I have custom dialog to show which has instruction about how to use the app.I am using ViewPager for this inside my custom dialog layout. I am getting error java.lang.IllegalArgumentException: No view found for id for fragment FragmentForInstruction1.
I have created a method which is called in onCreate(Bundle savedInstanceState) {} method .The method inflates the layout for dialog.
private void showCustomDialogForInstruction() {
final Dialog dialog = new Dialog(MainActivity.this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View dialogLayout = inflater.inflate(R.layout.dialog_layout_for_instruction_message, null, false);
layout.setAlpha(0.2f);
dialog.setCanceledOnTouchOutside(false);
dialog.setContentView(dialogLayout);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(0));
ViewPager viewPager=(ViewPager) dialog.findViewById(R.id.pagerInstruction);
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFrag(new FragmentForInstruction1());
adapter.addFrag(new Fragme`enter code here`ntForWelcomePage2());
adapter.addFrag(new FragmentForWelcomePage3());
adapter.addFrag(new FragmentForWelcomePage4());
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new OnPageChangeListener()
{
@Override
public void onPageSelected(int pos)
{
}
@Override
public void onPageScrolled(int pos, float arg1, int arg2)
{
}
@Override
public void onPageScrollStateChanged(int arg0)
{
}
});
Button done = (Button) dialog.findViewById(R.id.done);
done.setText("Got It");
done.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
}
});
Button neverShow = (Button) dialog.findViewById(R.id.nevershow);
neverShow.setText("Never Show Again");
neverShow.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
}
});
dialog.setOnKeyListener(new DialogInterface.OnKeyListener() {
@Override
public boolean onKey(DialogInterface dialog, int keyCode,
KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
return true;
}
return false;
}
});
dialog.getWindow().setBackgroundDrawable(
new ColorDrawable(android.graphics.Color.TRANSPARENT));
dialog.show();
}
my view pager class:
public class ViewPagerAdapter extends FragmentPagerAdapter
{
private final List<Fragment> mFragmentList = new ArrayList<Fragment>();
public ViewPagerAdapter(FragmentManager manager)
{
super(manager);
}
@Override
public Fragment getItem(int position)
{
return mFragmentList.get(position);
}
@Override
public int getCount()
{
return mFragmentList.size();
}
public void addFrag(Fragment fragment)
{
mFragmentList.add(fragment);
}
}
and i call the method in MainActivity :
public class MainActivity extends AppCompatActivity {
SharedPreferences sharedPreferencesNeverShowAgain ;
boolean neverShowAgain;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sharedPreferencesNeverShowAgain = PreferenceManager.getDefaultSharedPreferences(this);
neverShowAgain = sharedPreferencesNeverShowAgain.getBoolean("NeverShowAgain", false);
if(!neverShowAgain){
showCustomDialogForMessage();
}
}
}
