In order that my connection to ioio will not die upon the phone screen shutting
down, I put most of the ioio activity into a separate class.
I have a text view and a button defined on the main activity.
I defined a constructor in IoioTerbiumActivity which takes as an input the
MainActivity object. That way I can control the text view and button from
inside IoioTerbiumActivity.
When I tried the project, it showed the text view and the button but clearly
did not start my ioio class.
It clearly doesn't make sense to create the class and then call startActivity
with a new intent. If I just call startActivity, how do I bring across the
parent class?
If I use the my1 from the constructor, what is the proper way to start the
activity?
public class MainActivity extends AppCompatActivity {
TextView timerView;
int runState = 0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
timerView = (TextView) findViewById(R.id.timerView);
Button b = (Button) findViewById(R.id.startBut);
b.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String txtTmp = getString(R.string.start_lab);
Button b = (Button) v;
switch (runState) {
case 0:
case 1:
txtTmp = getString(R.string.stop_lab);
runState++;
break;
case 2:
runState++;
break;
default:
runState = 0;
break;
}
b.setText(txtTmp);
}
});
// IoioTerbiumActivity my1 = new IoioTerbiumActivity(this);
// startActivity(new Intent(this,IoioTerbiumActivity.class));
}
}
