I have created a simple app which reads json data and displays all the results in a listview in my MainActivity.java
package com.test.rajat.minivie;

@Override

(SearchManager) getSystemService(Context.SEARCH_SERVICE);
searchView=
(SearchView) menu.findItem(R.id.action_search).getActionView();
searchView.setSearchableInfo(
searchManager.getSearchableInfo(getComponentName()));
searchView.setIconifiedByDefault(false);
final SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener() {

int id = item.getItemId();
switch(id)
{
case R.id.action_settings:

}
@Override

In OnItemClick() I'm starting another activity and adding the listitem data to it. But DetailsActivity.java is not generating the toast that i put in onCreate(). Any help?
DetailsActivity.java
package com.test.rajat.minivie;
import android.content.Intent;
import android.os.Bundle;
import android.os.PersistableBundle;
import android.support.v7.app.ActionBarActivity;
import android.util.Log;
import android.view.Menu;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
import com.squareup.picasso.Picasso;
import java.util.HashMap;
/**

*/
public class DetailsActivity extends ActionBarActivity {
private HashMap<String,String> movie_details;
private ImageView iv_poster_b;
private TextView tv_title_b;
@Override
public void onCreate(Bundle savedInstanceState, PersistableBundle persistentState) {
super.onCreate(savedInstanceState, persistentState);
setContentView(R.layout.activity_movie_details);
Intent intent=getIntent();
movie_details=(HashMap<String,String>) intent.getSerializableExtra("movie_details");
iv_poster_b=(ImageView) findViewById(R.id.iv_poster_b);
tv_title_b=(TextView) findViewById(R.id.tv_title_b);
Log.d("TAG","Created");
// This toast and function is not getting called //
Toast.makeText(this, "title", Toast.LENGTH_SHORT).show();
setDetails();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
private void setDetails(){
tv_title_b.setText(movie_details.get("title"));
Picasso.with(this).load("http://image.tmdb.org/t/p/w500"+movie_details.get("poster_path")).into(iv_poster_b);
}
}
I think you override wrong onCreate() method change it to
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
And please try to change
Toast.makeText(this, "title", Toast.LENGTH_SHORT).show();
with
Toast.makeText(DetailsActivity.this, "title", Toast.LENGTH_SHORT).show();
