Unexpectedly changing widget in xamarin android - android

I have a xamarin forms app and a widget for Android platform in it.
The widget displays a calendar with highlited days according to the app's logic. It consists of a ListView filled with 7 TextViews text and color of which is made in-app. But I've encountered 2 annoying troubles:
trouble with sizing
During the development and launching the app on the emulator I made it look just like I wanted to. But when I deployed it on my personal device I've met with another result. I guess the trouble is in different desktop cell size on different devices. The code of all .xml files is given below.
widgetinfo.xml:
<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"
android:minWidth="145dp"
android:minHeight="110dp"
android:initialLayout="#layout/widget_layout"
android:resizeMode="horizontal"
android:updatePeriodMillis="1800000"/>
list_row.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/d1"
android:layout_width="31dp"
android:layout_height="29dp"
android:textAlignment="center"
android:background="#android:color/background_light"/>
<TextView
android:id="#+id/d2"
android:layout_width="31dp"
android:layout_height="29dp"
android:textAlignment="center"
android:background="#android:color/background_light"/>
<TextView
android:id="#+id/d3"
android:layout_width="31dp"
android:layout_height="29dp"
android:textAlignment="center"
android:background="#android:color/background_light"/>
<TextView
android:id="#+id/d4"
android:layout_width="31dp"
android:layout_height="29dp"
android:textAlignment="center"
android:background="#android:color/background_light"/>
<TextView
android:id="#+id/d5"
android:layout_width="31dp"
android:layout_height="29dp"
android:textAlignment="center"
android:background="#android:color/background_light"/>
<TextView
android:id="#+id/d6"
android:layout_width="31dp"
android:layout_height="29dp"
android:textAlignment="center"
android:background="#android:color/background_light"/>
<TextView
android:id="#+id/d7"
android:layout_width="31dp"
android:layout_height="29dp"
android:textAlignment="center"
android:background="#android:color/background_light"/>
</LinearLayout>
widget_layout.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#android:color/white">
<ListView
android:id="#+id/listViewWidget"
android:choiceMode="none"
android:clickable="false"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
So, the question - is there any way to make all the textviews look the same at all devices? I don't really need to change their size when resizing the widget, but such an option could also be really useful.
trouble with re-colouring.
when I press onto my widget (it always happens in random number of presses - sometimes it happens after the first one, sometimes - after about 20), or try to resize it, the colours go mad and change without any logic.
I was trying to add breakpoints into the ListProvider - they just don't react. I thought the trouble is with some intent coming while interacting the widget, but OnRecieve method doesn't react too. I just can't understand what makes the widget to change the colours. Codes are also below.

Justify text inside Android Textview

I want to Justify text inside Android TextView. With copy and share function and can accept spannable string. Can someone help me. It's so important for me. Thank you in advance

I have a solution for the text-justify in Android.
I have created a Custom Textview class, with this you can solve the justification issue in Android.
<com.trailcreator.util.JustifyCustomTextView
android:id="#+id/yourTextViewID"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
Here is the class
public class JustifyCustomTextView extends android.support.v7.widget.AppCompatTextView {
//Object that helps us to measure the words and characters like spaces.
private Paint mPaint;
//Thin space (Hair Space actually) character that will fill the spaces
private String mThinSpace = "\u200A";
//String that will storage the text with the inserted spaces
private String mJustifiedText = "";
//Float that represents the actual width of a sentence
private float mSentenceWidth = 0;
//Integer that counts the spaces needed to fill the line being processed
private int mWhiteSpacesNeeded = 0;
//Integer that counts the actual amount of words in the sentence

The method notifyDataSetChanged() not working in custom Listview

I custom listview with adapter extend BaseAdapter.
In method getView I have a button Add, and I set listener to it
item.btnAddBasket.setOnClickListener(new OnClickListener() {

But notifyDataSetChanged(); is not working in my code. Can you help me please?

Check all the view's background in an if statement in Android?

I have many buttons(81) from the left and right part of my layout. All in all, I have 162 buttons. I put those buttons to Button[] and I handle it properly.

