我有一个 listactivity 应用程序，由 5 行组成，每行包含一个 TEXT 和 5 BUTTON，文本和按钮都是可点击的，文本将打开 MyDay 活动，即 textview，当您单击任何按钮时，它必须打开 videoview 屏幕，它的工作正常如下图：

在此处输入图像描述

但我的问题是：

我可以分配五个不同的视频，通过每行的 5 个按钮打开。

我试图为每个按钮设置不同的视频，所以：

25 个按钮打开 25 个不同的视频。

我的意思是：

第一行的按钮（一个）将打开video_1

第一行的按钮（二）将打开video_2

第一行的按钮（三）将打开video_3

第一行的按钮（四个）将打开video_4

第一行的按钮（五）将打开video_5

第二行的按钮（一个）将打开video_6

第二行的按钮（两个）将打开video_7

依此类推，直到第五行的最后一个按钮

我做不到。

任何建议将被认真考虑

谢谢

我的代码：

列表按钮类：

 public class ListButtons extends ListActivity {
String classes[] = {"First",  "Second", "Third","Fourth", "Fifth" }; 

@Override
protected void onCreate(Bundle savedInstanceState) {
    this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);

    setListAdapter(new MyArrayAdapter(this, classes));  }}

MyArrayAdapter 类：

 public class MyArrayAdapter extends ArrayAdapter<String> {

private final String[] mClasses;
private Context mContext;
private Typeface tf;
private LayoutInflater mInflater;
private String[] mData = { "button1", "button2", "button3", "button4",
        "button5" };

public MyArrayAdapter(Context context, String[] classes) {
    super(context, 0, classes);
    mClasses = classes;
    mContext = context;
    tf = Typeface.createFromAsset(context.getAssets(), "BFantezy.ttf");
    mInflater = LayoutInflater.from(context);
                              }

@Override

        holder.bt5 = (Button) convertView.findViewById(R.id.button5);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }
    String s = mClasses[position];
    holder.textView.setText(s);

    int[] rowDr = rowDrawables[position];

            Intent ourIntent = new Intent(mContext, MyDay.class);

                                }

My_videos 类：

  public class My_videos extends Activity {  
private VideoView vid;  
String night;  
/** Called when the activity is first created. */  
@Override  
public void onCreate(Bundle savedInstanceState) {   
    super.onCreate(savedInstanceState);   
    setContentView(R.layout.video); 

    Bundle bdl = getIntent().getExtras(); 
    night = bdl.getString("video");   
    vid = (VideoView) findViewById(R.id.videoView1); 

    if (night.equalsIgnoreCase("button1")) {    
    vid.setVideoURI(Uri.parse("android.resource://" + getPackageName()
                + "/" + R.raw.video_1));
        vid.setMediaController(new MediaController(My_videos.this));  
        vid.requestFocus();    
        vid.start(); }  

         else if (night.equalsIgnoreCase("button2")) {   
     vid.setVideoURI(Uri.parse("android.resource://" + getPackageName()

             vid.start(); }  

                        }}

更新：

我尝试修改 My_videos 类，如下面的代码，但它以每个按钮显示相同的视频结尾，即 (video_5)。

在这个链接https://gist.github.com/3463215我已经发布了一个版本的My_videos类，它会做你想要的。基本上，在单击MyArrayAdaptera 的类中，Button您将发送单击Intent该 Button 的行 + 在该行中单击的确切值Button。然后在My_videos课堂上，您将获得这些数字，并在数组数据结构数组中轻松找到正确的视频。

您有 5 个按钮、25 个链接、5 行，如果您设置 5 个侦听器（对于每个按钮 1），您可以像这样选择 uri：

button1,button2,button3,button4,button5;

button1.setOnclickListener(new View.onClickListener{
    public void onClick(View v){
        Integer pos = (Integer) v.getTag();
        Intent ourIntent = new Intent(mContext, MyDay.class);
        ourIntent.putExtra("cheese", mClasses[rowPosition*5+buttonPostion]);
        mContext.startActivity(ourIntent);
    }
});

rowPosition=ingetView(position)是简单的当前 convertView 编号，按钮位置是您的v.getTag()按钮编号，现在是 1。

播种白色，您可以选择 25 个链接：例如，当您在第 2 行获得 onclick 时，第 3 个按钮的链接 ID 将为 2*5+3=13 。因此，在您的第二排中，3 按钮将播放 13 链接。

你得到所有的相同的视频，所有的两个都有相同的视频，依此类推，因为你对所有行中的所有的都有相同的 ID，依此类推。

因此，在 onClick 中执行此操作：

public void onClick(View v) {
        String night = null;
        int position = yourListView.getPositionForView((View) v.getParent())
        for (int i = 0; i < ids.length; i++) {
            if (v.getId() == ids[i]) {
                night = mData[i];
                break;
            }
        }
}

现在将此职位也添加为您的意图的额外内容。这样您就会知道单击了哪一行，依此类推。
