等待触发动作

Question

我希望触发一个while循环，但只有在用户选择了一个选项之后。由于某种原因，它甚至在用户选择一个选项之前就会自动吹过整个代码块。如何强制它等待用户继续选择？

case R.id.buttonSetPlayers:
        //**********************//
        //***SET PLAYER COUNT***//
        //**********************//
        AlertDialog.Builder builderPC = new AlertDialog.Builder(this);
        final CharSequence[] playerCount = {"1", "2", "3", "4"};
        builderPC.setTitle("Player Count");
        builderPC.setItems(playerCount, new DialogInterface.OnClickListener(){
            public void onClick(DialogInterface dialogInterface, int item) {
                Toast.makeText(getApplicationContext(), playerCount[item], Toast.LENGTH_SHORT).show();
                if (playerCount[item].equals("1")){
                    EntryScreen.this.totalPlayerCount = 1;

                }
                else if (playerCount[item].equals("2")){
                    EntryScreen.this.totalPlayerCount = 2;

                }
                else if (playerCount[item].equals("3")){
                    EntryScreen.this.totalPlayerCount = 3;

                }
                else if (playerCount[item].equals("4")){
                    EntryScreen.this.totalPlayerCount = 4;

                }
                return;
            }
        });
        builderPC.create().show();

I want it to wait to do this next part instead of doing it as soon as button is clicked.  Below...

###
        while (totalPlayerCount >= 1){
            setNames();
            totalPlayerCount--;
        }

        return;

将while循环放在onClick或onClick调用的方法中。 builderPC.create().show();不阻止或做任何事情等待响应，但onclick由用户响应触发。请记住，这将在主线程上运行。
