Listactivity具有多个按钮和多个视频

标签： android android-intent

我有一个listactivity app，由5行组成，每行包含一个TEXT和5个BUTTON， 文本和按钮都是可点击的，文本将打开MyDay活动，这是textview，当你点击任何按钮它必须打开视频视图屏幕，它的工作正常如下图所示：

enter image description here

但我的问题是：

我可以通过每行中的5个按钮分配五个不同的视频。

我试图为每个按钮设置不同的视频，所以：

25按钮打开25个不同的视频。

我的意思是：

第一个行中的按钮（一个）将打开 video_1

第一个行中的按钮（两个）将打开 video_2

第一个行中的按钮（三个）将打开 video_3

第一个行中的按钮（四个）将打开 video_4

第一个行中的按钮（五个）将打开 video_5

第二行中的按钮（一个）将打开 video_6

第二行中的按钮（两个）将打开 video_7

等到第五行的最后一个按钮

我无法实现这一点。

任何建议都将受到赞赏

感谢

我的代码：

ListButtons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" };
private int[] ids = { R.id.button1, R.id.button2, R.id.button3,

             R.drawable.row_24, R.drawable.row_25}};

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
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder;

        holder = new ViewHolder();
        holder.textView = (TextView) convertView
                .findViewById(R.id.row_label);

        holder.bt1 = (Button) convertView.findViewById(R.id.button1);
        holder.bt2 = (Button) convertView.findViewById(R.id.button2);
        holder.bt3 = (Button) convertView.findViewById(R.id.button3);
        holder.bt4 = (Button) convertView.findViewById(R.id.button4);
        holder.bt5 = (Button) convertView.findViewById(R.id.button5);
    } else {

    String s = mClasses[position];
    holder.textView.setText(s);

            Integer pos = (Integer) v.getTag();
            Intent ourIntent = new Intent(mContext, MyDay.class);

                                }

My_videos班级： 

  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() 
                + "/" + R.raw.video_2)); 
         vid.setMediaController(new MediaController(My_videos.this));

         else if (night.equalsIgnoreCase("button3")) { 
     vid.setVideoURI(Uri.parse("android.resource://" + getPackageName() 
                + "/" + R.raw.video_3)); 
         vid.setMediaController(new MediaController(My_videos.this));
             vid.requestFocus();
             vid.start();         } 
         else if (night.equalsIgnoreCase("button4")) { 
     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，但结尾为为每个按钮显示相同的视频，即（video_5）。

3 个答案:

答案 0 :(得分：1)

在此链接https://gist.github.com/3463215我发布了一个My_videos类的版本，可以执行您想要的操作。基本上，在MyArrayAdapter课程中点击Button时，您会在Intent中发送点击该按钮的行+在该行中点击的确切Button 。然后在My_videos类中，您将获得这些数字，并在数组数组结构数组中轻松找到正确的视频。

答案 1 :(得分：0)

你有5个按钮，25个链接，5行，如果你设置5个监听器（对于每个按钮1）你可以选择这样的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);
    }
});

= getView(position)中的rowPosition =是简单的转换数字，按钮位置是您的v.getTag()按钮数，现在为1。

播出白色你可以选择25个链接：当你在你的第2行中点击时，第3个按钮，链接ID将是2 * 5 + 3 = 13。所以在你的secund行中，3 buttom将获得13个链接。

答案 2 :(得分：0)

您可以获得所有视频的相同视频，所有两个视频的视频相同，因为所有行中的所有视频ID都相同，等等。

所以，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;
            }
        }
}

现在也将此位置添加为您的意图的额外。这样您就可以知道单击哪一行等等。
