Question

I am working on an android application in which i have implemented voice recognition and TTS. So i was thinking to launch settings screen for both google voice recognition and TTS to allow user to change settings from within the application. I have implemented TTS settings successfully by using following code:

intent = new Intent();
intent.setAction("com.android.settings.TTS_SETTINGS");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
this.startActivity(intent);

Now I want to show system s "google voice recognition settings" in my application to allow user to change language options etc. I have searched a lot... Done a lot of hit and try but failed to load voice recognition settings screen. Please tell me how i can implement that. Thanks in advance...

Answer 1

I was stuck on this for ages too...

    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.setComponent(newComponentName("com.google.android.voicesearch","com.google.android.voicesearch.VoiceSearchPreferences"));
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    this.startActivity(intent);
    }

Hope it does for you too...

EDIT:正如在评论中指出的,谷歌搜索应用的Jelly Bean版本已经改变了。抓住你可能利用的新问题。您可以按照这些思路使用:

try {
final Intent vsInt = new Intent(Intent.ACTION_MAIN);
vsInt.setComponent(new ComponentName("com.google.android.voicesearch",
                            "com.google.android.voicesearch.VoiceSearchPreferences"));
vsInt.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
ctx.startActivity(vsInt);

} catch (final Exception e) {

try {
final Intent vsjInt = new Intent(Intent.ACTION_MAIN);
vsjInt.setComponent(new ComponentName("com.google.android.googlequicksearchbox", "com.google.android.voicesearch.VoiceSearchPreferences"));
vsjInt.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
ctx.startActivity(vsjInt);

} catch (final Exception e1) {
e1.printStackTrace();
}
}

@brandall的回答对我来说是第5.1条,如另一个组成部分的名称,则用于这里的语音识别环境。

/**
 * Open speech recognition settings activity
 *
 * @return true in case activity was launched, false otherwise
 **/
public boolean openSpeechRecognitionSettings() {
    Intent intent = new Intent(Intent.ACTION_MAIN);
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    boolean started = false;
    ComponentName[] components = new ComponentName[]{
            new ComponentName("com.google.android.googlequicksearchbox", "com.google.android.apps.gsa.settingsui.VoiceSearchPreferences"),
            new ComponentName("com.google.android.voicesearch", "com.google.android.voicesearch.VoiceSearchPreferences"),
            new ComponentName("com.google.android.googlequicksearchbox", "com.google.android.voicesearch.VoiceSearchPreferences"),
            new ComponentName("com.google.android.googlequicksearchbox", "com.google.android.apps.gsa.velvet.ui.settings.VoiceSearchPreferences")
    };
    for (ComponentName componentName : components) {
        try {
            intent.setComponent(componentName);
            startActivity(intent);
            started = true;
            break;
        } catch (final Exception e) {
            Timber.e(e, null);
        }
    }
    return started;
}
