Hi,
Here is a simple example of how flags maybe helpful while calling back
button (btw by "back button" i mean a phone back button):
public class BodyActivity extends Activity {
OnClickListener mNextButtonListener = new OnClickListener() {
@Override
public void onClick(View v) {
restartActivity();
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.body);
Button nextButton = (Button)findViewById(R.id.next_button);
nextButton.setOnClickListener(mNextButtonListener);
}
private void restartActivity() {
Intent i = new Intent(getBaseContext(), BodyActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivity(i);
}
}
if you don't use the flag in this particular example it will put the
same activity to the history stack and every time you click back
button it will go back through the stack.
If that doesn't help then pls provide more details or an example of
what you are trying to do.
