今天遇到一个令人头疼的问题：我在Activity中的onCreate（）方法中写了listView.setOnItemClickListener（）
但是运行模拟器后点击ListView的Item时没有任何反应，以前这样写却不会出现这种情况，
后来百度多次才找到问题所在：（参考链接：http://ming.highgic.com/?p=198）
原来这个ListView的item里面有button，需要在xml布局文件中设置button属性，其中focusable是关键：
android:focusable=”false”android:clickable=”false”
android:focusableInTouchMode=”false”
下面晒晒代码：
//Activity的onCreate（）方法
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.allcourses);
listView = (ListView) this.findViewById(R.id.allCourseListV);
mAdapter = new SimpleAdapter(this, getData(),
R.layout.allcourselistviewitem,
new String[] { "image",
"title", "tvgo" }, new int[] {
R.id.allCourseimageV,
R.id.allCoursetextextV, R.id.allCourseGo
});
listView.setAdapter(mAdapter);
listView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent,
View view,
int position, long id) {
Intent intent = new Intent(AllCourseActivity.this,
ClassificationCourseActivity.class);
String[] name = { "文学",
"哲学", "艺术", "历史", "经济", "教育", "生理学",
"农学", "法学", "心理学", "医学", "军事", "管理学",
"建筑与工程", "互联网" };
intent.putExtra("textViewName", name[position]);
startActivity(intent);
.show();
}
});
}
//上面SimpleAdapter需要绑定的数据
public List<HashMap<String, Object>> getData() {
mHashMaps = new ArrayList<HashMap<String, Object>>();
map = new HashMap<String, Object>();
map.put("image",
R.drawable.wx);
map.put("title", "文学");
mHashMaps.add(map);
map = new HashMap<String, Object>();
map.put("image",
R.drawable.zx);
map.put("title", "哲学");
mHashMaps.add(map);
map = new HashMap<String, Object>();
map.put("image",
R.drawable.ys);
map.put("title", "艺术");
mHashMaps.add(map);
map = new HashMap<String, Object>();
map.put("image",
R.drawable.ls);
map.put("title", "历史");
mHashMaps.add(map);
map = new HashMap<String, Object>();
map.put("image",
R.drawable.jjx);
map.put("title", "经济");
mHashMaps.add(map);
map = new HashMap<String, Object>();
map.put("image",
R.drawable.jyx);
map.put("title", "教育");
mHashMaps.add(map);
map = new HashMap<String, Object>();
map.put("image",
R.drawable.lk);
map.put("title", "生理学");
mHashMaps.add(map);
map = new HashMap<String, Object>();
map.put("image",
R.drawable.lx);
map.put("title", "农学");
mHashMaps.add(map);
map = new HashMap<String, Object>();
map.put("image",
R.drawable.fx);
map.put("title", "法学");
mHashMaps.add(map);
map = new HashMap<String, Object>();
map.put("image",
R.drawable.xlx);
map.put("title", "心理学");
mHashMaps.add(map);
map = new HashMap<String, Object>();
map.put("image",
R.drawable.yx);
map.put("title", "医学");
mHashMaps.add(map);
map = new HashMap<String, Object>();
map.put("image",
R.drawable.js);
map.put("title", "军事");
mHashMaps.add(map);
map = new HashMap<String, Object>();
map.put("image",
R.drawable.glx);
map.put("title", "管理学");
mHashMaps.add(map);
map = new HashMap<String, Object>();
map.put("image",
R.drawable.gk);
map.put("title", "建筑与工程");
mHashMaps.add(map);
map = new HashMap<String, Object>();
map.put("image",
R.drawable.jh);
map.put("title", "互联网");
mHashMaps.add(map);
return mHashMaps;
}
