new Android developer here. I'm doing a form that let's users set up some search criteria before searching in a SQLite db. Part of the form includes some checkboxes. How do I go about their values in a "best practice" sense?
I'm used to doing PHP, so I would set up a method that returns an array or object with all the values, and then call that inside the 'onClick' method, but is that also a good idea in Java?
My code looks like this:
// Setup a listener, and event handler for the onClick event of the button
buttonFind.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
String text = "Button clicked";
int duration = Toast.LEN开发者_如何学JAVAGTH_SHORT;
Context context = getApplicationContext();
Toast toast = Toast.makeText(context, text, duration);
toast.show();
}
});
It's probably better to give more details in your question. You don't show anywhere in your code where you define your checkbox... so i'm going to make some assumptions:
I'll assume that somewhere in your onCreate() method of your activity you have something that looks like this:
CheckBox myCheckbox = (Checkbox) findViewById(R.id.my_checkbox);
If you want to find out if the checkbox is checked or not from your button's onClick() method (since you posted it above), you can do something like this:
boolean isMyCheckboxChecked = myCheckbox.isChecked();
Hope that works out for you. Next time try to be more clear in your questions.
