在android中的语音识别后，文本不会在editText上打印

Question

在运行时，语音识别意图启动，但它不会在EditText上打印任何内容

以下是代码：

import android.app.Activity;
import android.content.ActivityNotFoundException;
import android.content.Intent;
import android.speech.RecognizerIntent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.ImageButton;
import android.widget.Toast;

import java.util.ArrayList;
import java.util.List;
import java.util.Locale;

public class dialog1cl extends AppCompatActivity {
 public EditText ed;
    private static final int av= 0;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.dialog1);
        ed=(EditText)findViewById(R.id.editText);
        ImageButton im=(ImageButton)findViewById(R.id.imageButton);
        im.setOnClickListener(new View.OnClickListener(){
            public void onClick(View view){

                promptspeech();
            }
        });

    }
   public void promptspeech()
    {
        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());
        i.putExtra(RecognizerIntent.EXTRA_PROMPT,"Say Something!");

        try {
            startActivityForResult(i,av );
        }
        catch(ActivityNotFoundException a)
        {
            Toast.makeText(dialog1cl.this,"Sorry! Your device doesnt support speech Language",Toast.LENGTH_LONG).show();
        }
    }

    public void onActivityResult(int request_code , int result_code, Intent i){



             if(request_code ==av && result_code==RESULT_OK)
             {
                List<String> result=i.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
ed.setText(result.get(0));
            }
        super.onActivityResult(request_code, result_code, i);

    }
}

通过此更改活动结果，您必须以编程方式将文本设置为编辑文本

public void onActivityResult(int request_code , int result_code, Intent i){
         if(request_code ==av && result_code==RESULT_OK)
         {
            List<String> result=i.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

                ed.setText(result.get(0));
        }
    super.onActivityResult(request_code, result_code, i);

}

使用这个官方教程我得到了一个动作栏。 在创建可搜索和元数据时要格外小心。 https://developer.android.com/training/search/setup.html

如果您希望在同一活动中显示文本结果，请将Search Intent Filter指向当前活动，并将该活动singleTop singleInstance或singleTop 。

嘿，我为这样的错误道歉..但是我意识到代码是正确的，但我在xml文件中为表格布局做了我的背景白色，因此无法意识到它已经在编辑文本上打印了.. ..Ofcourse一个罕见的错误...希望它帮助那里的人..上面的代码适用于语音识别...从xml中排除以下部分：

background:"@colors/white"

Answer 4

您需要获取从活动中获得的结果并将EditText的文本设置为等于它。

List<String> result=i.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
String text = getTextFromResult(result);
ed.setText(text);
