自定义ListView Android

Question

我的自定义ListView有问题。

SimpleAdapter adapter = new SimpleAdapter(this,
  this.dh.selectAll(),
  R.layout.custom_row_view,
  new String[] {"Icon","Chance","TeamID"},
  new int[] {R.id.text1,R.id.text2, R.id.text3});
  setListAdapter(adapter);

这是我的简单适配器。我想把它们放进去，我可以这样做吗？

是的，你可以......

MyList.java：

package com.TestActivity;

import java.util.ArrayList;
import java.util.HashMap;

import android.app.ListActivity;
import android.os.Bundle;
import android.widget.SimpleAdapter;


public class MyList extends ListActivity {

    final static ArrayList<HashMap<String, ?>> data = new ArrayList<HashMap<String, ?>>();

    static{
        HashMap<String, Object> row  = new HashMap<String, Object>();
        row.put("Icon", R.drawable.flags_albania);
        row.put("Chance", "65%");
        row.put("TeamID", "Albania");
        data.add(row);
        row  = new HashMap<String, Object>();
        row.put("Icon", R.drawable.flags_rpa);
        row.put("Chance", "55%");
        row.put("TeamID", "RPA");
        data.add(row);
        row  = new HashMap<String, Object>();
        row.put("Icon", R.drawable.flags_polska);
        row.put("Chance", "100%");
        row.put("TeamID", "Polska :)");
        data.add(row);
    }
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        SimpleAdapter adapter = new SimpleAdapter(this,
                data,
                  R.layout.row,
                  new String[] {"Icon","Chance","TeamID"},
                  new int[] { R.id.imageView1, R.id.textView1,R.id.textView2});
       setListAdapter(adapter);

    }
}

RES /布局/ row.xml：

<?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">
    <ImageView android:layout_height="wrap_content" android:layout_width="wrap_content" android:src="@drawable/icon" android:id="@+id/imageView1"/>
    <TextView android:text="TextView" android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content"/>
    <TextView android:text="TextView" android:id="@+id/textView2" android:layout_width="wrap_content" android:layout_height="wrap_content"/>
</LinearLayout>

将带有标志的pngs放到res / drawable-hdpi /

flags_albania.png flags_rpa.png flags_polska.png

你会得到这样的东西：
