我试图在复选框的onClick方法中使用intent，但是我得到的错误是方法startActivity未定义，并且构造函数Intent（new View.OnClickListener等）也是未定义的 . 这是我的代码：
错误在 com.tutorials.hp.tanding.Main.onClick(Main.java:24)
public class Main extends Activity implements View.OnClickListener{
private TeamHandler handler;
private List<Team> teams;
ListView lv;
@Override
public void onClick(View v) {
Intent intent = new Intent(Main.this, NewTeam.class);
startActivity(intent);
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
handler = new TeamHandler(getApplicationContext());
Button btn_add_new = (Button) findViewById(R.id.btn_add_team);
btn_add_new.setOnClickListener(this);
lv = (ListView) findViewById(R.id.lv_team_list);
loadTeamData();
lv.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
Intent intent = new Intent(Main.this, TeamDetails.class);
intent.putExtra("id", teams.get(position).getID());
intent.putExtra("name", teams.get(position).getName());
intent.putExtra("phone", teams.get(position).getPhoneNumber());
intent.putExtra("email", teams.get(position).getEmail());
intent.putExtra("address", teams.get(position).getPostalAddress());
intent.putExtra("photograph", teams.get(position).getPhotograph());
startActivity(intent);
}
});
}
private void loadTeamData(){
// Code for loading team list in ListView
// Reading all teams
teams = handler.readAllTeams();
// Initialize Custom Adapter
CustomAdapter adapter = new CustomAdapter(this, teams);
// Set Adapter to ListView
lv.setAdapter(adapter);
// See the log int LogCat
for(Team c : teams){
String record = "ID=" + c.getID() + " | Name=" + c.getName() + " | " + c.getPhoneNumber();
Log.d("Record",record);
}
}
}
