是否有人能夠明白爲什麼我的名字的字符串沒有附加到值?組合字符串不附加到值
public void setNames() {
//*******************//
//***DATABASE INFO***//
//*******************//
DBAdapter db = new DBAdapter(this);
if (totalPlayerCount >= 1){
//**********************//
//***SET PLAYER NAMES***//
//**********************//
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Player " + nameLoop);
alert.setMessage("Name:");
// Set an EditText view to get user input
final EditText input = new EditText(this);
alert.setView(input);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
String newName = "name"+nameLoop;
// If i put "name1" here like so, the value "wow" stays with "name1" all the way to the database and does not end up null
name1 = "wow";
newName = input.getText().toString(); <-- newName should be name1, name2, name3, name4 each time around. If i do a simple Toast, it displays name1, name2, etc. But when i insert those values into the database, they are all null.
setNames();
}
});
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// Canceled.
}
});
alert.show();
nameLoop++;
}
if (totalPlayerCount == 0){
db.open();
db.insertPlayers(String.valueOf(name1), String.valueOf(name2), String.valueOf(name3),
String.valueOf(name4));
db.close();
AlertDialog.Builder myAlertDialog = new AlertDialog.Builder(this);
//myAlertDialog.setTitle("Saved");
myAlertDialog.setMessage("Names saved");
myAlertDialog.setPositiveButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
return;
} });
myAlertDialog.show();
}
totalPlayerCount--;
return;
}
這裏是同一剪輯剛剛打破的是我有
public void onClick(DialogInterface dialog, int whichButton) {
String newName = "name"+nameLoop;
// If i put "name1" here like so, the value "wow" stays with "name1" all the way to the database and does not end up null
name1 = "wow";
newName = input.getText().toString(); <-- newName should be name1, name2, name3, name4 each time around. If i do a simple Toast, it displays name1, name2, etc. But when i insert those values into the database, they are all null.
setNames();
}
});
當你調用insertPlayers(...)調用String.valueOf(String)只是創建開銷,沒有有用的工作完成。 name1在哪裏申報? –
name1-4在班級一開始都是公開的字符串..我想我可能會看到最新的錯誤,但不知道如何避開它。 我設置了newName =「name」+ nameLoop;它變成name1 但在此之後,newName = input.getText()。toString(); 這意味着newName不再是name1。 – Rob
我想我需要創建一個數組或東西?名稱[]或類似的東西?不確定,但我需要名稱每次都從name1更改爲name2。 – Rob
