Question

我想随机显示5个xml布局，并且我也会点击相应的按钮，每个都出现xml文件。以下代码工作得非常棒.---- ** 我已经在xml文件的每次shuffle上放了0.75秒的延迟。在这个延迟中我有一个声音可以播放。我没有真的想法如何实现这一点。在下面的代码中我使用了Switch-Case，但它无法正常工作。我的要求是如果我点击xml file1上的Button，我想播放Sound1，如果Button来自Xml文件5 ，我想播放相应的Sound5等等......就像那样0.75秒并移动到下一个XML文件并重复循环。 * ----

public class ReceivingActivity extends Activity{

    Random random = new Random();

任何帮助都非常有用。

Answer 1

您可以使用android：标签来区分按钮。

<Button
    ...
    android:tag="1"/>

然后在代码中检索标记

mButton = (Button)findViewById(R.id.btnid);
int id = Integer.parseInt(mButton.getTag());

switch(id) {
    ...
}

在按钮上显示图像（或媒体）单击随机更改的布局
