How to detect the click event and the swipe event differently

[shawn peter]

i have an android app which contain view pager.I need to identify click event and the swipe event differently.I already overrides the onInterceptTouchEvent.

[Ulf Dittmer]

If this was my problem I'd leave onInterceptTouchEvent alone and handle different events with different listeners, in this case View.OnClickListener and ViewPager.OnPageChangeListener.

I have a viewpager with images.I need to do something when i click images.I implement the onclick listener for view

package com.horizontalscrollviewwithpageindicator;

import android.app.Activity;
import android.os.Bundle;
import android.support.v4.view.ViewPager;
import android.util.Log;
import android.view.Menu;
import android.view.View;

public class PageIndicatorActivity extends Activity {

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		try {
			setContentView(R.layout.activity_main);
			ViewPagerAdapter adapter = new ViewPagerAdapter(this, imageArra);
			//ViewPagerWithTapGestreDetection myPager = (ViewPagerWithTapGestreDetection) findViewById(R.id.myfivepanelpager);
			ViewPager myPager=(ViewPager)findViewById(R.id.myfivepanelpager);
			myPager.setAdapter(adapter);
			myPager.setCurrentItem(0);

			myPager.setOnClickListener(new View.OnClickListener() {
				public void onClick(View v) {
					// Perform action on click
					Log.e("PageIndicatorActivity PageIndicatorActivity", "PageIndicatorActivity");

				}
			});

		} catch (Exception e) {
			e.printStackTrace();
		}

	}

	private int imageArra[] = { R.drawable.antartica1, R.drawable.antartica2,
			R.drawable.antartica3, R.drawable.antartica4,
			R.drawable.antartica5, R.drawable.antartica6,
			R.drawable.antartica7, R.drawable.antartica8 };

	@Override
	public boolean onCreateOptionsMenu(Menu menu) {
		getMenuInflater().inflate(R.menu.activity_main, menu);
		return true;
	}

}

package com.horizontalscrollviewwithpageindicator;

import android.app.Activity;
import android.os.Parcelable;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
import android.view.View;
import android.view.ViewGroup.LayoutParams;
import android.widget.ImageView;
import android.widget.ImageView.ScaleType;

public class ViewPagerAdapter extends PagerAdapter {

	Activity activity;
	int imageArray[];

	public ViewPagerAdapter(Activity act, int[] imgArra) {
		imageArray = imgArra;
		activity = act;
	}

	public int getCount() {
		return imageArray.length;
	}

	public Object instantiateItem(View collection, int position) {
		ImageView view = new ImageView(activity);
		view.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
		view.setScaleType(ScaleType.FIT_XY);
		view.setBackgroundResource(imageArray[position]);
		((ViewPager) collection).addView(view, 0);
		
		return view;
	}

	@Override
	public void destroyItem(View arg0, int arg1, Object arg2) {
		((ViewPager) arg0).removeView((View) arg2);
	}

	@Override
	public boolean isViewFromObject(View arg0, Object arg1) {
		return arg0 == ((View) arg1);
	}

	@Override
	public Parcelable saveState() {
		return null;
	}
}

but the when i click on the image it doesn't work the onclick listener?

[Ulf Dittmer]

Why aren't you attaching the OnClickListener to the ImageView if it's clicks on the image that you're actually interested in?

[shawn peter]

public Object instantiateItem(View collection, int position) {
		ImageView view = new ImageView(activity);
		view.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
		view.setScaleType(ScaleType.FIT_XY);
		view.setBackgroundResource(imageArray[position]);
		((ViewPager) collection).addView(view, 0);
		
		view.setOnClickListener(new View.OnClickListener() {
			public void onClick(View v) {
				// Perform action on click
				Intent intent=new Intent(,PDFActivity.class);
				start
				Log.e("PageIndicatorActivity PageIndicatorActivity", "PageIndicatorActivity");

			}
		});
		
		return view;
	}

I need to call another activity when i click the image.But it is unable to call another activity inside this?

[Ulf Dittmer]

What does it matter what you do in a listener for where you attach it?

