayScreen.player.b2body.getLinearVelocity().y);
if (Gdx.input.isKeyPressed(Input.Keys.A) && Gdx.input.isKeyPressed(Input.Keys.SHIFT_LEFT) && PlayScreen.player.b2body.getLinearVelocity().x < -1)
PlayScreen.player.b2body.setLinearVelocity(-1, PlayScreen.player.b2body.getLinearVelocity().y);
if (Gdx.input.isKeyJustPressed(Input.Keys.SPACE))
player = new Player();
player.fire();
}
in my screen class I draw the fireball:
#Override
public void render(float delta) {
//separate our update logic from render
update(delta);
//Clear the game screen with Black
Gdx.gl.glClearColor(0, 0, 0, 1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
//render our game map
renderer.render();
if (player.isDead == true)
player.die();
player.draw(runner.batch);
//renderer our Box2DDebugLines
b2dr.render(world, gamecam.combined);
runner.batch = new SpriteBatch();
runner.batch.setProjectionMatrix(gamecam.combined);
runner.batch.begin();
player.draw(runner.batch);
runner.batch.end();
if (TimeUtils.timeSinceNanos(startTime) > 1000000000) {
startTime = TimeUtils.nanoTime();
}
Gdx.app.log("FPSLogger", "fps: " + Gdx.graphics.getFramesPerSecond());
}
In my player class I set my variables:
private PlayScreen screen;
private Array<FireBall> fireballs;
And init them:
public Player(PlayScreen screen){
//initialize default values
runner = new HardwareRunner();
this.screen = screen;
fireballs = new Array<FireBall>();
And this method is execudet in the render method:
public void update(float dt){
//update our sprite to correspond with the position of our Box2D body
setPosition(b2body.getPosition().x - getWidth() / 2, b2body.getPosition().y - getHeight() / 2);
//update sprite with the correct frame depending on marios current action
setRegion(getFrame(dt));
for(FireBall ball : fireballs) {
ball.update(dt);
}
}
And there are also these methods:
public void fire(){
fireballs.add(new FireBall(screen, b2body.getPosition().x, b2body.getPosition().y, runningRight ? true : false));
}
public void draw(Batch batch){
super.draw(batch);
for(FireBall ball : fireballs)
ball.draw(batch);
}
And then theres my fireball class:
public class FireBall extends Sprite {
PlayScreen screen;
World world;
Array<TextureRegion> frames;
Animation fireAnimation;
float stateTime;
boolean destroyed;
boolean setToDestroy;
boolean fireRight;
Body b2body;
public FireBall(PlayScreen screen, float x, float y, boolean fireRight){
this.fireRight = fireRight;
this.screen = screen;
this.world = screen.getWorld();
frames = new Array<TextureRegion>();
for(int i = 0; i < 4; i++){
frames.add(new TextureRegion(screen.getAtlas().findRegion("fireball"), i * 8, 0, 8, 8));
}
fireAnimation = new Animation(0.2f, frames);
setRegion(fireAnimation.getKeyFrame(0));
setBounds(x, y, 6 / HardwareRunner.PPM, 6 / HardwareRunner.PPM);
defineFireBall();
}
public void defineFireBall(){

setToDestroy();
}

I hope anyone can help me!
i think your problem is you forget brakets in "if" condition try this :
if (Gdx.input.isKeyJustPressed(Input.Keys.SPACE)) {
player = new Player();
player.fire();
}
good luck ;
if any trouble leave a comment ;)
I have a simple game where the player needs to collect 4 game objects within 30 sec. Now I already created the timer, so I need to let the game know that if all game objects are collected under the time limit the player wins.
This is my code so far:
using UnityEngine;
using System.Collections;
public class GameState : MonoBehaviour
{
public static int count = 0;
public float seconds = 30;
public float minutes = 0;
// Use this for initialization
void Start ()
{
}
// Update is called once per frame
void Update ()
{
if (seconds <= 0)
{
seconds = 30;
if (minutes >= 1)
{
minutes -- ;
}
else
{
minutes = 0;
seconds = 0;
GameObject.Find("TimerText").guiText.text = minutes.ToString("f0") + ":0" + seconds.ToString("f0");
}
}
else
{
seconds -= Time.deltaTime;
}
if (Mathf.Round(seconds) <=9)
{
GameObject.Find("TimerText").guiText.text = minutes.ToString("f0") + ":0" + seconds.ToString("f0");
}
else
{
GameObject.Find("TimerText").guiText.text = minutes.ToString("f0") + ":" + seconds.ToString("f0");
}
if(count >= 1)
{
print("You Won!");
}
}
void OnTriggerEnter(Collider collide)
{
if (collide.transform.tag == "Cube")
{
count = count + 1;
Destroy (collide.gameObject);
}
}
}
Note: cube is one of the game object that needs to be picked up.
you could interrupt the game or show a victory menu or something when you have all the cubes collected
void Update ()
{
bool cubescollected = false;
if(cubescollected == 4)
{
ShowVictoryOrSomething();
cubescollected = true
}
if(cubescollected == true)
return;
... your timer code
}
good luck and happy coding
