Android Recognizer





範例程式碼

import........省略

public class MainActivity extends ActionBarActivity {

private static final String TAG = "SpeechRecognizerActivity";
    private TextView tv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.tv = (TextView) this.findViewById(R.id.tv);
    }

    public void onText(View v) {
        Intent it = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        it.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);

    }

    @Override

        }

    }

 
    //以下可省略
@Override

// Inflate the menu; this adds items to the action bar if it is present.

}

int id = item.getItemId();
if (id == R.id.action_settings) {

}

}

加入在:activity_main.xml


<Button
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:onClick="onText"
        android:text="語音辨識" />

<Button
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:onClick="onWeb"
        android:text="網頁搜尋" />

<ScrollView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >

<TextView
        android:id="@+id/tv"
        android:layout_width="fill_parent"/>


</ScrollView>



標記黃色區塊加入在:AndroidManifest.xml
可加可不加    要觸發onWeb(View v)才需要網路
