builder.setView(view);
TextView tvIdiomInfo=(TextView) view.findViewById(R.id.tvIdiomInfo);
tvIdiomInfo.setText(result);
builder.setPositiveButton("确定", new OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {

3.修改StudyAnimalActivity的点击事件。

<span style="font-size:18px;">package com.example.happyidiom;

import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.AdapterView;

public class StudyAnimalActivity extends Activity {

private AnimalDao animalDao;
private ListView lvAnimalList;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_study_animal);
initAnimals();
lvAnimalList=(ListView) findViewById(R.id.lvAnimalList);
AnimalAdapter animalAdapter=new AnimalAdapter(this, R.layout.animal_item, animalList);
lvAnimalList.setAdapter(animalAdapter);
lvAnimalList.setOnItemClickListener(new OnItemClickListener() {

@Override
public void onItemClick(AdapterView<?> adapterView, View view, int position,
long id) {
// TODO Auto-generated method stub
Animal animal=animalList.get(position);
String result=animal.getName()+"\n"+
animal.getPronounce()+
"\n【解释】："+animal.getExplain()
+"\n【近义词】："+animal.getHomoionym()+
"\n【反义词】："+animal.getAutonym()+
"\n【来源】："+animal.getDerivation()+
"\n【示例】："+animal.getExamples();
DialogUtil.showDialog(result, StudyAnimalActivity.this);

}
});
}

private void initAnimals() {
// TODO Auto-generated method stub
animalDao=AnimalDao.getInstance(this);
animalList=animalDao.getAllAnimals();
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.study_animal, menu);
return true;
}

}</span>
