Passing data between activities for a voting app

I am new to android programming and have ran into a problem. I am trying to create a voting app where when a user opens up the application and the MainActivity is shown, from here they press a button to go into the second Screen (Screen2) which shows images of people and their names as buttons. When a persons name (in a button on Screen2) is pressed , a text field shows the number of times the button is pressed in an another activity (Screen4) . The problem here is that when i try to show this (Screen4), the app crashes. I am quite new to this so if you didn't understand my issue or need more information please let me know. Any help is appreciated. Thank you.
EDIT : After some help I used Intent to try send the data across but now when when the button in screen2 is pressed the app refreshes and then takes me back to the mainActivity and when this process is tried again the app crashes.
This is the new Screen2 :
package com.example.myapplication1;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
public class Screen2 extends AppCompatActivity {
TextView showValue;
int counter = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_screen2);
showValue = findViewById(R.id.VoteCountAnnie);//VoteCountAnnie is the On click for the Textview in a different activity.
}
public void AnCount(View v) {
//increase the count
counter++;
showValue.setText(Integer.toString(counter));
}
public void ButtonToGoToTheOtherActivity(View v) {
Intent intent = new Intent(this, Screen4.class);
intent.putExtra("valueOfCounter", counter); //the code for sending data to the other activity.
startActivity(intent);
}
}
This is the XML for screen 2 :
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"

This is my Screen4:

setContentView(R.layout.activity_screen4);
Button3 = (Button) findViewById(R.id.Button3);
Button3.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) { openActivity4();
}
}
);
counter = getIntent().getIntExtra("valueOfCounter", 0); // 0 is default value
}
public void openActivity4() {
Intent intent = new Intent(Screen4.this, MainActivity.class);
startActivity(intent);

This is my main Activity Screen (not used for the clicking but if there is something wrong in this that could affect the other Screens please let me know) :
package com.example.myapplication1;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;

public class MainActivity extends AppCompatActivity {
private Button button;
private Button button2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
openActivity2();
}
});
button2 = (Button) findViewById(R.id.button2);
button2.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
openActivity3();
}
}
);
}
public void openActivity2() {
Intent intent = new Intent(this, Screen2.class);
startActivity(intent);

As Mike M. said you are using id of a textview which is in a different activity. In android we cannot access ids of views in a different activity. We can only access ids of view in the same activity in which we are.
So that is for the error you are getting.
For accessing Data from another activity you can pass the data like this:
public class Screen2 extends AppCompatActivity {
int counter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_screen1);
showValue = (TextView) findViewById(R.id.VoteCountAnnie);//VoteCountAnnie is the Id for the Textview in a different activity.
}
public void AnnieCountInc (View view) {
//increase the count
counter++;
showValue.setText(Integer.toString(counter));
}
//make another button with a method like
public void ButtonToGoToTheOtherActivity(View view){
Intent intent =new Intent(this,Screen4.class);
intent.putExtra("valueOfCounter",counter); //the code for sending data to the other activity.
startActivity(intent);
}
Then in your Screen4 activity you can get the value of "counter" in the onCreate method by:
counter = getIntent().getIntExtra("valueOfCounter",0); // 0 is default value
This is one method.
You can also use a static variable to pass on data easily by defining your counter varaible as
public static int counter;
Then you can access it directly and it will show you the value.

Android app stopped making call [duplicate]

This question already has an answer here:
No activity found to handle intent action.dial

Closed 5 years ago.
Here is main activity.
import android.content.Intent;

Intent intent;
intent = new Intent(Intent.ACTION_DIAL);
intent = intent.setData(Uri.parse("number:"+number.getText().toString()));
startActivity(intent);
}
});
}
}
I added this permission request to manifest file.
<uses-permission android:name="android.permission.CALL_PHONE"/>
Here is my XML file
<?xml version="1.0" encoding="utf-8"?>

I am this getting error when I press the call button to make call.
FATAL EXCEPTION: main

android.content.ActivityNotFoundException: No Activity found to handle

Error line is : startActivity(intent);

private void call() {
makecall.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
PackageManager pm = getPackageManager();
if (pm.hasSystemFeature(PackageManager.FEATURE_TELEPHONY)) {
if (!number.contains("tel:"))
number = "tel:" + number;
Uri link = Uri.parse(number);
Intent callIntent = new Intent(Intent.ACTION_DIAL, link);
startActivity(callIntent);
}else{
Toast.makeText(this,"No call facility available in device!",Toast.LENGTH_SHORT).show();
}
});
}
Now skip all crashes.

Please look into this
private void call() {
makecall.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent;
intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:"+number.getText().toString()));
startActivity(intent);
}
});
}

How to get time for splashscreen

How to get time for splashcreen?
I want to add about 15 second time? How can I integrate it into the code?
For example, to direct activity after about 15 seconds.
package com.trees.activities;
import android.app.Activity;
import android.content.Intent;
import android.content.SharedPreferences;
import android.os.Bundle;
public class MainSlider extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
SharedPreferences settings=getSharedPreferences("prefs",0);
boolean firstRun=settings.getBoolean("firstRun",false);
if(firstRun==false)//if running for first time
//Splash will load for first time
{
SharedPreferences.Editor editor=settings.edit();
editor.putBoolean("firstRun",true);
editor.commit();
Intent i=new Intent(MainSlider.this,MaterialIntro.class);
startActivity(i);
finish();
}
else
{
Intent a=new Intent(MainSlider.this,MainActivity.class);
startActivity(a);
finish();
}
}
}

