自定義EditTextPreference

Question

我需要在EditText裏面的EditText的右側添加一個麥克風圖像按鈕，所以當這個圖像按鈕被擊中時，識別器將被觸發以將語音轉換爲文本。

試試這個..

語音到文本

對於語音到文本你採取一些其他的例子......或者啓用脫機模式。

setOnTouchListener方法用於點擊你要採取正確的繪製

import android.app.Activity; 
    import android.content.ActivityNotFoundException; 
    import android.content.Intent; 
    import android.content.pm.PackageManager; 
    import android.content.pm.ResolveInfo; 
    import android.os.Bundle; 
    import android.speech.RecognizerIntent; 
    import android.view.MotionEvent; 
    import android.view.View; 
    import android.widget.EditText; 
    import android.widget.Toast; 

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


public class demon extends Activity { 


     EditText editComment; 
    private final int SPEECH_RECOGNITION_CODE = 1; 

     @Override 
     public void onCreate(Bundle icicle) { 
      super.onCreate(icicle); 
      setContentView(R.layout.demo); 
      editComment=(EditText) findViewById(R.id.edittext); 


      PackageManager pm = getPackageManager(); 
      List<ResolveInfo> activities = pm.queryIntentActivities(
        new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH), 0); 
      if (activities.size() == 0) 
      { 
       editComment.setEnabled(false); 
       editComment.setText("Recognizer not present"); 
      } 
      editComment.setOnTouchListener(new View.OnTouchListener() { 
       @Override 
       public boolean onTouch(View v, MotionEvent event) { 
        final int DRAWABLE_LEFT = 0; 
        final int DRAWABLE_TOP = 1; 
        final int DRAWABLE_RIGHT = 2; 
        final int DRAWABLE_BOTTOM = 3; 

        if(event.getAction() == MotionEvent.ACTION_UP) { 
         if(event.getRawX() >= (editComment.getRight() - editComment.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) { 
          // your action here 

          startSpeechToText(); 
          return true; 
         } 
        } 
        return false; 
       } 
      }); 


     } 


    private void startSpeechToText() { 
     Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); 
     intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault()); 
     intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, 
       RecognizerIntent.LANGUAGE_MODEL_FREE_FORM); 
     intent.putExtra(RecognizerIntent.EXTRA_PROMPT, 
       "Speak something..."); 
     try { 
      startActivityForResult(intent, SPEECH_RECOGNITION_CODE); 
     } catch (ActivityNotFoundException a) { 
      Toast.makeText(getApplicationContext(), 
        "Sorry! Speech recognition is not supported in this device.", 
        Toast.LENGTH_SHORT).show(); 
     } 
    } 
    /** 
    * Handle the results from the voice recognition activity. 
    */ 
    @Override 
    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
     super.onActivityResult(requestCode, resultCode, data); 
     switch (requestCode) { 
      case SPEECH_RECOGNITION_CODE: { 
       if (resultCode == RESULT_OK && null != data) { 
        ArrayList<String> result = data 
          .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS); 
        String text = result.get(0); 
        editComment.setText(text); 
       } 
       break; 
      } 
     } 
    } 
    } 

文本到語音

import android.view.MotionEvent; 
import android.view.View;

import android.widget.Toast; 

import java.util.Locale; 



public class demo extends Activity { 


    EditText editComment; 
    TextToSpeech t1; 
    @Override 
    public void onCreate(Bundle icicle) { 
     super.onCreate(icicle); 
     setContentView(R.layout.demo); 
     editComment=(EditText) findViewById(R.id.edittext); 
     editComment.setOnTouchListener(new View.OnTouchListener() { 
      @Override 
      public boolean onTouch(View v, MotionEvent event) { 
       final int DRAWABLE_LEFT = 0; 
       final int DRAWABLE_TOP = 1; 
       final int DRAWABLE_RIGHT = 2; 
       final int DRAWABLE_BOTTOM = 3; 

       if(event.getAction() == MotionEvent.ACTION_UP) { 
        if(event.getRawX() >= (editComment.getRight() - editComment.getCompoundDrawables()[DRAWABLE_RIGHT].getBounds().width())) { 
         // your action here 

         String toSpeak = editComment.getText().toString(); 
         Toast.makeText(getApplicationContext(), toSpeak,Toast.LENGTH_SHORT).show(); 
         t1.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null); 
         return true; 
        } 
       } 
       return false; 
      } 
     }); 
     t1=new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() { 
      @Override 
      public void onInit(int status) { 
       if(status != TextToSpeech.ERROR) { 
        t1.setLanguage(Locale.UK); 
       } 
      } 
     }); 

    } 

    public void onPause(){ 
     if(t1 !=null){ 
      t1.stop(); 
      t1.shutdown(); 
     } 
     super.onPause();
