Hi, I'm new on Android and I just made my first application openning a
new Activity with a button and some other stuff but now I want to do
something that have to be refreshed every little time or as fast as
possible like a counter.
When you program in C or Java you can make a loop and a counter adding
1 so yo can see 1.. 2 .. 3 ...4 .... I would like to be able to do
that when the program is in the foreground. I've tried this code but
it wont even start I get the has stopped unexpectivly when I try to
execute it in the emulator. I also tried with the onStart method and a
method I made my own and calling it from the onCreate but I get the
same error.
What I really want to do is to get the sound level in the mic while
the program is running, I have the code for that but I don't know how
to make it check the sound level periodically.
Thank you.
package android.manual1;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
public class Manual1 extends Activity {
/** Called when the activity is first created. */
//@Override
static private int variable = 1;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public void onResume (){
TextView text = (TextView) findViewById(R.id.count);
do{
text.setText("Contador:"+variable);
variable=variable+1;
}while (variable<100);
}
}
