How do i modify data on my MainActivity from Settings Activity? - java

I've tried many other threads and articles but I just can't find the right stuff that I am looking for.
So I have a MainActivity and a SettingsActivity both are java classes. In my main activity there is a button when pressed, increases the count by +1, and shows it on a TextView, it also makes the device vibrate on every increment/Every button press. I want to make a switchpreference in SettingsActivity which if kept off/false, turns off the vibration on button press and if kept on/true, turns on the vibration on button press.
I don't know how to retrieve the state of SwitchPreferenceCompat(ON OR OFF) from SettingsActivity and use it in the MainActivity, so if the user turns the switch off in setting activity, the vibration should stop on button press which is in MainActivity.
I have already used Shared Preferences in MainActivity for saving the current count/number when App is closed and resumes from the same count when reopened.

I did try some stuff by myself in here but it crashed my app.

.replace(R.id.settings, new SettingsFragment())

ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setDisplayHomeAsUpEnabled(true);
}
}
public static class SettingsFragment extends PreferenceFragmentCompat {
#Override
public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
setPreferencesFromResource(R.xml.root_preferences, rootKey);
}
}
}
root_preference.xml
<PreferenceScreen xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory app:title="Settings"
app:iconSpaceReserved="false">
<SwitchPreferenceCompat
app:key="Switchsett1"
app:title="Vibration"
app:summaryOff="Turn Vibration On"
app:summaryOn="Turn Vibration Off"
app:iconSpaceReserved="false"
app:defaultValue="true"
/>
<SwitchPreferenceCompat
app:key="Switchset2"
app:iconSpaceReserved="false"
app:summaryOff="#string/attachment_summary_off"
app:summaryOn="#string/attachment_summary_on"
app:title="#string/attachment_title" />
</PreferenceCategory>
</PreferenceScreen>

I don't know how to retrieve the state of switch(ON OR OFF) from SettingsActivity
To get the value of SwitchPreferenceCompat from shared preference, then you need to retrieve it as a Boolean
Now the key of your first SwitchPreferenceCompat is Switchsett1, so to retrieve the value of this:
public class MainActivity extends AppCompatActivity {
Boolean switchPref;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
....
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);
switchPref = prefs.getBoolean("Switchsett1", false);
Toast.makeText(this, String.valueOf(switchPref), Toast.LENGTH_SHORT).show(); // shows true if the SwitchPreferenceCompat is ON, and false if OFF.
Now the Toast in the above script shows true if the SwitchPreferenceCompat is ON, and false if it's OFF.
You can do the same for Switchset2 SwitchPreferenceCompat

SharedPreferences not save boolean value when restart app

I am developing an app that I use in DarkMode theme that I put a Switch to on and off darkMode and I save it inside a boolian whitch means darkMode get true or false (boolean isDarkMode =false;)
it work well and I use SharedPreferences to save this true or false value to use it in another activitys .
it work but ...
when I close app and run app again the value of SharedPreferences is not saved and it goes back to first value of boolian
(thank u)

private void getData() {
SharedPreferences sharedPreferences = getSharedPreferences(DARKMODE, MODE_PRIVATE);
isDarkMode = sharedPreferences.getBoolean("ISDARKMODE", false);
}
}
In your checkedChangedListener you set darkMode to true and false respectively.
And in your myboolian method is the only place where your write the variable.
This method is only called from your onCreate and nowhere else. In addition to that, this method always sets darkMode = !darkMode, swapping the value.
You have to call myboolian in the onCheckedChanged and remove the darkMode = !darkMode or you will always reset to the value before.

I also have an API in php :

