Question

I’ve tried searching for many methods of utilizing multiple buttons on the same page. I can get the first button to work but the second and third buttons force-close. Does anyone have any idea why this may be? I think that it might be the syntax – but I could be wrong since I’m new to this. Thanks in advance.

Main Java:

package com.pangolin.rollin.ts;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class TeamSupport extends Activity {

    public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_team_support);
          Button wireless=(Button)findViewById(R.id.button_wireless);
          Button tools=(Button)findViewById(R.id.button_tools);
          Button about=(Button)findViewById(R.id.button_about);
          wireless.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                Intent myintent1 = new Intent(TeamSupport.this,Wireless.class);
                startActivity(myintent1);

            }
        });
          tools.setOnClickListener(new View.OnClickListener() {

                public void onClick(View v) {
                    Intent myintent2 = new Intent(TeamSupport.this,Tools.class);
                    startActivity(myintent2);

                }
            });
          about.setOnClickListener(new View.OnClickListener() {

              public void onClick(View v) {
                  Intent myintent3 = new Intent(TeamSupport.this,About.class);
                  startActivity(myintent3);
              }
          });
    }
}

Answer 1

You just implement OnClickListener.

now tools.setOnClickListener(this);

   @Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.R.id.button_wireless:
    Intent myintent1 = new Intent(TeamSupport.this,Wireless.class);
            startActivity(myintent1);
    break;

}

please try this is work better and occupy memory less.
