I need to make a 2048 game in Android.
For the Board we need use a GridLayout and set it up programatically.
It will be a 4x4 grid just like the original game.
For the card we have to use a FrameLayout with a TextView and center it.

This is what I already have:
public class Board extends GridLayout {
private final int BOARD_WIDTH = 4;
private final int BOARD_HEIGHT = 4;
private Card[][] cards;
public Board(Context context) {
super(context);
initBoard();
}
public Board(Context context, AttributeSet attrs) {
super(context, attrs);
initBoard();
}
public Board(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
initBoard();
}
public void initBoard() {
this.setBackgroundColor(ContextCompat.getColor(getContext(), R.color.colorBoard));
this.setRowCount(BOARD_HEIGHT);
this.setColumnCount(BOARD_WIDTH);
Random random = new Random();
cards = new Card[BOARD_WIDTH][BOARD_HEIGHT];
for (int x = 0; x < BOARD_WIDTH; x++) {
for (int y = 0; y < BOARD_HEIGHT; y++) {
int n = random.nextInt(2);
cards[x][y] = new Card(this.getContext(), (n * 2));
}
}
}
public void addCardsToBoard() {
for (int x = 0; x < BOARD_WIDTH; x++) {
for (int y = 0; y < BOARD_HEIGHT; y++) {
GridLayout.LayoutParams param = new LayoutParams();
param.height = LayoutParams.WRAP_CONTENT;
param.width = LayoutParams.WRAP_CONTENT;
param.setGravity(Gravity.CENTER);
param.columnSpec = GridLayout.spec(x);
param.rowSpec = GridLayout.spec(y);
param.topMargin = 50;
Card c = cards[x][y];
c.setLayoutParams(param);
this.addView(cards[x][y], 230, 230);
}
}
}
}
-
public class Card extends FrameLayout {
private int number = 0;
private TextView txtNumber;
public Card(Context context, int n) {
super(context);
LayoutParams params = new LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
params.gravity = Gravity.CENTER;
txtNumber = new TextView(context);
txtNumber.setTextSize(30);
txtNumber.setLayoutParams(params);
this.addView(txtNumber);
setNumber(n);
}
public int getNumber() {
return number;
}
public void setNumber(int number) {
this.number = number;
this.setBackgroundColor(ContextCompat.getColor(getContext(), number == 0 ? R.color.colorCard : R.color.colorCardActive));
txtNumber.setText(number == 0 ? "" : "" + number);
}
}
Anything I can do to make it look better (more like the original game).
Any tips/advice is appreciated.
Add horizontal and vertical spacing to GridLayout, that is applicable to it's column and row.
view.setHorizontalSpacing(10);
view.setVerticalSpacing(10);