HOW TO: Simple spash screen
First you need to define the spash screen in your layout.xml file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView android:id="#+id/splashscreen" android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:src="#drawable/splash"
android:layout_gravity="center"/>
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Hello World, splash"/>
</LinearLayout>
And your activity:
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
public class Splash extends Activity {
/** Duration of wait **/
private final int SPLASH_DISPLAY_LENGTH = 1000;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.splashscreen);
/* New Handler to start the Menu-Activity
* and close this Splash-Screen after some seconds.*/
new Handler().postDelayed(new Runnable(){
#Override
public void run() {
/* Create an Intent that will start the Menu-Activity. */
Intent mainIntent = new Intent(Splash.this,Menu.class);
Splash.this.startActivity(mainIntent);
Splash.this.finish();
}
}, SPLASH_DISPLAY_LENGTH);
}
}

Android dynamic listview

I want to make a ListView that gets its elements(strings) from user input. I have a button that directs the user to another activity and while in it, the user enters a name and presses another button to come back to the original activity. The same button gets and adds a string to the ArrayAdapter that the ListView uses and displays it as an element in the ListView. It doesn't seem to work and I know it's a stupid mistake, but I'm fresh to android development and this in particular I haven't done before.
Here's all the code:
the MainActivity
import android.content.Intent;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListAdapter;
import android.widget.ListView;
import java.util.ArrayList;
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ArrayList<String> simpleArray =new ArrayList<String>();
ListAdapter simpleAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,
simpleArray);
ListView lv = (ListView) findViewById(R.id.lv);
lv.setAdapter(simpleAdapter);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
public void enterActivity(View view) {
Intent toEnterSecond = new Intent(this, SecondActivity.class);
startActivity(toEnterSecond);
}
}
The second acitivity
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.EditText;
import java.util.ArrayList;
public class SecondActivity extends Activity{
private EditText projectName;
ArrayList simpleArray;
ArrayAdapter simpleAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.second);
projectName = (EditText) findViewById(R.id.eTxt);
}
public void getBack(View view) {
String projectCalling = String.valueOf(projectName.getText());
simpleArray.add(projectCalling);
simpleAdapter.notifyDataSetChanged();
Intent comeBack = new Intent(this, MainActivity.class);
startActivity(comeBack);
}
}
And the layouts
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<Button
android:layout_width="match_parent"
android:layout_height="80dp"
android:id="#+id/simpleButton"
android:text="click me plox"
android:onClick="enterActivity"/>
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/simpleButton"
android:id="#+id/lv">
</ListView>
</RelativeLayout>
//
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="20dp"
android:text="Enter the name of your project:"
android:id="#+id/txt"/>
<EditText
android:layout_width="200dp"
android:layout_height="40dp"
android:layout_below="#+id/txt"
android:id="#+id/eTxt"/>
<Button
android:layout_width="100dp"
android:layout_height="60dp"
android:layout_below="#+id/eTxt"
android:text="click"
android:onClick="getBack"/>
</RelativeLayout>

Explanation:
You can start SecondActivity with startActivityForResult() instead of startActivity as answered here and in onResultActivity method you can call simpleAdapter.notifyDataSetChanged();. Don't call simpleAdapter.notifyDataSetChanged(); in SecondActivity.
To learn how to use startActivityForResult check this.
Also use finish() instead of
Intent comeBack = new Intent(this, MainActivity.class);
startActivity(comeBack);
in SecondActivity to go back to MainActivity.
Solution:
Change MainActivity enterActivity method to this:
...
public void enterActivity(View view) {
Intent toEnterSecond = new Intent(this, SecondActivity.class);
startActivityForResult(toEnterSecond,1);
}
Add this to end of SecondActivity getBack method:
MainActivity.simpleArray.add(projectCalling);
Intent returnIntent = new Intent();
setResult(RESULT_OK,returnIntent);
finish();
Finally add this new method to MainActivity:
protected void onActivityResult(int requestCode, int resultCode, Intent data{
if (requestCode == 1) {
if(resultCode == RESULT_OK){
((ArrayAdapter) simpleAdapter).notifyDataSetChanged();
}
}
}
To be able to access simpleAdapter, you need to define it outside of onCreate:
public class MainActivity extends ActionBarActivity {
private ListAdapter simpleAdapter;
public static ArrayList<String> simpleArray;
#Override
protected void onCreate(Bundle savedInstanceState) {
...
simpleArray =new ArrayList<String>();
simpleAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,
simpleArray);
...
}

How can Add downloading status show (like as android defualt browser )

How can I show downloading status bar similar to android default browser:

You really should search before post a question here my friend.
There is a component in Android API that could help you called DownloadManager.
The Android DownloadManager introduced in Android 2.3. (API 9) is a system service which allows to handle long-running HTTP downloads in the background and notify the triggering application via a broadcast receiver once the download is finished.
Here is a little example for using the DownloadManager. The project will be called “de.vogella.android.downloadmanager” with the activity “DownloadManagerActivity” based on Android API9 or higher.
Change “main.xml” to the following.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<Button android:text="Start Download" android:id="#+id/button1"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:onClick="onClick"></Button>
<Button android:text="View Downloads" android:id="#+id/button2"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:onClick="showDownload"></Button>
<ImageView android:layout_height="wrap_content" android:id="#+id/imageView1"
android:src="#drawable/icon" android:layout_width="wrap_content"></ImageView>
</LinearLayout>
Change the code of your activity to the following.
package de.vogella.android.downloadmanager;
import android.app.Activity;
import android.app.DownloadManager;
import android.app.DownloadManager.Query;
import android.app.DownloadManager.Request;
import android.content.BroadcastReceiver;
