Question

String is working fine, what about double ?

Here is my code

ImageView protect_me_btn=(ImageView) findViewById(R.id.protect_me_btn);
protect_me_btn.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        pbupdate.setVisibility(4);
        String lat= Double.toString(latitude);
        Intent inte=new Intent(getApplicationContext(),set_alaram.class);
        Bundle lati=new Bundle();
        lati.putString("first",lat);
        inte.putExtras(lati);
        startActivity(inte);                    
    }
});

Answer 1

Send Double value using Bundle as to set_alaram Activity:

protect_me_btn.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            pbupdate.setVisibility(4);
            String lat= Double.toString(latitude);
            Intent inte=new Intent(getApplicationContext(), set_alaram.class);
            Bundle lati=new Bundle();
            lati.putString("first",lat);
            lati.putDouble("lat", latitude); //<< send double using putDouble
            inte.putExtras(lati);
            startActivity(inte);                    
        }
    });

and in set_alaram Activity get Double value from Bundle as

Bundle bundle = this.getIntent().getExtras();

Double lat = bundle.getDouble("lat");
