The Home Activity
where the login button is
package com.example.james.assignment1_18094969;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View.OnClickListener;
import android.view.View;
import android.content.Intent;
public class Home extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
//findview for the login button
findViewById(R.id.button_login).setOnClickListener(new login());
}
onClickListener
for the login button to be clicked and take the user to the login page.
class login implements OnClickListener {
public void onClick(View v) {
Intent intent = new Intent(Home.this, login.class);
startActivity(intent);
}
}
}
The login screen:
package com.example.james.assignment1_18094969;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
public class Login extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
}
}
Try This and please Confirm Login Activity is declared in the manifest
package com.example.james.assignment1_18094969;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View.OnClickListener;
import android.view.View;
import android.content.Intent;
public class Home extends AppCompatActivity implements View.OnClickListener {
Button Login;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
Login=findViewById(R.id.button_login);
login.setOnClickListener(this);
}
@Override
public void onClick(View v) {
Intent intent = new Intent(Home.this, Login.class);
startActivity(intent);
}
}
this will be more correct approach to put click Listener's instead of defining inner class for click Listener. Or you can use functions instead.
public class Home extends AppCompatActivity {
Button loginButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
loginButton = (Button) findViewById(R.id.button_login);
loginButton.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
Intent intent = new Intent(Home.this, Login.class);
startActivity(intent);
}
});
}
Acitivity names should be used correctly.
Do this!
findViewById(R.id.button_login).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent = new Intent(Home.this, Login.class);
startActivity(intent);
}
}
