Я хотел использовать слайдер вступления для своего приложения. Я узнал об этом видеои увеличить 
где мойпроблема и что мне делать?
package time.one.just.show.introslyder;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.Html;
import android.widget.LinearLayout;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
private ViewPager mSlideViewPager;
private LinearLayout mDotsLayout;
private SlyderAdapter slyderAdapter;
//dots of any Slide pages
private TextView[] mDots;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mSlideViewPager = findViewById(R.id.viewPager);
mDotsLayout = findViewById(R.id.dots);
slyderAdapter = new SlyderAdapter(this);
mSlideViewPager.setAdapter(slyderAdapter);
addDotsIndiccator(0);
mSlideViewPager.addOnPageChangeListener(viewListener);
}
private void addDotsIndiccator(int position) {
mDots = new TextView[3];
for (int i = 0; i < mDots.length; i++) {
mDots[i] = new TextView(this);
mDots[i].setText(Html.fromHtml("•"));
mDots[i].setTextSize(35);
mDots[i].setTextColor(getResources().getColor(R.color.colorWhiteNearToGray));
mDotsLayout.addView(mDots[i]);
}
if (mDots.length > 0) {
mDots[position].setTextColor(getResources().getColor(R.color.colorWite));
}
}
ViewPager.OnPageChangeListener viewListener = new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int i, float v, int i1) {
}
@Override
public void onPageSelected(int i) {
addDotsIndiccator(i);
}
@Override
public void onPageScrollStateChanged(int i) {
}
};}
А это мой класс SideAdapter
package time.one.just.show.introslyder;
import android.content.Context;
import android.support.annotation.NonNull;
import android.support.v4.view.PagerAdapter;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.RelativeLayout;
import android.widget.TextView;
public class SlyderAdapter extends PagerAdapter {
Context context;
LayoutInflater layoutInflater;
public SlyderAdapter(Context context) {
this.context = context;
}
public int[] slide_imagesArray = {
R.drawable.eat,
R.drawable.men,
R.drawable.sleep};
public String[] slide_headerArray = {
"EAT", "men", "code"};
public String[] slide_descriptionArray = {
"this is 1st", "this is 2nd", "this is 3rd"
};
@Override
public int getCount() {
return slide_headerArray.length;
}
@Override
public boolean isViewFromObject(@NonNull View view, @NonNull Object o) {
return view == o;
}
@NonNull
@Override
public Object instantiateItem(@NonNull ViewGroup container, int position) {
layoutInflater = (LayoutInflater) context.getSystemService(context.LAYOUT_INFLATER_SERVICE);
View view = layoutInflater.inflate(R.layout.slide_layoout, container, false);
ImageView slideImageView = (ImageView) view.findViewById(R.id.slideImage);
TextView slideheader = (TextView) view.findViewById(R.id.slideheader);
TextView slidedescription = (TextView) view.findViewById(R.id.slideDescription);
slideImageView.setImageResource(slide_imagesArray[position]);
slideheader.setText(slide_headerArray[position]);
slidedescription.setText(slide_descriptionArray[position]);
container.addView(view);
return view;
}
@Override
public void destroyItem(@NonNull ViewGroup container, int position, @NonNull Object object) {
container.removeView((RelativeLayout) object);
}
}
, а это мой SliderLayout
