Question

我有一个listactivity应用程序，每行包含TEXT和BUTTON，文本和按钮都必须是可点击的（我试图获得它），当点击文本时它将打开MyDay活动，当点击按钮时它将打开My_videos活动

当您打开应用程序并单击任何按钮时，它会发生什么，它在所有行中的任何按钮中都没有单击操作，但是当您单击任何行文本以便它将打开MyDay活动然后单击仅第一行，它将打开My_videos活动，即videoview，但同时其他按钮在其余行中无法点击。

任何建议都将受到赞赏，

感谢。

我的代码：

MyArrayAdapter类：

 public class MyArrayAdapter extends ArrayAdapter<String> {
private final Activity context;
private final String[] classes;
Button bt1, bt2, bt3, bt4, bt5;   

Typeface tf;

public MyArrayAdapter(Activity context, String[] classes) {
    super(context, R.layout.row, classes);
    this.context = context;
    this.classes = classes;
              }

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    tf=Typeface.createFromAsset(context.getAssets(),"BFantezy.ttf"); 
    LayoutInflater inflater = context.getLayoutInflater();
    View rowView = inflater.inflate(R.layout.row, null, true);
    TextView textView = (TextView) rowView.findViewById(R.id.row_label);
    Button bt1=(Button) rowView.findViewById(R.id.button1); 
    Button bt2=(Button) rowView.findViewById(R.id.button2); 
    Button bt3=(Button) rowView.findViewById(R.id.button3); 
    Button bt4=(Button) rowView.findViewById(R.id.button4); 
    Button bt5=(Button) rowView.findViewById(R.id.button5); 

    String s = classes[position];
    textView.setText(s);
    ((TextView)textView).setTypeface(tf); 


if ( s.startsWith("First")) {

    bt1.setBackgroundResource(R.drawable.ic_launcher);
    bt2.setBackgroundResource(R.drawable.ic_launcher); 
    bt3.setBackgroundResource(R.drawable.ic_launcher); 
    bt4.setBackgroundResource(R.drawable.ic_launcher); 
    bt5.setBackgroundResource(R.drawable.ic_launcher); }

    bt4.setBackgroundResource(R.drawable.ic_launcher); 
    bt5.setBackgroundResource(R.drawable.ic_launcher); }        

return rowView;  }}

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) {

    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.b));
         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.bb)); 
         vid.setMediaController(new MediaController(My_videos.this));
             vid.requestFocus(); 
             vid.start(); } 

     else if (night.equalsIgnoreCase("button3")) {

                                      } }

你在onItemCLik方法

中定义点击监听器时做错了

在基本适配器的getView方法中为TextView和Button设置一个CLick Listener ....... i，e从OnItemClikc方法中删除所有点击监听器

public View getView(final int position, View convertView, ViewGroup parent) {
    tf=Typeface.createFromAsset(context.getAssets(),"BFantezy.ttf"); 
    LayoutInflater inflater = context.getLayoutInflater();
    View rowView = inflater.inflate(R.layout.row, null, true);
    TextView textView = (TextView) rowView.findViewById(R.id.row_label);
    textView.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            // do what ever do want to ie open activity 
            //must use postion to get that item  
        }
    });
    Button bt1=(Button) rowView.findViewById(R.id.button1); 
    bt1.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            Intent intent = new Intent();    
            intent.setClass(ListButton.this, My_videos.class); 
            //this will send the respective  string to intent class ; 
            intent.putExtra("video", classes[position].toString);

        }
    });
return rowView;  }}

您正在设置侦听器不正确。为了使听众能够工作，您必须单击ListView行一次以实际设置Buttons和TextView的听众。正确的方法是在布局视图时在getView方法中设置侦听器。

首先删除onListItemClick回调中的代码，然后修改适配器。我已经将您的适配器重写为更高效的版本（尽管可以进行更多改进）。由于代码很大，您可以在https://gist.github.com/3463215找到新的适配器。看看这是不是你想要的。

R.layout.video布局文件：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

<LinearLayout  android:layout_width="match_parent"
    android:layout_height="wrap_content" >
<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="One" />

<Button
    android:id="@+id/button2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
     android:text="Two" />

<Button
    android:id="@+id/button3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="three" />

<Button
    android:id="@+id/button4"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Four" />

<Button
    android:id="@+id/button5"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Five" />

</LinearLayout>

<VideoView
    android:id="@+id/videoView1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" />

</LinearLayout>
