I'm trying to generate form elements from a template when the user clicks on a button. I created the template and the container layout for the new forms with XML. Its successfully generating the first form where I'm telling it to generate, but when I try to generate more forms beyond the first one its giving me an error: "the specified child already has a parent. You must call removeView() on the child's first parent". Any clue as to what I should do so as to generate more than one element? I've tried changing the id of the newly created forms but that's giving me a null pointer exception and crashing. Thank you.
public class MakeQuestion extends Activity implements OnClickListener{
private static final int MY_BUTTON = 9000;
int templateID = 1;
Button b;
Button target;
View insertPoint;
Button testTemplate;
View v1;
RelativeLayout.LayoutParams templateParams;
LayoutInflater vi;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.make_question);
Initialize();
}
public void Initialize(){
//button for adding new forms
b = (Button) findViewById(R.id.makeLayoutButton);
b.setOnClickListener(this);
//get the template form to be duplicated
vi = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v1 = vi.inflate(R.layout.form_template, null);
//set the params for the element that will have dynamically generated content below it
templateParams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
//container where forms will be contained in
insertPoint = findViewById(R.id.questionsContainer);
//view where new form will go below
View belowContainer = findViewById(R.id.questionTemplateFake);
//set id for layout params of view
belowContainer.setId(1);
//set rule for new forms to go below view 'belowContainer'
templateParams.addRule(RelativeLayout.BELOW, belowContainer.getId());
}
public void onClick(View v) {
switch (v.getId()) {
case R.id.makeLayoutButton:
v1 = vi.inflate(R.layout.form_template, null);
//add view to the insertPoint
((LinearLayout) insertPoint).addView(v1);
break;
}
}
}
Added forms should go in "questionsContainer" which is set to be below "questionTemplateFake"
