Button doesn't open new activity

Question

I have a "inicio" activity with viewpager and have a button in one page inside of the viewpager , but when i click on it nothing happens.

I've tried every mode i found on internet cuz it nothing happens or "has stopped working"

I dont know what to do. It's simpliest thing ( open a activity ) but dont know why it dont works....

I think that maybe it is opened in background by the viewpager...

inicio . java

package com.example.vamaro.vamaroapp;

import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.LinearLayout;

import com.example.vamaro.vamaroapp.R;

public class inicio extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_inicio);
        ViewPager viewPager = (ViewPager)findViewById(R.id.iniciopagerp);
        viewPager.setAdapter(new inicioAdapter());

    }
    public class inicioAdapter extends PagerAdapter{
            LayoutInflater layoutInflater;
            int[] layouts={R.layout.inicioslide,R.layout.activity_casasslide,R.layout.deptoslide};
            @Override
    public int getCount(){
                return layouts.length;
            }
            @Override
    public boolean isViewFromObject(View view, Object object) {
           return (view==(LinearLayout)object);
            }
            @Override
    public Object instantiateItem(ViewGroup container,int position) {
                layoutInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                View vamaro1 = layoutInflater.inflate(R.layout.inicioslide, container,false);
                View vamaro2 = layoutInflater.inflate(R.layout.activity_casasslide, container,false);
                View vamaro3 = layoutInflater.inflate(R.layout.deptoslide, container,false);
                View viewarr[] = { vamaro1,vamaro2,vamaro3};
                container.addView(viewarr[position]);
                return viewarr[position];
            }
            @Override
            public void destroyItem(ViewGroup container,int position, Object object){
                container.removeView((LinearLayout)object);
            }

}
}

and the casasslider . java

package com.example.vamaro.vamaroapp;

import android.content.Context;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;

public class casasslide extends AppCompatActivity {
private Button btn;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_casasslide);
        btn = (Button) findViewById(R.id.butt);

        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                openActivityTotalC();
            }
        });
    }
    public void openActivityTotalC(){
        Intent i = new Intent(this, TotalCasas.class);
        casasslide.this.startActivity(i);
    }
}

Answer 1

you said your button is inside one of viewpager pages

but you've defined your button inside casasslide activity .

then where is the view pager page?

there should be a fragment in the viewPager that has the button . and the button should be defined there, not in the casasslide

Answer 2

That is alredy activity you don't need to write getactivity() or anything.

just this

Intent I = new Intent (this,Next.class);
startActivity(i);

if that working then debug your code and check onclick() called or not

happy coding!!!

Answer 3

Change from this

public void openActivityTotalC(){
    Intent i = new Intent(this, TotalCasas.class);
    casasslide.this.startActivity(i);
}

To this

public void openActivityTotalC(){
    Intent i = new Intent(this, TotalCasas.class);
    startActivity(i);
}

It should solve the problem. Otherwise you might need to post your Error log so other can help you to debug.