I have the following GridLayout which stores a number of 6 maximum columns :
<androidx.gridlayout.widget.GridLayout
android:id="#+id/pokemonTeambuilderSpritesLayout"
android:layout_width="match_parent"
android:layout_height="100dp"
app:columnCount="6"
app:rowCount="1"
app:useDefaultMargins="true" />
And here I populate it :
List<Pokemon> pokemonList = pokemonTeam.getPokemonList();
for (Pokemon pokemon : pokemonList) {
CircularImageView ivPokemonSprite = new CircularImageView(mContext);
String pokemonId = pokemon.get_id();
int pokemonImageId = PokemonUtils.getPokemonSugimoriImageById(pokemonId, mContext);
Picasso.get().load(pokemonImageId).into(ivPokemonSprite);
GridLayout.LayoutParams layoutParams = new GridLayout.LayoutParams(
GridLayout.spec(GridLayout.UNDEFINED, 1f),
GridLayout.spec(GridLayout.UNDEFINED, 1f)
);
layoutParams.width = 0;
ivPokemonSprite.setLayoutParams(layoutParams);
holder.teamSpritesGridLayout.addView(ivPokemonSprite);
}
My current output with 6 images is this :
With 3 images :
With 2 images:
My desired output would be :
For 6 images:
For 2 images:
For 4 images:
I want it to add them starting from left to right uniform and If the image doesn't have enough space to fit on its own I want it to "collide" with the others instead of letting margin between them (as you can see in the examples). Thats how I see that the GridLayoutManager works . How can I achieve this ?
you can create custom layout for handling your different cases. something like below:
public class PokemonLayout extends FrameLayout {
private int height;
private int width;
private int childWidth;
public PokemonLayout(Context context) {
this(context, null);
}
public PokemonLayout(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
public PokemonLayout(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
#TargetApi(Build.VERSION_CODES.LOLLIPOP)
public PokemonLayout(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
width = MeasureSpec.getSize(widthMeasureSpec);
height = Integer.MIN_VALUE;
childWidth = Integer.MIN_VALUE;
measureChildren(widthMeasureSpec, heightMeasureSpec);
int count = getChildCount();
for (int i = 0; i < count; i++) {
final View child = getChildAt(i);
height = Math.max(child.getMeasuredHeight(), height);
childWidth = Math.max(child.getMeasuredWidth(), childWidth);
}
setMeasuredDimension(MeasureSpec.makeMeasureSpec(width, MeasureSpec.EXACTLY), MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY));
}
#Override
protected void onLayout(boolean changed, int leftParent, int topParent, int rightParent, int bottomParent) {
int count = getChildCount();
boolean overlap = count * childWidth > width;
int widthOffset = childWidth;
if(overlap) {
widthOffset = childWidth - (Math.abs(width - (count * childWidth)) / (count-1));
}
for (int i = 0; i < getChildCount(); i++) {
View child = (View) getChildAt(i);
child.layout(i*widthOffset,
0,(i*widthOffset) + childWidth
, child.getMeasuredHeight());
}
}
}
For 3 images:
For 5 images:
UPDATE 1:
change onLayout method to positioning children at the center of layout
#Override
protected void onLayout(boolean changed, int leftParent, int topParent, int rightParent, int bottomParent) {
int count = getChildCount();
boolean overlap = count * childWidth > width;
int widthOffset = childWidth;
int startOffest = (width - (count * childWidth)) / 2;
if(overlap) {
startOffest = 0;
widthOffset = childWidth - (Math.abs(width - (count * childWidth)) / (count-1));
}
for (int i = 0; i < getChildCount(); i++) {
View child = (View) getChildAt(i);
child.layout(startOffest+ (i*widthOffset),
0,(i*widthOffset) + childWidth + startOffest
, child.getMeasuredHeight());
}
}
I'm coding a ring menu that is going to put together several different types of view, which will have all the same size. The thing is that it works perfectly with native views, like ImageView, but when I try to put a custom labeled image view, it simply doesn't appear int the custom ViewGroup. It's also worth mentioning that when this view is declared in the XML file, outside de custom ViewGroup it is shown just fine, but as soon as I put it inside the ViewGroup, or declare it programatically, it vanishes. My guess is that I'm doing something weong inside the onLayout method, but I can't put my finger on it, since all coordinates and view sizes are correct according to the Log.
The XML file for the CompoundView:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true"
android:focusable="true">
<ImageView
android:id="#+id/header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:src="#drawable/ropeiconselector"/>
<TextView
android:id="#+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="WWWWWWWWWWWW"
android:background="#color/button"
android:layout_marginLeft="-10dp"
android:layout_centerVertical="true"
android:layout_toRightOf="#id/header"
android:padding="8dp"
/>
The code for the CompoundView (I omitted some unimportant methods)
public class CircularLabeledImageView extends RelativeLayout implements View.OnClickListener {
ImageView headerView;
TextView labelView;
boolean isOpen = false;
String[] itemDesc;
int position;
int size;
int maxLabelWidth = 100;