Whenever I click on the button, just like in mine sweeper game, many buttons are randomly opened. And when it is opened, I am changing its background into R.drawable.affected. The goal of the game is to open all the buttons in left and right. My question is this, how can I check if all of the buttons are set in R.drawable.affected? Because after that, I will execute a method that will congratulate the user. Thanks in advance.
EDIT:
for (int i = 0; i < btn_right.length; i++) {
final int a = i;
int counter_total_affected = 0;
btn_right[i].setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (counter == 1) {
right_lung.add(a);
btn_right[a].setBackgroundResource(R.drawable.affected);
counter_total_affected++;
} else if (counter == 2) {
for (int i = 0; i < 2; i++) {
int n = i;
right_lung.add(a + n);
}
try {
for (int i = 0; i < 2; i++) {
int n = i;
btn_right[a + n].setBackgroundResource(R.drawable.affected);
counter_total_affected++;
}
} catch (Exception e) {
e.printStackTrace();
}
} else if (counter == 3) {
right_lung.add(a);
btn_right[a].setBackgroundResource(R.drawable.affected);
counter_total_affected++;
} else if (counter == 4) {
for (int i = 0; i < 25; i++) {
int n = i;
right_lung.add(a + n);
}
try {
for (int i = 0; i < 25; i++) {
int n = i;
btn_right[a + n].setBackgroundResource(R.drawable.affected);
counter_total_affected++;
}
} catch (Exception e) {
e.printStackTrace();
}
} else if (counter == ...) {
//statements...
} else if (counter_total_affected == (btn_left.length + btn_right.length)) {
//CONGRATULATORY METHOD
}
counter++;
}
}

Increment the counter each time you change background of button and compare its value with length of button array. if both are same that means, all button backgrounds are set.
Try this :
for (int i = 0; i < btn_right.length; i++) {
final int b = i;
btn_right[i].setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if btn_right[i].getDrawable().getConstantState().equals
(getResources().getDrawable(R.drawable.affected).getConstantState()))
{
if(counter == btn_right.length){
//Congratulate user...
}
}else{
btn_right[b].setBackgroundResource(R.drawable.affected);
counter++;
}
}
}

U can set Tag:
for (int i = 0; i < btn_right.length; i++) {
final int b = i;
btn_right[i].setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
if (counter == 1) {
right_affected.add(b);
btn_right[b].setBackgroundResource(R.drawable.affected);
btn_right[b].setTag('1');
} else {
//some stuff here...
}
}
}
after congratulate the user set its Tag to 0.
EDIT:
ArrayList<Integer> arrayofId =new ArrayList<Integer>();
#Override
public void onClick(View v) {
if (counter == 1) {
right_affected.add(b);
btn_right[b].setBackgroundResource(R.drawable.affected);
arrayofId.add(b);//need to convert int to Integer.
} else {
//some stuff here...
}
}
To congratulate:
for(int i=0;i<arrayofId.size();i++)
{
// you can get here id of effected buttons
}

How to keep track of item-checking in a custom ListView using a custom ArrayAdapter?

My stack is really overflow, I mean currently my brain can't think of a way to solve the below problem (Although I'm through trial-and-errors many days). All I want to do is a sreen for deletion purpose like (http://asset0.cbsistatic.com/cnwk.1d/i/tim/2010/11/18/Foreman_11654166_1073_com.probosoft.masscontactsdelete0_257x386.png)
I have a layout of a list-view-item like this (log_view.xml):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="5dp" >
<TextView
android:id="#+id/date_view"
android:gravity="top|left"
android:textStyle="bold"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true" />
<TextView
android:id="#+id/value_view"
android:gravity="top|left"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/date_view"
android:layout_alignParentLeft="true" />
<CheckBox
android:id="#+id/del_box"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="5dp"
android:visibility="gone"
android:focusable="false"
android:focusableInTouchMode="false" />
</RelativeLayout>
And this is my custom Adapter:

this.logList = data;
this.context = context;
checkList = new ArrayList<Boolean>();
for (int i = 0; i < logList.size(); i ++) {
checkList.add(false);
}
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
LogHolder logholder = null;
// Unidentified view
if(convertView == null) {
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
convertView = inflater.inflate(layoutResourceId, parent, false);
// Create a new holder
logholder = new LogHolder();
logholder.del_box = (CheckBox)convertView.findViewById(R.id.del_box);
logholder.del_box.setChecked(false);
final int iFinal = position;
logholder.del_box.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

