#Override

super.onDrawerOpened(v);
}
};
drawer.addDrawerListener(actionBarDrawerToggle);
actionBarDrawerToggle.syncState();
}
}
I tested the same code yesterday and it worked. But now when I wanted to combine this code with another module it highlights the following line in red.
drawer.addDrawerListener(actionBarDrawerToggle);
When hover over it, it shows error
cannot resolve method addDrawerListener(android.support.v7.app.ActionBarDrawerToggle).

Application is unable to move to the DashboardAdminActivity/DashboardUserActivity while progressbar is showing & email and password validation is also working, but it's not going to the next activities according to the "usertype".
I also tried intent another way, but it's not working, if you guys can find any error/correction in my code, it would be appreciated.
My app keeps crashing when I try to log in (after LoginActivity file). Here's the code. I"d really appreciate some help with this.

I'm currently creating my own application with Android Studio. In this app, I want to create a switch, that changes to dark mode and back.
In the MainActivity.java I'm using the following code
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Switch;
import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.app.AppCompatDelegate;
public class MainActivity extends AppCompatActivity {
private Button button;
private Switch aSwitch;
public static final String MyPREFERENCES = "nightModePrefs";
public static final String KEY_ISNIGHTMODE = "isNightMode";
SharedPreferences sharedpreferences;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button feed = findViewById(R.id.feed);
sharedpreferences = getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);
aSwitch = findViewById(R.id.day_night);
checkNightModeActivated();
aSwitch.setOnCheckedChangeListener((buttonView, isChecked) -> {
if (isChecked) {
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES);
saveNightModeState(true);
recreate();
}else{
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO);
saveNightModeState(true);
recreate();
}
});
feed.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(MainActivity.this, Newsfeed.class));
}
});
}
private void saveNightModeState(boolean nightMode) {
SharedPreferences.Editor editor = sharedpreferences.edit();
editor.putBoolean(KEY_ISNIGHTMODE, nightMode);
editor.apply();
}
private void checkNightModeActivated() {
if(sharedpreferences.getBoolean(KEY_ISNIGHTMODE, false)) {
aSwitch.setChecked(true);
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES);
}else{
aSwitch.setChecked(false);
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO);
}
}
}
The problem is, that the switch will change the mode to dark when I've started the app. But then, the app beginns to flicker and does not longer responds.
Can soneone please tell me, what I'm doing wrong?
Kind regards
Kai
I've found a solution for my problem.
private Switch day_night;
day_night=findViewById(R.id.day_night);
day_night.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
getDelegate().setLocalNightMode(AppCompatDelegate.MODE_NIGHT_NO);
}
else {
getDelegate().setLocalNightMode(AppCompatDelegate.MODE_NIGHT_YES);
}
}
});
I would like my chronometer start when i click "ok" button from my Dialogbox... I can not.
I only succeed to start my chronometer when dialog box open. Then when i click "ok" button time has passed...
Thanks for your help... I begin to code.
My code:
import android.app.Activity;
import android.app.Dialog;
import android.os.Bundle;

import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class ActivityOne extends Activity implements OnClickListener {
private Chronometer myChronometer;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.timerlayout);
myChronometer = (Chronometer) findViewById(R.id.chronometer);
Button buttonStart = (Button) findViewById(R.id.startButton);
Button buttonStop = (Button) findViewById(R.id.pauseButton);
Button buttonReset = (Button) findViewById(R.id.resetButton);
buttonStart.setOnClickListener(this);
buttonStop.setOnClickListener(this);
buttonReset.setOnClickListener(this);
final Dialog dialog = new Dialog(ActivityOne.this, R.style.dialogchrono);
dialog.setContentView(R.layout.dialogchrono);
dialog.setTitle("Titre");
TextView txt = (TextView) dialog.findViewById(R.id.textView4);
TextView txt1 = (TextView) dialog.findViewById(R.id.textView1);
TextView txt2 = (TextView) dialog.findViewById(R.id.textView2);
TextView txt3 = (TextView) dialog.findViewById(R.id.textView3);
txt1.setText("Texte1");
txt2.setText("Texte2");
txt3.setText("Texte3");
txt.setText("Texte");
Button dismissButton = (Button) dialog.findViewById(R.id.button);
dismissButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.startButton:
myChronometer.start();
break;
case R.id.pauseButton:
myChronometer.stop();
break;
case R.id.resetButton:
myChronometer.setBase(SystemClock.elapsedRealtime());
break;
}
}
}
case R.id.startButton:
myChronometer.setBase(SystemClock.elapsedRealtime());
myChronometer.start();
break;
You need to reset the Chronometer
Chronometer start counting when activity open