$connect->set_charset('utf8');
if(isset($_GET['cat_id']))
{
$query = "SELECT * FROM tbl_news_category c,tbl_news n WHERE c.cid=n.cat_id and c.cid='".$_GET['cat_id']."' ORDER BY n.news_heading ASC";
$resouter = mysqli_query($connect, $query);
}
else if(isset($_GET['nid']))
{
$id = $_GET['nid'];
$query = "SELECT * FROM tbl_news_category c,tbl_news n WHERE c.cid = n.cat_id && n.nid = '$id'";
$resouter = mysqli_query($connect, $query);
}
else if(isset($_GET['latest_news']))
{
$limit = $_GET['latest_news'];
$query = "SELECT * FROM tbl_news_category c,tbl_news n WHERE c.cid=n.cat_id ORDER BY n.news_heading ASC";
$resouter = mysqli_query($connect, $query);
}
else
{
$query = "SELECT * FROM tbl_news_category ORDER BY cid DESC";
$resouter = mysqli_query($connect, $query);
}
$set = array();
$total_records = mysqli_num_rows($resouter);
if($total_records >= 1){
while ($link = mysqli_fetch_array($resouter, MYSQLI_ASSOC)){
$set['NewsApp'][] = $link;
}
}
echo $val= str_replace('\\/', '/', json_encode($set));
?>
My problem is on the "else if(isset($_GET['latest_news']))"
Thanks for help
did you try the EndlessRecyclerOnScrollListener ?
You can found it here : https://gist.github.com/ssinss/e06f12ef66c51252563e
This way you could implement paging and you will not load all your stuff the first time you launch your activity.
You have to define a Step. It will be the number of items you will load per page. You will define it, backend (php API) and frontend (Android App).
Backend
You have to add a new parameter on your php API like this :
isset($_GET['page'])
Then your SQL query will look like this :
$page = $_GET['page'];
$step = 5;
$query = "SELECT * FROM tbl_news_category c,tbl_news n WHERE c.cid=n.cat_id and c.cid='".$_GET['cat_id']."' ORDER BY n.news_heading ASC LIMIT ".(($page - 1) * $step) . "," . $step;
Android App
Get the EndlessRecyclerOnScollListener.
Add a private int current_page to your class.
Add a Scroll Listener on your RecyclerView like this :
mRecyclerView.addOnScrollListener(new EndlessRecyclerOnScrollListener(
new LinearLayoutManager(getActivity())) {
#Override
public void onLoadMore() {
CallPhpApi(cat_id, current_page);
}
});
In the CallPhpApi, just call your php API with your new parameter page.
Get your objects from your request and add them to you arrayItemNewsList. Then notify your adapter that dataset changed by calling :
mAdapter.notifyDataSetChanged();
Hope it will help.

AdMob Interstitial not loading

I have a problem with admob ads.
The banner ad seems to work fine but the Interstitial is not loading.
I have tried various solutions, generating different ad unit id's and trying admob test ids.

The simplest answer is that mode is not equal to "qteday"
if(mode.equals("qteday")){
Unless that is true, the interstitial will never be loaded.

Android: why my onResume() DialogInterface keeps looping non stop?

May I ask why my onResume() DialogInterface keeps looping non stop? I have reference the onResume() from this website: http://pulse7.net/android/android-delete-sms-message-from-inbox-in-android/
#Override
protected void onResume() {
super.onResume(); int i=0;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) {
if(i==0) {
if (!Telephony.Sms.getDefaultSmsPackage(this).equals(myPackageName)) {
AlertDialog.Builder builder = new AlertDialog.Builder(ActivityMain_txt.this);
builder.setMessage("This app is not set as your default messaging app. Do you want to set it as default?")
.setCancelable(false)
.setTitle("Alert!")
.setNegativeButton("No", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
})
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
#TargetApi(19)
public void onClick(DialogInterface dialog, int id) {
Intent intent = new Intent(Telephony.Sms.Intents.ACTION_CHANGE_DEFAULT);
intent.putExtra(Telephony.Sms.Intents.EXTRA_PACKAGE_NAME, getPackageName());
startActivity(intent);
dialog.dismiss();
}
});
builder.show();
i++;}
}
}
But when I add this part of the code, the DialogInterface for "setPositiveButton" keeps looping non-stop. I am trying to set my application to become the default message application, so I will be able to delete messages. As now it is not set to become the default application, I am unable to delete any messages successfully. Any help will be deeply appreciated. Thanks in advance.

You are using the variable i as a flag, but whenever you open your app the value of i will be 0 again. You should store your flag in a persistent database. Either use SQLite to set i or use any other method like create a file when the user says yes to your question and then check if the file exists or not. If you don't understand what I've told you, I can send you some code snippets.
OK, I assume you are using i as a flag to check if user has set your app as default or not, so I suggest you to use SharedPreferences to store the value of i so that later on you can check the value of i in a better manner. Add the following code in your onResume function:
sharedpreferences = getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedpreferences.edit();
Instead of i++ use:
editor.putInt(i, 1);
editor.commit();
And to check if i==0 use:
int check =sharedprferences.getInt(i);
if(check == 0) {...........}

Android cannot be referenced from a static context

I'm a beginner on Android and this is the first I'm creating an app named GeoQuiz which basically has a few questions and the user has to click true/false or request the answer with the cheat button.I'm getting this one line of error related with a non-static an a static context in line 138,what am I doing wrong? I'm trying that every time i click on the button cheat, it open the other window that is under a different .xml file and in an another java class

this is the class for the cheat class and cheatButton
package com.example.fusion.geoquiz;
import android.app.Activity;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.widget.Button;
import android.widget.ImageButton;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;

/**

*/
public class cheatActivity extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_cheat);
}
}
Replace
Intent intent = new Intent(QuizActivity.this, cheatActivity.startActivity(intent));
with
Intent intent = new Intent(QuizActivity.this, cheatActivity.class);
startActivity(intent);
See the docs for more details..
Not sure what you're doing there, but you need to reference the other activity class. Simply calling startActivity is enough, because it will be implicitly called from QuizActivity.this.
Intent intent = new Intent(QuizActivity.this, cheatActivity.class);
startActivity(intent);
To save you from future errors choose one activity class that you will be using either Activity or ActionBarActivity. The latter is from the support package.
