Android - Bitmap - Fatal Signal 11 (SIGSEGV), code 1

Android - Bitmap - Fatal Signal 11 (SIGSEGV), code 1 - android

I have a project where I need a custom canvas (white sheet) like a view.
The activity will have two divisions
The aforementioned canvas.
A list/recycler view with images (ignore the temporary LinearLayout instead of list/recycler view)
So when I click on an Image. This image will get transferred to the canvas. Where user can drag, scale, rotate or do all of these together to that image. This canvas should support up to 4-5 images at the same time.
I would like to know if there is any better alternative or I am going to the right direction.
If I am going to the right direction. Please help me on this issue.

I think objects in WodrobHandler is empty. Where are code you add element?
You have to convert bitmap to mutable and avoid create bitmap in onDraw. Create it on Construtor. Code create bitmap mutable:
Bitmap. createScaledBitmap(souce,souce.getWidth(),source.getHeight,false);

I have two problems:
The drawing does it for me behind the image and not above

The background of the image is not full screen with margins.
How should I do?
Thanks

Android ImageView is rendering Bitmap images smaller while in ListView

I have a ListView, inside a linear layout, that should show items based on a list_item.xml layout file. In the layout file I have two ImageViews and two TextViews. I'm using my custom ArrayAdapter to fill the ListView at runtime with Bitmap images of scale 125x25, however images are showing smaller than their initial size when rendered by the ImageView inside the ListView as shown in the screenshot (of a single list item) below:

Usage:

ListView resultsListView = (ListView) findViewById(R.id.lvExp);
resultsListView.setAdapter(plateListAdapter);
plateListAdapter.addAll(recogInfo.getPlates());
plateListAdapter.notifyDataSetChanged();

Using definite dimensions for ImageView's, rather than wrap_content solved the problem.

How to avoid incorrect reusing of custom cells on MvxGridView?

I have the Android app page (on fragment) with MvxGridView with such layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<MvxGridView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/white"
android:numColumns="1"
android:horizontalSpacing="0dp"
android:verticalSpacing="0dp"
local:MvxBind="ItemsSource DayGraphsItems"
local:MvxItemTemplate="#layout/day_graph_item" />
</LinearLayout>
I have a custom view for drawing graph:
public class GraphView : View
{
Paint mPaint;
Bitmap mBitmap;
Canvas mCanvas;
Path mPath;
Paint mBitmapPaint;
public List<string> Data { get; set; }
public GraphView(Context context, Android.Util.IAttributeSet attributeSet) : base(context)
{
mPaint = new Paint();
mPaint.AntiAlias = true;
mPaint.Dither = true;
mPaint.SetARGB(0xFF, 0xFF, 0xFF, 0xFF);
mPaint.SetStyle(Paint.Style.FillAndStroke);
mPaint.StrokeJoin = Paint.Join.Round;
mPaint.StrokeCap = Paint.Cap.Round;
mPaint.StrokeWidth = 1;
mPaint.TextSize = 24;
mPath = new Path();
mBitmapPaint = new Paint();
mBitmapPaint.SetARGB(0xFF, 0xFF, 0xff, 0xff);
}
protected override void OnSizeChanged(int w, int h, int oldw, int oldh)
{
if (w > 0 && h > 0)
{
mBitmap = Bitmap.CreateBitmap(w, h, Bitmap.Config.Argb8888);
mCanvas = new Canvas(mBitmap);
_canvasHeight = h;
_canvasWidth = w;
DrawTheGraph(Data);
}
}
public override void Draw(Canvas canvas)
{
canvas.DrawBitmap(mBitmap, 0, 0, mBitmapPaint);
canvas.DrawPath(mPath, mPaint);
canvas.Restore();
}
private void DrawTheGraph(List<string> data)
{
// here is drawing of the graph which works well
}
}
I have the custom binding
public class GraphCustomBinding : MvxConvertingTargetBinding
{
public static string Name = "GraphCustom";
public GraphCustomBinding(GraphView target) : base(target)
{
}
protected override void SetValueImpl(object target, object value)
{
var data = new List<string>();
data = (List<string>)value;
var targetGraphView = (GraphView)target;
targetGraphView.Data = data;
}
public override Type TargetType
{
get { return typeof(GraphView); }
}
}
Binding is correctly registered in setup.
I have item's layout for the elements of DayGraphsItems list
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="15dp"
android:paddingRight="15dp"
android:paddingTop="15dp"
android:paddingBottom="15dp">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical|center_horizontal"
style="#style/TextViewCurrentConditionsHeader"
local:MvxBind="Text Title" />
<Pogoda.Droid.GraphView
android:layout_width="match_parent"
android:layout_height="300dp"
android:padding="5dp"
local:MvxBind="GraphCustom Data, Mode=TwoWay" />
</LinearLayout>
EDIT:
DayGraphsItems is a list of DayGraphItem which is given as follows:
public class DayGraphItem
{
public int Id { get; set; }
public string Title { get; set; }
public List<string> Data { get; set; }
}
View is on fragment:
[Register("pogoda.droid.DayGraphsFragment")]
public class DayGraphsFragment : BaseFragment<DayGraphsViewModel>
{
public const string TAG = "DayGraphsFragmentTag";
public override string UniqueImmutableCacheTag
{
get
{
return TAG;
}
}
public override Android.Views.View OnCreateView(Android.Views.LayoutInflater inflater, Android.Views.ViewGroup container, Android.OS.Bundle savedInstanceState)
{
base.OnCreateView(inflater, container, savedInstanceState);
return this.BindingInflate(Resource.Layout.day_graphs_layout, null);
}
}
Problem: The graphs are drawn correctly, but in the case when there are more cells than could be displayed at once on the screen, after I scroll down I see the cells which was drawn before instead of new ones (seem to be reused).
QUESTION: How to avoid this and display fresh graphs instead of these "scrolled out from the top"?

