我需要提取联系人详细信息，当我提取详细信息时，我需要在Loading...中显示Progress Dialog Box。我的应用程序在Android 2.3.6中运行良好，但它在Android 4.1.2及更高版本中崩溃。
请帮帮我

答案 0 :(得分：1)
for progress Dialog 修改AsyncTask ，如下所示：
private class FetchContacts extends AsyncTask<String, String, String> {
@Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
progressDialog.setMessage("Loading...");
progressDialog.show();
mHandler.sendEmptyMessage(0);
}
@Override
protected String doInBackground(String... params) {
// TODO Auto-generated method stub
fetchContacts();
return "";
}
@Override
protected void onPostExecute(String result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
mHandler.sendEmptyMessage(1);
mAdapter.notifyDataSetChanged();
progressDialog.dismiss();
}
}
删除这段代码：
private Handler mHandler = new Handler(){
public void handleMessage(Message msg)
{
switch(msg.what){
case 0:{
showProgressDialog();
}
break;
case 1:{
dismissProgressDialog();
}
break;
}
}
};
private void showProgressDialog() {
if(progressDialog != null) {
progressDialog.setMessage("Loading...");
progressDialog.show();
}
}
private void dismissProgressDialog() {
if(progressDialog != null)
progressDialog.dismiss();
}
