运行时,语音识别意图启动,但它不会在EditText
上打印任何内容
下面是代码:
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);
}
}

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,我让它适用于操作栏。创建可搜索数据和元数据时要格外小心。https://developer.android.com/training/search/setup.html
如果要显示同一活动中的文本结果,请将Search Intent Filter
指向当前活动,并使该活动singleInstance
或singleTop
。
嘿,人们,我为这样的错误道歉。但是意识到代码是正确的,但我在表格布局的XML文件中将背景设置为白色,因此无法意识到它一直在编辑文本上打印....当然是一个罕见的错误...希望它能帮助那里的人。上面的代码适用于语音识别...从 XML 中排除以下部分:
background:"@colors/white"
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);
