Start another activity by clicking a button
So heres my problem. I set up a button that when clicked should open a new
activity but when it is clicked I receive an error: Unfortunately
"app_name" has stopped working my logcat says :Fatal Exception Main
So heres my xml:
<?xml version="1.0" encoding="utf-8"?>

android:layout_alignBottom="@+id/textView7"
android:layout_alignLeft="@+id/button6"
android:text="Edit" />
</RelativeLayout>
and the second Xml to which im trying to reach in another activity:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="20dp"
android:textSize="40sp"
android:text="Monday" />
<EditText
android:id="@+id/editText1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/textView1"
android:layout_marginTop="36dp"
android:layout_toLeftOf="@+id/textView1"
android:ems="3"
android:inputType="time" />
<EditText
android:id="@+id/editText2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="@+id/editText1"
android:layout_alignBottom="@+id/editText1"
android:layout_centerHorizontal="true"
android:ems="3"
android:inputType="time" >
<requestFocus />
</EditText>
<Spinner
android:id="@+id/profileSelector"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="@+id/editText2"
android:layout_toRightOf="@+id/textView1"
android:ems="3"
android:prompt="@string/profile"
android:entries="@array/profileSelector"
/>
</RelativeLayout>
Finally the code that supports both:
package com.example.hush;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.widget.Button;
import android.view.View.OnClickListener;
public class MainActivity extends Activity {
Intent clickedDay;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainlayout);
Button mondayEdit=(Button)findViewById(R.id.button1);
}
public void mondayintent()
{
clickedDay= new Intent(this,Monday.class);
startActivity(clickedDay);}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is
present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
second activity code:
package com.example.hush;
import android.app.Activity;
import android.os.Bundle;
import android.widget.Button;
public class Monday extends Activity{
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.monday);
}
}
