Android button not opening other class
0
I have problems with buttons.I have made 2 buttons that will when pressed open other activity(class).In code there is no error but when I launch emulator it just doesn't work and isn't opening those classes.
My button's btnopis and btnpronadi don't work(they are not opening other activity(class)).But I have button exit that Works and closes app. I don't get where the problem is. Here is the code
import android.content.Intent;
import android.os.Handler;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class MainActivity extends AppCompatActivity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
izlaz();
}
public Button btnopis;
public void otvoriopis(){
btnopis=(Button)findViewById(R.id.btnopis);
btnopis.setOnClickListener(new Button.OnClickListener() {
@Override
public void onClick(View v) {
Intent otvoriopis= new Intent(MainActivity.this,Opis.class);
startActivity(otvoriopis);
}
});
}
public Button btnpronadi;
public void otvoripronadi(){
btnpronadi=(Button)findViewById(R.id.btnpronadi);
btnpronadi.setOnClickListener(new Button.OnClickListener() {
@Override
public void onClick(View v) {
Intent otvoripronadi= new Intent(MainActivity.this,Pronadi.class);
startActivity(otvoripronadi);
}
});
}
public Button btnizlaz;
public void izlaz(){
btnizlaz=(Button)findViewById(R.id.btnizlaz);
btnizlaz.setOnClickListener(new Button.OnClickListener() {
@Override
public void onClick(View v) {
finish();
System.exit(0);
}
});
}
}
here is the manifest code:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.shromid">
<application
android:allowBackup="true"

You forgot do call otvoriopis() and otvoripronadi() at onCreate:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
izlaz();
otvoriopis();
otvoripronadi();
}
