如何从 Android 中的普通 Activity 启动 MapActivity

Question

I created a launcher MapActivity from new project and it is working fine. Now I want start a MapActivity from normal activity like MainActivity.java to MapsActvity.java such that from MainActivity , it should send latitude and longitudes values for marker to show in MapActivity when a button in the main layout is clicked. I am thinking of using intent but I don't know how do it.

Intent i = new Intent();
startActivity(i);

Answer 1

In MainActivity on button click 

Intent intent = new Intent(this, MapsActvity.class);
intent.putExtra("latitute", 34.8098080980);
intent.putExtra("longitude", 67.09098898);
startActivity(intent);

In MapActivity.java onCreate method get lattitude and longitude and use it
        Intent intent1 = getIntent();
        double lat = intent1.getDoubleExtra("latitute", 0);
        double lng  = intent1.getDoubleExtra("longitude",0);

Thanks for your answer USKMobility, but i had to modify your code to use it :

 Intent intent = new Intent(MainActivity.this, MapsActivity.class);
 intent.putExtra("latitute", 34.8098080980);
 intent.putExtra("longitude", 67.09098898);
 startActivity(intent);

Thanks!

You can directly use this

 Intent geoIntent = new Intent(android.content.Intent.ACTION_VIEW, Uri
                                .parse("geo:0,0?q=" + address));
 startActivity(intent);

Pass the address , the above code uses inbuilt Maps and shows the address specified.

Place this in your Manifest file

<uses-library android:name="com.google.android.maps" />