super(context);
//EDIT Methhod called

CircularLabeledImageView ViewA = new CircularLabeledImageView(this);
ring.addView(ViewA);
This is my first question on here so don't go too hard on me :D
My plan is to make a seat plan for teachers, where the students are being shown. This seat plan is being created dynamically from a SQLiteDatabase. While approaches with GridView/GridLayout/TableLayout have all failed, now I'm just having a vertical LinearLayout, adding horizontal ones to it.
Now, in order to know the position of a student, I've been trying to extend from TextView, a class called SchuelerView (Schüler = student in German) that does the same as a normal TextView, simply with one more attribute: a Schueler.
If I do everything the same way, just by using TextViews, it works, but when it comes to my custom class, it doesn't work.
This is the SchuelerView code:
public class SchuelerView extends TextView {
private Schueler schueler;
private int posx, posy;
public SchuelerView(Context context) {
super(context);
}
public SchuelerView(Context context, AttributeSet attrs) {
super(context, attrs);
}
#Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
}
public int getPosx() {
return posx;
}
public int getPosy() {
return posy;
}
public void setPosx(int posx) {
this.posx = posx;
}
public void setPosy(int posy) {
this.posy = posy;
}
public void setSchueler(Schueler s) {
schueler = s;
posx = schueler.getPosx();
posy = schueler.getPosy();
}
public Schueler getSchueler() {
return schueler;
}
}
And this is the method that is using these views:
public void schuelerZuGrid() {
lv.removeAllViews(); // Vertikales LinearLayout
lv.setWeightSum(reihen);
for(int i = 0; i < reihen; i++) {
LinearLayout lh = new LinearLayout(this);
lh.setOrientation(LinearLayout.HORIZONTAL);
lh.setWeightSum(spalten); // DESIGN
lv.addView(lh);
for(int j = 0; j < spalten; j++) {
Cursor c = db.rawQuery("SELECT vorname, nachname, posx, posy, sid FROM Schueler, Hat "
+ "WHERE Hat.schuelerid = Schueler.sid AND Hat.kfid =" + kfid + " AND posx="+j+" AND posy="+i, null);
if(c.getCount() > 0) {
c.moveToFirst();
String vorname = c.getString(c.getColumnIndex("vorname"));
String nachname = c.getString(c.getColumnIndex("nachname"));
int posx = c.getInt(c.getColumnIndex("posx"));
int posy = c.getInt(c.getColumnIndex("posy"));
int sid = c.getInt(c.getColumnIndex("sid"));
c.close();
Schueler schueler = new Schueler(vorname, nachname, posx, posy, sid);
SchuelerView t = new SchuelerView(this);
t.setSchueler(schueler);
t.setText(vorname + " " + nachname);
t.setGravity(Gravity.CENTER); // DESIGN
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT, 1); // DESIGN
t.setLayoutParams(lp); // DESIGN
t.setOnClickListener(this);
lh.addView(t);
} else {
SchuelerView t = new SchuelerView(this);
t.setPosx(j);
t.setPosy(i);
t.setText("/");
t.setGravity(Gravity.CENTER); // DESIGN
t.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT, 1)); // DESIGN
t.setOnClickListener(this);
lh.addView(t);
}
}
}
}
As I've said, the only error I get is that I don't see anything on the Activity. However, the SQL statements all are being executed correctly, and as I've said, doing everything the same way, just with TextViews, works out fine.
Thank you in advance!
I've been trying to create a custom view that is to be used to indicate the battery level of a proprietary device.
So when the battery level of the device is read the method setPercentage(int batteryLevel) is called on the custom view :
The problem is that regardless of what value I set nothing seems to change in the custom view.
Here is the class :
public class RectangleView extends LinearLayout {
private ArrayList<ImageView> views = new ArrayList<ImageView>();
public RectangleView(Context context, AttributeSet attributeSet) {
super(context, attributeSet);
init(context);
}
public RectangleView(Context context) {
super(context);
init(context);
}
private void init(Context context) {
this.setOrientation(LinearLayout.HORIZONTAL);
for (int i = 0; i < 10; i++) {
ImageView loadingPiece = new ImageView(context);
loadingPiece.setBackgroundColor(Color.BLACK);
this.addView(loadingPiece);
LayoutParams layoutParams = (LayoutParams)loadingPiece.getLayoutParams();
layoutParams.weight = 1.0f;
layoutParams.height = this.getHeight();
layoutParams.width = 0;
loadingPiece.setLayoutParams(layoutParams);
views.add(loadingPiece);
}
}
public void setPercentage(int amountToShow) {
for (int i = 0; i < views.size(); i++)
if (i < amountToShow)
views.get(i).setVisibility(View.VISIBLE);
else
views.get(i).setVisibility(View.INVISIBLE);
}
}
Caling setPersentage(5) should show 5 imageviews - However nothing is changed and the view itself seems empty.
I think that happens because of the LayoutParams you used(getHeight() returning 0 at that moment). See if this makes a difference:
this.setOrientation(LinearLayout.HORIZONTAL);
for (int i = 0; i < 10; i++) {
ImageView loadingPiece = new ImageView(context);
loadingPiece.setBackgroundColor(Color.BLACK);
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(0,
LinearLayout.LayoutParams.FILL_PARENT, 1.0f);
this.addView(loadingPiece, lp);
views.add(loadingPiece);
}
I think it would be easier to use a simple view with a custom drawable for background and render that background differently depending on the percentage. Or why not use a ProgressBar?
Please help! I tried everything! :(
I've got a schedule Class, which is simply a custom ViewGroup (with custom onMeasure() and onLayout()), which enables me to place childs(=events) with LayoutParams for column/row start and column/row end. The number of childs and their LayoutParams depend on database entries.
Now I'm trying to add childs (events) from my database. I'd have to use a Cursor Adapter, so my schedule Class has to extend ListView, right? I tried that but the newView() method of the adapter is never called. Why not??
My custom ListView doesn't ask the adapter for childs, no childs are added. I also can't add the childs by hand calling schedule.addView() if I extend from AdapterView.
I'd be really (really) happy if someone could help!
Regards,
cody

You should not need to be extending ListView. You just want to add an instance of ListView to your layout.
It sounds like you might want to be using a SimpleCursorAdaptor, where you can map items in your custom view to the data model objects you want them to display.
See Binding to Data with Adapter and Hello ListView for some examples of the right ways to use adapters and ListViews.
