android - OnActivityResult 在同一 Activity 中处理不同的请求代码

Question

一直在尝试应用类似问题的一些解决方案，但到目前为止我没有运气。

我有一个带有两个按钮的 Activity ，每个按钮调用 RecognizerIntent 来进行一些语音识别。我试图让每个按钮调用自己的 RecognizerIntent 并在同一 Activity 中检查单独的 requestCode。

这是我目前所拥有的:

public class Cooking  extends Activity implements OnClickListener{

    ListView lv;
        static final int check = 111;
        static final int checka = 111;
        static final int checkb = 111;

    @Override
        protected void onCreate(Bundle savedInstanceState) {
            // TODO Auto-generated method stub
            super.onCreate(savedInstanceState);
            setContentView(R.layout.cooking);
              initialize();                 
    }        

    private void initialize() {
        // TODO Auto-generated method stub
        lv = (ListView)findViewById(R.id.lvVoiceReturn);

        display = (ImageView) findViewById(R.id.IVdisplay);
        ImageView image1 = (ImageView) findViewById(R.id.IVimage1);
        ImageView image2 = (ImageView) findViewById(R.id.IVimage2);

        image1.setOnClickListener(this);
        image2.setOnClickListener(this);

        ActionBar actionBar = getActionBar();
        actionBar.setDisplayHomeAsUpEnabled(false);     
    }



    @Override
    public void onClick(View v) {
        if(v.getId() == R.id.IVimage1){
            Intent a = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
            a.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, 
                       RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
            a.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1);
            a.putExtra(RecognizerIntent.EXTRA_PROMPT, "Speak.");
            startActivityForResult(a, checka);
        }else if(v.getId() == R.id.IVimage2){
            Intent b = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
            b.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                       RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
            b.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1);
            b.putExtra(RecognizerIntent.EXTRA_PROMPT, "Speak.");
            startActivityForResult(b, checkb);  
        }
    }

    @Override
    protected void onActivityResult(int requestCode, 
                                    int resultCode, 
                                    Intent data) {
        // TODO Auto-generated method stub
        if (requestCode == checka && resultCode == RESULT_OK){
            ArrayList<String> results = 
                data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
            lv.setAdapter(
                new ArrayAdapter<String>(this, 
                                         android.R.layout.simple_list_item_1,
                                         results));
            if(results.contains("really")
               || results.contains("yes really") 
               || results.contains("disease"))
            {                   
                /////toast referenced to xml the after 400ms
                counter_score ++ ;
                txView.setId(1);
                counter_score_z +=1;
                ourSong = MediaPlayer.create(Cooking.this, R.raw.rightsound2);
                ourSong.start();
                AlertDialog dialogBuilder = new AlertDialog.Builder(this).create();
                dialogBuilder.setTitle("Nice");
                dialogBuilder.setMessage("Correct!.");
                dialogBuilder.setIcon(R.drawable.ic_mark);
                dialogBuilder.show();

                Thread timer = new Thread(){

                            e.printStackTrace();
                        } finally {
                            Intent nextAct = new Intent(Cooking.this, LetterEx.class);
                            startActivity(nextAct);
                            finish();

                timer.start();

                   dialogBuilder.setButton2("try again", 
                                            new DialogInterface.OnClickListener() {

                        @Override

                            dialog.dismiss();
                        }
                    });
                    dialogBuilder.show();
                    Thread timer = new Thread(){
                        public void run(){
                            try{
                             sleep(4000);
                            }catch (InterruptedException e){
                                e.printStackTrace();
                            } finally {

                            }
                        }
                    };
                    timer.start();
                }
            }
            super.onActivityResult(requestCode, resultCode, data);  
        }
    }

这不会崩溃或发生任何事情，但它没有按照我的意愿去做。

当按钮(IVimage1)被按下时...

public void onClick(View v) {
     if(v.getId() == R.id.IVimage1){
        Intent a = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        a.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, 
                       RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        a.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1);
        a.putExtra(RecognizerIntent.EXTRA_PROMPT, "Speak.");
        startActivityForResult(a, checka);

正确检查了 checka 的 requestCode 并显示了“正确”对话框，但是也显示了“checkb”的错误对话框。很明显，我需要打破 If 语句代码......以分离请求代码并将一个分配给每个按钮。

我试过 break；返回;做开关()；和来自类似问题的案例，但到目前为止还没有运气......

您已定义它，使得 checka == checkb 始终。尝试给它们不同的值。

    // For example:
    static final int check = 111;
    static final int checka = 112;
    static final int checkb = 113;
