如何在应用程序中显示“语音输入和输出”设置页面？

Answer 1

以下内容可在Android 2.3.3源代码git中找到：

 501         <activity android:name="VoiceInputOutputSettings"
 502                 android:label="@string/voice_input_output_settings">
 503             <intent-filter>
 504                 <action android:name="android.intent.action.MAIN" />
 505                 <action android:name="com.android.settings.VOICE_INPUT_OUTPUT_SETTINGS" />
 506                 <category android:name="android.intent.category.DEFAULT" />
 507             </intent-filter>
 508         </activity>
 509 
 510         <activity android:name="TextToSpeechSettings" android:label="@string/tts_settings">
 511             <intent-filter>
 512                 <action android:name="android.intent.action.MAIN" />
 513                 <action android:name="com.android.settings.TTS_SETTINGS" />
 514                 <category android:name="android.intent.category.DEFAULT" />
 515             </intent-filter>
 516         </activity>

这两项行动可能没有官方常数。但您可以尝试“com.android.settings.VOICE_INPUT_OUTPUT_SETTINGS”和“com.android.settings.TTS_SETTINGS”，它适用于我的Nexus S.

这是我使用Android 2.2

的代码

final Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setComponent(ComponentName.unflattenFromString("com.android.settings/.TextToSpeechSettings"));
intent.addCategory(Intent.CATEGORY_LAUNCHER );
startActivity(intent);

此代码适用于显示语音输入/输出设置页面。希望这对你有用。

Intent intent = new Intent(Intent.ACTION_MAIN);
intent.setComponent(new ComponentName("com.android.settings","com.android.settings.VoiceInputOutputSettings"));     
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
