Issue
I am very new to android programming. I want to use a code that takes me to MainActivity from my current activity on a click of a Button.
Here is my current code:
package com.example.flashlightapp;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class Whitelight extends Activity implements OnClickListener {
Button b1 = (Button) findViewById(R.id.b3);
Intent i = new Intent(this, MainActivity.class);
{
this.startActivity(i);
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_whitelight);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
}
What should I put in
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
Solution
At first you must check if you declared all your activities in the manifest.xml file.
and in your Java code try this:
package com.example.flashlightapp;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class Whitelight extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_whitelight);
Button b1 = (Button) findViewById(R.id.b3);
b1.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(Whitelight.this, MainActivity.class);
this.startActivity(i);
}
});
}
}
