如何實現在動態佈局中實現添加更多視圖android

Question

我正在實現自定義線性佈局添加更多視圖檢索數據庫使用web服務在後臺進程中所有數據都是retrive消息和消息相關userimages還首先初始化加載消息之後通過在自定義佈局線性一個加載圖像

main.xml中

<?xml version="1.0" encoding="utf-8"?> 
<FrameLayout android:id="@+id/frameLayout1" android:layout_width="fill_parent" android:background="@android:color/white" 
xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="fill_parent"> 
    <ScrollView android:id="@+id/scrollView1" android:layout_height="wrap_content" android:layout_width="fill_parent"> 
     <LinearLayout android:layout_width="fill_parent" android:id="@+id/linearLayout2" android:layout_height="fill_parent"> 
      <LinearLayout android:layout_width="fill_parent" android:id="@+id/linearLayout3" android:layout_height="fill_parent"> 
       <ImageView android:id="@+id/person" android:layout_width="wrap_content" android:layout_height="wrap_content"></ImageView> 
       <TextView android:textColor="@android:color/black" android:id="@+id/textView1" android:layout_height="wrap_content" android:layout_width="wrap_content"></TextView> 
      </LinearLayout> 
     </LinearLayout> 
    </ScrollView> 
</FrameLayout> 

的CodeFile：

public class MYlist extends Activity 
{ 
    /** Called when the activity is first created. */ 
    List<MessageClass> messages; 
    int i=0,n=5; 
    ParseXMLString parse=new ParseXMLString(); 
    DataParsingComm dataparsing=new DataParsingComm(); 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     String xml="<spGetUserMessages><SearchLocation></SearchLocation><LoginUserID>125</LoginUserID></spGetUserMessages>"; 
     messages =parse.GetGetUserMessages(dataparsing.ILGetUserMessages(xml)); 


     addElements(messages,i,n); 
    } 

    protected void addElements(final List<MessageClass> messages2,int i,int n) 
    { 
     int k=0; 
    //((LinearLayout)findViewById(R.id.linearLayout1)).removeAllViews(); 

     for(int i1=i;i1<n;i1++) 
     { 
      LinearLayout ll1=((LinearLayout)findViewById(R.id.linearLayout2)); 
      ll1.setBackgroundResource(R.drawable.tabmessage); 
      Log.v("11111111","333"+ i1+ n); 
      if(k==i1) 
      { 
      for(int j1=i1;j1<n;j1++) 
      { 

      TextView msg=((TextView)findViewById(R.id.textView1)); 
      msg.setText(messages2.get(j1).getmessage()); 

      } 
      } 
      ImageView prsnImg=((ImageView)findViewById(R.id.person)); 
     try{ 
      String photoXml="<spGetUserPhoto><UserID>125</UserID></spGetUserPhoto>"; 

      String photoInfoFromDB=new DataParsingComm().ILGetImage(photoXml); 

      if(photoInfoFromDB.equalsIgnoreCase("anyType{}")||photoInfoFromDB.equals(null)) 
      { 
       prsnImg.setImageResource(R.drawable.person); 
      } 
      else{ 

       byte[] imgArry= Base64.decode(photoInfoFromDB); 

       Bitmap bit=BitmapFactory.decodeByteArray(imgArry,0,imgArry.length); 

       prsnImg.setImageBitmap(bit); 
      } 
     }catch (Exception e) { 
      e.printStackTrace(); 
     } 
     finally 
      { 
       System.gc(); 
       System.runFinalization(); 
      } 

     } 

    } 
}

我的問題是，每一次顯示一個項目的所有數據覆蓋的佈局，單個項目視圖如何通過一個顯示器意見線性佈局實現一個

請告訴我一些解決方案在此先感謝

那是因爲你總是選擇相同的兩個對象...

有什麼獲取我想你可能需要一個非常基本的方法：

爲主。 XML

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/frameLayout1" 
    android:layout_width="fill_parent" 
    android:background="@android:color/white" 
    android:layout_height="fill_parent"> 
    <ScrollView android:id="@+id/scrollView1" 
     android:layout_height="wrap_content" 
     android:layout_width="fill_parent"> 

    </ScrollView> 
</FrameLayout> 

的.java

public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     ScrollView scrollView = (ScrollView) findViewById(R.id.scrollView1); 

     LinearLayout topLinearLayout = new LinearLayout(this); 
     topLinearLayout.setOrientation(LinearLayout.VERTICAL); 

     for (int i = 0; i < 15; i++){ 

      LinearLayout linearLayout = new LinearLayout(this); 
      linearLayout.setOrientation(LinearLayout.HORIZONTAL); 

      ImageView imageView = new ImageView (this); 
      TextView textView = new TextView (this); 

      imageView.setImageResource(R.drawable.image); 
      textView.setText("Text View #" + i); 

      linearLayout.addView(imageView); 
      linearLayout.addView(textView); 

      topLinearLayout.addView(linearLayout);   

     } 

     scrollView.addView(topLinearLayout); 

    } 

您還可以定義在XML文件中的topLinearLayout對象。它是由你決定。
