java - 当我点击 "Generate"按钮时只工作一次

Question

我的按钮有问题，例如，当我点击按钮 StartGame“再试一次”，然后我玩游戏时，生成按钮不起作用。

我认为发生这个问题是因为按钮在其他代码之前的 oncreate 方法中

Answer 1

您的问题是，当您首先单击按钮时，progressState 计数到 100 并关闭对话框。每次你再次点击按钮时，progressState 仍然保持在 100 或更多。

在按钮的 onClick 方法中重置 progressState。

它应该是这样的:

generate = (Button) findViewById(R.id.generate);
        generate.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                progressState = 0;
                showProgressDialog();
            }
        });
