Question

我正在开发一个Android应用程序，可以使用Google的API进行语音输入和转换为文本，然后将文本放入文本字段。并且可以使用按钮发送该文本。现在出现的问题是，当出现SpeechInput对话框并且在进行语音输入之后，应用程序关闭，这不会将转换的语音放入Edittext字段。该应用程序刚关闭。什么问题，任何帮助将不胜感激。这是我的源代码片段：

public class MainActivity extends AppCompatActivity {

    TextView tr;
    ImageButton m;
    String x;
    EditText i;

    private static int SIGN_IN_REQUEST_CODE = 1;
    FirebaseListAdapter<ChatMessage> adapter;
    RelativeLayout activity_main;
    FloatingActionButton fab;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        activity_main = findViewById(R.id.activity_main);
        fab = (FloatingActionButton) findViewById(R.id.fab);
        //m = (ImageButton) findViewById(R.id.imageButton3);
        i = (EditText) findViewById(R.id.getSpeechInput);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                getSpeechInput();
                i.setText(x, TextView.BufferType.EDITABLE);
                FirebaseDatabase.getInstance().getReference().push().setValue(new ChatMessage(i.getText().toString(), FirebaseAuth.getInstance().getCurrentUser().getEmail()));
                i.setText("");
            }
        });
        if (FirebaseAuth.getInstance().getCurrentUser() == null) {
            startActivityForResult(AuthUI.getInstance().createSignInIntentBuilder().build(), SIGN_IN_REQUEST_CODE);
        } else {
            Snackbar.make(activity_main, "Welcome " + FirebaseAuth.getInstance().getCurrentUser().getEmail(), Snackbar.LENGTH_LONG).show();
            displayChatMessage();
        }
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item.getItemId() == R.id.menu_sign_out) {
            AuthUI.getInstance().signOut(this).addOnCompleteListener(new OnCompleteListener<Void>() {
                @Override
                public void onComplete(@NonNull Task<Void> task) {
                    Snackbar.make(activity_main, "You have been signed out..", Snackbar.LENGTH_SHORT).show();
                    finish();
                }
            });
        }
        return true;
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main_menu, menu);
        return true;
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == SIGN_IN_REQUEST_CODE) {
            Snackbar.make(activity_main, "Sussesfully Signed in.Welcome!!", Snackbar.LENGTH_SHORT).show();
            displayChatMessage();
        } else {
            Snackbar.make(activity_main, "We could not Sign in", Snackbar.LENGTH_SHORT).show();
            finish();
        }
    }

    private void displayChatMessage() {
        ListView l = (ListView) findViewById(R.id.list_of_massage);
        adapter = new FirebaseListAdapter<ChatMessage>(this, ChatMessage.class, R.layout.list_item, FirebaseDatabase.getInstance().getReference()) {
            @Override
            protected void populateView(View v, ChatMessage model, int position) {
                TextView m1, m2, m3;
                m1 = (TextView) v.findViewById(R.id.message_text);
                m2 = (TextView) v.findViewById(R.id.message_user);
                m3 = (TextView) v.findViewById(R.id.message_time);
                m1.setText(model.getMessageText());
                m2.setText(model.getMessageUser());
                m3.setText(DateFormat.format("dd-MM-YYYY(HH:mm:ss)", model.getMessageTime()));

            }
        };
        l.setAdapter(adapter);
    }

    /*private void displayChatMassage(){

    }*/
    public void getSpeechInput() {
        Intent i = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        i.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
        if (i.resolveActivity(getPackageManager()) != null) {
            startActivityForResult(i, 10);
        } else {
            Toast.makeText(getApplicationContext(), "Input is not supported in the device", Toast.LENGTH_LONG).show();
        }
    }
}

您的onActivityResult()方法无法区分从不同活动收到的结果。您（至少）有两个地方可以启动单独的活动并期望获得结果：当您使用onCreate()的请求代码和SIGN_IN_REQUEST_CODE尝试使用Firebase登录时getSpeechInput()当您使用请求代码10启动语音识别活动时。特别是，只要结果代码（而非请求代码）不是finish()，您就会调用SIGN_IN_REQUEST_CODE。（请注意，RESULT_OK（通常用于表示成功的结果代码）的值为-1。）

尝试这样的事情：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == SIGN_IN_REQUEST_CODE) { // NOT resultCode
        if (resultCode == RESULT_OK) {
            Snackbar.make(activity_main, "Sussesfully Signed in.Welcome!!", Snackbar.LENGTH_SHORT).show();
            displayChatMessage();
        } else {
            Snackbar.make(activity_main, "We could not Sign in", Snackbar.LENGTH_SHORT).show();
            finish();
        }
    } else if (requestCode == 10) {
        // process result of speech recognition activity
    }
}