Solution which works for me is
Create EnhancedMvxListView and replace MvxGridView using it in point 1.
public class EnhancedMvxListView : MvxListView
{
public EnhancedMvxListView(Context context, IAttributeSet attrs) : base(context, attrs, new EnhancedMvxAdapter(context))
{
}
public EnhancedMvxListView(Context context, IAttributeSet attrs, IMvxAdapter adapter) : base(context, attrs, new EnhancedMvxAdapter(context))
{
}
}
where EnhancedMvxAdapter is the following
public class EnhancedMvxAdapter : MvxAdapterWithChangedEvent
{
public EnhancedMvxAdapter(Context context) : base(context)
{
}
protected override View GetBindableView(View convertView, object dataContext, ViewGroup parent, int templateId)
{
templateId = GetTemplateId(dataContext);
var view = base.GetBindableView(convertView, dataContext, parent, templateId);
var context = dataContext as DayGraphItem;
view.FindViewById<TextView>(Resource.Id.graphTitle).Text = context.Title;
view.FindViewById<GraphView>(Resource.Id.graphDrawing).Data = context.Data;
return view;
}
private int GetTemplateId(object data)
{
return Resource.Layout.day_graph_item;
}
}
And finally in file in point 2. I've replaced
public List<string> Data { get; set; }
with
List<string> _data;
public List<string> Data
{
get
{
return _data;
}
set
{
if (value != null && value != _data)
{
_data = value;
if ((int)_canvasWidth == 0 || (int)_canvasHeight == 0)
return;
mBitmap = Bitmap.CreateBitmap((int)_canvasWidth, (int)_canvasHeight, Bitmap.Config.Argb8888);
mCanvas = new Canvas(mBitmap);
DrawTheGraph(Data);
}
}
}

How to change shape by controlling it from points and line

I have a trapezoid shape created in custom view using below code.
#Override
protected void onDraw(Canvas canvas) {
trapezoidPath.moveTo(0,0);
trapezoidPath.lineTo(getWidth() ,0);
trapezoidPath.lineTo(getWidth() , altitude);
trapezoidPath.lineTo(0,getHeight());
trapezoidPath.lineTo(0,0);
trapezoidPath.close();
canvas.drawPath(trapezoidPath,paintTrapezoid);
}
The drawn shape looks like this.
I want to move (0,height) point to top until trapezoid shape become a rectangle. After that I want to move bottom line up until shape become a line.
Is there any way to access created path lines and it's point and manipulate them to achieve what I want ? If not how can I achieve this ?
I have to animate this shape base on user response. Thank you.

Use an ObjectAnimator to change the variables you use in onDraw. Below is an example of how you could implement this.
MainActivity.java

}
});
final Button animateButton = findViewById(R.id.btn_animate);
animateButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
animateButton.setEnabled(false);
resetButton.setEnabled(false);
trapezoidView.toNewState();
}
});
trapezoidView.setListener(new TrapezoidView.TrapezoidListener() {

Draw and animate a dashed line

I have a fullscreen activity that should look like this:
where the big white circle would have some text, I've already done it, but the problem is that I don't know how to do that dashed lines between the icons, also they want a little animation in the icons, so I assumed that each one should be a separate view, so far I've done this (it doesn't need to look exactly the same):
So, how could I draw that lines? Also if I could make that dashes to "run" acrross the lines would be awesome.
this is my xml:

Android - Bitmap - Fatal Signal 11 (SIGSEGV), code 1 - android
