我尝试使用3个选项创建一个alertdialog，其中一个选项会打开另一个带有editext的alertdialog。
问题是，一旦第二个alertdialog被打开，我无法设法完成或结束它之前的那个，它会隐藏在第二个对话框下面，当我开始输入editext时再次弹出。 void generateAlertDialog(long timeSpent) {
AlertDialog.Builder builder = new AlertDialog.Builder(
GActivity.this);
builder.setMessage(
"The time stayed in the game is " + timeSpent + "s")
.setTitle("You Lose")
.setPositiveButton("Reset Game",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int id) {
finish();
Intent intent = new Intent(GActivity.this, GActivity.class);
Bundle setting = configureGame(RWIDTH, BSIZE, Speed);
intent.putExtra("setting", setting);
startActivity(intent);
}
})
.setNeutralButton("Score List",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int id) {
// User clicked score button
AlertDialog.Builder builder = new AlertDialog.Builder(
GActivity.this);
builder.setMessage(
"Please input the player's name");
setTitle("Score");
final EditText input = new EditText(GActivity.this);
builder.setView(input)
.setPositiveButton("Reset Game",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int id) {
}
})
.setNegativeButton("Exit",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int id) {
}
});
// 3. Get the AlertDialogfrom create()
AlertDialog dialogsnd = builder.create();
// 4. Show dialog
dialogsnd.show();
}
})
.setNegativeButton("Exit",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,
int id) {
finish();
// User cancelled the dialog
}
});
// 3. Get the AlertDialogfrom create()
AlertDialog dialog = builder.create();
// 4. Show dialog
dialog.show();
}

Just u need to put dialog.dismiss(); where u want to close alert box(i.e previous one) as below
void generateAlertDialog(long timeSpent) {
AlertDialog.Builder builder = new AlertDialog.Builder(
GActivity.this);
builder.setMessage(
"The time stayed in the game is " + timeSpent + "s")

如果为true，您可以创建一个调用上一个警报的布尔值。将第二个警报放入新方法中。从第一个警报调用第二个警报时，请确保将第一个警报的布尔值设置为false，关闭对话框，然后调用第二个警报。这样第一个对话框就不会再出现了。

在创建新的Dialog之前调用dialog.dismiss();。
