Hello everybody i have a problem that when i click a button it remains as it is instead of starting new activity. I searched he problem in this site and found some solutions but none of them worked for me so i am writing my problem here.
the xml layout is
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/profile_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/profile" />
<Button
android:id="@+id/create_profile"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="@string/create_profile" />
<Button
android:id="@+id/edit_profile"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_toRightOf="@id/create_profile"
android:text="@string/edit_profile" />
<Button
android:id="@+id/delete_profile"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_toRightOf="@id/edit_profile"
android:text="@string/delete_profile" />
<Button
android:id="@+id/activate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_toRightOf="@id/delete_profile"
android:text="@string/activate" />
<ListView
android:id="@id/android:list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="@id/create_profile"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_below="@id/profile_title" />
<TextView
android:id="@id/android:empty"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="@id/create_profile"
android:layout_below="@id/profile_title"
android:gravity="center_vertical|center_horizontal"
android:text="@string/no_profiles" />
</RelativeLayout>
and the activity is
package com.android.SmartSwitch;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class Profile_Manager extends Activity {
private Button createButton;
private Button editButton;
private Button deleteButton;
private Button activateButton;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.profile);
setUpViews();
}
private void setUpViews() {
createButton = (Button)findViewById(R.id.create_profile);
editButton = (Button)findViewById(R.id.edit_profile);
deleteButton = (Button)findViewById(R.id.delete_profile);
activateButton = (Button)findViewById(R.id.activate);
createButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent intent = new Intent(Profile_Manager.this, Add_Profile.class);
startActivity(intent);
}
});
editButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
}
});
deleteButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
}
});
activateButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
}
});
}
}

When i click createButton, it doesn’t respond
As your Main Activity i.e., Profile_Manager consists of the following Code:
You have to note if the Profile Manager class is the class which will be launched i.e., if Profile_Manager Class is the First Screen then, you should create the above code in AndroidManifest.xml with the only change as android:name=”.Profile_Manager” instead of “SmartSwitchActivity” with the code additionally added for Add_Profile class as follows
I suppose by doing this changes,things will work fine.
If you are not able to understand the above working then,Here is the Link with Perfect Working Example and with available Source Code-Correct Working of Button Click
