Salut,

c'est mon premier post :)

je veux faire une button qui affiche une listeview et dans la list il y a un textEdit pour la recherche dans la liste (filtrage)

mais ce code montre l'erreur d'impossible démarrer l'activity

public void onCreate(Bundle savedInstanceState) {
	super.onCreate(savedInstanceState);
	setContentView(R.layout.index);
this.findViewById(R.id.btngetshedule).setOnClickListener(
			new Button.OnClickListener() {

				@Override
				public void onClick(View v) {
					setContentView(R.layout.main);
					vaccinList();
				}
			});

Cursor c2 = db.vaccinchild();
	startManagingCursor(c2);
	 final SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,
			R.layout.vaccinlist, c2, new String[] { DBAdapter.doctor,
					DBAdapter.child_name, DBAdapter.date_received },
			new int[] { R.id.txtvaccin, R.id.txtchild, R.id.txtdate });
	 setListAdapter(adapter);
	EditText txtFilter = (EditText) findViewById(R.id.txtsearch);
	txtFilter.addTextChangedListener(new TextWatcher() {
		public void afterTextChanged(Editable s) {
			adapter.getFilter().filter(s);				
		}
		public void beforeTextChanged(CharSequence s, int start, int count,
				int after) {adapter.getFilter().filter(s);
		}
		public void onTextChanged(CharSequence s, int start, int before,
				int count) {
			adapter.getFilter().filter(s);
		}
	});
}
