在我正在开发的 android 4.1 应用程序中，我希望搜索结果列表视图中的文本显示在缩略图的右侧。我通过解析 xml 文件得到结果。现在我的文字出现在图像下方，但我希望它出现在图像的右侧。

people_search_list.xml

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

    <ListView android:id="@android:id/list"
        android:layout_width="fill_parent" android:layout_height="0dip"
        android:layout_weight="1" android:drawSelectorOnTop="false"
        />

    <ImageView
        android:id="@+id/image"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:contentDescription="@string/description"
        android:gravity="left"
        android:scaleType="fitXY" />

        <TextView
        android:id="@+id/empty"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_gravity="left"
        android:text="" />

    <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="wrap_content">

    <LinearLayout
        android:id="@+id/footer"
        style="@android:style/ButtonBar"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal" >

        <Button
            android:id="@+id/prev_10_results"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="0.14"
            android:text="@string/prev_10_results" />

        <Button
            android:id="@+id/next_10_results"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="0.5"
            android:text="@string/next_10_results" />
    </LinearLayout>

    </ScrollView>

    </LinearLayout>

PeopleSearchAdapter.java（这是我从 xml 文件中获取内容后显示内容的地方）

    public PeopleListView (Context context, String itemName, String itemLocation, String image_url, String kudoRank)
        {
            super (context);
            setOrientation(LinearLayout.VERTICAL);

            LinearLayout.LayoutParams params = new  LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT);
            params.setMargins(5, 3, 5, 0);

            image = new ImageView (context);
            Log.v("Image URL: ", image_url);
            if(image_url != null && !(image_url.equals("")))
            {
                try
                {
                    URL url = new URL (image_url);
                    URLConnection conn = url.openConnection();
                    conn.connect();
                    BufferedInputStream bis = new BufferedInputStream(conn.getInputStream());
                    Bitmap bm = BitmapFactory.decodeStream (bis);
                    bis.close ();
                    image.setImageBitmap(bm);
                }
                catch (IOException e)
                {
                    e.printStackTrace();
                }
            }

            else
            {
                image.setImageResource(R.drawable.no_image);
            }
            addView (image, params);

            name = new TextView (context);
            name.setText(itemName);
            name.setTextSize(16f);
            name.setTextColor(Color.BLACK);
            addView(name, params);

            kudo_rank = new TextView (context);
            kudo_rank.setText(kudoRank);
            kudo_rank.setTextSize(16f);
            kudo_rank.setTextColor(Color.BLACK);
            addView(kudo_rank, params);

            location = new TextView (context);
            location.setText(itemLocation);
            location.setTextSize(16f);
            location.setTextColor(Color.BLACK);
            addView(location, params);

        }

I've attached a screenshot of how the results are being displayed now and just want the three text fields that are displayed below the image right now to be displayed to its right instead.

搜索结果视图

谢谢..

最简单的方法是在ListViewxml 中定义布局。这是我用的。我对应用程序做了类似的事情，希望对您有所帮助：

这是显示列表视图的位置：

  <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/view" >

    <LinearLayout
        android:id="@+id/linearLayout1"
        android:layout_width="fill_parent"
        android:layout_height="50dp"
        android:background="@drawable/logo"
        android:orientation="vertical" >
    </LinearLayout>

    <com.google.ads.AdView
            android:id="@+id/adView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentBottom="true"
            ads:adSize="BANNER"
            ads:adUnitId="a15009789e230a7" />
    <ListView
        android:id="@android:id/list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/linearLayout1"
        android:layout_above="@+id/adView"
        android:layout_centerHorizontal="true"
        android:background="@drawable/background"
        android:cacheColorHint="#00000000" >
    </ListView>






</RelativeLayout>

这是ListView定义的地方，其布局类似于您想要的：

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal"
    android:padding="10dp" >

    <ImageView
        android:id="@+id/imgThumb"
        android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:layout_alignParentBottom="true"
        android:layout_alignParentTop="true"
        android:layout_marginBottom="5dp"
        android:layout_marginRight="15dp"
        android:layout_marginTop="5dp"
        android:background="@drawable/diningbutton"
        android:gravity="center_vertical" />

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@+id/imgThumb"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/diningTitle"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_alignParentBottom="true"
            android:layout_alignParentTop="true"
            android:gravity="top"
            android:paddingTop="5dp"
            android:textColor="#000000"
            android:textSize="16dp"
            android:textStyle="normal" />

        <TextView
            android:id="@+id/listSubHeader"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:gravity="bottom"
            android:paddingBottom="5dp"
            android:paddingTop="5dp"
            android:textColor="#000000"
            android:textSize="14dp"
            android:textStyle="italic" />
    </LinearLayout>

</RelativeLayout>

这是适配器：

    @Override
protected void onCreate(Bundle savedInstanceState)
{

    super.onCreate(savedInstanceState);
    this.setContentView(R.layout.dining);



    // Create ListData object to hold list data
    ListData newListItem = new ListData();

    try
    {
        // parse data and populate the list view
        this.itemObject = newListItem.getData(DATAURL);
        Log.e(TAG, "item object: " + this.itemObject.toString());
        ListAdapter adapter = new ListAdapter(this, R.layout.dininglistview, this.itemObject);
        // Create listview
        this.listView1 = (ListView) this.findViewById(android.R.id.list);
        this.listView1.setAdapter(adapter);
        GetImagesTask imgTask = new GetImagesTask();
        imgTask.execute(this.itemObject);

        AdView adView = (AdView)this.findViewById(R.id.adView);
        AdRequest re = new AdRequest();
        adView.loadAd(re);

    }
    catch (InterruptedException e)
    {

        Log.e(TAG, "Unexpected error", e);
    }
    catch (ServiceException e)
    {
        AlertDialog alertDialog = new AlertDialog.Builder(DiningActivity.this).create();
        alertDialog.setTitle("Temporarily unavailable");
        alertDialog.setMessage("Please contact top25@uievolution.com");
        alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
            // if there is an error, send the user to the home page
            @Override
            public void onClick(DialogInterface dialog, int which)
            {
                Intent homeIntent = new Intent(DiningActivity.this, HomeActivity.class);
                DiningActivity.this.startActivity(homeIntent);

            }
        });
        alertDialog.show();
    }
    // implement dining adapter

}

我希望这有帮助！祝你好运！
