我希望你能帮助我解决这个问题.谢谢。
这是您的解决方案。
首先将主活动列表视图.setOnItemClickListener=> onItemClick 方法替换为以下代码
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String stateName = listView.getAdapter().getItem(position).toString();
int pos=0;
for(int i=0;i<stateList.length;i++)
{
if(stateList[i].equals(stateName))
{
pos=i;
break;
}
}
// Put selected state to intent.
Intent intent = new Intent(MainActivity.this, NextActivity.class);
intent.putExtra("selectedState", stateName);
intent.putExtra("anotherStringArray", anotherStringArray[pos]);
startActivity(intent);
}
});
并且还要使您的stateList数组和另一个StringArray在string.xml文件中的大小相同。
<string-array name="stateList">
<item>Abstract Window Toolkit (AWT)</item>
<item>abstract</item>
<item>abstract class</item>
<item>abstract method</item>
<item>access control</item>
<item>ACID</item>
<item>activation</item>
<item>actual parameter list</item>
<item>alpha value</item>
</string-array>
<string-array name="anotherStringArray">
