如何在整个屏幕上制作语音识别器rwork

Question

我正在为视障人士制作应用程序，为此我希望每当用户触摸屏幕上的任何位置时，语音识别器应该启动。

我已经做语音识别等things..but我不能让我的语音识别器对TouchListener工作...

TouchListener不是借活动为视图。应用程序崩溃

完整代码如下。

public class MainActivity extends Activity 
{ 

private static final int REQUEST_CODE = 1234; 
private ListView wordsList; 
protected Button TextToSpeech; 
/** 
* Called with the activity is first created. 
*/ 
@Override 
public void onCreate(Bundle savedInstanceState) 
{ 
requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); 
super.onCreate(savedInstanceState); 
setContentView(R.layout.voice_recog); 
Button speakButton = (Button) findViewById(R.id.speakButton); 
Context context; 
context = this.getApplicationContext(); 
Intent Inte = new Intent(context, FallDetection.class); 
context.startService(Inte); 
Intent Inte1 = new Intent(context, SmsSpeaker.class); 
context.startService(Inte1); 
Toast toast = Toast.makeText(getApplicationContext(), "Fall Detection Started", Toast.LENGTH_LONG); 
toast.show(); 

wordsList = (ListView) findViewById(R.id.list); 
LinearLayout myScreen = (LinearLayout) findViewById(R.id.myscreen); 
// change LinearLayout to your framelayout if it is not a LinearLayout 
//View view =(View) findViewById(R.layout.voice_recog); 

//wordsList.setOnTouchListener(new View.OnTouchListener() { 
myScreen.setOnClickListener(new OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     // TODO Auto-generated method stub 
     Toast toast = Toast.makeText(getApplicationContext(),"Touch recognised",Toast.LENGTH_LONG); 
     toast.show(); 
     startVoiceRecognitionActivity(); 
    } 
}); 

截至目前我使用清单recignizing联系，但与来源，也是崩溃的应用程序未发现异常

布局XML文件如下

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/myscreen" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:orientation="vertical">