[shawn peter]

because i get the image in adapter,i added the onclickListener inside the adapter.but i am unable to call the another activity via intent.is there any other way to do this ulf ?

[shawn peter]

hi ulf ,i attached the listener to image.Is there any other way to do this ?

[Ulf Dittmer]

Why do you ask?

[shawn peter]

I need to call another activity when i click on the image.I have posted the my code above.But i am unable to call the activity via intent inside instantiateItem in adapter.Is there anything wrong in my code or any other place to call activity ?

[Ulf Dittmer]

because i get the image in adapter,i added the onclickListener inside the adapter.but i am unable to call the another activity via intent.is there any other way to do this ulf ?

This reasoning is fundamentally flawed. You assume because something you implemented didn't work it was the wrong way to implement it. Pardon me for being frank, but given the history of your Android development efforts as documented by your posts here, your first assumption should be that you made a mistake somewhere.

I need to call another activity when i click on the image.I have posted the my code above.But i am unable to call the activity via intent inside instantiateItem in adapter.Is there anything wrong in my code or any other place to call activity ?

What you posted doesn't even compile. If there are problems -as I've told you many times before, but unfortunately you insist on ignoring it, which is getting extremely tiresome- you need to tell us what you are doing, what you expected to happen in response, and what is actually happening. Post the values of all involved variables, the stack trace of all exceptions if there are any, etc. etc.

[shawn peter]

I know that is not compiling.I need to call another activity when i click the images.I am unable to call the activity inside the above call.Its not compiling.

public Object instantiateItem(View collection, int position) {  
        ImageView view = new ImageView(activity);  
        view.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));  
        view.setScaleType(ScaleType.FIT_XY);  
        view.setBackgroundResource(imageArray[position]);  
        ((ViewPager) collection).addView(view, 0);  
          
        view.setOnClickListener(new View.OnClickListener() {  
            public void onClick(View v) {  
                // Perform action on click  
               //I need to call the another activity i when i click the image .
  
            }  
        });  
          
        return view;  
    }  

[Ulf Dittmer]

Since you don't mention it, I assume that you agree now that the kind of listener is irrelevant?

As I said, if there are error messages, post them. This latest code doesn't even try to start to start an activity, so it is even less clear than before what "I am unable to call the activity" means.

[shawn peter]

ok ulf.If this is not the correct approach,what kind of approach is good.I found that using interface w can call activity method.Is it suit for this one?

[Ulf Dittmer]

I'm giving up, as this is getting too frustrating. You seem to be paying no attention whatsoever to what you are being told. Good luck.

[shawn peter]

I found the answer.We can use activity reference inside to call Intent.Below is the code

package com.sph.custom;


import com.sph.pdf.PDFActivity;

import android.app.Activity;
import android.content.Intent;
import android.os.Parcelable;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
import android.util.Log;
import android.view.View;
import android.view.ViewGroup.LayoutParams;
import android.widget.ImageView;
import android.widget.ImageView.ScaleType;

public class SectionAdapter extends PagerAdapter {

	Activity activity;
	int imageArray[];

	public SectionAdapter(Activity act, int[] imgArra) {
		imageArray = imgArra;
		activity = act;
	}

	public int getCount() {
		return imageArray.length;
	}

	public Object instantiateItem(View collection, int position) {
		ImageView view = new ImageView(activity);
		view.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
		view.setScaleType(ScaleType.FIT_XY);
		view.setBackgroundResource(imageArray[position]);
		((ViewPager) collection).addView(view, 0);
		
		view.setOnClickListener(new View.OnClickListener() {
			public void onClick(View v) {
				// Perform action on click
			
			 Intent i=new Intent(activity,ABCActivity.class);
			 activity.startActivity(i);
			
			}
		});
		
		return view;
	}

	@Override
	public void destroyItem(View arg0, int arg1, Object arg2) {
		((ViewPager) arg0).removeView((View) arg2);
	}

	@Override
	public boolean isViewFromObject(View arg0, Object arg1) {
		return arg0 == ((View) arg1);
	}

	@Override
	public Parcelable saveState() {
		return null;
	}
}
