for my case

my Toolbar is

 private void actionBarView(){


        toolbar = (Toolbar) findViewById(com.mafiree.salezstorm.R.id.toolbar);

        setSupportActionBar(toolbar);
        getSupportActionBar().setTitle("Tittle");

 /*       if(toolbar != null) {            setSupportActionBar(toolbar);            getSupportActionBar().setTitle("My custom toolbar!");            getSupportActionBar().setHomeButtonEnabled(true);            getSupportActionBar().setDisplayHomeAsUpEnabled(true);        }*/
        //back button action        ImageView imageview_back=(ImageView)toolbar.findViewById(com.mafiree.salezstorm.R.id.imageview_back);

        imageview_back.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                // Toast.makeText(getApplicationContext(),"back clicked",Toast.LENGTH_LONG).show();                finish();
            }
        });



        textview_property=(TextView)findViewById(R.id.textview_property_list);
      //  textview_property.setVisibility(View.GONE);
        textview_property.setOnClickListener(new OnClickListener() {
