Android - LazyAdapter 重叠 View

Question

我正在执行延迟加载以显示图像和文本。我现在已经准备好了一切，试图在 View 中添加一个 TextView 。但是，我的适配器与我的 View 重叠。更简单的说法是， ListView 与 TextView 重叠。我不确定我哪里做错了，因为 original example能够在 ListView 下方显示一个按钮，但我没有。我没有收到任何错误。我的 ListView 只覆盖了整个屏幕。知道可能是什么问题吗？

主.java

public class main extends Activity {

private static final String targetURL ="http://www.google.com/images";
ListView list;

ProgressDialog dialog;
private String[] mStrings = {};
private String[] dStrings = {};
//TextView tv;

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);         
    new TheTask().execute();
    list=(ListView)findViewById(R.id.list);
    TextView tv = (TextView)findViewById(R.id.tv);

    //tv.setText("Text View is displayed");
}   


protected class TheTask extends AsyncTask<Void, Void, MyResultClass >{

    protected void onPreExecute() {
        dialog = ProgressDialog.show(Cats.this, "Retrieving Information", "Please wait for few seconds...", true, false);
        dialog.setCancelable(true);
    }

    protected MyResultClass doInBackground(Void... params) {
        searchContent();
        MyResultClass result = new MyResultClass();
        result.mStrings = mStrings;
        result.dStrings = dStrings;
        return result;
    }   

    protected void onPostExecute(MyResultClass result) {            
        dStrings = result.dStrings;
        mStrings = result.mStrings;         
        LazyAdapter adapter = new LazyAdapter(Cats.this, mStrings, dStrings);
        list.setAdapter(adapter);
        dialog.dismiss();
    }       
}

    class MyResultClass
    { 
        public String[] mStrings; 
        public String[] dStrings; 
    }

public void searchContent()
{
    String imageC = "";
    String textC = "";

    try {

        URL url = new URL(targetURL);

        // Make the connection
        URLConnection conn = url.openConnection();
        BufferedReader reader = new BufferedReader(
         new InputStreamReader(conn.getInputStream()));

        String line = reader.readLine();
        Pattern sChar = Pattern.compile("&.*?;");
        line.replaceAll("\\<.*?\\>", "");
        Matcher msChar = sChar.matcher(line);
        while (msChar.find()) line = msChar.replaceAll("");

        while (line != null) {

            if(line.contains("../../"))
            {

                int startIndex = line.indexOf("../../") + 6;
                int endIndex = line.indexOf(">", startIndex + 1);
                String abc = "http://www.google.com/";
                String imageSrc = line.substring(startIndex,endIndex);
                //complete full url
                String xyz = abc +imageSrc;
                xyz = xyz.substring(0,xyz.indexOf('"'));
                xyz = xyz +";";
                xyz = xyz.replaceAll(" ", "%20");
                imageC += xyz;                  
                mStrings = imageC.split(";");
                line = reader.readLine();
            }

            if(line.contains("../../") == false)
            {
                line = reader.readLine();
            }

            if (line.contains("Gnametag"))
            {
                int startIndex = line.indexOf("Gnametag") + 10;
                int endIndex = line.indexOf("<", startIndex + 1);
                String gname = line.substring(startIndex,endIndex);
                textC = textC.replaceAll("</span>", "");
                textC += "Name: "+gname+ "\n";
            }

                if (line.contains("Age"))
                {
                    textC += "Age: "+reader.readLine() + "\n" + ";";
                    textC = textC.replaceAll("                  ", "");
                    dStrings = textC.split(";");
                }

            if (line.contains("Last Update"))
            {
                reader.close();
            }                               
        }           

        // Close the reader
        reader.close();

    } catch (Exception ex) {
        ex.printStackTrace();           
    }     

}
}

适配器.java

public View getView(int position, View convertView, ViewGroup parent) {
    View vi=convertView;
    ViewHolder holder;
    if(convertView==null){
        vi = inflater.inflate(R.layout.item, null);
        holder=new ViewHolder();
        holder.text=(TextView)vi.findViewById(R.id.text);;
        holder.image=(ImageView)vi.findViewById(R.id.image);
        vi.setTag(holder);
    }
    else
        holder=(ViewHolder)vi.getTag();

    holder.text.setText(text[position]);
    holder.image.setTag(data[position]);
    imageLoader.DisplayImage(data[position], activity, holder.image);
    return vi;
}

item.xml(Adapter.java 使用)

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#FFFFFF">
<ImageView
  android:id="@+id/image"
  android:layout_width="90dip"
  android:layout_height="90dip" 
  android:src="@drawable/stub" 
  android:scaleType="centerCrop"
  android:layout_gravity="left|center_vertical" 
  />

<TextView
  android:id="@+id/text"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:gravity="center"
  android:textSize="15dip"/>

</LinearLayout>

主.xml

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#FFFFFF">

<LinearLayout
android:id="@+id/linear1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#FFFFFF">

<TextView
android:id="@+id/tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Testing 123"
/> 

</LinearLayout>

<LinearLayout
android:id="@+id/linear2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"    
android:layout_below="@+id/linear1"
android:background="#FFFFFF">

<ListView
android:id="@+id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="30dp"/>
</LinearLayout>

</RelativeLayout>

Answer 1

只需从这一行中删除 + 符号

android:layout_below="@+id/linear1"

在第二个线性布局节中。
