if(!player.getPlaying()&&newGameCreated&&reset)
{
Bitmap b2 = BitmapFactory.decodeResource(getResources(), R.drawable.coollogo);
canvas.drawBitmap(b2, WIDTH/2 - 440, HEIGHT/2 - 360, paint);
canvas.drawRect(380, 380,630,465 , paint);
canvas.drawBitmap(b1, WIDTH/2 - 260, HEIGHT/2 + 20, paint);
}
}
我现在有这个:
我想要这样:
我想要一个进度条在那个地方,这样你们可以在游戏中升级。
没有加载条,只有一个进度条,这样你就可以看到你在升级中有多远了!
有人能帮我做这个吗?我该怎么做
非常感谢
ProgressBar progressBar = new ProgressBar(activity, null, android.R.attr.progressBarStyleSmall);
要显示progressbar,请写入progressbar.show()代码>
对于hide writeprogressbar.disclose()代码>
例如:-
如果我复制您的代码并将其粘贴到我的代码上,它将不起作用。可能是因为您编写了.show()和.disease()方法,但这些方法不连续地编写progressbar.disease()
调用progressbar.show()时会出错;您在哪里初始化了ProgressBar..?ProgressBar.setVisibility(View.VISIBLE)代码>使用此选项以哪种方式显示?以进度条的形式?还是只发短信?
