enable/disable keyboard sound and vibration progra

Question

I'm trying to find a way to disable and enable keyboard sound and vibration when tapping keys. I've searched on Stack Overflow and other Android Forums but i didn't found any result.

I've tried AudioManager to enable vibrate mode, but i want to activate the vibrate mode and sound on keyboard.

audioManager.setRingerMode(AudioManager.RINGER_MODE_VIBRATE);
audioManager.setVibrateSetting(AudioManager.VIBRATE_TYPE_RINGER, 
                AudioManager.VIBRATE_SETTING_ON);

Is there any way how to change android.provider.Settings for keyboard sound and vibration ?

Answer 1

Have a look at How to disable default sound effects for all my application or activity for disabling tap-sounds.

To disable Haptic feedback and touch sounds programmatically have a look at http://developer.android.com/reference/android/view/View.html#setHapticFeedbackEnabled(boolean) http://developer.android.com/reference/android/view/View.html#setSoundEffectsEnabled(boolean)

Easier done is by defining the following in your styles.xml

<!-- Application theme. -->
<style name="AppTheme" parent="@android:style/Theme.NoTitleBar.Fullscreen">
    <item name="android:soundEffectsEnabled">false</item>
    <item name="android:hapticFeedbackEnabled">false</item>
</style>

and in your manifest.xml

<application [...] android:theme="@style/AppTheme" >

Answer 2

Yes, You can do this if you have root access. Its a lengthy process but you can do this :

Step : 1 Create xml file named com.android.inputmethod.latin_preferences.xml and save in assets.

com.android.inputmethod.latin_preferences.xml

<?xml version='1.0' encoding='utf-8' standalone='yes' ?>
<map>
    <boolean name="popup_on" value="false" />
    <string name="auto_correction_threshold">1</string>
    <boolean name="pref_enable_metrics_logging" value="true" />
    <boolean name="pref_voice_input_key" value="true" />
    <boolean name="pref_key_use_personalized_dicts" value="true" />
    <boolean name="pref_key_block_potentially_offensive" value="true" />
    <int name="last_shown_emoji_category_id" value="1" />
    <boolean name="sound_on" value="false" />
    <string name="emoji_recent_keys">[{&quot;Integer&quot;:128533}]</string>
    <boolean name="auto_cap" value="true" />
    <boolean name="show_suggestions" value="true" />
    <boolean name="pref_key_use_contacts_dict" value="true" />
    <boolean name="next_word_prediction" value="true" />
    <boolean name="pref_key_use_double_space_period" value="true" />
    <int name="emoji_category_last_typed_id1" value="0" />
    <boolean name="vibrate_on" value="false" />
</map>

Step 2 : Copy this file into your application folder (anywhere where you can access) using asset manager for that you need

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

this function will copy file from assets

public static void copyAssets(Context context, String assetPath, String outFilename) {
        AssetManager assetManager = context.getAssets();
        InputStream in = null;
        OutputStream out = null;
        try {
            in = assetManager.open(assetPath);
            File outFile = new File(context.getExternalFilesDir(null), outFilename);

            out = new FileOutputStream(outFile);
            copyFile(in, out);
        } catch (IOException e) {
            Log.e(TAG, "Failed to copy asset: " + outFilename, e);
        } finally {
            if (in != null) {
                try {
                    in.close();
                } catch (IOException e) {
                }
            }
            if (out != null) {
                try {
                    out.close();
                } catch (IOException e) {
                }
            }
        }
    }

public static void copyFile(InputStream in, OutputStream out) throws IOException {
        byte[] buffer = new byte[1024];
        int read;
        while ((read = in.read(buffer)) != -1) {
            out.write(buffer, 0, read);
        }
    }

Step 3 : overwrite the system preference file system path (destPath) is /data/data/com.android.inputmethod.latin/shared_prefs

public static void copyToSystem(final String sourceFilePath, final String destPath) {
        Thread background = new Thread(new Runnable() {

            @Override
            public void run() {
                try {
                    Process process = Runtime.getRuntime().exec("su");
                    DataOutputStream os = new DataOutputStream(process.getOutputStream());
//                    
                    os.writeBytes("cp -f " + sourceFilePath + " " + destPath + "\n");
                    os.flush();
                    os.writeBytes("exit\n");
                    os.flush();
                    process.waitFor();
                    process.waitFor();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                    Log.e(TAG, e.toString());
                } catch (IOException e) {
                    e.printStackTrace();
                    Log.e(TAG, e.toString());
                }
            }
        });
        background.start();
    }

Step 4 : Reboot device

That's all done. These step will off key press sound and key press vibration

Answer 3

As per your comments:

i'm talking about the default keyboard in android , i want to have the ability to disable / enable keyboard sound and vibration when user tap a key in keyboard,( like in Settings of Keyboard )

&

i'm talking about soft keyboard, like in SAMSUNG GALAXY S2 , HTC ONE ...etc

AFAIK, you can not accomplish this as each input method keeps its sound/vibration preference values internally. See for example Android (AOSP) IMe (as of this writing lines 30~39):

    <CheckBoxPreference
        android:key="vibrate_on"
        android:title="@string/vibrate_on_keypress"
        android:defaultValue="@bool/config_default_vibration_enabled"
        android:persistent="true" />
    <CheckBoxPreference
        android:key="sound_on"
        android:title="@string/sound_on_keypress"
        android:defaultValue="@bool/config_default_sound_enabled"
        android:persistent="true" />

As you can see it stores the vibrate/sound values in its shared preference. That applies to most of IMe in the market. Hence, you can not control vibrate/sound effect for all IMe's from single point.
