我想从所选的选项中触发设置点击监听器...
这是我在选项上选择的代码
//cancel event added here
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// ClipData.Item menu_cancel_event=(ClipData.Item) findViewById(R.id.menu_cancel_event);
// int Id = item.getItemId();
switch (item.getItemId()) {
case R.id.menu_cancel_event:
eventMO.setIsDelete(1);
del();
return true;
}
return super.onOptionsItemSelected(item);
}
private void del() {
SQLiteDatabase db = dbHelper.getWritableDatabase();
final long Id = eventMO.getEventId();
db.delete("event", "Event_ID" + " = ?", new String[]{String.valueOf(Id)});
db.close();
}
这是我在点击监听器上的设置
btn_create_button = (Button) findViewById(R.id.create_button);
btn_create_button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Instantiate Progress Dialog object
prgDialog = new ProgressDialog(OccasionActivity.this);
// Set Progress Dialog Text
prgDialog.setMessage("Please wait...");
// Set Cancelable as False
prgDialog.setCancelable(false);
prgDialog.show();
UserMO userMO = dbHelper.getRingeeUserData(1);
eventMO.setText(custom_Text.getText().toString());
eventMO.setPlace(event_Place.getText().toString());
eventMO.setEndTime(end_Time);
eventMO.setStartTime(start_Time);
try {
//date and time format changed here
String eventDate = btn_Date.getText().toString();
DateFormat date = new SimpleDateFormat("dd-M-yyyy");
Date date1 = date.parse(eventDate);
DateFormat convertDate = new SimpleDateFormat(" yyyy-MM-dd hh:mm:ss");
eventDate = convertDate.format(date1);
eventMO.setEventDate(eventDate);
} catch (ParseException e) {
e.printStackTrace();
}
//eventMO.setEventDate(btn_Date.getText().toString());
eventMO.setRingeeUserId(userMO.getRingeeUserId());
//event update functionality added here
final Long hidden_Text2 = eventId2;
if ((eventMO.getText() != null) && (eventMO.getPlace() != null) && (eventMO.getEventDate() != null)) {
if (hidden_Text2 != null) {
eventMO.setEventId(hidden_Text2);
new AsyncTask<Void, Void, String>() {
@Override
protected String doInBackground(Void... arg0) {

通常，不会以编程方式调用android侦听器回调。这会在以后引起各种混乱。
因此，如果您希望在两个侦听器回调中运行代码，则可以在与两个回调（Activity或Fragment）相同的范围内创建一个方法。然后在你的回叫中你称之为该方法。
活动的示例：
class MyActivity extends Activity {
private void doOnCLickAndOnOptionSelected() {
// code
}
@Override
protected void onCreate(...) {
...
btn_create_button = (Button) findViewById(R.id.create_button);
btn_create_button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
doOnCLickAndOnOptionSelected();
}
}
...
someMenu.setOnOpttionsItemSelectedListener(new OnOpttionsItemSelectedListener {
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// ClipData.Item menu_cancel_event=(ClipData.Item) findViewById(R.id.menu_cancel_event);
// int Id = item.getItemId();
switch (item.getItemId()) {
case R.id.menu_cancel_event:
eventMO.setIsDelete(1);
del();
doOnCLickAndOnOptionSelected();
return true;
}
return super.onOptionsItemSelected(item);
}
}
}
}
