Developing a mobile app in android-studio I have a ListView and I want to get the event in which when I select an Item from the list I show a certain String in a TextView .
For example:
TextView1 the String1
TextView1 the String2
For now I can present the data but loading a Activity with a TexView for each Item.
How can I make it work dynamically for all my Items?
Define the listener OnItemClickListener() to your ListView to detect the event when clicking on an item in the list, by selecting item A we can define which is the first and would have the position 0, and item B the second the position 1; according to the selection of the item, you add the desired text in your TextView :
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
switch (position) {
case 0: //Seleccion item A
miTextView1.setText("Texto String1");
break;
case 1: //Seleccion item B
miTextView1.setText("Texto String2");
break;
default:
miTextView1.setText("");
}
}
});
You could do it by assigning a new method to the ListView:
listView.setOnItemClickListener
With this method you get the object of the row and then using its attributes you can paint the text you want in any component.
Good luck! : D
