我尝试使用arraylist和简单的适配器向listview显示一些内容。我尝试了如下所示的方法,但结果显示了arraylist的姓氏。我不明白我的错是什么。
final ListView listView = (ListView) findViewById(R.id.mylist);
ArrayList<HashMap<String, String>> list_of_bookmarks = new ArrayList<HashMap<String, String>>();
HashMap<String, String> b = new HashMap<String, String>();
String[] from = { "php_key","c_key","android_key","hacking_key" };
String[] name_of_bookmarks = { "php","c","android","hacking" };
for(int i=0;i<4;i++)
{
b.put(from[i],name_of_bookmarks[i]);
list_of_bookmarks.add(b);
}
};
int[] to = { R.id.txt1,R.id.txt1,R.id.txt1,R.id.txt1};
SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), list_of_bookmarks, R.layout.list_layout, from, to);
listView.setAdapter(adapter);
我只想在列表视图中显示“ php”,“ c”,“ android”,“ hacking”。我应该是一个初学者,所以您可能会建议我应该遵循的更好的方法
Main.xml
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="60dp" >
<ListView
android:id="@+id/zone_list"
android:layout_marginBottom="70dp"
android:background="@drawable/batteryborder"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
</LinearLayout>
setlanguage.xml
<?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="60dp">
<TextView
android:id="@+id/tvName"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:textSize="18dp"
android:gravity="center_vertical" />
</LinearLayout>
添加您的活动文件的onCreate()
ListView listView;
String[] from = { "php_key","c_key","android_key","hacking_key" };
ArrayAdapter arrayAdapter;
listView = (ListView) findViewById(R.id.zone_list);
arrayAdapter = new ArrayAdapter<>(this,R.layout.setlanguage, R.id.tvName, from);
listView.setAdapter(arrayAdapter);
