Question

我是Android Studio的新手。我尝试用一种编辑文本尝试“语音转换为文本”，并且效果很好。但是我想用一个按钮将语音应用于文本以编辑两个文本。有人可以帮我吗？我尝试了其他资源，但是没有用。

 <EditText
        android:id="@+id/txt"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="phone"
        android:hint="phone"
        android:ems="10" />

    <EditText
        android:id="@+id/editText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="text"
        android:ems="10"
        android:inputType="text" />

    <Button
        android:id="@+id/button3"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Button" />

这是我要通过单个按钮和两个编辑文本将语音应用于文本的Java代码。单击该按钮时，它应该向下滚动到下一个编辑文本并接受输入

public class MainActivity extends AppCompatActivity {
        EditText tv1;
        EditText tv2;
        Button btn;
        private static final int REQUEST_CODE_SPEECH_INPUT = 1000;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            tv1 = findViewById(R.id.txt);
            tv2=findViewById(R.id.editText);
            btn = findViewById(R.id.button3);
            btn.setOnClickListener(new View.OnClickListener() {
                @Override 
                public void onClick(View v) {
                    speak();
                }

                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.getDefault());
                    intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "say something");

                    try {
                        startActivityForResult(intent, REQUEST_CODE_SPEECH_INPUT);

                    } catch (Exception e) {
                        ///Toast.makeText(this,"",Toast.LENGTH_SHORT).show();

                    }
                }

            });
        }
        @Override
        protected void onActivityResult(int requestCode, int resultCode, 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);
                        tv1.setText(result.get(0));
                    }
                    break;
                }

            }
        }
    }

Answer 2

onCreate之前：

private boolean isFirst=true;

在onActivityResult内部：

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        switch (requestCode) {
            case REQUEST_CODE_SPEECH_INPUT: {
                if (resultCode == RESULT_OK && null != data) {
                    if(isFirst){
                    isFirst=false;
                    ArrayList<String> result = data
                            .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
                    tv1.setText(result.get(0));
                    //startAnother ActivityFor Result here but getting the second edittext
                   }else{
isFirst=true; 
}
            }
            break;
        }

        }
    }
