Inside my class I have timer which counts from 5 sec to 0 sec. I want to start new activity when counting ends. The problem is I dont know which context to put as argument in function.
Here is the code:
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.os.CountDownTimer;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.TextView;
public class PlayGameActivity extends Activity {
private Intent i;
private Game igra;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_play_game);
}
new CountDownTimer(5000, 1000) {
TextView mTextField = (TextView)findViewById(R.id.textView6);
public void onTick(long millisUntilFinished) {
mTextField.setText("" + millisUntilFinished / 1000);
}
public void onFinish() {
mTextField.setText("Gotovo!");
//here is the problem!
Intent intent = new Intent( getBaseContext() , TableActivity.class);
startActivity(intent);
}
}.start();
}
You should pass PlayGameActivity.this:
Intent intent = new Intent( PlayGameActivity.this , TableActivity.class);

The app stops working when clicking on the first item on the list! I tried writing the code in a couple of different ways but it still won't work! What am I doing wrong??
package com.vogella.android.filmapp;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ListAdapter;
import android.widget.ListView;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String [] filmArray = {"Harry Potter", "No time to die", "Finding Dory", "Spider-Man",
"The Avengers", "Little Women", "Dune"};
ListAdapter theAdapter = new MyAdapter(this,filmArray);
ListView film_list_view= findViewById(R.id.film_list_view);
film_list_view.setAdapter(theAdapter);
film_list_view.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (position==0){
Intent intent = new Intent(view.getContext(), HarryPotter.class);
startActivity(intent);
}
}
});
}
}
Help?
I want to move to another Activity after 5 seconds.
(Step4Activity -> WeightActivity)
I found this code, and it worked.
new Handler().postDelayed(new Runnable()
{
#Override
public void run()
{
Intent intent = new Intent(Step4Activity.this, WeightActivity.class);
startActivity(intent);
}
}, 5000);
But I want to use a variable 'count' as a parameter 'delaymillis' like this, but it didn't work.
new Handler().postDelayed(new Runnable()
{
#Override
public void run()
{
Intent intent = new Intent(Step4Activity.this, WeightActivity.class);
startActivity(intent);
}
}, count * 1000); // int count = 5
Is there any way to use variable?
Here's my full code. (Step4Activity.java)
package com.example.starbucksook;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.LinearLayout;
import android.widget.TextView;
import androidx.appcompat.app.AppCompatActivity;
import java.util.Timer;
import java.util.TimerTask;
public class Step4Activity extends AppCompatActivity {
//TextView countdown_text;
//LinearLayout timeCountSettingLV, timeCountLV;
//TextView hourET, minuteET, secondET;
//TextView hourTV, minuteTV, secondTV, finishTV;
//Button startBtn;
//int hour, minute, second;
int count = 5;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_step4);
// Unrelated code skipped
/*Here is 'Handler-postDelayed' method.*/
new Handler().postDelayed(new Runnable()
{
#Override
public void run()
{
Intent intent = new Intent(Step4Activity.this, WeightActivity.class);
startActivity(intent);
}
}, count * 1000);
}
I have the code for the sound and the next activity. I do not know how to merge the two codes in order to execute them at the same time or in sequence.
package com.example.testmessages;

import android.media.MediaPlayer;
import android.os.Bundle;
import android.util.Log;
import android.view.View;

import android.widget.EditText;
import android.widget.ImageButton;
public class MainActivity extends AppCompatActivity {
ImageButton imageButton;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Add sound
final MediaPlayer gunSoundMP = MediaPlayer.create(this, R.raw.gunsound);
ImageButton GunSound=(ImageButton)this.findViewById(R.id.imageButton3);
GunSound.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
gunSoundMP.start();
}
});
//Image button to execute new Activity
imageButton=(ImageButton) findViewById(R.id.imageButton3);
imageButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intentLoadMain2Activity = new Intent(MainActivity.this, Main2Activity.class);
startActivity(intentLoadMain2Activity);
gunSoundMP.start();
}
});
}
}

On screen 1, capture the value in onActivityResult() method, similarly as in screen 2.
I have an application that displays a splash screen then a 'Showonce' screen, I have used app prefs and a boolean "user_accept" to decide wether the screen gets displayed or not, trouble no matter if the boolean = true it still shows the page, please see my code for the pages, any help greatly appreciated :).

setContentView(R.layout.splash_layout);
final SharedPreferences settings = getSharedPreferences("APP_PREFS",
MODE_PRIVATE);
final boolean hasAgreed = settings.getBoolean("user_accepted", false);
Handler handler = new Handler();
// run a thread after 2 seconds to start the home screen
handler.postDelayed(new Runnable() {
#Override
public void run() {
if (hasAgreed == false){
Intent intent = new Intent(SplashScreen.this, ShowOnce.class);
SplashScreen.this.startActivity(intent);
Toast.makeText(getApplicationContext(), "DEBUG: USER HAS NOT ACCEPTED",Toast.LENGTH_LONG).show();
}else if (hasAgreed == true){
Toast.makeText(getApplicationContext(), "DEBUG: USER HAS ACCEPTED",Toast.LENGTH_LONG).show();
Intent intent = new Intent(getApplicationContext(), MainActivity.class);
startActivity(intent);
finish();
}
finish();
}

finish();
}
}
}
you are saving user_accept and checking for user_accepted
Please use public static final String to avoid such problems:
public static final String USER_ACCEPTED = "accepted";
.........
prefEditor.putBoolean(USER_ACCEPTED , true);
.........
settings.getBoolean(USER_ACCEPTED , false);
