小工具，电话语音识别应用程序

问题描述

我想创建一个包含一个ImageView的，点击后，启动语音识别应用程序中的小部件。我没有使用过的部件和正在申请的意图，所以我很困惑：如何创建一个未决的意图启动语音识别活性

我试着用这样的事情，但当然，失败：

   意向意图=新的意图（）;
   意图voiceIntent =新的意图（RecognizerIntent.ACTION_RECOGNIZE_SPEECH）;
   voiceIntent.putExtra（RecognizerIntent.EXTRA_LANGUAGE_MODEL，
     RecognizerIntent.LANGUAGE_MODEL_FREE_FORM）;
   voiceIntent.putExtra（RecognizerIntent.EXTRA_PROMPT，
     语音识别演示）;
   voiceIntent.setFlags（Intent.FLAG_ACTIVITY_NEW_TASK）;
   intent.putExtra（RecognizerIntent.EXTRA_RESULTS_PENDINGINTENT，voiceIntent）;
   PendingIntent pendingIntent = PendingIntent.getActivity（上下文，0，
     意图，0）;
   RemoteViews意见=新RemoteViews（context.getPackageName（）
     R.layout.main）;
   views.setOnClickPendingIntent（R.id.button，pendingIntent）;

解决方案

我知道了！我需要裹着的两个挂单意图两个经常意图，像这样的：

  //这个意图指向的活动，应该处理结果
意图activityIntent =新的意图（背景下，ResultsActivity.class）;
//这个意图包装效果的活动意图
PendingIntent resultsPendingIntent = PendingIntent.getActivity（上下文，0，activityIntent，0）;

//这个意图调用语音识别
意图voiceIntent =新的意图（RecognizerIntent.ACTION_RECOGNIZE_SPEECH）;
voiceIntent.putExtra（RecognizerIntent.EXTRA_LANGUAGE_MODEL，RecognizerIntent.LANGUAGE_MODEL_FREE_FORM）;
voiceIntent.putExtra（RecognizerIntent.EXTRA_PROMPT，语音识别演示）;
voiceIntent.setFlags（Intent.FLAG_ACTIVITY_NEW_TASK）;
voiceIntent.putExtra（RecognizerIntent.EXTRA_RESULTS_PENDINGINTENT，resultsPendingIntent）;

//这个意图包装语音识别意图
PendingIntent pendingIntent = PendingIntent.getActivity（上下文，0，voiceIntent，0）;
rv.setOnClickPendingIntent（R.id.btn，pendingIntent）;
 

I'm trying to create a widget that contains a single ImageView which, when clicked, starts speech recognition application. I've never worked with widgets and pending intents, so I'm confused: how to create a pending intent for starting speech recognition activity?

I tried with something like this, but it, of course, fails:

   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);

解决方案

I got it! I needed two regular intents wrapped in two pending intents, like this:

// 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);
