In the below example I have created custom ViewPager in android. Here first I have added TextView and ViewPager in activity_main.xml and In MainActivity I have used MyPagerAdapter class and extends with the PagerAdapter class , In resource i have added five images pages and I have also used Toast function to get page position when you clicked on image. You can see below program it will clearly describe you How to make Custom ViewPager in android.
Srep(1)activity_main.xml layout-
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:orientation="vertical"
tools:context="com.example.androidviewpagerapp.MainActivity" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:autoLink="web"
android:textSize="20dp"
android:textColor="#eeec3e24"
android:text="Custom ViewPager"
android:textStyle="bold" />
<android.support.v4.view.ViewPager
android:id="@+id/myviewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
Srep(2)MainActivity-
public class MainActivity extends Activity {
ViewPager viewPager;
MyPagerAdapter myPagerAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
viewPager = (ViewPager)findViewById(R.id.myviewpager);
myPagerAdapter = new MyPagerAdapter();
viewPager.setAdapter(myPagerAdapter);
}
private class MyPagerAdapter extends PagerAdapter {
int NumberOfPages = 5;
int[] res = {
R.drawable.one,
R.drawable. two,
R.drawable.three,
R.drawable.four,
R.drawable.one};
int[] backgroundcolor = {
0xFF101010,
0xFF202020,
0xFF303030,
0xFF404040,
0xFF505050};
@Override
public int getCount() {
return NumberOfPages;
}
@Override
public boolean isViewFromObject(View view, Object object) {
return view == object;
}
@Override
public Object instantiateItem(ViewGroup container, int position) {
TextView textView = new TextView(MainActivity.this);
textView.setTextColor(Color.WHITE);
textView.setTextSize(30);
textView.setTypeface(Typeface.DEFAULT_BOLD);
textView.setText(String.valueOf(position));
ImageView imageView = new ImageView(MainActivity.this);
imageView.setImageResource(res[position]);
LinearLayout.LayoutParams imageParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
imageView.setLayoutParams(imageParams);
LinearLayout layout = new LinearLayout(MainActivity.this);
layout.setOrientation(LinearLayout.VERTICAL);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT);
layout.setBackgroundColor(backgroundcolor[position]);
layout.setLayoutParams(layoutParams);
layout.addView(textView);
layout.addView(imageView);
final int page = position;
layout.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
Toast.makeText(MainActivity.this,
"Page " + page + " clicked",
Toast.LENGTH_SHORT).show();
}});
container.addView(layout);
return layout;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView((LinearLayout)object);
}
}
}
