Hello
>>To summarize: Activities don't have constructors! How do I send data
>>to them from their parent activity???
we can send data from parent activity to childs, using Intent
for example:
In parent activity,
Intent intent = new Intent(this,com.sample.aaa.class); //aaa is
child activity
intent.putExtra("ARG1","value1");
intent.putExtra("ARG2","value2");
StartActivity(intent);
In Child activity (aaa) use Bundle to get the data
public void onCreate(Bundle som) {
super.onCreate(som);
Intent intent = this.getIntent();
Bundle b = intent.getExtras();
String sVal1 = b.getString("ARG1");
String sVal2 = b.getString("ARG2");
....
...
}
