In my app i am trying to set TextView as Strikethrough while clicking on list item. But Listview clik item is not working.
Here is the code:
listView = ( ListView ) findViewById(R.id.listview);
SimpleAdapter adapter = new SimpleAdapter( this, aList, R.layout.add_list_detail,
new String[] { "txt", "cur" }, new int[] { R.id.txt, R.id.cur } );
// Setting the adapter to the listView
listView.setAdapter(adapter);
Button btnAdd = (Button) findViewById(R.id.btnAdd);
btnAdd.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent details = new Intent(AddNewList.this, AddNewGrocery.class); // Call
startActivityForResult(details, 1);
}
});
listView.setClickable(true);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
// Object o = lv.getItemAtPosition(position);
/* write you handling code like...
String st = "sdcard/";
File f = new File(st+o.toString());
// do whatever u want to do with 'f' File object
*/
TextView item = (TextView) arg1.findViewById(R.id.txt);
item.setPaintFlags(item.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
}
});
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1) {
if(resultCode == RESULT_OK){
Bundle b = data.getExtras();
if ( b!= null ){
String strName=data.getStringExtra("name");
String strQty=data.getStringExtra("quantity");
System.out.println(strName);
System.out.println(strQty);
SimpleAdapter adapter = new SimpleAdapter( this, aList, R.layout.add_list_detail,
new String[] { "txt", "cur" }, new int[] { R.id.txt, R.id.cur } );
HashMap<String, String> hm = new HashMap<String,String>();
hm.put("txt", strName);
hm.put("cur",strQty);
aList.add(hm);
// Keys used in Hashmap
String[] from = {"txt","cur" };
// Ids of views in listview_layout
int[] to = {R.id.txt,R.id.cur};
listView.setAdapter(adapter);
adapter.notifyDataSetChanged();
}
}
if (resultCode == RESULT_CANCELED) {
//Write your code if there's no result
}
}
}
I didn't find the problem on your code but I post you the full code which works:
