我创建了两个活动：第一个包含工作机会的详细信息，下一个是对这份工作的假设。申请工作后，会出现一个警告对话框以确认操作成功。但是，此警报对话框出现在没有值的作业详细信息视图中！我该如何管理这个？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);
     ToggleButton precedent = (ToggleButton)findViewById(R.id.btn_preced);
     precedent.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent preced = new Intent(DetailsOffre.this,   Offres.class);
            startActivity(preced);
        }                   
     });
        Button postuler = (Button)findViewById(R.id.postuler);
         postuler.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                // TODO Auto-generated method stub
                TextView id_offre = (TextView) findViewById(R.id.tv_ID_Off1);

                SharedPreferences settings = getSharedPreferences(MY_PREFERENCES, 0);
                SharedPreferences.Editor editor = settings.edit();
                editor.putString("idoffre", id_offre.getText().toString());
                editor.commit();
                Intent intent_postul = new Intent(DetailsOffre.this,    Candidature.class);
                startActivity(intent_postul);
            }                   
         });
         Button enregistrer = (Button)findViewById(R.id.enregistrer);
         enregistrer.setOnClickListener(new View.OnClickListener(){
         public void onClick(View v) {
                // TODO Auto-generated method stub
                TextView id_offre = (TextView) findViewById(R.id.tv_ID_Off1);
                String idOf = id_offre.getText().toString();
                Intent intent_enregist = new Intent(DetailsOffre.this,  EnregistrerOffre.class);
                intent_enregist.putExtra("idoffre",idOf );
                startActivity(intent_enregist);
            }       
});

活动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());
}

    }

使用以下警报对话框。提供更多详细信息以了解您的要求。

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();

    }
