Let me just say that as someone with a lot of UI development
experience (in Android, SWT and Swing anyways), if you're looking to
programmatically push controls, your design is most likely wrong.
I have developed maybe 50-100 screens of GUIs and have never needed
that functionality. Consider this - you have a button that has some
anonymous inner class action handler. Normal, right?
So here's my save button code:
Button saveButton = (Button) findViewById(R.id.save_button);
saveButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
dataMgr.setUserName(userNumber,
nameEdit.getText().toString().trim());
finish();
}
});
Let's say we wanted the app to programmatically "press" that button.
How do I do it? Answer: That right there is a fundamentally wrong way
to look at it. We don't need to "press" it, we need to refactor it.
Consider adding this private method:
private void save() {
dataMgr.setUserName(userNumber,
nameEdit.getText().toString().trim());
finish();
}
Now change the button to:
Button saveButton = (Button) findViewById(R.id.save_button);
saveButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
save();
}
});
And when we want to "press" the button, instead, we just call save().
That can be applied to every situation in some form or another. You
should never have to fake input from the user and if you have critical
code that can only be called via a user input, your design is flawed
but you can usually fix it by moving that code out into private
methods.
