Android image click in horizontal page view

Question

I've implemented horizontal page view with many images. And I'm trying to create a click event on the image.

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.pbase);
    ImageView binfo,bheacno;

    tvHeacno=(TextView) findViewById(R.id.tvheacno);
    heacno=getHeacno();
    tvHeacno.setText(heacno);

    MyPagerAdapter adapter=new MyPagerAdapter();
    ViewPager myPager=(ViewPager)findViewById(R.id.mythreepanelpager);
    myPager.setAdapter(adapter);
    myPager.setCurrentItem(0);

    binfo=(ImageView) findViewById(R.id.ivinfo);
    bheacno=(ImageView) findViewById(R.id.ivheacno);
    binfo.setOnClickListener(this);
    bheacno.setOnClickListener(this);

}

then i've MyPagerAdapter class and the onclik method. it returns null to binfo and hence fails at binfo.setOnClickListener(this) I've done image click before on normal pages successfully. Is it because of horizontal page views? How can I solve this issue??

Answer 1

binfo=(ImageView) findViewById(R.id.ivinfo);
bheacno=(ImageView) findViewById(R.id.ivheacno);
binfo.setOnClickListener(this);
bheacno.setOnClickListener(this);

the above code should be in the MyPagerAdapter class. The problem is solved. thanx guys for your help

Answer 2

try this. it may help you.

doneButton.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                                  Your code 
                                            }
                                   });

Answer 3

Share the layout xml, I think the error is at binfo declaration, might have some hierarchy.

binfo=(ImageView) findViewById(R.id.ivinfo);
