调用语音识别应用程序的小部件
我正在尝试创建一个包含单个ImageView的小部件，点击该小部件可以启动语音识别应用程序。 我从来没有与小部件和待处理意图合作，所以我很困惑：如何创建启动语音识别活动的待定意图？
我尝试过这样的事情，但它当然失败了：
Intent intent = new Intent();
Intent voiceIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
voiceIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
voiceIntent.putExtra(RecognizerIntent.EXTRA_PROMPT,
"Speech recognition demo");
voiceIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra(RecognizerIntent.EXTRA_RESULTS_PENDINGINTENT, voiceIntent);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0,
intent, 0);
RemoteViews views = new RemoteViews(context.getPackageName(),
R.layout.main);
views.setOnClickPendingIntent(R.id.button, pendingIntent);
我知道了！ 我需要两个包含两个待定意图的常规意图，如下所示：
// this intent points to activity that should handle results
Intent activityIntent = new Intent(context, ResultsActivity.class);
// this intent wraps results activity intent
PendingIntent resultsPendingIntent = PendingIntent.getActivity(context, 0, activityIntent, 0);
// this intent calls the speech recognition
Intent voiceIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
voiceIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
voiceIntent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Speech recognition demo");
voiceIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
voiceIntent.putExtra(RecognizerIntent.EXTRA_RESULTS_PENDINGINTENT, resultsPendingIntent);
// this intent wraps voice recognition intent
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, voiceIntent, 0);
rv.setOnClickPendingIntent(R.id.btn, pendingIntent);
我也遇到同样的问题。
对不起，我没有足够的声望发表评论。
没有必要使用透明的活动来发送识别意图。
就像zorglub76的回答一样
Intent voiceIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
voiceIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
voiceIntent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Speech recognition demo");
voiceIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
voiceIntent.putExtra(RecognizerIntent.EXTRA_RESULTS_PENDINGINTENT, resultsPendingIntent);
识别结果将只是在的额外resultingPendingIntent
所以你需要做的是：
在ResultsActivity.onCreate()
ArrayList<String> voiceResults = this.getIntent().getExtras().getStringArrayList(RecognizerIntent.EXTRA_RESULTS);
注意NullPointerException ，你会从ArrayList中得到结果！
我想创建谷歌像小部件。 我尝试了zorglub76解决方案，但我无法得到结果的声音...
我通过创建一个虚拟transparrent活动来处理语音识别端到端来解决这个问题。
它的工作方式如下：Widget-> VoiceRecognitionStarterActivity-> RecognizerIntent-> VoiceRecognitionStarterActivity.onActivityResult。
我的小部件类：
public class MyWidgetProvider extends AppWidgetProvider {
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,int[] appWidgetIds) {
// Get all ids
ComponentName thisWidget = new ComponentName(context, MyWidgetProvider.class);
int[] allWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget);
for (int widgetId : allWidgetIds) {
RemoteViews remoteViews = new RemoteViews(context.getPackageName(), R.layout.widget_layout);
Intent activityIntent = new Intent(context, VoiceRecognitionStarterActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, activityIntent, 0);
remoteViews.setOnClickPendingIntent(R.id.mic_image, pendingIntent);
activityIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(context.getString(R.string.search_url)));
pendingIntent = PendingIntent.getActivity(context, 0, activityIntent, 0);
remoteViews.setOnClickPendingIntent(R.id.search_box_image, pendingIntent);
appWidgetManager.updateAppWidget(widgetId, remoteViews);
}
}
}
我的透明活动：
public class VoiceRecognitionStarterActivity extends Activity
{
private static final String TAG = "VoiceRecognitionStarterActivity";
private int SPEECH_REQUEST_CODE = 1;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
sendRecognizeIntent();
}
private void sendRecognizeIntent()
{
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "Speak to search");
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 10);
startActivityForResult(intent, SPEECH_REQUEST_CODE);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (requestCode == SPEECH_REQUEST_CODE)
{
if (resultCode == RESULT_OK) {
Log.d(TAG, "result ok");
Intent searchIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(getString(R.string.search_url)));
startActivity(searchIntent);
finish();
} else {
Log.d(TAG, "result NOT ok");
finish();
}
}
super.onActivityResult(requestCode, resultCode, data);
}
}
