等待触发动作

Question

我希望触发一个 while 循环，但仅在用户选择一个选项之后。现在由于某种原因，即使在用户选择一个选项之前，它也会自动遍历整个代码块。我如何强制它等待继续，直到用户选择某些内容？

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(); 不会阻止或执行任何操作来等待响应，但 onclick 是由用户响应触发的。请记住这将在主线程上运行。
