custom view placing horizontally central on RelativeLayout - android

I am trying to place my custom view horizontally centered on a Relative Layout.
However it does not appear centered, instead it is close to the left of the screen.
Below is my xml file:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="5sp"
tools:context=".FinalActivity" >
<ImageView
android:contentDescription="#string/none"
android:id="#+id/imageView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:layout_marginLeft="0px"
android:layout_marginTop="0px"
android:scaleType="fitXY"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:src="#drawable/oven_alt" />
<com.test.game.myviewx
android:id="#+id/xview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
/>
<ImageView
android:contentDescription="#string/none"
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:layout_marginLeft="0px"
android:layout_marginTop="0px"
android:scaleType="fitXY"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:src="#drawable/oven_ust" />
</RelativeLayout>
and here is the custom view class:
public class myviewx extends View
{
Context cntx;
public myviewx(Context context) {
super(context);
cntx = context;
// TODO Auto-generated constructor stub
}
public myviewx(Context context, #Nullable AttributeSet attrs) {
super(context, attrs);
cntx = context;
// TODO Auto-generated constructor stub
}
public myviewx(Context context, #Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
cntx = context;
}
#Override
protected void onDraw(Canvas canvas)
{
super.onDraw(canvas);
final String MY_PREFS_NAME = "MyPrefsFile";
SharedPreferences sharedPreferences = cntx.getSharedPreferences(MY_PREFS_NAME, Context.MODE_PRIVATE);
Integer pb = sharedPreferences.getInt("pb", 0);
Bitmap bitmap;
Resources res = getResources();
if (pb==1) {
bitmap = BitmapFactory.decodeResource(res, R.drawable.p1);
}
else {
bitmap = BitmapFactory.decodeResource(res, R.drawable.p2);
}
//int x=500;
//int y=500;
//int radius=250;
Paint paint=new Paint();
// Use Color.parseColor to define HTML colors
//paint.setColor(Color.parseColor("#CD5C5C"));
//canvas.drawRect (250,250, 750, 750, paint);
//paint.setColor(Color.parseColor("#CD000C"));
//canvas.drawCircle(x,x, radius, paint);
canvas.drawBitmap(bitmap, 0, 0, paint);
}
}
using parameter "android:layout_centerHorizontal="true"" , imageviews are centered but "com.test.game.myviewx" custom view is not centered.
what am I missing ?

I had the same problem and could not find a solution.
Ended up drawing the content of the view centered.
You can use "this.getWidth()" and then draw everything accordingly.

Can we create a canvas programmatically from a view in Android

I am trying to create a dummy view from already existing View.
Original Image:
Need to create dummy view like this.
I tried with paint and canvas.
public class MyView extends View {
Paint paint;
Path path;
public MyView(Context context) {
super(context);
init();
}
public MyView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public MyView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
private void init(){
paint = new Paint();
paint.setColor(Color.BLUE);
paint.setStrokeWidth(10);
paint.setStyle(Paint.Style.STROKE);
}
#Override
protected void onDraw(Canvas canvas) {
// TODO Auto-generated method stub
super.onDraw(canvas);
canvas.drawRect(30, 50, 200, 350, paint);
// canvas.drawRect(100, 100, 300, 400, paint);
//drawRect(left, top, right, bottom, paint)
}
}
But I cannot draw like this. Because some time image will be circle or Ovel or any shape. So, I need to deduct the existing view and draw new view as same. Can anyone help me to create a dummy view from existing view?
I am trying to do this for shimmer animation only. For facebook shimmer I need to give the view inside the shimmerFramelayout. But My view will be dynamic. So, I need to create a dummy view programmatically for every time. For facebook Shimmer:
<com.facebook.shimmer.ShimmerFrameLayout
android:id="#+id/shimmerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:ignore="MissingConstraints">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<!--add several shimmer placeholder layout -->
<include layout="#layout/shimmer_placeholder_layout"></include>
<include layout="#layout/shimmer_placeholder_layout"></include>
<include layout="#layout/shimmer_placeholder_layout"></include>
</LinearLayout>
</com.facebook.shimmer.ShimmerFrameLayout>
Here shimmer_placeholder_layout is static view. I need to create dynamic view.
Finally got the solution.
Here I attached the solution for someone will get benefit on this.
MyView class:
public class MyView extends View {
Paint paint;
ViewGroup viewGroup;
Context context;
List<Rect> rectList = new ArrayList<>();
public MyView(Context context, ViewGroup viewGroup) {
super(context);
this.viewGroup = viewGroup;
this.context = context;
init();
}
public MyView(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public MyView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
private void init() {
paint = new Paint();
paint.setColor(context.getResources().getColor(R.color.gray));
paint.setStrokeWidth(10);
paint.setStyle(Paint.Style.FILL);
for (int i = 0; i < viewGroup.getChildCount(); ++i) {
View child = viewGroup.getChildAt(i);
Rect rect = new Rect();
int x = (int) child.getX() - dpToPx(20);
int y = (int) child.getY() - dpToPx(20);
rect.left = x;
rect.top = y;
rect.right = x + child.getWidth();
rect.bottom = y + child.getHeight();
rectList.add(rect);
}
}
#Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
for (Rect rect : rectList) {
canvas.drawRect(rect, paint);
}
}
public static int dpToPx(int dp) {
return (int) (dp * Resources.getSystem().getDisplayMetrics().density);
}
}
My MainActivity:
ConstraintLayout constraintLayout;
ImageView imageView;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
constraintLayout = findViewById(R.id.parent_view);

How to draw a Line between two ImageViews by getting the positions of the ImageViews?

