我创建了两个活动：第一个活动包含工作机会的详细信息，下一个活动是假设这个工作。申请工作后，会出现警告对话以确认操作是否成功。但是，此警报对话框中显示的作业详细信息没有值！ 我怎么能管理这个？ 这是活动1：
private static final String MY_PREFERENCES = "mespreferences";
TextView txt;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.detail_offre);

startActivity(preced);
}
});

活性2：
private static final String MY_PREFERENCES = "mespreferences";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.detail_offre);
SharedPreferences sharedPreferences = getSharedPreferences(MY_PREFERENCES, 0);
String userId = sharedPreferences.getString("id", "");
String idoffr = sharedPreferences.getString("idoffre", "");
Intent intent_postul = getIntent();
ArrayList<NameValuePair> postCandidature= new ArrayList<NameValuePair>();
postCandidature.add(new BasicNameValuePair("idoffre", idoffr));
postCandidature.add(new BasicNameValuePair("id", userId));
this.sendData(postCandidature);
}
private void sendData(ArrayList<NameValuePair> postCandidature) {
// TODO Auto-generated method stub
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://10.0.2.2/mesRequetes/candidature.php");
httppost.setEntity(new UrlEncodedFormEntity(postCandidature));
HttpResponse response = httpclient.execute(httppost);
Log.i("postData", response.getStatusLine().toString());
AlertDialog.Builder cand = new AlertDialog.Builder(Candidature.this);
cand.setIcon(R.drawable.succes);
cand.setTitle("Succès");
cand.setMessage("Votre candidature a bien été transmise");
cand.setPositiveButton("OK", new DialogInterface.OnClickListener(){
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Intent offr = new Intent (Candidature.this, Offres.class);
startActivity(offr);
}});
cand.show();
}catch(Exception e){
Log.e("log_tag", "Error in http connection " + e.toString());
}
}
答案 0 :(得分：0)
对警报对话框使用以下内容。提供更多细节以了解您的要求。
public void Alert(String text, String title)
{
AlertDialog dialog=new AlertDialog.Builder(context).create();
dialog.setTitle(title);
dialog.setMessage(text);
if(!title.equals("") && !text.equals(""))
{
dialog.setButton("OK",
new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int whichButton)
{
//
}
});
dialog.setButton2("Cancel",
new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int whichButton)
{
//
}
});
}
dialog.show();
}