}
});
logholder.date_view = (TextView)convertView.findViewById(R.id.date_view);
logholder.value_view = (TextView)convertView.findViewById(R.id.value_view);

}
// Identified view
else {
logholder = (LogHolder) convertView.getTag();
}
if (null != logList) {
if (null == checkList.get(position)) {
android.util.Log.e("getView", "Checklist null at " + position);
}
//logholder.del_box.setChecked((boolean)checkList.get(position));

}
android.util.Log.e("getView", " at " + position + ", value = " + logholder.value_view.getText().toString());
return convertView;

The problems are:
I can't keep track of the boolean values of each CheckBox. For example if I sort the logList (my database) then "notifyDataSetChanged" to the listView, but my checkList (which contains booleans of CheckBoxes) is still the same, and strange things happen. How can I apply EXACTLY all the sorting-operation of one list to another one? (IMO, "synchronized sorting" or something like that...)
As you can see, I've try to solve #1 by getting the del_box (my CheckBox id) from its row, then set its "OnCheckedChangeListener" to do the assigning (once checked, it will update relative value in the boolean List "checkList"). But strange things happen again:
When checked a row and scroll down, I see another one is (automatically) checked.
When scrolling back, the previous checked one... is unchecked (automatically, of course).
Maybe the Adapter is re-using the wrong Views/values but I have no clue of how to make it do things right... >"<
Your helps and guides are great. Sample codes of yours will be more than perfect to me... (I'm really exhausted right now >"<)
UPDATE:
I've find a way to (somehow) solve it, but maybe it's against API behavior of Android... If you have safer solution, plz let me know ^^
As mentioned in my second comment, here's the code:
#Override
public void onCheckedChanged(CompoundButton cb, boolean isChecked) {
int graphicalPos = -1;
// This is top view on the screen for sure
if (((View)cb.getParent()).getTop() < 0) {
graphicalPos = 0;
}
else if (((View)cb.getParent()).getTop() == 0) {
graphicalPos = (int) (((View)cb.getParent()).getTop() / ((View)cb.getParent()).getHeight());
}
else if (((View)cb.getParent()).getTop() > 0) {
graphicalPos = (int) (((View)cb.getParent()).getTop() / ((View)cb.getParent()).getHeight());
if (listView.getChildAt(0).getTop() < 0) {
graphicalPos = graphicalPos + 1;
}
else {
android.util.Log.e("NOT PLUS", "First Top = " + listView.getChildAt(0).getTop());
}
}
int dataPos = graphicalPos + listView.getFirstVisiblePosition();
lw_adapter.checkList.set(dataPos, isChecked);
android.util.Log.e("onCheckedChanged", "Checked row " + dataPos + ", graphicalPos = " + graphicalPos + ", top = " + ((View)cb.getParent()).getTop() + ", firstVisible = " + listView.getFirstVisiblePosition());
}

Application randomly stops responding.

I am new to programming and I'm making a very simple blackjack game with only basic functions. When I run the program on the emulator it runs maybe for one hand, two, sometimes 5 or more but it always stops responding at some stage when i click on one of the three butons. There is a splash screen that runs for three seconds and the there is a thread comming from that activity that starts this menu activity. Could anyone maybe tell why this is happening? It usually happens when I clcik on one of the buttons even though there is no much comput

Use the debugger in eclipse to find out where it gets frozen.
Also the android emulator is very slow even with a fast PC.

Try using the low resolution simulators.
open DDMS from the android-sdk\tools and check which method or thread is taking more time to execute.
Use AsyncTask or Handler when there is a functional(Computational) things running.
