How do I pass data between activities in Android?

Posted on January 26, 2013 by Janaki in Android / 0 Comment(s)

Add the following code in your current activity

<strong><code>Intent i = new Intent(getApplicationContext(), NewActivity.class);
i.putExtra("new_variable_name","value");
startActivity(i);</code></strong>


Then in the new Activity, retrieve those values:

<code>Intent i = new Intent(getApplicationContext(), NewActivity.class);

i.putExtra("new_variable_name","value");

startActivity(i);</code>

Then in the new Activity, retrieve those values:

<strong><code>Bundle extras = getIntent().getExtras();
if (extras != null) {
    String value = extras.getString("new_variable_name");
}

</code></strong>

<code>Bundle extras = getIntent().getExtras();

if (extras != null) {

String value = extras.getString("new_variable_name");

}

</code>

Add the following code in your activity class

Intent intent= new Intent(context, YourActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);

Change your Manifest by

Intent intent= new Intent(context, YourActivity.class);

intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);

Change your Manifest by

&lt;activity
    android:name=".ResultActivity"
...
   <strong> android:launchMode="singleTask"</strong>
    .....
&gt;
&lt;/activity&gt;

<activity

android:name=".ResultActivity"

...

android:launchMode="singleTask"

.....

</activity>
