Hey Good People,
Basically I have a Radio Group with two radio buttons, one of them is labelled RUN and the other is labelled PASS.
Just underneath this I also have a check-box labelled "Pass Complete"
Question: How do I disable the check-box when RUN radio button is selected (so it can't be selected) and enable it while the PASS radio button is selected?
Any help constructing some type of IF statement
XML
<RadioGroup
android:id="@+id/runandpass"

Now i also have a andoid activity_main.xml in the same folder which i added nothing to it. i also created a java file called Tabs.Java and put it in the src folder under src>com.example.qosmetre>Tabs.Java with the following code
package com.example.qosmetre;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class Tabs extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tabs);
}
}
Now my question is, when i run my app on the terminal or in debugging mode, how come nothing is showing up but a blank screen? Like i want the tabs to show up first thing with all the stuff underneath them as shown in the code above. Also how would i import a library for scatter plotting data that would be in my app?
I need to know where and what files to put what code in because im just a beginner and i dont know too much so ill need big guidence.
Thanks again in advance.
So, Im making a Root Checker app for android with Root Tools.

I have created an android program which contains listview. Emulator and my phone (Samsung Galaxy S) shows like;
-see First Attachment (1.png)
But when I open my program in Samsung Note 3, it shows like;
-see Second Attachment (2.png)
It likes 2 empty rows(empty but their colors dark blue) and 1 real list view item. 2 empty rows, 1 real item, 2 empty rows, 1 real item ....
I tried each of item in listview. I removed each one and it does not solve my problem. And some bigger screen phones have same issue. How can i solve it?

Introduction
In this article, we can learn how to get the number of Covid-19 affected cases world-wide as well as India wise. Here, we have used the Volley as Library to fetch the data using the REST API to display in the application. In this application, we can find the total cases affected, number of cases recovered and number of deaths on world wide as well as in India can find the state wise list also.
So, I will provide a series of articles on this Patient Tracking App, in upcoming articles I will integrate other Huawei Kits.
If you are new to this application, follow my previous articles.

