您可以设置一个监听TextView的。 – Raghunandan

你想要什么？那是ListView还是TextView？ – anuruddhika

listView.setOnItemClickListener(new OnItemClickListener() { 
    @Override 
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
    Toast.makeText(getApplicationContext(), 
     "Click ListItem Number " + position, Toast.LENGTH_LONG) 
     .show();

感谢您的回复。在上面我只添加文本layout.how我可以将文本转换为文本视图？ – PRK449

设置onclickListener您TextView。

就像这样： -

TextView = textView (TextView) findViewById(R.id.TEXTVIEW_ID); 
textview.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 

      } 
     });

您可以设置的ArrayList到ListView的这个样子。

private ListView lv;

在onCreate方法

lv = (ListView) findViewById(R.id.listView1);

变化这一行listItems.add(all.get(0)+" \n venue:"+all.get(1)+" Price:"+all.get(3));这样。

listItems.add("ID"+all.get(0)); 
listItems.add("Venue"+all.get(1)); 
......................... etc

然后添加到addapter

 ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
    this, 
    android.R.layout.simple_list_item_1, 
    listItems); 

    lv.setAdapter(arrayAdapter);

之后，你可以set OnItemClickListner这样

lv.setOnItemClickListener(new OnItemClickListener() { 
public void onItemClick(AdapterView<?> arg0, View view, int position, long id) { 
      // Put your custom code here 
     } 
});

添加这activity_full_details.xml

<ListView 
     android:id="@+id/listView1" 
     android:layout_width="288dp" 
     android:layout_height="330dp" 
     android:layout_alignParentTop="true" 
     android:layout_centerHorizontal="true" 
     android:layout_marginTop="62dp" > 
</ListView>

检查我的更新 – anuruddhika

在上面我添加文本最初到'ArrayList'，然后添加到布局不能添加此'text.setText（“您的文本”）''同时添加到'arrylist' – PRK449

它很简单，这个：

txtView.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     // TODO Auto-generated method stub 
    } 
});

希望它有帮助。

感谢您的回复。在上面我最初将文本添加到ArrayList，然后添加到布局不能将文本转换为'textview'，同时添加到'arraylist' – PRK449

这是很简单的，那样做：

TextView textView = (TextView) findViewById(R.id.yourtextview); 
textView.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      // Codes for action 
     } 
    });

更新 Converting string into TextView?

TextView idText = new TextView(this); 
    idText.setText(row.get(0).toString()); 
    tableRow.addView(idText); 

    TextView storeText = new TextView(this); 
    storeText.setText(row.get(1).toString()); 
    tableRow.addView(storeText); 

    TextView maggiText = new TextView(this); 
    maggiText.setText(row.get(2).toString()); 
    tableRow.addView(maggiText);
