I'm learning android developpement, and I wrote a short and easy code, but it doesn't work. I can't start another activity,despite many try ! Here is the code of the main activity :
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pageaccueil);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.pageaccueil, menu);
return true;
}
public void onCreate1(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_pageaccueil);
final Button button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Pageaccueil.this, Devise.class);
startActivity(intent);
}
});
}
}
And the button part of the XML Layout from the first/main activity :
<Button
android:id="@+id/button1"
style="?android:attr/buttonStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginTop="38dp"
android:text="convertisseur de devises"
/>
The second activity is "devise", and here is its code : import android.os.Bundle; import android.app.Activity; import android.view.Menu;
public class Devise extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_devise);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.devise, menu);
return true;
}
}
Does anyone know How can I make the second activity to launch ? I tried many times without any success .
Thank you in advance !!

use Following in your onCreate() instead of onCreate1()
final Button button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Pageaccueil.this, Devise.class);
startActivity(intent);
}
});
}