https://forums.developer.huawei.com/forumPortal/en/topic/0201908355251870119
Requirements
1. Any operating system (MacOS, Linux and Windows).
2. Must have a Huawei phone with HMS 4.0.0.300 or later.
3. Must have a laptop or desktop with Android Studio, Jdk 1.8, SDK platform 26 and Gradle 4.6 and above installed.
4. Minimum API Level 24 is required.
5. Required EMUI 9.0.0 and later version devices.
How to integrate HMS Dependencies
1. First register as Huawei developer and complete identity verification in Huawei developers website, refer to register a Huawei ID.
2. Create a project in android studio, refer Creating an Android Studio Project.
3. Generate a SHA-256 certificate fingerprint.
4. To generate SHA-256 certificate fingerprint. On right-upper corner of android project click Gradle, choose Project Name > Tasks > android, and then click signingReport, as follows.
Note: Project Name depends on the user created name.
5. Create an App in AppGallery Connect.
6. Download the agconnect-services.json file from App information, copy and paste in android Project under app directory, as follows.
7. Enter SHA-256 certificate fingerprint and click Save button, as follows.
Note: Above steps from Step 1 to 7 is common for all Huawei Kits.
8. Add the below maven URL in build.gradle(Project) file under the repositories of buildscript, dependencies and allprojects, refer Add Configuration.
Java:
maven { url 'http://developer.huawei.com/repo/' }
classpath 'com.huawei.agconnect:agcp:1.6.0.300'
9. Add the below plugin and dependencies in build.gradle(Module) file.
Java:
apply plugin: id 'com.huawei.agconnect'
// Huawei AGC
implementation 'com.huawei.agconnect:agconnect-core:1.6.0.300'
// Recyclerview
implementation 'androidx.recyclerview:recyclerview:1.2.1'
// Volley Library
implementation 'com.android.volley:volley:1.2.1'
10. Now Sync the gradle.
11. Add the required permission to the AndroidManifest.xml file.
Java:
<uses-permission android:name="android.permission.INTERNET" />
Let us move to development
I have created a project on Android studio with empty activity let us start coding.
In the Home.kt activity to find the business logic for button item click.
Code:
class Home : AppCompatActivity(), HomeAdapter.ItemListener {
private lateinit var recyclerView: RecyclerView
private lateinit var arrayList: ArrayList<HomeIcons>
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_home)
recyclerView = findViewById(R.id.recyclerview_list)
arrayList = ArrayList()
arrayList.add(HomeIcons("Patient", "Add details", R.drawable.add_icon, "#00b0ff"))
arrayList.add(HomeIcons("Covid-19", "Covid Cases", R.drawable.covid_icon, "#00b0ff"))
val adapter = HomeAdapter(applicationContext, arrayList, this)
recyclerView.adapter = adapter
recyclerView.layoutManager = GridLayoutManager(this, 2)
recyclerView.setHasFixedSize(true)
}
override fun onItemClick(item: Int) {
when(item ) {
0 -> {val intent = Intent(this, PatientActivity::class.java)
startActivity(intent)
}
1 -> {val intent = Intent([email protected], CovidActivity::class.java)
startActivity(intent)
}
}
}
}
In the CovidActivity.kt activity to find the business logic for cases list data.
Java:
class CovidActivity : AppCompatActivity() {
lateinit var worldCases: TextView
lateinit var worldRecovered: TextView
lateinit var worldDeaths: TextView
lateinit var countryCases: TextView
lateinit var countryRecovered: TextView
lateinit var countryDeaths: TextView
lateinit var stateRV: RecyclerView
lateinit var stateRVAdapter: CasesAdapter
lateinit var stateList: List<CasesData>
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_covid)
worldCases = findViewById(R.id.txt_world_cases)
worldRecovered = findViewById(R.id.txt_world_recovered)
worldDeaths = findViewById(R.id.txt_world_deaths)
countryCases = findViewById(R.id.txt_india_cases)
countryRecovered = findViewById(R.id.txt_india_recovered)
countryDeaths = findViewById(R.id.txt_india_deaths)
stateRV = findViewById(R.id.recyclerview_cases)
stateList = ArrayList<CasesData>()
getStateInfo()
getWorldInfo()
}
private fun getStateInfo(){
val url = "https://api.rootnet.in/covid19-in/stats/latest"
val queue = Volley.newRequestQueue([email protected])
val request = JsonObjectRequest(Request.Method.GET,url, null, { response ->
try{
val dataObj = response.getJSONObject("data")
val summaryObj = dataObj.getJSONObject("summary")
val cases: Int = summaryObj.getInt("total")
val recovered:Int = summaryObj.getInt("discharged")
val deaths: Int = summaryObj.getInt("deaths")
countryCases.text = cases.toString()
countryRecovered.text = recovered.toString()
countryDeaths.text = deaths.toString()
val regionalArray = dataObj.getJSONArray("regional")
for(i in 0 until regionalArray.length()){
val regionalObj = regionalArray.getJSONObject(i)
val stateName: String = regionalObj.getString("loc")
val cases: Int = regionalObj.getInt("totalConfirmed")
val deaths: Int = regionalObj.getInt("deaths")
val recovered: Int = regionalObj.getInt("discharged")
val stateCases = CasesData(stateName,recovered,deaths,cases)
stateList = stateList+stateCases
}
stateRVAdapter = CasesAdapter(stateList)
stateRV.layoutManager = LinearLayoutManager(this)
stateRV.adapter = stateRVAdapter
}
catch (e:JSONException){
e.printStackTrace()
}
}, {error -> Toast.makeText(this, "Failed to get Data", Toast.LENGTH_SHORT).show()
}
)
queue.add(request)
}
private fun getWorldInfo(){
val url = "https://corona.lmao.ninja/v3/covid-19/all"
val queue = Volley.newRequestQueue([email protected])
val request = JsonObjectRequest(Request.Method.GET,url, null, { response ->
try{
val worldCases1: Int = response.getInt("cases")
val worldRecovered1:Int = response.getInt("recovered")
val worldDeaths1: Int = response.getInt("deaths")
worldRecovered.text = worldRecovered1.toString()
worldCases.text = worldCases1.toString()
worldDeaths.text = worldDeaths1.toString()
}
catch (e:JSONException){
e.printStackTrace()
}
}, {error ->
Toast.makeText(this, "Failed to get Data", Toast.LENGTH_SHORT).show()
}
)
queue.add(request)
}
}
Create a CasesData.kt data class to list the data variables.
Java:
data class CasesData(
val state: String,
val recovered: Int,
val deaths: Int,
val cases: Int
)
Create a CasesAdapter.kt adapter class to hold the list.
Java:
class CasesAdapter (private val stateList: List<CasesData>): RecyclerView.Adapter<CasesAdapter.ViewHolder>(){
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): CasesAdapter.ViewHolder {
val view: View = LayoutInflater.from(parent.context).inflate(R.layout.cases_list, parent, false)
return ViewHolder(view)
}
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
val stateData = stateList[position]
holder.stateCases.text = stateData.cases.toString()
holder.stateName.text = stateData.state.toString()
holder.stateDeaths.text = stateData.deaths.toString()
holder.stateRecovered.text = stateData.recovered.toString()
}
override fun getItemCount(): Int {
return stateList.size
}
inner class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
val stateName = itemView.findViewById<View>(R.id.txt_state) as TextView
val stateCases = itemView.findViewById<View>(R.id.txt_state_cases) as TextView
val stateDeaths = itemView.findViewById<View>(R.id.txt_state_deaths) as TextView
val stateRecovered = itemView.findViewById<View>(R.id.txt_state_recovered) as TextView
}
}
In the activity_home.xml we can create the UI screen for Recycler View item buttons.
Java:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/recyclerview_list"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</androidx.constraintlayout.widget.ConstraintLayout>
In the activity_covid.xml we can create the UI screen for cases list.