This is MainActivity.java code which gets the positions of the imagViews and tries to generate a lineView between the ImageViews by getting the coordinates of the ImageViews.
I'm getting the coordinates of the ImageViews but it's not showing the line between them.
public class MainActivity extends AppCompatActivity {
private ImageView one,two;
private LineView lineView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lineView=findViewById(R.id.lineView);
one=findViewById(R.id.one);
two=findViewById(R.id.two);
Random random = new Random();
int x=random.nextInt(500);
int y=random.nextInt(500);
one.setX(x);
one.setY(y);
int c=x;
int d=y;
PointF pointA=new PointF(c,d);
x=random.nextInt(500);
y=random.nextInt(500);
two.setX(x);
two.setY(y);
c=x;
d=y;
PointF pointB=new PointF(c,d);
lineView.setPointA(pointA);
lineView.setPointB(pointB);
lineView.draw();
}
}
This is activity_main.xml that contains the ImageViews and LineView.
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
<xmlns:android="http://schemas.android.com/apk/res/android"

<com.example.testing.LineView
android:id="#+id/lineView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.constraint.ConstraintLayout>
This is the Lineview.java code that generates the line view widget and its operations .
public class LineView extends View {
PointF pointA,pointB;
private Paint paint =new Paint();
public LineView(Context context) {
super(context);
}
public LineView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public LineView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
#Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
paint.setColor(Color.RED);
paint.setStrokeWidth(20);
canvas.drawLine(pointA.x,pointA.y,pointB.x,pointB.y,paint);
}
public void setPointA(PointF point)
{
pointA=point;
}
public void setPointB(PointF point)
{
pointB=point;
}
public void draw()
{
invalidate();
requestLayout();
}
}
You can do it in your view - put this View between your images:
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#android:color/black" />
The horizontal line between two image views in android
<View
android:layout_width="match_parent"
android:layout_height="1dp"
android:background="#FF0000FF"/>
The vertical line between two image views in android
<View
android:layout_width="1dp"
android:layout_height="match_parent"
android:background="#FF0000FF"/>

Linking XML with Component View

I'm currently struggling with what I believe should be pretty simple.
I have created a LinearLayout in an XML file that i want to link to a CustomComponent that extends LinearLayout, meaning i started backwards.
Normally i create a CustomComponent first and this creates an XML-file linked by a tag, <my.package.CustomComponent> (If I'm not mistaken this is the only way they are linked(?)) and i do stuff in the onDraw(). But in this project i do the layout throughthe XML and not the onDraw().
Linking XML with activity is done by setContentView(R.layout.customView) but I can't really do this in a CustomComponent as i don't have an onCreate() method inherited.
sidenote: In the XML all my imagebuttons has android:onClick=chooseButton but for obvious reason it can't find this method...
Any ideas regarding this problem?
EDIT:
the two files doesn't seem to be linked because in the xml android:onClick="chooseButton" the IDE says: "cannot resolve symbol chooseButton"

Ripple animation effect over MapView

Is there a way to create a ripple effect over the MapView?
My layout is presented in the end of the post.
I know about android:background="?attr/selectableItemBackground" and it works great on different kinds of Views, but not with the MapView.
What I want is the indivisible ripple effect over header_container and map_view.
To reach this I have tried putting them inside RelativeLayout and creating View with selectableItemBackground above them, but I don't like this solution because I could only make it work by specifying the exact height of that overlapping view and I want it to match the height of header and map.

the following class is a recipe to put any overlay on top of any view.
All you have to do is replace extends View to extends Anything and then call setOverlay(...); with the overlay (in you specific question a Ripple).
so in your case it will be:
extends MapView
and then
mapView.setOverlay(mapView.getResources().getDrawable(R.drawable.ripple));
and here is the "recipe" class
public class PressedStateView extends View {
public PressedStateView(Context context) {
super(context);
}
public PressedStateView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public PressedStateView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
#TargetApi(Build.VERSION_CODES.LOLLIPOP)
public PressedStateView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
super(context, attrs, defStyleAttr, defStyleRes);
}
private Drawable overlay;
public void setOverlay(Drawable overlay) {
if (this.overlay != null) {
this.overlay.setCallback(null);
}
this.overlay = overlay;
this.overlay.setCallback(this);
this.overlay.setBounds(0, 0, getWidth(), getHeight());
invalidate();
}
#Override protected void onSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(w, h, oldw, oldh);
this.overlay.setBounds(0, 0, w, h);
}
#Override protected boolean verifyDrawable(Drawable who) {
return super.verifyDrawable(who) || who == overlay;
}
#TargetApi(Build.VERSION_CODES.LOLLIPOP) #Override
public void drawableHotspotChanged(float x, float y) {
super.drawableHotspotChanged(x, y);
if (overlay != null) {
overlay.setHotspot(x, y);
