public class SpeakingActivity extends AppCompatActivity {
private static final int REQUEST_CODE_SPEECH_INPUT = 1000;
TextView mTextView;
TextView input;
ImageButton mImageButton;
Button button;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.speakingfromhome);
    button = findViewById(R.id.nextSpeaking);
    mTextView = findViewById(R.id.output);
    mImageButton = findViewById(R.id.image);
    input = findViewById(R.id.input);

    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            changeQuestions();
            mTextView.setTextColor(Color.BLACK);
        }
    });
    mImageButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            speak();
            checkIfCorrect();
        }

    });
}


private void checkIfCorrect() {
    if (input.toString().equals(mTextView.toString()))
        mTextView.setTextColor(Color.GREEN);
    else
        mTextView.setTextColor(Color.RED);
}

private void changeQuestions() {
    input.setText("基辅");
}

private void speak() {
    Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
    intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.CHINA.toString());
    try {
        startActivityForResult(intent, REQUEST_CODE_SPEECH_INPUT);

    } catch (Exception ex) {
        Toast.makeText(this, ""   ex.getMessage(), Toast.LENGTH_SHORT).show();
    }

}

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
        case REQUEST_CODE_SPEECH_INPUT: {
            if (resultCode == RESULT_OK && null != data) {
                ArrayList<String> result = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
                mTextView.setText(result.get(0));
            }
            break;
        }
    }
}

}

CodePudding user response：

The function checkIfCorrect() is the problem

Change it to:

input.toString() -> input.getText()
mTextView.toString() -> mTextView.getText()

Like:

input.getText().equals(mTextView.getText())

with getText() get the text of the TextView, doint input.toString() convert the object TextView to String

your checkIfCorrect function must look like:

private void checkIfCorrect() {
    if (input.getText().equals(mTextView.getText()))
        mTextView.setTextColor(Color.GREEN);
    else
        mTextView.setTextColor(Color.RED);
}

A better way:

private void checkIfCorrect() {
  mTextView.setTextColor((input.getText().equals(mTextView.getText())) ? Color.GREEN : Color.RED )
}
